Abstract: An apparatus includes a body assembly, a shaft defining a longitudinal axis extending from the body assembly, an acoustic waveguide having a flexible portion, and an articulation section coupled with the shaft. A portion of the articulation section encompasses the flexible portion of the waveguide. The articulation section has a first member and a second member translatable relative to the first member. An end effector has an ultrasonic blade that is in communication with the waveguide. An articulating control assembly has a motor. The motor is operable to translate the first and second members to thereby deflect the end effector away from the longitudinal axis at the articulation section.

Abstract: Devices and methods for occluding the left atrial appendage (LAA) to prevent blood from clotting within the LAA and subsequently embolizing, particularly in patients with atrial fibrillation. A foam implant encapsulated with a tough thromboresistent membrane is placed via transvascular means into the LAA and anchored with adhesives and/or mechanical anchors. Tissue over- and in-growth are optimized to anchor the implant in place and provide a permanent occlusion.

The articulation control assembly includes an articulation control member and a transmission assembly. The articulation control member is rotatably mounted relative to the shaft assembly. The transmission assembly is operatively connected between the articulation control member and the articulation section of the shaft assembly. The transmission assembly is configured to transmit selective manipulation of the articulation control member to the articulation section and selectively actuate the articulation section.

Abstract: Described are medical graft products, systems, and methods for treating fistulae. Certain products of the invention are configured to have portions residing in and around a primary fistula opening, e.g., one occurring in a wall of the alimentary canal. One such product includes a biocompatible graft body which is configured to block at least the primary opening. The graft body includes a capping member, which is configured to contact portions of the alimentary canal wall adjacent to the primary opening, and an elongate plug member extending from the capping member, which is configured to extend into at least a portion of the fistula. In certain embodiments, a graft body component has the capacity to expand or otherwise change form to provide a suitable capping arrangement. Such a component can include a resilient wire frame, e.g., one that is self-expandable or one that requires at least some manipulation in order to expand.

Abstract: Soft tissue repair grafts are described comprising an anti-adhesion layer, a structural layer, and a localization layer. These layers may be distinct or integrated into one substrate. The term layer is used to distinguish tissue repair graft functionality rather than distinct material layers. The distinct layers of functionality may comprise a single plane of a substance.

Abstract: A purse string suture instrument includes an end effector with first and second jaws disposed at a distal portion of an elongate tubular shaft. The first and second jaws are pivotably coupled to each other and to the elongate tubular shaft. The first and second jaws are spaced apart and define a gap therebetween. First and second pluralities of teeth extend perpendicularly from the first and second jaws respectively, and the first plurality of teeth is longitudinally offset from the second plurality of teeth. The first and second jaws are transitionable between open and approximated configurations. The approximated configuration is adapted to clamp tissue in the gap between the first and second jaws, thereby displacing sections of tissue outwardly between the first and second pluralities of teeth.

Abstract: A system and method for attaching tissue to bone are provided. In one embodiment, a system for attaching tissue to bone includes a suture, suture anchor, inserter tool, drill, and drill guide having an outer guide and an inner guide. A method for attaching tissue to bone includes attaching a suture to tissue, nesting the suture in a notch on the distal end of the outer guide, passing the suture through a lumen formed in the outer guide, and inserting an inner guide in a lumen formed in the outer guide. The drill guide protects the suture from rotational movement of the drill and allows a user to maintain alignment between the drill guide and the drilled hole. As a result, a suture anchor can be more easily positioned within the drilled hole.
