Description
- The present invention relates to an apparatus and method for harvesting vessels, especially veins, for use in bypass grafting surgical procedures.
- Atherosclerosis is a disease that affects hundreds of thousand of people each year. The disease can occur anywhere throughout the body including the lower extremities, the carotid arteries and the heart. When it affects the blood supply to the heart it is called coronary artery disease. Vascular complications produced by atherosclerosis, such as stenosis, aneurysm, rupture or occlusion oftentimes call for surgical intervention. If the disease is extensive, the affected artery or vessel is no longer reliable and is often replaced or bypassed around by a bypass graft, usually referred to as an “autograft.” To this end, the involved section of the vessel is bypassed with an autograft surgically attached proximal to the lesion and at a point distal to the lesion to provide a bypass path for blood flow. In a patient who undergoes coronary artery bypass grafting (CABG) surgery, a non-critical vessel (artery or vein) is harvested from elsewhere in the body and is sewn into place in such a manner that reestablishes the flow of blood to the heart region that had lost or diminished its supply of blood because of the atherosclerotic lesion.
- The saphenous vein in the leg is a vessel that is commonly harvested for use as a bypass graft in coronary artery surgery. It is also common to use the saphenous vein for bypass surgery in the lower extremity to bypass lesions in the femeral or popliteal arteries. However, typical procedures for harvesting a saphenous vein autograft are tedious, time consuming, and cause undesirable patient trauma. In one harvesting procedure, an incision is made along the leg for a length corresponding to the length of the autograft required, wherein the vein is transected and is stripped from the leg. The incision then must be sutured or stapled along its length. In some patients, the incision must be made along the entire length of the leg. The surgery required for harvesting a vessel in this manner is traumatic to the patient, increases recovery time, increases the patient's hospital confinement, and adds to the cost of the coronary artery surgery.
- Another method of harvesting a saphenous vein is by use of an endoscope. In this method, a few small incisions are made on the leg over the saphenous vein. The saphenous vein is transected and ligated at its ends and the endoscope is inserted into the small incisions. While visualizing the vein with the endoscope, the entire length of the vein is harvested by slow dissection. The endoscope is advanced under the skin along the saphenous vein's length while transecting and ligating its connecting branches until the entire segment of the saphenous vein is free and is able to be removed. This method is more advantageous to the patient in that only a few small incisions are made and much less scarring occurs. However, the endoscopic harvesting of the vein is a difficult procedure and takes a substantial amount of time. The increased time in the operating room increases the cost of the procedure and increases the risk of infection and complications to the patient.
- Other vessels are often used as well in bypass surgical procedures. For example, the radial arteries are often used as coronary conduits. The lesser saphenous, basilic, and cephalic veins are also used.
- Accordingly, it would be highly desirable to provide a less invasive procedure for harvesting vessels, especially the saphenous vein, which avoids the need for a long incision, is easy to use, and does not require a substantial amount of time to complete.
- The present invention provides a fast, uniform, and inexpensive way to harvest a vessel for bypass surgery. An embodiment of the present invention comprises an internal stenting catheter with proximal and distal ends, a sheath catheter with proximal and distal ends, and a cylindrical cutting tube that is attachable to the distal end of the sheath catheter. The stenting catheter is located within the sheath catheter and is used as a stent to straighten out the vein and to guide the cylindrical cutting tube around the vein. The sheath catheter is used to pull the cylindrical cutting tube under the skin and around the vein, cutting the side branches as it is pulled along the length of the vein and collecting the vein within the lumen of the cylindrical cutting tube.
- The present invention is used in the following manner. The patient is prepared for surgery in standard manner and placed under proper anesthesia (local or general). A small skin incision is made at the distal end of the vessel. Next, a small skin incision is made at the proximal end of the vessel. Using a cut-down technique, for example the Seldinger Technique, the vessel is isolated and the vessel is ligated. The stenting catheter and the sheath catheter are then introduced within the vessel through the distal incision at the vessel's distal end and advanced to the vessel's proximal end where it exits the vessel and the proximal skin incision. Next, the cylindrical cutting tube is placed over the distal end of the sheath catheter and locked into place. The proximal and distal ends of the stenting catheter which are outside of the vessel and the skin are then placed into clamping devices and tension is placed on the stenting catheter until the catheter is straight. The cylindrical cutting tube is then advanced through the proximal skin incision and around the proximal end of the vessel to be harvested. The sheath catheter is used to pull the cutting tube distally down around the vessel cutting connective tissue and branches along the way. The vessel being harvested is collected within the collection lumen of the cutting tube as it is being cut free from the connective tissue and branches. Once the cutting tube has been pulled completely through the course of the vessel, the cutting tube is then removed from the distal skin incision. The cutting tube is then cut free from the stenting catheter and the remains of peel-away catheter. The harvested vessel is then removed from the lumen of the cutting tube, dilated, and the cut branches are sutured or clipped according to standard bypass grafting techniques. The vessel is now ready for the bypass grafting procedure (CABG or other bypass surgery). The area where the vessel was removed is then wrapped with elastic wraps to seal the cut edges and minimize swelling. At the end of the bypass procedure, the skin incisions are cleaned, any hematomas are expelled, and the wounds are closed.

