Devices and methods for preparing a transcatheter heart valve system

摘要

Devices and methods for preparing a transcatheter heart valve system. The device includes a housing, sealing apparatuses and a port. The housing forms a chamber sized to receive a prosthetic valve and a portion of a delivery device. During use, the prosthesis is seated in the chamber, and the sealing apparatuses operated to seal the chamber about the delivery device. Air bubbles in a liquid delivered through the delivery device and to the chamber are removed from the system via the port, thereby flushing the system. Further, the device is manipulated to permit loading of the prosthesis into the delivery device in an air bubble-free environment.

主权项

1. An assembly for loading and delivering a stented prosthetic heart valve, the assembly comprising:
a delivery device including: a tube terminating at a distal end and defining a lumen, a shaft disposed within the lumen and connect to a tip, the tip located distal the distal end; and a valve loading device selectively connected to the delivery device, the valve loading device including: a housing forming a chamber and terminating at opposing, first and second ends, wherein an opening to the chamber is defined at each of the first and second ends, a first sealing apparatus associated with the first end and configured to selectively sealingly engage the tip, a second sealing apparatus associated with the second end and configured to selectively sealingly engage the tube, a port open to the chamber; wherein the assembly is configured to provide a flushing state in which a stented prosthetic heart valve is located within the chamber and the valve loading device is assembled to the delivery device such that air bubbles entrained in a liquid delivered to the chamber can be removed via the port.
