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. L'invention concerne des cathéters à ballonnet pour l'administration de valvules cardiaques prothétiques. Les cathéters à ballonnet sont conçus pour déployer une valvule cardiaque prothétique par gonflage. Les cathéters à ballonnet sont en outre configurés avec un ou plusieurs tampons de retenue pour réduire ou empêcher la migration de la valvule cardiaque prothétique pendant l'administration. Les cathéters à ballonnet selon l'invention sont configurés avec des tampons de retenue sensiblement incompressibles qui favorisent l'écoulement de fluide de gonflage longitudinal.
