摘要： An apparatus for suturing deep puncture wounds utilizes a capturing member which is pivotally mounted to the distal end of an elongate rod. During use, the capturing member is inserted into a body cavity through a trocar sheath positioned in a wound and pivoted into a position in which it extends beneath the tissue surrounding the wound. A membrane or other suture-capturing surface is formed on the surface of the capturing member. A suture to be applied to the wound has anchors on each of its ends, and suture-carrying needles carry each of the suture ends and their corresponding anchors. The suture-carrying needles are individually passed through the tissue layers surrounding the wound and subsequently passed through the membrane of the capturing member. The suture ends and corresponding anchor means are released from the needles. The capturing means is pivoted to position in which it extends longitudinally of the elongate rod, causing the anchors to become engaged by the membrane by virtue of their inability to pass through the membrane unless carried by a needle. A lifting force is applied to the elongate rod to lift the capturing member out of the wound, pulling the ends of the suture out of the wound to close the opening in the tissue.

摘要： An apparatus for tissue dissection and instrument anchoring, including a dissection balloon having a viewing window (preferably a rigid, transparent window) at its distal end, or including an anchoring or dissection balloon having nonuniform elasticity selected to achieve desired inflated shape and pressure characteristics, and methods for using such apparatus. The window, which can be a lens (such as a wide angle lens), is transparent and either rigid or non-rigid but sufficiently strong to retain a desired optical shape while (and after) being pushed against tissue layers by a rigid instrument deployed within the balloon. In preferred embodiments, the balloon is a long-necked dissection balloon deployed through a cannula. In other embodiments, the invention is a dissection balloon having a viewing window at its distal end, or an anchoring or dissection balloon having nonuniform elasticity selected to achieve desired inflated shape and pressure characteristics, for use in an apparatus for tissue dissection, tissue retraction, and instrument anchoring. In other embodiments, the invention is a dissection balloon assembly including a long-necked dissection balloon having a viewing window at its distal end, and a housing to which the dissection balloon's mouth is attached. In accordance with the method of the invention, the distal end of a long-necked dissection balloon (deployed through a cannula) is inserted between tissue layers and inflated to dissect the tissue layers. The dissection balloon has a window at its distal end, or nonuniform elasticity selected to achieve desired inflated shape and pressure characteristics, or both such a window and such nonuniform elasticity.

摘要： A method and apparatus for creating a surgical work space by lifting the abdominal wall and retracting abdominal organs during surgery utilizes a lifting body having two or more retraction rods supported by the lifting body. The rods are designed to be introduced into the abdominal cavity through a laparoscopic puncture opening and to be extended within the abdominal cavity to provide a lifting area. In the preferred embodiment, a pair of retraction rods disposed with the bores and substantially parallel to each other are inserted into the abdominal cavity through an incision in the abdominal wall. The retraction rods are spread apart from each other while their parallel orientation is maintained. The lifting body is connected to a lifting arm and lifted, causing the retraction rods to lift and support the abdominal wall.

摘要： An improved trocar is provided which includes converters for adapting to different size surgical instruments while maintaining sealing. The invention also includes an improved trocar tube body seal design which accepts and accommodates surgical tool angulation while still maintaining sealing. Still further, the invention provides a trocar obturator with a snap-fit joint which permits the forward portion of the obturator to be detached from the trocar body and separately used with the trocar tube subassembly. With this option, a latch mechanism is configured opposite to a converter to retain the obturator fixed with the trocar tube subassembly.

摘要： A system for locally stabilizing an anastomotic site of a vessel of a beating heart during a surgical procedure is disclosed. The system includes bonding a pad to the myocardium and attaching a control arm to the pad, all by use of a bioabsorbable adhesive. The control arm is grasped and manipulated by a retractor thereby stabilizing the anastomotic area during the surgical procedure. The pad is optional and can be ommitted in one embodiment where the control arm has feet that are directly bonded to tissue. The pad may also have barbs or can include suction cups. The pad can include a helix-shaped fastener or a mechanical fastener that can be easily linked or hooked to a surgical instrument for manipulation.

摘要： A retractor and a surgical tool are positioned within a cannula, and a dissection cradle of the retractor is positioned at the distal end of the cannula. The retractor includes a first portion with an axis approximately parallel to the axis of the cannula and a second portion with an axis skewed relative to the axis of the cannula. The dissection cradle is located at the distal end of the second portion of the retractor, and may include two substantially parallel, spaced legs with the retractor shaped in a loop between and in a plane skewed relative to the axes of the legs, and with the loop directed away from the surgical tool. Thus, in operation, when the surgeon locates a vessel and side branch of interest, the surgeon extends the retractor to cradle the vessel in the dissection cradle. Once cradled, the retractor may be fully extended to urge the vessel away from the axis of the cannula to isolate the side branch for exposure to the surgical tool. The dissection cradle may include a forward shoulder for positioning a suture loop. A forwardly-projecting tensioner supports a length of suture from the loop to maintain the loop in tension for transport along the vein. During advancement, the suture loop is safely maintained in place due to the tension provided by the tension mount and the support provided by the shoulder. Upon reaching the surgical site of interest, the retractor is retracted, causing the suture loop to be displaced onto the vein at the desired position. In one embodiment, the loop is tightened by pulling on the length of suture near the proximal end of the cannula to constrict the suture loop about the vein near the distal end of the cannula.
