Abstract
A directional application device for applying one or more components to a desired internal site in a human or animal within a range of angular directions is disclosed.
Description
Directional Endoscopic Delivery of Material Field of the Invention This invention relates to an applicator for the directional delivery of one or more materials to a desired internal site in a human or animal.
SUMlARY OF THE INVENTION
In accordance with the present invention a directional application system for applying one or more components to a desired internal site in a human or animal within a range of angular directions is disclosed. The present system comprises a source of the components; means for fluid communication integral at a first end with the source of components and at a second end with a directional nozzle; and a directional nozzle comprising an inner tube of resilient material integral at a first end with the second end of the fluid communication means and having a nozzle at a second end, the second end being bent to the maximum angle within the desired range of directions;
and an outer tube of a material more rigid than the inner tube and having an opening at one end to allow the inner tube to slidably project through the opening, whereby the amount of projection of the bent end of the inner tubing through the opening determines the angular direction of the nozzle.
Brief Description of the Drawings Figure 1 shows a section of resilient tube with the bent or curved nozzle end.
Figures 2-4 illustrate the different range of angular delivery possible depending upon the extent to which the resilient tube is projected out of or retracted into the second end of the rigid tube. Sliding means (or projecting/retracting means) can be provided at or near the first end of the rigid tube.
DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
Thus, the device of the present invention may be used to deliver materials endoscopically, i.e., via a body opening or duct to an organ, or through a surgical opening typically fitted with a trocar, e.g., laparoscopically or thorascopically, that is, into the abdominal or thoracic cavity. The invention comprises a directional dispensing or delivery device comprising an inner tube 26 of a resilient material integral at a first end with a source or sources of the one or more materials to be delivered and having a nozzle at a second end. The second or nozzle end 28 of the resilient material is bent or curved to the maximum angle within a desired range of angular directions for delivery of the materials. Figure 1 depicts a resilient inner tube with a bent nozzle end generally indicated by 10, and a reduced tip 12. The inner tube 26 is positioned slidably within an outer tube 27 of a more rigid material such that the user can hold a first end of the rigid outer tube 27 (which may be formed into a convenient handle 25) and such that the second end of the resilient tube 26 can extend out of an opening at a second end of the rigid tube 27. The second end of the more rigid tube 27 is positioned in the vicinity of the site to receive the desired materials, e.g., through the trocar. Means 22 are provided to slide the resilient tube 26 within the rigid tube 27 so as to vary the length of the resilient tube 26 projecting beyond the second end of the rigid tube 27. In doing this, the bent or curved nozzle (second) end 28 of the resilient tube 26 will assume, or be positioned at, varying angles to deliver or dispense the materials to a desired internal location. Full projection of resilient inner tube 26 is generally shown by arrow 50. Partial projection of resilient inner tube 26 is generally shown by arrow 40.
Retracted resilient inner tube 26 is generally shown by arrow 30.
The device and method of the present invention can be used for the endoscopic, laparoscopic or thorascopic delivery of any materials. The direction of endoscopic delivery is generally indicated by reference character 20. They are conveniently employed to deliver components, e.g., liquid components, to a surgical site to form or deposit a polymer, e.g., a biopolymer. The present invention is particularly useful in the delivery of fibrin sealant components.
Accordingly, the resilient inner tube 26 may comprise separate tubes or one tube with multiple discrete channels to deliver a fibrinogen component and a component capable of converting fibrinogen to a fibrin polymer (sealant). Such a component is thrombin or another enzyme which catalyzes the cleavage of fibrinopeptides A and/or B from fibrinogen. According to U.S.
5,739,288 the fibrin sealant forming components (which are delivered in discrete tubes or channels) may also be a fibrin monomer component (which can be fibrin I, fibrin II or des RR
fibrin) and a component which will polymerize the fibrin component to form the sealant. In the case where the fibrin component is at low pH, i.e., pH4, the second component can be, for example, a pHlO buffer which facilitates the fibrin polymerization. The inner tube 26 can be of a plastic material which can be bent or curved and which will strive to retain such a bend or curve. That is, the material of the inner tube 26 needs to have some "memory" such that if it is initially bent or deformed to a desired maximum angle by known means, it will substantially return to that angle after being forced straight. Polyethylene multilumen tubing such as low density polyethylene tubing commercially available from the Putnam Company is suitable. Those multilumen tubings are preferably (each lumen) below about 500 microns in diameter, i.e., more preferably at or below 300 microns in diameter and most preferably the tubing has a reduced diameter portion such as described in WO 98/20931, such that the lumen diameters are about 120-150 microns in diameter. This involves heating and drawing the end of the tubing to produce a reduced diameter.
