Abstract: A delivery apparatus for a medical device can include a handle, a shaft, a plurality of sleeves, and a suture. The shaft includes a proximal end portion coupled to the handle and is configured to be disposed outside of a patient's body during an implantation procedure and a distal end portion configured to be disposed inside a patient's body during the implantation procedure. Each of the sleeves includes a connection portion coupled to the distal end portion of the shaft and a receiving portion configured to receive an apex of a stent or a prosthetic heart valve. The suture extends through the shaft and the sleeves and is configured for releasably securing the stent or the prosthetic heart valve to the receiving portions of the sleeves.

Abstract: A method for delivering a prosthetic valve to a native annulus of a heart can include inserting a delivery apparatus into a patient's body, advancing the delivery apparatus to an implantation location within the native annulus, retracting a delivery sheath of the delivery apparatus relative to the prosthetic valve to expose the prosthetic valve from a distal end of the delivery sheath, and after the prosthetic valve is exposed from the delivery sheath, expanding the prosthetic valve from a radially compressed state to a radially expanded state by reducing axial tension on a first end and a second end of the prosthetic valve.

Abstract: A delivery cylinder for a prosthetic implant can include a first tubular portion and a second tubular portion. The second tubular portion has a plurality of strut members coupled to the first tubular portion that define a volume for containing the prosthetic implant in a radially compressed state. The strut members can include respective flex regions configured such that application of force to the strut members causes deformation of the flex regions and corresponding radially inward or outward movement of the strut members relative to a longitudinal axis of the delivery cylinder between an expanded configuration and a contracted configuration.

Abstract: A loader and method for loading a transcatheter heart valve into a delivery sheath or catheter is described that is also configured to facilitate retrieval of the heart valve back through the delivery sheath while protecting the delivery sheath from damage. Another loader provides for easier crimping and loading of a THV into a delivery sheath or catheter from a storage jar or container. A method for crimping a THV facilitates easier end user preparation of the valve for implantation and reduces the likelihood of tissue deformation in the valve during storage. These devices and methods for deploying THVs simplify the valve replacement procedure.

Abstract: A method for retrieving a previously inserted prosthetic valve is disclosed. In one example, a loader assembly is inserted through a hub of a delivery sheath device. The delivery sheath device includes an expandable sheath that extends into a blood vessel of a patient. The loader assembly is advanced in a distal direction until a distal section of the loader assembly extends into the expandable sheath which is attached to a distal end of the hub. The distal section has a larger inner diameter than a middle tube section of the loader assembly. A delivery catheter is retracted to move a prosthetic valve attached thereto in a proximal direction until the prosthetic valve is received within the distal section. The loader assembly and the delivery catheter are removed from a proximal end of the hub while the prosthetic valve is retained within the distal section.

Abstract: A medical device for creating elongated incisions within a pericardium is provided. The device also includes an incision device operably coupled to a distal end of a catheter. The device also includes a retractable cutting apparatus disposed within an incision channel of the incision device. The retractable cutting apparatus includes a gear-actuated blade structured to move between a retracted and a deployed position. In an instance in which the gear-actuated blade is in the retracted position, the gear-actuated blade is disposed within the incision channel. In an instance in which the gear-actuated blade is in the deployed position, the gear-actuated blade at least partially protrudes from the incision channel. The retractable cutting apparatus also includes a torsion gear mechanism attached to the gear-actuated blade. The retractable cutting apparatus also includes a rotatable gear actuator that is structured to move the torsion gear mechanism.
