    Abstract: A transcatheter valve prosthesis includes a stent having a radially compressed configuration for delivery within a vasculature and an expanded configuration for deployment within a native heart valve. The stent includes an inflow portion, an outflow portion, and at least one commissure post extending between the inflow portion and the outflow portion. Inflow and/or outflow markers are positioned on the stent to enable longitudinal and rotational orientation of the stent during the installation at the implant location.

    Abstract: Methods for purging a balloon catheter of air. An inflation fluid is inserted into a balloon and an inflation lumen of a balloon catheter. The inflation lumen is in fluid communication with the balloon. The balloon catheter is positioned in an inverted orientation with a distal end thereof disposed below a proximal end thereof. The distal end of the balloon catheter includes a balloon. A vibration source is positioned in direct contact with an outer surface of the balloon catheter. The balloon catheter is vibrated via the vibration source. A vacuum is applied or pulled on the inflation lumen of the balloon catheter. The steps of vibrating the balloon catheter and applying the vacuum are performed simultaneously.

    Abstract: A transcatheter valve prosthesis includes a stent and a prosthetic valve. The prosthetic valve is configured to substantially block blood flow in one direction to regulate blood flow through a central lumen of the stent. 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 extending between the inflow portion and the outflow portion. Each axial frame member extends in an axial direction from a crown of the inflow portion to at least a crown of the outflow portion. Each axial frame member has a first end adjacent to the crown of the inflow portion, the first end having a reduced width relative to a width of a length of the axial frame member between the first end and the crown of the outflow portion.

    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.
