Abstract: In general, arthroscopic medical implements and assemblies and methods of operating arthroscopic medical implements and assemblies are provided. Devices, systems, and methods are described herein in connection with accessing a surgical site using an arthroscopic medical implement. In an exemplary implementation, an optical sensor of the arthroscopic medical implement can gather and output image data, and an inertial sensor of the arthroscopic medical implement can gather and output orientation data. The orientation data can be used to modify the gathered optical image to maintain a display of the gathered optical image in a predetermined desired orientation before, during, and after any rotation of the arthroscopic medical implement. The arthroscopic medical implement can also include at least one sensor configured to gather and output pressure and/or temperature.

Abstract: Various methods and devices for performing arthroscopic surgery are provided. In particular, methods and devices are provided for reshaping, unclogging, and vibrating tubing of an aspiration pump in a fluid management system. For example, a fluid management system is provided that includes a valve assembly disposed on a housing and configured to selectively pinch closed tubing disposed within a first pathway and a second pathway. The valve assembly is configured to bias tubing disposed within the first and second pathways to an open position after the tubing is pinched closed by the valve assembly. As another example, a fluid management system is provided that includes a vibratory mechanism coupled to a valve and configured to vibrate the valve so as to facilitate the flow of debris through tubing disposed within first and second tubing pathways.

The barb includes a yieldable element adapted to yield in response to a force, above a predetermined limit, tending to cause migration of the implant. The barb may comprise a shape memory material adapted to change shape when the material undergoes a stress induced phase change and thereby to disengage from the lumen wall.

In the crimped diameter the at least one region of the first section and the at least one region of the second section are immediately adjacent one another.

Abstract: A graft system for intraluminal delivery in a vessel in need of repair comprising a graft, anchoring means, and a strippable sheath around at least part of the graft. A preferred anchoring means is a balloon-expandable stent. Also included in the invention is a method of using the device to treat a body lumen. The strippable sheath is removable by pulling on a drawstring to remove it which permits expansion of the graft. The positioning of the device may then be adjusted prior to stent dilation. A preferred embodiment of the invention includes a bifurcated graft system for intraluminal delivery in an aortic aneurysm comprising a bifurcated graft having a distal region and two legs, an expandable stent disposed in part of the distal region, and a strippable crocheted sheath around the distal region and one of the two legs. The strippable crocheted sheath is removable by untying it to permit expansion of the graft after initial placement within the aneurysm.

Abstract: A method of making a non-porous tubular graft is disclosed. The method includes the step of securing a plurality of fastening elements extending through an outer layer of knitted, woven, or braided material along a length of the outer layer, wherein the fastening elements extend outwardly from the outer layer. The method further includes the steps of placing an inner layer of non-porous material within the outer layer such that an underside of each fastening element is positioned between the inner layer and the outer layer and laminating the outer layer to the inner layer to form the non-porous tubular graft.

Abstract: Tissue ablation probes, systems, and methods are provided for treating tissue (e.g., a tumor). The probe comprises an inner probe shaft, and an outer probe shaft disposed around the inner probe shaft. The outer probe shaft has a distal portion fixably mounted to the inner probe shaft, and a proximal portion rotatably mounted to the inner probe shaft. The probe further comprises a coiled ablation electrode disposed between the proximal portion and the distal portion. The electrode is configured for unwinding when the proximal portion rotates about the inner probe shaft in one direction, thereby placing the electrode in a radially expanded geometry, and configured for winding when the proximal portion rotates about the inner probe shaft in another opposite direction, thereby placing the electrode in a radially collapsed geometry.
