PROBLEM TO BE SOLVED: To provide a device, system, and method for transcatheter delivery of a collapsible prosthetic heart valve.SOLUTION: A delivery device 10 for a collapsible prosthetic heart valve 6 includes: a support shaft 21 around which a compartment 23 is defined; an inner shaft 26 extending through the support shaft and adapted to slide relative to the support shaft along a longitudinal axis thereof, the inner shaft having a lumen 25 therethrough; and a distal sheath 24 operatively connected at a distal end to the inner shaft and slidable therewith. The compartment may receive the valve in an assembled condition, and may be selectively covered and uncovered by the distal sheath. A first flow path C may provide flow communication between the lumen of the inner shaft and the compartment.SELECTED DRAWING: Figure 1 |
