Description
    CROSS REFERENCE TO RELATED APPLICATIONS
  • [0001]
    The present application is a continuation-in-part application of co-pending patent application Ser. No. 09/087,511 filed on May 29, 1998, which is a continuation-in-part application of Ser. No. 08/936,184 filed on Sep. 17, 1997 by the inventors of the present application. The disclosure of the just-referenced patent applications are incorporated herein by reference.
  • TECHNICAL FIELD OF THE INVENTION
  • [0002]
    The present invention relates to the general art of cardiac surgery, and to the particular field of heart retractors used in beating heart surgery.
  • BACKGROUND OF THE INVENTION
  • [0003]
    There are as many as 300,000 coronary bypass graft procedures performed annually in the United States. Each of those procedures may include one or more graft vessels. Currently, each graft vessel must be hand sutured. As many as four or more grafts are placed in a procedure. Until recently, coronary artery bypass procedures have been performed with the patient on cardiopulmonary bypass whereby the heart is stopped with cardioplegia and the surgery performed on an exposed and still heart.
  • [0004]
    The previous applications disclosed means and methods for manipulating the heart during cardiac surgery whereby the heart can be located and oriented into the most advantageous position and orientation for beating heart surgery. Reference to those applications is made for a more complete discussion of the means and methods described.
  • [0005]
    Most particularly, the means and method described in those applications include using a gross support to support the heart and a means for engaging a selected section of the heart to immobilize that selected section as a surgery target while permitting non-engaged sections of the heart to move in a manner whereby essentially unabated cardiac output is maintained while the heart is regionally immobilized.
  • [0006]
    The gross support means disclosed in the application filed on May 29, 1998 includes a flexible cup that can move in a plurality of planes and which has a flexible rim for engaging the heart. The cup is releasably attached to the heart. One means for releasably attaching the cup to the heart includes suction applied by the cup to the heart. Suction is the best mode disclosed in the just-mentioned patent application.
  • [0007]
    As suction is readily available in most operating rooms, this is an effective means for releasably attaching the elements to the heart. However, this means can be improved.
  • [0008]
    Therefore, there is a need for a means and method for improving the releasable attachment between the elements of the heart manipulation system disclosed in the incorporated patent applications and the heart.
  • [0009]
    The suction system disclosed in the incorporated patent applications can also benefit by being backed up whereby the heart will remain in the desired position and orientation even if vacuum is lost or degraded.
  • [0010]
    Therefore, there is a need to provide a means for backing up the vacuum system used in the incorporated patent applications to releasably attach the elements of the system to the heart.
  • [0011]
    Operation of the heart was discussed in the incorporated patent applications and reference is made thereto for such disclosure so it will not be repeated here.
  • [0012]
    Recently, there has been interest in minimally invasive coronary bypass surgery. This is not surprising since a median sternotomy and a run on the cardiopulmonary bypass pump are not well tolerated by some patients, combined with the added cost of coronary bypass equipment and staff. The procedure results in considerable recovery time and is associated with a risk of death and major complication. While the ultimate goal is to provide bypass to all vessels by port access (like gallbladder surgery) and to eliminate the need for cardiopulmonary bypass, a more limited but reasonable option for the next number or years will be to perform bypass off pump with an incision (sternotomy or thoracotomy). A tool which could allow performance of multivessel off pump bypass would be most helpful.
  • [0013]
    Therefore, the incorporated patent applications disclosed a heart retractor which will support the heart in position for minimally invasive coronary bypass surgery of coronary arteries, including the circumflex coronary artery, in a manner that will not damage the heart yet will provide easy access to the surgical target without requiring the heart to be stopped yet without unduly constraining the heart.
  • [0014]
    These means and methods can also be improved by having additional means and methods for releasably attaching the elements of the systems to the heart during minimally invasive surgery.
  • OBJECTS OF THE INVENTION
  • [0015]
    It is main object of the present invention to improve the performance of the system for manipulating a heart during cardiac surgery which was disclosed in the incorporated patent applications.
  • [0016]
    It is-another object of the present invention to improve the performance of the retractors disclosed in the parent disclosures.
  • [0017]
    It is another object of the present invention to improve the performance of the retractors disclosed in the parent disclosures by providing additional means for releasably attaching the elements of those systems to the heart.
  • [0018]
    It is a more specific object of the present invention to provide mechanical means for releasably attaching elements of a system for manipulating a heart during cardiac surgery.
  • [0019]
    It is a more specific object of the present invention to provide adhesive means for releasably attaching elements of a system for manipulating a heart during cardiac surgery.
  • [0020]
    The objects set forth in the incorporated applications are incorporated herein by reference.
  • SUMMARY OF THE INVENTION
  • [0021]
    These, and other, objects are achieved by providing mechanical and/or adhesive means for releasably attaching the elements of a system for manipulating a heart during cardiac surgery.

    [0029]FIG. 8 illustrates an adhesive means for attaching an element of the heart manipulation system to the heart.
  • DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT OF THE INVENTION
  • [0030]
    The operation of a heart was discussed in the incorporated patent applications, and reference thereto is made for such discussion. Furthermore, the discussion of the various elements of the heart manipulation system were also fully discussed in the incorporated material, and reference is made thereto.
  • [0031]
    The improvement in the heart manipulation system which is the subject of the present invention utilizes either mechanical or adhesive means to releasably attach an element of the heart manipulation system to the heart. These means can be used in place of or in addition to the means disclosed in the incorporated patent applications.
