Systems and methods for delivering and implanting heart valves are disclosed. The delivery systems can include an integrated introducer. The integrated introducer can include a sheath having an inner diameter that is smaller than the outer diameter of a delivery capsule of the delivery system and an outer diameter that is approximately equal to the outer diameter of the delivery capsule. The integrated introducer can include a hub having a hemostatic seal. The hub can have a locking mechanism configured to fix the integrated introducer in place on the delivery system.

Delivery system with inline sheath

A delivery system for percutaneously deploying a prosthetic heart valve. The system includes an inner shaft assembly, a delivery sheath capsule and a handle maintaining a first actuator and a second actuator. The capsule is configured to compressively retain the prosthetic heart valve over the inner shaft assembly. The first actuator is operated to proximally retract the delivery sheath capsule and expose the prosthetic heart valve relative to the capsule. The second actuator is operated to proximally retract the prosthetic heart valve by transmitting forces to the inner shaft assembly.

Transcatheter prosthetic heart valve delivery system with recapturing feature and method

A percutaneous stented valve delivery device including an inner shaft, a sheath, and a delivery capsule. The sheath slidably receives the inner shaft. A capsule proximal zone is attached to the sheath. A capsule distal zone is configured to transition between normal and flared states. A diameter of the distal zone is greater in the flared state, and the capsule includes a shape memory component that naturally assumes the normal state. The device is operable to perform a reversible partial deployment procedure in which a portion of the prosthesis is exposed distal the capsule and allowed to radially expand. Subsequently, with distal advancement of the capsule, the distal zone transitions to the flared state and imparts a collapsing force onto the prosthesis, causing the prosthesis to radially collapse and become recaptured within the delivery capsule. The capsule can include a laser cut tube encapsulated by a polymer.

Stented transcatheter prosthetic heart valve delivery system and method

An intravascular catheter such as a dilatation catheter for angioplasty procedures having a removable distal shaft section. The catheter construction allows the original distal shaft section of the catheter to be removed and a replacement distal shaft section to be secured to the proximal section which is useful with angioplasty catheters when the dimensions of the balloon on the original distal shaft section are inappropriate for dilating a particular stenotic region. Such catheter construction is also useful when there is a need to implant a stent into a dilated stenotic region to maintain its patency.
