Abstract: A leaflet resection device includes a first jaw, a second jaw pivotably connected to the first jaw, a first linkage assembly coupled to the first jaw, and a second linkage assembly coupled to the second jaw. The second linkage assembly includes a first resection blade and a second resection blade that are configured to cut a leaflet of a native heart valve or a previously implanted valve prosthesis along a curved path when the first and second linkage assemblies are actuated.

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.

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 valve leaflet resection device includes a catheter (110), an electrode assembly (140) slidably disposed within the catheter and deployable from the catheter and configured to remove a portion of a leaflet of a heart valve, a leaflet retainer (130) slidably disposed within the catheter and deployable from the catheter, the leaflet retainer configured to grasp a leaflet of a heart valve, and a capture basket (120) configured to capture a resected portion of the leaflet of the heart valve upon retraction of the leaflet retainer.

Abstract: A catheter includes a handle with torqueing and steering mechanisms. The torqueing mechanism includes a rotatable nosecone and a bearing coupled to the nosecone to be rotatable therewith. The bearing is concentrically disposed over a shaft of the catheter. The steering mechanism includes a rack coupled to the bearing to be slideable therewith and a pull wire having a proximal end attached to the bearing and a distal end attached to a distal portion of the shaft. Rotation of the nosecone causes an entire length of the shaft to rotate and axial movement of the rack tensions the pull wire to bend the distal portion of the shaft. A valve relief component is slidingly disposed over the shaft and is configured to dock onto the handle when not in use.
