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 transcatheter valve prosthesis includes a stent and a prosthetic valve. The stent includes an inflow portion, an outflow portion, and a transition portion extending between the inflow portion and the outflow portion. The transition portion includes a plurality of axial frame members, and three of the plurality of the axial frame members are commissure posts. At least two of the plurality of the axial frame members are commissure posts having a first end connected to a crown of the inflow portion and an unattached second end disposed within the outflow portion such that a pair of struts of the outflow portion intersect each commissure post at a mid-portion thereof. The prosthetic valve is configured to substantially block blood flow in one direction to regulate blood flow through a central lumen of the stent.

Abstract: A transcatheter valve prosthesis includes a balloon expandable stent and a prosthetic valve. An inflow portion of the stent includes a plurality of crowns and a plurality of struts with each crown being formed between a pair of opposing struts. Endmost inflow side openings and endmost inflow crowns are formed at the inflow end of the stent and the inflow end of the stent has a total of twelve endmost inflow crowns. An outflow portion of the stent includes a plurality of crowns and a plurality of struts with each crown being formed between a pair of opposing struts. Endmost outflow crowns are formed at the outflow end of the stent and the outflow end of the stent has a total of six endmost outflow crowns. The prosthetic valve is disposed within and secured to the stent.

Abstract: A crimper configured to radially compress a transcatheter valve prosthesis into a crimped configuration for delivery within a vasculature. The transcatheter valve prosthesis includes a frame and at least one leaflet secured within the frame. The crimper is configured to apply pressurized fluid to the at least one leaflet of the transcatheter valve prosthesis during the crimping process to prevent protrusion of the leaflet into the frame of the transcatheter valve prosthesis that may cause leaflet pinching and damage. The crimper includes a plurality of crimper elements that collectively define a crimper chamber of the crimper, and at least one crimper element of the plurality of crimper elements includes an integral channel extending therethrough for applying the pressurized fluid to the at least one leaflet.

Abstract: A leaflet folding accessory or tool configured for use with a crimper when radially compressing a transcatheter valve prosthesis into a crimped configuration for delivery within a vasculature. The crimping accessory is configured to apply or remove fluid to or from the at least one leaflet of the transcatheter valve prosthesis during the crimping process to prevent protrusion of the leaflets into the frame of the transcatheter valve prosthesis that may cause leaflet pinching and damage.
