Prosthetic heart valves may be delivered to a targeted native heart valve site via one or more delivery catheters. In some embodiments, the prosthetic heart valve includes structural features that securely anchor the prosthetic heart valve to the anatomy at the site of the native heart valve. Such structural features can provide robust migration resistance. In addition, the prosthetic heart valves can include structural features that improve sealing between the prosthetic valve and native valve anatomy to mitigate paravalvular leakage. In particular implementations, the prosthetic heart valves occupy a small delivery profile, thereby facilitating a smaller delivery catheter system for advancement to the heart. Some delivery catheter systems can include a curved inner catheter to facilitate deployment of the prosthetic heart valve to a native tricuspid valve site via a superior vena cava or inferior vena cava.

Prosthetic heart valves

Prosthetic heart valves may be delivered to a targeted native heart valve site via one or more delivery catheters. In some embodiments, the prosthetic heart valves are implanted using catheter-based deployment systems that include multiple control wires. In particular implementations, the deployment systems can include a retrieval catheter that can be used to recapture the prosthetic heart valve back into a delivery sheath after being expressed from the delivery sheath. The prosthetic heart valves can include a plurality of optional suture knots to enhance migration resistance. Some delivery catheter systems can include a controllably bendable control catheter and/or a deflectable catheter to facilitate deployment of the prosthetic heart valve to a native tricuspid valve site via a superior vena cava or inferior vena cava.

Some embodiments described herein include a heart valve replacement system that may be delivered to a targeted native heart valve site via one or more delivery catheters. In some embodiments, a prosthetic heart valve of the system includes structural features that securely anchor the prosthetic heart valve to the site of the native heart valve. Such structural features can provide robust migration resistance.

Some embodiments described herein include a heart valve replacement system that may be delivered to the targeted heart valve site via a delivery catheter. In some embodiments, the heart valve replacement system can assemble a valve device after the valve device is delivered to the heart. In some embodiments, heart valve replacement system includes two anterior flaps that are separate but overlap each other.

Transcatheter heart valve prosthesis assembled inside heart chambers or blood vessels

Prosthetic heart valves described herein can be deployed using a transcatheter delivery system and technique to interface and anchor in cooperation with the anatomical structures of a native heart valve. Some embodiments of prosthetic valves described herein include an anchor portion that couples to the anatomy near a native valve, and a valve portion that is mateable with the anchor portion. In some such embodiments, the anchor portion and/or the deployment system includes one or more prosthetic elements that temporarily augment or replace the sealing function of the native valve leaflets.

Systems and methods for heart valve therapy

Devices used to deploy transvascular medical device systems and methods for using such devices are described in this document. For example, this document describes dilating introducer devices used for the percutaneous vascular deployment of catheter-based medical devices such as structural heart medical devices. Such dilating introducer devices can facilitate the percutaneous vascular deployment of catheter-based medical devices without an additional introducer sheath.

Dilating introducer devices and methods for vascular access

This document provides devices and methods for the treatment of heart conditions. For example, this document provides prosthetic heart valves and transcatheter heart valve replacement methods. The prosthetic heart valves can be configured into a low-profile configuration for containment within a small diameter delivery sheath. The prosthetic heart valves include can include a valve member attached to a stent frame. In some embodiments, the valve member is a molded biomaterial with a novel shape and resulting performance characteristics. Localized protective covering members can be attached to the stent frame to prevent the valve member from contacting the stent frame as the valve member cycles between its open and closed configurations.

A replacement heart valve prosthesis for transcatheter repair of a native valve, the replacement heart valve comprises a valve construct mounted to the exterior surface of an expandable frame. The frame comprises an expandable region near the distal end of the frame, and a cusp region near the proximal region comprising a plurality of valve attachment features. The valve construct may be attached to the valve construct at least at the valve attachment features. The replacement heart valve prosthesis of present disclosure may be a more durable and long-lasting valve that has added benefits by placing valve tissue between the expandable frame and native cardiac tissue.
