Publication number: 20150142021Abstract: A multiple-firing crimp device comprises crimps, a shaft, a crimp movement assembly, and a snare. Each crimp has an internal hollow. The shaft has a distal crimping location, an exterior surface, and an interior with the clips stacked therein, the crimps moving therein along a longitudinal axis. The shaft defines a lateral opening proximal to the crimping location and communicates the interior to the environment outside the exterior surface. The crimp movement assembly within the shaft delivers the first crimp to the distal crimping location by moving the first crimp longitudinally from a first proximal position into the distal crimping location and returning to a second proximal position without the first crimp. The snare pulls at least one cord from distal of the first crimp through the first crimp and through a portion of the shaft and out the side of the shaft through the lateral opening.Type: ApplicationFiled: November 17, 2014Publication date: May 21, 2015Inventors: Kevin W.

Publication number: 20140296962Abstract: A method for implanting a stent includes contracting a self-expanding/forcibly-expanding stent of a shape-memory material set to a given shape to a reduced implantation size with a delivery system having drive wires. The stent has a selectively adjustable assembly with adjustable elements operatively connected to the drive wires such that, when the adjustable elements are adjusted by the drive wires, a configuration change in at least a portion of the self-expanding stent occurs. The contracted stent is inserted into a native annulus in which the stent is to be implanted. The drive wires are rotated with the delivery system to forcibly expand the stent into the native annulus. While rotating the drive wires, a torque applied to the drive wires is determined with the delivery system. Rotation of the drive wires is stopped based upon a value of the determined torque.Type: ApplicationFiled: May 15, 2014Publication date: October 2, 2014Inventors: Richard Cartledge, Kevin W.