FIGS. 1 and 2 , the vessel harvester of the present invention is illustrated. The vessel harvester comprises astenting catheter 11 with proximal and distal ends, asheath catheter 13 with proximal and distal ends, and acylindrical cutting tube 15 with a proximalcutting edge 43 and a distal connectingport 33. The stenting catheter is located within the lumen of the sheath catheter. Both the stenting catheter and the sheath catheter are illustrated within the lumen of avessel 17 withside branches 18. The cutting tube, on the other hand, is located around the outside of the vessel. The cutting tube is connectably attached to thedistal end 35 of the sheath catheter via the connecting port and the connectingprongs - The stenting
catheter 11 can be made out of an appropriately strong biocompatible material. The catheter can be made from an extruded biocompatible plastic such as polyurethane or polyethyl terephtalate, a biocompatible metal such as surgical stainless steel wire or wire braids, a combination of wire and plastic, or other readily available materials known in the art. The catheter has to have enough flexibility to navigate the curved path of the vessel to be harvested, but also needs to have enough strength such that when axial tension is applied to straighten out the vessel, the catheter will not break. The size of the stenting catheter can vary depending on the length of the vessel to be harvested. For the greater saphenous vein, the length of the stenting catheter is about 36 to about 48 inches. For smaller veins, such as the lesser saphenous vein, the length of the stenting catheter is about 12 to about 36 inches. The diameter of the stenting catheter is about 1 to about 3 mm. The diameter has to be small enough to fit within the sheath catheter. Additionally, the catheter has to be fairly lubricious to allow for the sheath catheter to easily travel along its axial length when the vessel is being harvested. To this end the stenting catheter can be coated with a lubricious surface such as Teflon® or the like. The distal end of the stenting tube is provided with a roundedbullet nose member 39 for ease in threading the stenting catheter through the vein to be harvested. Additionally, the bullet nose can be used to fit in a clampingmember 19 for placing tension on the stenting catheter once it has been threaded through the vein. The proximal end of the stenting catheter can also be placed in a clampingmember 21 for opposing the tension placed by clampingmember 19. - In the preferred embodiment, the
sheath catheter 13 is a peel-away catheter which has twopull tabs 23 that have twonotches 24 located on opposite sides for easy separation. Typical peel-away catheters have axial scoring along their length such that the catheter can peel away into two halves. It is contemplated in the present invention that this type of scoring can be used. If this type of scoring is used, then when the peel-away catheter is pulled apart, the cuttingtube 15 attached to the distal end of the peel awaycatheter 35 is pulled straight down the stenting catheter. However, it is also contemplated in the present invention that the cutting tube is more effective when it is rotated while being pulled down. To achieve this rotation, the scoring 25 of the peel-away catheter is in a spiral configuration. Thus, when the peel-away catheter is pulled apart at its proximal end, the distal end of the peel-away catheter rotates, which in turn causes the rotation of the cutting tube. The peel away catheter can be made out of biocompatible plastics such as polyurethane, PET, or the like by extrusion and/or molding techniques or other means well known in the art. The peel-away catheter can also be reinforced with stainless steel wire to provide it strength for the rotational force needed to rotate the cutting tube within the patient. The size of the peel-away catheter can vary depending on the length of the vein to be harvested. For the greater saphenous vein, the length of the peel-away catheter is about 24 to about 48 inches. For smaller veins, such as the lesser saphenous vein, the length of the peel-away catheter is about 6 to about 36 inches. The diameter of the peel-away catheter is about 2 to about 4 mm. - The
cylindrical cutting tube 15 is a hollow tube with avein collecting lumen 47 in the proximal portion of the tube. The proximal edge of the cutting tube is a sharpcircular blade 43 which can cut connective tissue and vessel branches. The blade is created bybevel 45 which is bevelled radially outward instead of inward. This beveling configuration prevents the cutting tube from cutting the vessel to be harvest if the tube axially torques and rubs against the side of the vessel. Instead, the cutting edge acts like a razor blade traveling along the surface of the vessel and cutting the connective tissue and vessel branches. The distal end of the cutting tube has asmaller lumen 49 for closely fitting over the peel-away catheter. Turning now toFIGS. 2 and 3 , thesmaller lumen 49 is provided with ataper 51 near the distal end which then narrows to thedistal opening 33. The distal end of the cutting tube is also provided with two connectingchannels distal lumen 33. The peel-awaysheath catheter 13 is provided with ataper 59 to asmaller lumen 60 for closely fitting over the stentingcatheter 11. Additionally, the peel-away catheter's outer diameter through this section remains the same until thetaper 63 nearer the distal end which fits within thetaper 51 of the cutting tube. This provides athick area 61 where the peel-away catheter is thicker and stiffer to support the cutting tube and track over the stenting catheter to help prevent axial torqueing of the cutting tube while it is pulled down along the vessel. The peel-away catheter is also provided with connectingprongs ports channel 34 in the cutting tube (seeFIG. 1 ) and then rotated 90 degrees for insertion into the connecting ports. Once the connecting prongs are inserted into the connecting channels, pulling apart the peel-away catheter allows for the pulling of the cutting tube down the vessel and the rotation of the cutting tube if a spiral scoring of the peel-away catheter is used. - The cutting tube can come in different sizes depending on the size and length of the vessel to be harvested. For the greater saphenous vein, the length of the cutting tube is about 7 to about 20 cm and the length of the vessel collecting lumen is about 5 to about 15 cm. For smaller vessels, such as the lesser saphenous vein or the radial artery, the length of the cutting tube is about 5 to about 15 cm and the length of the vessel collecting lumen is about 3 to about 10 cm. The diameter of the cutting tube can vary from about 3 to about 15 mm depending on the size of the vessel being harvested.
