Aspects of the disclosure relate to 'wet' transcatheter prosthetic heart valve or other implant packaging and assemblies in which a prosthetic heart valve or other implant is loaded into a first portion of a delivery device and positioned within a container in which sterilizing fluid is retained to sterilize interior portions of the container as well as provide moisture to prevent the implant from drying out. The disclosure also relates to methods of sterilizing the disclosed assemblies. Some disclosed methods include at least two sterilizing steps and adjustment of a mechanical seal member or formation of multiple seals so that areas proximate the seals are also sterilized during the sterilization process.

Assemblies for sterilizing a wet stored prosthetic heart valve

Embodiments hereof relate to a delivery system for a transcatheter valve prosthesis, the delivery system having an integral centering mechanism to circumferentially center both the delivery system and the valve prosthesis within a vessel at the target implantation site. The centering mechanism may include expandable wings that may be selectively aligned with openings formed through a sidewall of an outer shaft of the delivery system, a coiled wing that may be selectively exposed through an opening formed through a sidewall of an outer shaft of the delivery system, a plurality of elongated filaments extending through a plurality of lumens of an outermost shaft of the delivery system that may be selectively deployed or expanded, an outer shaft that includes at least one pre-formed deflection segment formed thereon, a tool having a deployable lever arm, and/or a plurality of loops deployable via simultaneous longitudinal and rotational movement.

Delivery system having an integral centering mechanism for positioning a valve prosthesis in situ

The disclosure relates to transcatheter stented prosthesis delivery devices including a handle assembly connected to a shaft assembly on which a stented prosthesis is loaded and compressively retained with a plurality of elongate tension members. The delivery devices include a cutting assembly that can sever the elongate tension members after the stented prosthesis is expanded at a target site so that the delivery device can be withdrawn from the patient. Certain embodiments position the cutting assembly at least within the shaft assembly and others position the cutting assembly over the shaft assembly. Various disclosed cutting assemblies are actuated with the handle assembly or the like, which draw the tension members across the blade or vice versa.

Transcatheter prosthetic heart valve delivery system with distal cutting assembly

A 'dry' packaging in which a prosthetic heart valve is packaged within a container with hydrogel that can be provided in many forms. Certain embodiments include hydrogel that is preloaded with glycerol or the like. The hydrogel regulates the humidity within the container through a diffusion-driven mechanism if a gradient of humidity between the inside and the outside of the hydrogel exists. Humidity regulation is important to prevent the tissue of the valve structure from drying out. When the partially-hydrated hydrogel is present within container, which is saturated with air of a predefined humidity, the water molecules from the air will be absorbed by the hydrogel if the air humidity is high (i.e. when the thermodynamics favor hydrogel hydration) or vice versa. Various embodiments are configured to also house at least a portion of a delivery device for delivering the prosthetic heart valve.

Packaging for dry tissue prosthetic heart valve

Embodiments hereof relate to methods of delivering a valve prosthesis to an annulus of a native valve of a heart, the native valve having chordae tendineae. A chordae management catheter is positioned within a ventricle of the heart, the chordae management catheter having a displacement component at a distal end thereof. The displacement component has an annular shape and defines a central lumen therethrough. The displacement component is radially expanded to push chordae tendineae within the ventricle radially outward. A valve delivery system is introduced into the ventricle of the heart via a ventricular wall of the heart. The valve delivery system has the valve prosthesis at a distal portion thereof. The valve delivery system is advanced through the central lumen of the radially expanded displacement component towards the annulus of the native valve of the heart. The valve prosthesis is deployed into apposition with the annulus of the native valve.

Assemblies and methods of sterilizing a wet stored prosthetic heart valve

Methods of transcatheter delivery of a prosthetic heart valve. A distal region of a guide member assembly is advanced into a heart of a patient. The distal region is docked to native anatomy of the heart. A delivery device, including a collapsed prosthetic heart valve, is advanced over the docked guide member assembly. The collapsed prosthetic heart valve is located at an implantation site. The prosthetic heart valve is deployed from the delivery device, and then the delivery device is removed from the patient. At least a portion of the guide member assembly is removed from the patient. In some embodiments, the docking structure is docked to one or more of native mitral valve leaflets, chordae in the left ventricle, or walls of the left ventricle as part of a transseptal mitral valve delivery procedure.

Prosthetic heart valve delivery systems and methods

The invention features modular implantable ventricular assist devices configured to be, at least in part, assembled within a patient. The devices generally include a pump assembly and an expandable frame. The frame is configured to engage tissue of a patient when implanted. The pump assembly is configured to be operably coupled to the frame when the frame is implanted and in the expanded configuration.
