A kit for delivering microwave ablative energy to tissue and methods for using the kit are included. The kit includes an access catheter, an implant deployment tool, and a microwave delivery device. The implant deployment tool is configured to be inserted into the access cathether and has an implant disposed therein in a contracted state and being slidable out of a distal opening and expandable into an expanded state. The microwave delivery device is configured to deliver the microwave ablative energy to the tissue and to be advanced through the access catheter and slidably disposable within the implant when the implant is in the expanded state.

The present invention is a replacement mitral valve suitable for catheter-based deployment. The replacement mitral valve has structure and dimensions that are uniquely suited to engage the annulus surrounding the native mitral valve and to restore normal function to a diseased valve. The invention describes the structures and functions of a replacement mitral valve and methods that are adapted for minimally invasive, catheter-based deployment of the valve.

A hernia repair device, comprising: an inflatable balloon having an inflation tube, the inflation tube having a proximal end attached to said balloon and a distal end adapted to be extracted from the body, separately from the balloon, via an opening which is smaller than a laparoscopic opening, and a mesh removably attached to said balloon, wherein the inflation tube passes through the mesh.

The present technology is generally directed to shunting systems, including shunting systems having a shapeable/conformable elongated housing or shunting element that can be contoured or otherwise selectively shaped to improve a fit with patient anatomy. The shunting systems and elongated housings described herein can have numerous other advantageous features expected to improve the operation of shunting systems, such as beveled leading edges, lateral outlets, suture rings, positioning appendages, and the like.

A prosthetic delivery system may include a plurality of concentric shafts and an actuator mechanism for actuating one or more of the concentric shafts. A stop mechanism may be coupled to the actuator mechanism. The stop mechanism prevents advancement or retraction of at least some of the shafts beyond a predetermined position unless the stop mechanism is released. A second stop mechanism may be included in the system for controlling another of the shafts. A plurality of filaments may be coupled to a prosthesis carried by the delivery system and actuation of the filaments may be used to control deployment or retrieval of the prosthesis.

The present invention relates to a radially collapsible frame (1) for a prosthetic valve, the frame (1) comprising an outflow end region (3) at a proximal end of the frame (1) and an inflow end region (2) at a distal end of the frame (1), opposite to the outflow end region (3). The frame (1) further includes at least two radially spaced commissure attachment regions (10, 10, 10) and a cell structure (30), composed of a plurality of lattice cells being arranged radially around a flow axis of the frame (1) and connecting the at least two commissure attachment regions (10, 10, 10). Finally, at least one anchoring/positioning arch (20, 20, 20) is provided, wherein said at least one anchoring/positioning arch (20, 20, 20) radially overlaps the cell structure (30) at least partially. In order to form the inventive frame from as a single piece, the invention further relates to a method comprising bending the at least one anchoring/positioning arch (20, 20, 20) towards the cell structure (30) of the frame (1).

Methods for controlling properties of structural elements of implantable medical devices, where the structural elements contain shape memory alloys (SMAs) include promoting or inhibiting in vivo formation of R-phase crystal structure or converging or separating the R-phase from the austenite phase.

In one embodiment, the present disclosure is a fixation device including a median zone, a first fixation zone including a base region extending from the median zone and an end region distant from the median zone, and including an expandable region in between the base region and the end region, the expandable region adapted to move between a closed position and an expanded position, wherein the first fixation zone is adapted to be positioned within a bone hole and, with the expandable region in the expanded position, the expandable region is positioned against bone surrounding the bone hole, and a second fixation zone including a base region extending from the median zone at a position different from the base region of the first fixation zone and an end region distant from the median zone.

The medical device has an element including two discs, small (5) and large (6), joined by a central part (7), the structure of the element being determined by a nitinol core (8) with sufficient flexibility to be folded over itself and inserted in a flexible instrument (9) suitable for incorporation in an endoscope or similar device. Also included is a layer (10) of soft material, such as polyurethane, silicone or another polymer that covers the core (8). The core (8) is filamentous and forms at least the two discs (5, 6) via spokes (81) and the central part (7) via a rod (82). The instrument (9) includes a capsule (11) in which the device (1) that is folded over itself is accommodated, and a catheter (12) that can be connected to the capsule (11), with a pushing mechanism (14) for expelling the device (1) from the capsule (11) in a controlled manner
