Abstract:

Delivery systems, methods and associated devices to facilitate delivery and deployment of a heart implant. Such delivery systems and methods of delivery include use of a pair of magnetic catheters, including an anchor delivery catheter carrying an anchor, which can be stacked with or can be axially offset from the magnetic head. Such systems further include use of a puncturing guidewire advanceable through the magnetic head of the anchor delivery catheter to establish access to a chamber of a heart and which is attached to a bridging element such that continued advancement of the guidewire draws a bridging element attached to the first anchor across the chamber of the heart while the bridging element remains covered by the magnetically coupled catheters. Methods and devices herein also allow for cutting and removal of a bridge element of a deployed heart implant.

A61B 18/14

Abstract:

A system configured to detach an interventional implant from a cardiac valve includes a guide catheter and a capture mechanism routable through the guide catheter. The capture mechanism comprises a capture hypotube with a container portion/space configured to receive an interventional implant connected to cardiac valve tissue. The capture mechanism also includes a cutting arm axially moveable relative to the capture hypotube. The capture hypotube and the cutting arm each include cutting elements that are brought together upon actuation of the cutting arm to thereby cut the cardiac valve tissue surrounding the interventional implant to free the implant from the cardiac valve.

A61B 17/128

Abstract:

A device configured to cut leaflet tissue at a cardiac valve may comprise a guide catheter having a proximal end and a distal end, the guide catheter being positionable at a cardiac valve. The device may further include a cutting mechanism routable through the guide catheter and configured to extend from the distal end of the guide catheter, the cutting mechanism configured to cut a portion of leaflet tissue of the cardiac valve. Finally, the device may comprise a handle coupled to the proximal end of the guide catheter, the handle comprising at least one control operatively connected to the cutting mechanism such that the at least one control is configured to provide selective actuation of the cutting mechanism.
