Abstract: Transcatheter aortic valve prostheses for improving the cardiac function of a patient suffering from coronary artery disease. Transcatheter aortic valve prostheses include a valve component and a frame. The valve component includes valve leaflets and a skirt. The frame includes access cells that improve access to a patient's coronary arteries if further intervention is required and/or includes a window or conduction protection cell that is oriented to align with a portion of conduction system of the heart in situ to reduce conduction disturbances of the anatomy. Suture patterns for attaching a commissure to a commissure post of the frame, and for attaching a tissue bumper to the commissure post, are also described.

Abstract: A delivery system for prosthetic heart valves are provided. The delivery system includes a flexible shaft, a distal sheath capsule configured to contain the prosthetic heart valve, an inner steerable catheter including an inner distal flex component, and an outer steerable catheter including an outer distal flex component. The inner distal flex component includes a first cut pattern and a second cut pattern distal to the first cut pattern. The outer distal flex component includes a third cut pattern. The inner steerable catheter is rotatable at least 90 degrees relative to the outer steerable catheter when the third cut pattern of the outer distal flex component is disposed over at least a portion of the first cut pattern of the inner distal flex component and each of the inner steerable catheter and the outer steerable catheter is in the flexed configuration.
