The mounting portion also includes an opening longitudinally extending therethrough and communicable with the instrument channel and sized for receiving an endoscopic instrument therethrough.

Abstract: The present invention is directed to an apparatus and its method of use in delivering surgical tissue connectors into an area of the body and removing the surgical tissue connectors from the body area. Svlore specifically, the present invention is directed to a surgical tissue connector apparatus having at least two tissue connectors connected by a length of cord and a delivery and removal tube. At least one of the tissue connectors has a base with a tapered, beveled or chamfered surface projecting from one end of the base. A hook or other type of tissue connector projects from the opposite side of the base. The hook is positioned on the base where a peripheral side surface of the base shields the hook from unintentionally snagging objects. The base peripheral surface is also dimensioned to slide easily through an interior bore of the tube. This enables the base and the projecting hook to be easily delivered through the tube into an area of the body.

Abstract: The present invention generally relates to devices and systems that utilize an inflatable bladder for generating, cutting, capturing, and/or transplanting one or more skin blisters. In some aspects, methods and devices in accordance with the present teachings can enable the harvesting of skin grafts from an increased variety of potential donor sites, such as areas of the body having uneven surfaces or a smaller radius of curvature (e.g., the arm) or large area donor sites where the creation of a vacuum may require a high power negative pressure source. In various aspects, systems, devices, and methods in accordance with the present teachings can also enable the efficient transplant of the grafts directly from the skin graft harvester to the recipient site without the transfer of the grafts generated by the harvester to another substrate prior to transplantation.

Abstract: The present disclosure includes a knotless suture anchoring system for anchoring a suture with respect to a body cavity, including a bone anchor body with at least one rigid anchoring structure to secure the anchor body within the body cavity. The anchor body has a longitudinal bore and cross-pin extending across the bore. A retention member is coupled to the anchor body with a break notch therebetween, which may selectively fracture to separate the body from the retention member. Additionally there is a suture cutout on the retention member and a relief feature positioned along the break notch and approximately diametrically opposed from the suture cutout, the relief feature acting to alter the force dissipation along the break notch during the separation of the retention member from the anchor body.
