DELIVERY SYSTEM HAVING A SHORT CAPSULE SEGMENT AND A CINCH MECHANISM AND METHODS OF USE THEREOF
First Claim
1. A delivery system for delivering a heart valve prosthesis comprising:
- a heart valve prosthesis; and
a delivery catheter including,a capsule segment configured to encircle a first portion of the heart valve prosthesis and to thereby hold the first portion of the heart valve prosthesis in a reduced diameter state for delivery to a treatment site, anda cinch mechanism surrounding a second portion of the heart valve prosthesis and configured to hold the remainder of the heart valve prosthesis in a reduced diameter state for delivery to the treatment site,wherein the capsule segment and the cinch mechanism are disposed longitudinally adjacent to each other and do not overlap when the delivery catheter is in a delivery configuration.

Abstract
A delivery system including a heart valve prosthesis and a delivery catheter. The delivery catheter includes an outer shaft component, an inner shaft component and a cinch mechanism. The outer shaft component has a capsule segment configured to encircle a first portion of the heart valve prosthesis and to thereby hold the first portion of the heart valve prosthesis in a reduced diameter state for delivery to a treatment site. The cinch mechanism surrounds a second portion of the heart valve prosthesis and is configured to hold the remainder of the heart valve prosthesis in a reduced diameter state for delivery to the treatment site. The capsule segment ends proximal of the cinch mechanism when the delivery catheter is in a delivery configuration. The capsule segment and the cinch mechanism in tandem hold the heart valve prosthesis in the reduced diameter state.

11. A delivery catheter for a heart valve prosthesis comprising:
-
a first tubular shaft with a capsule segment; and a second tubular shaft having a proximal segment positioned within the first tubular shaft and a distal segment disposed distal of the capsule segment of the first tubular shaft; and a cinch mechanism disposed about the distal segment of the second tubular shaft, wherein the capsule segment and the cinch mechanism are configured in tandem to hold a heart valve prosthesis in a reduced diameter state. - View Dependent Claims (12, 13, 14, 15, 16)

17. A method of deploying a heart valve prosthesis comprising:
-
loading a heart valve prosthesis onto a delivery catheter, wherein the delivery catheter includes a capsule segment and a cinch mechanism that are configured in tandem to hold the heart valve prosthesis in a reduced diameter state, wherein the capsule segment and the cinch mechanism are disposed longitudinally adjacent to each other and do not overlap when the delivery catheter is in a delivery configuration; positioning the delivery catheter with the heart valve prosthesis in the reduced diameter state at a native heart valve; longitudinally repositioning the capsule segment to permit a first portion of the heart valve prosthesis to return to an expanded state; and releasing the cinch mechanism to permit a second portion of the heart valve prosthesis to return to an expanded state. - View Dependent Claims (18, 19, 20)
