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 catheter based balloon enabled prosthetic heart valve delivery device is provided. The balloon enabled delivery device is configured to deploy a prosthetic heart valve through inflation. The balloon enabled delivery device is further configured to reduce or prevent migration of the prosthetic heart valve during deployment. Migration is prevented through a combination of balanced inflation of the balloon, inflation fluid flow balancing structures, retention rings, retention covers, and balloon surface treatments.
