Abstract: Balloon catheters for delivery of prosthetic hear valves is 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 balloon catheter configured for delivery of a prosthetic heart valve is provided. The balloon catheter is configured to deploy a prosthetic heart valve through inflation. The balloon catheter is provided with a reinforcing member configured to increase the rigidity of the balloon catheter over an operational portion of the device. The increased rigidity serves to prevent damage to an introducer sheath, patient anatomy, or the prosthetic heart valve during delivery of the prosthetic heart valve.