- Turning now to
FIG. 4 an alternate embodiment is illustrated in cross-section. In this embodiment, thesheath catheter 13 is a peel-away catheter which is longitudinally scored and has the same outer diameter until the very distal end where abeveled flange 75 is provided. The flange is inserted through asmall lumen 71 of the cuttingtube 15 until it rests within alarger lumen 73 of the cutting tube at its distal end. In the center of the peel away catheter is a stentingcatheter 11 with abullet nose member 39 at its distal end. Additionally, within the center of the peel away catheter are a plurality of guide wires (two being illustrated 77 and 79) for helping to keep the cutting tube aligned when it is being pulled down under the skin of the patient. The guide wires are secured at both ends of the patient in clampingmember lumen 89 in alarger bullet member 81 for actually pulling the cutting tube under the skin. The guide wires travel though thebullet member 81 insmall channels - To harvest the vessel using the embodiment of
FIG. 4 , the stenting catheter is used to pull the cutting tube while the peel away catheter is used as a sheath for covering the guide wires and stenting catheter during the procedure. Thevessel 17 is collected in thelarge lumen 47 of the cutting tube and theside branches 18 are cut with thecutting edge 43. - Turning now to
FIGS. 5-9 , the method of harvesting a vessel is illustrated.FIG. 5 schematically illustrates a greatersaphenous vein 17 withside branches 18 in a leg of a patient. As can be seen, the greater saphenous vein is a curved vein located on the medial to anterior parts of the leg. Twoskin incisions FIG. 6 ). As would be apparent, one skin incision is located at thedistal end 93 of the vein and one is at theproximal end 91 of the vein. The location of the skin incisions can vary depending on the length of saphenous vein needed. Using a cut-down procedure such as the Seldinger technique, the saphenous vein is isolated and ligated. - Turning now to
FIG. 7 , the stentingcatheter 11 is then inserted into thesheath catheter 13 which is then inserted into the proximal end of the vein throughincision 93 and then exits the vein at thedistal incision 91. As illustrated inFIG. 8 , the cutting tube is then inserted over the distal end of the peel-away catheter and locked into place using connectingtabs members saphenous vein 17 becomes straight. The cuttingtube 15 is then inserted under the skin through theskin incision 91. The sheath catheter is a peel away catheter which is then broken apart at thetabs 23 on the proximal end and pulled apart at the serrations. While pulling the peel-away catheter apart, the cutting tube is pulled under the skin of the patient around thesaphenous vein 17. As the cutting tube is being pulled,side branches 18 are cut by thecutting edge 43 of the cutting tube. If needed, the cutting tube can be manually manipulated from outside the skin of the patient to help keep it straight to prevent axial torquing and continue the harvesting of the vein. Eventually, the cutting tube is pulled all the way to theproximal incision 93 where the tube is removed from the patient. The peel-away catheter and the stenting catheter are then cut and removed from the cutting tube. The vein is then removed from the cutting tube and the cut side branches are sutured or clamped. The vein is then prepared for being a bypass conduit using standard techniques and then is used as a bypass conduit as needed. - The skin incisions 91 and 93 are then closed using standard surgical closure techniques and the leg of the patient is then wrapped with tight leg wrapping to seal the cut vein branches. The leg is monitored to insure that there is appropriate blood flow and proper recovery. If need be, hematomas are removed.
- Similar methods are used for harvesting other vessels such as the lesor saphenous vein, the basilic vein, the cephalic vein, the radial artery and the like.
- The vein harvesting device and method of the present invention may be embodied in other specific forms without departing from the teachings or essential characteristics of the invention. The described embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore to be embraced therein.
