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: The present disclosure relates to delivery devices for transcatheter stented prosthesis loading, delivery and implantation. The delivery devices provide a loaded delivery state in which the stented prosthesis is loaded and compressed over the delivery device. The compression of the stented prosthesis can be adjusted with one or more elongate tension members, which extend around the stented prosthesis and proximately to an actuation and release assembly that can be provided as part of a handle assembly. The delivery device can be manipulated to adjust tension in the tension members to permit the stented prosthesis to compress, self-expand, and ultimately release from the shaft assembly. In some embodiments, the tension in one or more tension members is adjusted with one or more actuation and release assemblies.

CPC classification number: A61F2/2436 , A61F2/966 , A61F2/9517
Abstract: Valve delivery catheter assemblies including components that limit trauma to the expanded prosthetic valve and body channels as the distal tip of the catheter is withdrawn through the expanded valve and thereafter from the body. Catheter assemblies according to the present invention can include a handle assembly, an introducer sheath, and a distal tip assembly. The handle assembly can include a fixed main handle and two or more rotating handles that allow a user to control the distal tip assembly of the catheter. A safety button can be included on the handle assembly to allow for precise and consistent positioning of the prosthetic valve in the body. A valve retaining mechanism can be included to assist in retaining the prosthetic valve prior to deployment.

IPC: A61F2/24
Abstract: A mechanism for adjusting the chordae connecting the leaflets of a mitral valve to the papillary muscles in order to restore normal functioning of the mitral valve. The devices or mechanisms can correct problems associated with both prolapsed leaflets and restricted leaflets to allow the leaflets to properly coapt, thereby preventing or minimizing regurgitation. In accordance with the invention, the mechanisms or devices used for adjusting the chordae can be delivered and implanted in a minimally invasive and/or percutaneous manner, such as via transapical methods, transfermoral methods, or trans-septal methods.