  • [0032]
    As shown in FIG. 1, a special cup 10 is used to attach various elements of the heart manipulation system to the beating heart H in a manner that permits the heart and the myocardium to move during heart operation without unduly affecting the attachment of the element to the heart. The cup 10 can be adapted to apply suction to the heart, but need not and can be designed to have several degrees of freedom whereby the heart can move without undue restriction from cup 10. Specifically, cup 10 has a flexible wall 12 and a flexible rim 14 and is attached to an arm 16 at an apex portion 18 of the cup. The flexible wall permits the cup to move in a plurality of planes so the heart can move relative to arm 16.
  • [0033]
    The means for releasably attaching cup 10 to the heart can included mechanical means. As used herein, the term “mechanical means” includes sutures, staples and other such mechanical elements and fasteners as opposed to suction and chemical means.
  • [0034]
    One form of mechanical means for releasably attaching elements of the heart manipulation system to the heart includes sutures 20. Sutures 20 include needles 22 which are threaded through the heart manipulation system element, such as cup 10, and then through the heart tissue, and then back through the heart tissue and back through the system element and out of the patient. Sutures 20 can also include an element, such as pledget 24 for holding the suture in place on the heart and for spreading out the force applied by the suture to the heart tissue. The sutures can be set in any manner known to those skilled in the art. Once set, the sutures are tied off and then serve as a means for attaching the system element to the heart. The sutures are cut when the element is to be released from the heart.
  • [0035]
    As shown in FIG. 1, the element, such as cup 10, can include extensions, such as extension 26, having suture-accommodating holes 28 defined therethrough. However, the element need not include the extensions, and the holes 28 can be defined in the element itself or the sutures can be drawn through the element without the need of such holes 28 without departing from the scope of the present disclosure.
  • [0036]
    While the sutures are shown in FIG. 2 as extending through an extension on the element, these sutures could be sewn through the element itself without departing from the scope of the present invention. In fact, the sutures need not be located near the perimeter of the element, but could be placed in any suitable location on the element without departing from the scope of the present invention. The sutures can be manipulated in any suitable manner and can take the form of any suture known to those skilled in the art without departing from the scope of the present disclosure. Those skilled in the art will understand what type of suture works best in any given application based on their own knowledge and the teaching of the present invention and the present disclosure. Accordingly, the term “suture” is intended to cover any suture known to those skilled in the art that will work in the application disclosed herein.
  • [0037]
    Yet another form of mechanical means for releasably attaching an element of the heart manipulation system to the heart is shown in FIGS. 3 and 4 as including a staple 30. Staple 30 is set and formed according to known procedures from the unformed condition shown in FIG. 3 to the formed configuration shown in FIG. 4. Staples, such as those used to close skin can also be used and still be within the teaching of this invention. An extension 32 is included on the heart manipulation system element, such as cup 10, and has a distal end 34 with a neck 36 defined therein. A tab 38 is located on the distal end and includes a groove 40 that permits a portion 41 of a staple removing tool, such as tool 42 shown in FIG. 5, to be inserted beneath the staple for removing that staple from the formed configuration shown in FIG. 4. Once the staples are removed, the element can be released from attachment to the heart. Portion 41 is manipulated by handle 44 via pivot 46 to unform the staple to release the staple from the heart.
  • [0038]
    Yet another form of mechanical means is illustrated in FIGS. 6 and 7 as a plurality of anchor wires 50 located inside the element being releasably attached to heart H. Each anchor wire 50 include a curled, pre-shaped end 52 which curls up inside the heart tissue once the wire is inserted into the tissue to fasten the element to the heart. The anchor wires extend inside the element from apex 18 to and out of rim 14 and the curled bias thereof is overcome by the inside surface of the element as indicated at end 52′ shown in FIG. 6. The wire curls as it exits the element and enters the heart tissue. A plurality of wires can be used as indicated in FIG. 7, and the wires can be used in conjunction with, or in place of, suction and/or other mechanical means, such as the sutures and/or staples disclosed hereinabove.
  • [0039]
    An adhesive means can also be used to releasably attach the heart manipulation system element to the heart. As shown in FIG. 8, surgical adhesive 60 can be placed on the element near rim 14 to releasably attach the element to heart H. A wick 62 can be included in the element to ensure the delivery of bonding activators or de-bonding agents directly to the adhesive layer. Solvent can be applied to the adhesive via wick 62 to release the adhesive from the heart as will occur to those skilled in the art based on the teaching of the present disclosure. Any suitable surgical adhesive can be used and those skilled in the art will understand what adhesive is best based on the teaching of the present disclosure. In addition, heat or light or moisture sensitive adhesives could be used to releasably attach elements of the heart manipulation system to the heart without departing from the scope of the present disclosure. The particular adhesive forms no part of the present invention and thus will not be discussed.
  • [0040]
    As is the case above, the adhesive can be used in conjunction with or in place of the suction and/or the mechanical means for releasably attaching the element to the heart.
  • [0041]
    It is understood that while certain forms of the present invention have been illustrated and described herein, it is not to be limited to the specific forms or arrangements of parts described and shown. For example, tissue-gripping needles on a pad can be used to attach the elements of the heart manipulation system to the heart, such tissue-grippng needles would be self-contained and quickly deployed. These needles would work in the manner of a skin stapler but would be more convenient since they could deployed by a mechanism on the attachment element, Such needles can be anchored to the element being attached to the heart, and released using tools similar to those used to remove small suture needles in other applications or have integrated deployment or retraction means. The needles need not be formed with a formg device but can also be of a pre-formed configuration, such as a helix, or the like and can be self-tapped into the heart. The heart attachment system is not dependent on suction alone and, as can be understood from the foregoing teaching, can include various other means in addition to, or instead of, suction. Combinations of the various mechanical and adhesive and suction means can be used as will be understood from the teaching of this disclosure.
