Abstract: Balloon catheters for delivery of prosthetic hear valves are provided. The balloon catheters are configured to deploy a prosthetic heart valve through inflation. The balloon catheters are further configured with one or more retention bumpers to reduce or prevent migration of the prosthetic heart valve during delivery. Balloon catheters described herein are configured with substantially incompressible retention bumpers that promote longitudinal inflation fluid flow.

Abstract: A dry valve crimping and loading system includes packaging, a crimper disposed in the packaging, and a dry valve prosthesis disposed within a crimper chamber of the crimper. The crimper chamber has a first volume in an expanded state a second volume in a collapsed state, wherein the first volume is greater than the second volume. The crimper is configured to transition the dry valve prosthesis from an uncompressed state to a compressed state when the crimper chamber transitions from the expanded state to the collapsed state to expel the glycerol from the dry valve prosthesis as the crimper transitions the dry valve prosthesis from the uncompressed state to the compressed state.
