Abstract
A delivery device for a collapsible prosthetic heart valve includes a support shaft around which a compartment is defined, an inner shaft 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 therethrough, and a distal sheath 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 may provide flow communication between the lumen of the inner shaft and the compartment.

A delivery device for a collapsible prosthetic heart valve, the delivery device comprising:
- a support shaft around which a compartment is defined, the compartment being adapted to receive the valve in an assembled condition;
- an inner shaft 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 therethrough;
- a distal sheath operatively connected at a distal end to the inner shaft and slidable therewith, the distal sheath being adapted to selectively cover and uncover the compartment and the valve;
- and
- a first flow path providing flow communication between the lumen of the inner shaft and the compartment.
A delivery system for a collapsible prosthetic heart valve, the delivery system comprising:
- a support shaft around which a compartment is defined, the compartment being adapted to receive the valve in an assembled condition;
- an inner shaft 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 therethrough in flow communication with an exterior of the delivery device;
- a distal sheath operatively connected at a distal end to the inner shaft and slidable therewith, the distal sheath being adapted to selectively cover and uncover the compartment and the valve;
- a first flow path providing flow communication between the lumen of the inner shaft and the compartment;
- and
- a removable plug adapted for connection to the delivery device to occlude the flow communication between the lumen of the inner shaft and the exterior of the delivery device.
A method of flushing a delivery device for a collapsible prosthetic heart valve, the method comprising:
- providing a delivery device including a support shaft around which a compartment is defined, an inner shaft extending through the support shaft and adapted to slide relative to the support shaft along a longitudinal axis thereof, and a distal sheath having a distal end operatively connected to the inner shaft and a proximal end, the distal sheath being slidable with the inner shaft;
- mounting a collapsible prosthetic heart valve in the compartment;
- sliding the distal sheath to cover the compartment and the valve;
- and
- flushing a liquid through the compartment from a distal end of the compartment to a proximal end of the compartment.
