  • Patent number: 5769862
    Abstract: A tube knot applicator for use in endosurgical procedures. The tube knot applicator has an elongated tube member having a distal end and a proximal end, as well as an axial passage therethrough. The tube member has slits for partially collapsing the distal end of the tube as well as a removable plug mounted in the distal end of the tube to prevent the distal end of the tube from collapsing by supporting the distal slitted end. A suture having at least one slip knot and at least one locking knot is mounted in the tube knot applicator with the knot tied about the collapsing distal end of the tube. A sleeve is mounted to the distal end of the tube knot applicator over the suture knot and the distal end.

  • Patent number: 5681324
    Abstract: A surgical tissue retrieval instrument has a collapsible pouch at the distal end of an elongated support tube for retrieving internal body tissue through a trocar tube. The instrument includes a belt which is formed into a loop slidably attached about the open end of the pouch. The belt is slidably extendable through the support tube for expanding the open end of the pouch to receive the tissue and retractable into the support tube for drawing the open end of the pouch closed to enclose the tissue in the pouch. The belt has an oblong, e.g., rectangular, cross section oriented with its larger cross-sectional dimension perpendicular to the plane of the loop to provide stability at the open end of the pouch and to enable use of the pouch in a scoop-like manner to place the tissue therein. A portion of the belt is thermally set into a curved configuration to urge the loop into a normally expanded shape with the belt extended from the distal end of the support tube.

  • Patent number: 5562684
    Abstract: A surgical knot pusher device comprises a thick-walled cannula or tube having a beveled elliptical face and a central channel for slidably receiving one end of a suture. The other end of the suture is slidably inserted in one of a pair of longitudinal grooves formed on the outer surface of the cannula which intersect the elliptical face at the opposite ends of its major axis. One of the longitudinal grooves extends along the longest portion of the cannula and the other longitudinal groove extends along the shortest portion of the of the cannula. As the knot pusher device is inserted into a surgical port, a knot formed in the suture is engaged by the beveled face and advanced toward a surgical site. A notch is formed at the proximal end of the cannula for receiving the end of the suture threaded into the central channel. A threading element comprising an elongated rod with a deformable loop is provided to thread the suture into the central channel of the cannula.

  • Patent number: 5397332
    Abstract: An applicator for applying a sheet of surgical material, e.g., a surgical mesh, to internal body tissue includes a delivery tube, a deployment tube slidably received within the delivery tube, and a shaft or irrigation tube slidably received within the deployment tube. An expandable spreader tip is connected between the distal ends of the shaft and the deployment tube. The spreader tip is collapsed and inserted in the delivery tube with the surgical mesh. The applicator is inserted through a trocar tube into a body cavity and the spreader tip is exposed by retracting the delivery tube relative to the deployment tube and shaft. The applicator has a first actuator for urging the spreader tip and surgical mesh into engagement with the tissue as the deployment tube is retracted and a second actuator for advancing the deployment tube relative to the shaft to expand the spreader tip to apply the surgical mesh to the tissue.

  • Patent number: 5284485
    Abstract: An improved endoscopic device of the type having a surgical needle; a hollow tube; and a filamentary strand attached at its distal end to the surgical needle, and slideably engaged at its proximal end about the tube with a partially tightened slip knot. The improvement in the device relates to means for pulling the filamentary strand through the hollow tube proximally when the surgical needle is detached from the strand. The device can be used to approximate tissue or ligate a vessel.

  • Patent number: 5282809
    Abstract: A suturing device for placing a continuous suture line between anchor knots is disclosed. The device has a cannula and first and second sutures. Each suture has a slide end, a distal loop, and a slip knot securing the distal loop to the slide end. The sutures are threaded through the cannula. One of the sutures has a stay end extending from the slip knot, and a needle attached to this stay end. The device is particularly adapted to place a continuous suture line during endoscopic surgical procedures.

  • Patent number: 5279539
    Abstract: A medical device is disclosed for enclosing an internal bodily organ or tissue during surgery. The device is a surgical pouch with two drawstrings. The first drawstring is made up of a resilient, wire-like thread for keeping the mouth of the pouch open during use, and is detachable from the pouch. The second drawstring is intended to cinch the mouth of the pouch closed after the organ or tissue is enclosed and the first drawstring is detached. It is composed of a compliant, bioabsorbable thread.A method of reducing or preventing post-operative ovarian adhesions is also disclosed. The method involves placing a bioabsorbable surgical pouch, especially the surgical pouch of this invention, over an ovary after a surgical procedure, and then cinching the mouth of the pouch closed to isolate the ovary from surrounding bodily tissue.
