Delivery cylinder for prosthetic implant

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.

Telescoping prosthetic valve with retention element

An implantable device is disclosed. The device includes a leaflet frame subcomponent and an anchor frame subcomponent that are configured to be delivered in a series configuration and subsequently nested or telescoped in-situ.

Prosthetic mitral valves and their methods of manufacture and use.

IMPLANT RELEASE SYSTEM

A medical device release system may include an elongated rod having an enlarged distal end, a ring element slidingly disposed over the elongated rod, and two or more pins. The ring element may have a center channel sized and shaped to receive the elongated rod, wherein the enlarged distal end of the rod is larger than an inner diameter of the center channel, preventing the ring element from disengaging from the distal end of the rod. The two or more pins may each have a proximal end attached to the ring element and a distal end extending longitudinally and radially away from the ring element, the distal ends configured for releasable connection to a medical device.

CONTAINMENT VESSEL WITH IMPLANT SHEATHING GUIDE

A containment vessel for storing and rinsing a medical implant coupled to a delivery system having an outer sheath may include a hollow element having a wall, a proximal end, a distal end, and a lumen extending between the proximal end and the distal end, the lumen of the hollow element being configured and adapted to contain a medical implant in a partially-deployed configuration during storage and rinsing of the medical implant and a proximal end cap including a secondary proximal end cap removably secured to the proximal end cap and configured to reversibly seal the proximal end cap to the outer sheath, thereby establishing a closed fluid connection between the lumen of the hollow element and a lumen of the outer sheath. The proximal end cap may include a sheathing guide configured and adapted to direct the medical implant into the lumen of the outer sheath.

CLAMPS FOR COUPLING EXPANSION AND LOCKING ASSEMBLIES TO FRAMES OF PROSTHETIC VALVES

The present disclosure relates to implantable, mechanically expandable prosthetic devices, such as prosthetic heart valves, and to devices and methods for coupling expansion and locking assemblies to frames of such prosthetic devices.

SYSTEMS AND METHODS FOR MANUFACTURING A STENT FRAME
20220354673 · 2022-11-10 · ·

A prosthetic heart includes a support structure, an actuator member, a plurality of leaflets, and a sealing material. The support structure includes a plurality of struts movably coupled together such that the support structure moves incrementally between a radially compressed state and a radially expanded state. The struts include a plurality of commissure struts. The actuator member is coupled to the struts of the support structure and is configured to incrementally move the support structure between the radially compressed state and the radially expanded state and to automatically lock the support structure in a particular state. The leaflets are coupled to the commissure struts of the support structure and configured to allow unidirectional blood flow through the prosthetic heart valve. The sealing material is coupled to the support structure and includes a plurality of commissure extensions that wrap around and are coupled to the commissure struts of the support structure.

Methods and devices for delivery of a prosthetic valve

A valve prosthesis and a system for delivering a valve prosthesis are described herein. The system can include a support frame, a valve anchor comprising an anchoring leg and a plurality of U-shaped members, and a suture coupled to the support frame and slidably coupled to the anchoring leg.

Prosthetic heart valve holder apparatus

Apparatus for use with a prosthetic heart valve includes a holder, to which the heart valve is releasably attached, and an elongated handle. The handle can be connected to the holder simply by pushing a distal end of the handle straight into a recess in the holder. After this has been done, the holder preferably releasable latches onto the handle, and the handle can also be rotated about its longitudinal axis to transmit torque to the holder (e.g., a rotatable portion of the holder). Rotation of such a rotatable portion of the holder can be used to deflect portions of the valve radially inward. This operation of a rotatable portion of the holder is preferably one-way only. The handle can be released from the holder at any time, and it can similarly be reconnected to the holder at any time.

Fully-Transseptal Apical Pad with Pulley for Tensioning
20220054258 · 2022-02-24 · ·

An apical pad for securing a prosthetic heart valve within a native valve annulus. The apical pad includes a first collar, a second collar and plurality of struts extending between the first collar and the second collar. The plurality of struts has a delivery condition in which the plurality of struts collectively form a first cross-section and a deployed condition in which the plurality of struts collectively form a second cross-section greater than the first cross-section. The apical pad may be coupled to a tether extending from a prosthetic heart valve and may transition from the delivery condition to the deployed condition by tensioning the tether.
