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, is transparent and either rigid or non-rigid but sufficiently strong to retain a desired optical shape while 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 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 use, the distal end of a long-necked dissection balloon is inserted between tissue layers and inflated to dissect the tissue layers.

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： 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： A disposable seal assembly for use with a reusable cannula preferably includes a flapper valve fluid seal and at least one instrument seal. The instrument seal has a sacrificial flange and a sealing flange that protrude from an inner baffle connected to the assembly's main body by a flexible outer baffle, and at least one elastomeric rib extending between the inner baffle and the body to prevent inversion of the inner baffle. Preferably, a surface of the sacrificial flange is configured to prevent the flanges from sticking together during use. An adaptor, tethered to the assembly's main body, has a central channel with an hourglass profile, a concave distal flange, distal bumpers for preventing the adaptor from translating too far into the main body, and a grip portion shaped to allow a user conveniently to separate the adaptor from the main body. Other aspects include systems with a reusable cannula, and methods for using such systems.

摘要： An assembly of cannula and endoscope and dissection tip facilitate surgical procedures at remote surgical site in tissue of a patient. Relative rotation of the cannula about the endoscope from clamped rotational fixation of the cannula and endoscope is made possible by flexing a resilient clamping segment, and such relative rotation promotes convenient positioning of an eccentric tissue-dissecting tip about a vessel being harvested from within tissue of a patient. Color tinting of the tip or color-tinted illumination of tissue at a remote surgical site enhances contrasting visualization through the tip via the endoscope among the tissue types encountered at the surgical site within a patient. A tool bridge or lateral support mounts to a more rigid component such as an endoscope that extends from the proximal end of a cannula to support a more flexible surgical instrument also extending from the proximal end of the cannula.

摘要： Devices, tools and methods for occluding fluid flow between two walls of tissue in a patient. Two walls of tissue are compressed together with sufficient compressive force to prevent fluid flow between the two walls, while ensuring that the compressive force is not so great as to cause tissue necrosis. The devices, tools and methods may be carried out using minimally invasive surgical techniques, such as in reduced-access surgical sites. Devices, tools and methods are provided for occluding an atrial appendix.
