摘要： A system and method for restoring (e.g., replacing) a defective heart valve of a patient. A delivery system is manipulated to percutaneously deliver and implant a stented prosthetic heart valve to a native heart valve. A post-dilatation balloon is percutaneously delivered to the implantation site, and a compliant segment thereof is arranged within a region of the implanted prosthesis. The balloon is inflated such that the compliant segment expands and contacts the prosthesis, expanding a remodeling region of the prosthesis to a remodeled state. With these and related techniques, remodeling of an implanted, stented prosthetic heart valve to better match the native valve shape is possible, providing many benefits such as reducing the risk of paravalvular leaks.

摘要： 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.

摘要： Modular component mounting systems and methods employ a plurality of members adapted to be interlocked with one another and anchored to an instrument housing. Each of the members comprises a central elongated body, cross-holes extending transversely through the body, beads extending along corners of the body to a position spaced apart from an end of the body defining a key at the end of the body, a channel defined by a surface of the body and a pair of the beads to receive and register with a key of another member, and a fastener receptive orifice defined in the end of the body. A fastener extends though one of the cross-holes of a first member to be received by an end orifice of a second member, interlocking the members and preventing torsional movement by the members relative to one another.
