Abstract
A delivery assembly for percutaneously delivering a transcatheter heart valve prosthesis into a vasculature of a patient includes a capsule and a spindle. The capsule is configured to constrain the transcatheter heart valve prosthesis therein. The spindle includes a spindle body coupled to a shaft disposed within the capsule, and a dampening arm having a first end and a second end. The first being of the dampening arm is coupled to the spindle body and the second end of the dampening arm is configured to extend between an interior surface of a frame and a leaflet of the transcatheter heart valve prosthesis to minimize leaflet protrusion through cells of a frame of the transcatheter heart valve prosthesis.
Claims21
A delivery assembly for percutaneously delivering a transcatheter heart valve prosthesis into a vasculature of a patient, the delivery assembly comprising:
- a capsule configured to constrain the transcatheter heart valve prosthesis therein;
- and
- a spindle including:
- a spindle body coupled to a shaft disposed within the capsule;
- and
- a dampening arm having a first end and a second end, the first end being coupled to the spindle body and the second end of the dampening arm being configured to extend between an interior surface of a frame and a leaflet of the transcatheter heart valve prosthesis to minimize leaflet protrusion through cells of the frame of the transcatheter heart valve prosthesis.
A method of loading a transcatheter heart valve prosthesis into a capsule of a delivery device, the method comprising:
- disposing a distal end of a dampening arm of a spindle between a leaflet of the transcatheter heart valve prosthesis and a frame of the transcatheter heart valve prosthesis;
- and
- radially compressing the transcatheter heart valve prosthesis within the capsule of the delivery device.
