AI Technical Summary
Existing prosthetic heart valves, particularly self-expanding ones, face challenges in precise and controlled deployment due to their outward biasing force causing them to 'jump' out of the delivery sheath, and may not anchor sufficiently to non-stenotic native valves, requiring additional anchoring devices that can complicate future interventions.
A delivery apparatus with a rotatable second shaft and a sheath retaining ring mechanism that allows controlled axial movement of the delivery sheath, coupled with a valve-retaining mechanism to secure the prosthetic valve, enabling precise deployment and anchoring to the native valve site without extending into non-diseased areas.
Enables precise and controlled deployment of prosthetic heart valves, minimizing trauma and simplifying future interventions by ensuring adequate anchoring to the native valve without unnecessary extension into healthy tissue.
