Devices and methods for cinching a side-delivered prosthetic heart valve for delivery and deployment in a native annulus

The side-deliverable transcatheter prosthetic heart valve system addresses deployment challenges by using an actuator to cinch and uncinch the valve frame, enabling secure seating and alignment within the native annulus while minimizing tissue contact, thus overcoming size and orientation issues in traditional delivery methods.

AI Technical Summary

Technical Problem

Traditional transcatheter prosthetic heart valves face challenges in delivery and deployment due to size constraints and orientation issues when trying to align with the native valve annulus, particularly with side-deliverable valves that require precise seating and avoidance of native tissue contact.

Method used

A side-deliverable transcatheter prosthetic heart valve system that includes a valve frame with a flow control component and an actuator attached to a proximal subannular anchoring element, allowing for cinching and uncinching to facilitate deployment and secure seating within the native annulus while minimizing contact with native tissue.

Benefits of technology

Enables the deployment of larger valves with improved alignment and secure seating in the native annulus, reducing the risk of incomplete seating and tissue damage, and allowing for the valve to be securely anchored without pushing the proximal subannular portion towards the atrium.

Abstract

A side-deliverable prosthetic valve includes a valve frame and a flow control component mounted within a central channel of the valve frame and configured to permit blood flow through the central channel in a direction along a central axis of the prosthetic valve. An actuator is removably attached to a proximal subannular anchoring element of the valve frame. A first portion of the actuator is removably attached to an interior surface of the valve frame in at least one location distal to the proximal subannular anchoring element. The first portion is configured to pull the proximal subannular anchoring element inwardly toward the central axis. A second portion of the actuator is removably attached, at least in part, to an exterior surface of the valve frame. The second portion is configured to pull the proximal subannular anchoring element outwardly away from the central axis.