The resilient inner tube 26 is in fluid communication directly or indirectly with sources of the components to be delivered. The sources of material to be delivered is generally indicated by the arrow at reference character 21. By indirectly is meant that the resilient tubing is in fact connected to a separate tubing or conduit which is, in turn, connected to the sources. Preferably the source of components are at a remote location and connected by tubing. This means that the user does not have to hold the sources of components in his/her hand and greater ease of use is provided. This is disclosed in WO 98/20931 and WO 97/20585. As mentioned in those patents, the sources of components are in a remote location as part of a mechanical or electromechanical drive unit to deliver the components from the sources to, and out the nozzle of, the present device. Delivery of the components from the sources, through the means for fluid communication and out of the directional nozzle, can be accomplished using a foot pedal which signals the drive unit. Alternatively, the present device may incorporate a handle for the user which may further include an actuator, button or trigger to actuate dispensing of the components.
Of course, the device of the present invention can be incorporated onto the delivery end of any medical component applicator, such as double barreled syringes, known in the art to apply fibrin sealants.
The more rigid outer tubing 27 can be any material more rigid than the resilient inner tube 26. For example, medical grade plastics can be used and these are well known in the art. Examples include polypropylene or polycarbonate but can be any plastic so long as the outer tube is sufficiently rigid so that the inner bent resilient tube 26 is "straightened"
when drawn back into the outer tube 27. The outer tube can also be metal, e.g., stainless steel or other metal useful for internal medical devices.
The dimensions of the outer tube 27 are adapted for their intended purpose. For endoscopic use the outer tube needs to be comparable to other endoscopic tubing for insertion into canals, e.g., esophagus, colon, etc., or into other body apertures or cavities. The laparoscopic use the outer tube needs to fit through a trocar. In practice, generally, the outer tube 27 (with the inner tube 26 withdrawn 30 as in Figure 2) is inserted into the area where component delivery is desired. Thereafter, the inner tube 26 is extended sufficiently to provide the desired angular directional spray or delivery of components as shown in Figures 3 and 4. This can be used in conjunction with known endoscopic or laparoscopic cameras or optical equipment to observe/confirm the procedure.
As can be seen from Figures 2-4, in a preferred embodiment the present device includes a handle 25 which can be a hollow tube-like part, cylindrical or otherwise. The rigid outer tube 27 extends from a first end of the handle as shown in the figures. A means for sliding 22 (or extending and withdrawing) the resilient inner tube 26 within the outer tube 27 is also a rigid material which is secured to the resilient tube, for example, by 0-rings 23 or other convenient fastening means. The means for sliding 22 is adapted to slide in and out of a recess 24 within a second end of the handle 25. This provides that when the means for sliding 22 is slid in or out of the recess 24 of the handle 25, the nozzle end 28 of the resilient tube 26 will extend or withdraw from the rigid outer tube 27 as shown.
The present device is extremely useful in any endoscopic, laparoscopic, thorascopic or similar procedure where directional angular applications of components, e.g., fibrin sealant components, is required. It can be used in nearly all "minimally" invasive procedures and provides a great benefit by providing a comfort level to the surgeon, regarding fluid and air leakage, which is comparable to that realized in standard open surgical procedures.
A particular advantage is realized in thorascopic surgery especially video-assisted thorascopic surgery (VATS). For example, spontaneous pneumothorax (collapsed lung) is extremely difficult to treat due to the aperture, surgical cut or resection lines in the lung which have caused the collapse.
Staples and/or sutures do not adequately seal air leak to reinflate the lung. Using standard, minimally invasive thorascopic procedures, the compromised lung is resealed using staples and/or sutures and the device of the present invention is utilized to apply fibrin sealant over the resection lines and staple lines. The ports used can be standard thorascopic ports of 10-16 mm and the application of sealant is preferably under direct thorascopic supervision (VATS). Thereafter, the lung can be reinflated.
