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 having an initial delivery configuration configured for delivery within a vasculature to a treatment site, the 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 the treatment site, anda cinch mechanism including at least one suture surrounding a second portion of the heart valve prosthesis and configured to hold the second portion of the heart valve prosthesis in a reduced diameter state for delivery to the treatment site, wherein the second portion of the heart valve prosthesis is held in the reduced diameter state solely by the cinch mechanism when the delivery catheter is in the initial delivery configuration,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 the initial 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, the delivery catheter having an initial delivery configuration configured for delivery within a vasculature to a treatment site, the delivery catheter 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 including at least one suture 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, wherein the heart valve prosthesis is held in the reduced diameter state solely by the cinch mechanism along the distal segment of the second tubular shaft when the delivery catheter is in the initial delivery configuration. - 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 configured to hold a first portion of the heart valve prosthesis in a reduced diameter state and a cinch mechanism configured to hold a second portion of the heart valve prosthesis in a reduced diameter state, the cinch mechanism including at least one suture, 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 an initial delivery configuration; advancing the delivery catheter in the initial delivery configuration through a vasculature with the first portion of the heart valve prosthesis held in the reduced diameter state by the capsule segment and the second portion of the heart valve prosthesis held in the reduced diameter state by the cinch mechanism until the heart valve prosthesis is positioned at a native heart valve, wherein the second portion of the heart valve prosthesis is held in the reduced diameter state solely by the cinch mechanism during the step of advancing the delivery catheter through the vasculature; longitudinally repositioning the capsule segment to permit the first portion of the heart valve prosthesis to return to an expanded state; and releasing the cinch mechanism to permit the second portion of the heart valve prosthesis to return to an expanded state. - View Dependent Claims (18, 19, 20)
