Abstract: Devices, systems and methods are described herein to provide improved treatment of a tricuspid valve. Such treatment may include tricuspid valve replacement, which may include providing a prosthetic tricuspid valve within the tricuspid valve annulus. Delivery systems for delivering the prosthetic tricuspid valve to the tricuspid valve annulus are disclosed herein. Treatment may also include repair of the tricuspid valve.

Abstract: Systems, apparatuses, and methods disclosed herein are provided for a motorized implant delivery system. The delivery system may utilize a processor for control of at least one motor for actuating a delivery apparatus. The delivery system may include sensors configured sense one or more of a condition of the patient's body or a condition of the delivery apparatus. The processor may process the signals provided by the sensors, which may comprise feedback signals to the processor.

Abstract: Devices and methods for securing a tissue anchor in tissue of a patient, in particular to ensure proper deployment of a cardiac tissue anchor by regulating the force or pressure of a deployment tool against the tissue. One way to ensure proper deployment force is to visualize the distal end of the tissue anchoring catheter from outside the body using a display for an imaging sensor, where the distal end of the catheter changes configuration when it is pressed against the tissue. Another method involves automatically regulating the pressure applied to the tissue prior to deployment of the tissue anchor, which may also be used in conjunction with visualization. Several safety locks to prevent deployment of the tissue anchor prior to establishment of the proper pressure are disclosed, which again may be used with visualization and/or an automated pressure regulator.

Abstract: A system including a delivery apparatus, a crimping device, and a loading assembly. The crimping device includes a housing disposed over a distal end portion of the delivery apparatus for receiving a radially expandable and compressible prosthetic heart valve. The housing includes a funnel segment, a pusher member, and an actuator releasably coupled to the pusher member. Movement of the actuator causes the pusher member to advance the prosthetic heart valve through the funnel segment for radially compressing at least a portion of the prosthetic heart valve. Compression of the prosthetic heart valve facilitates secure attachment of the prosthetic heart valve to the delivery apparatus. The loading assembly can include an additional funnel member for fully crimping and loading the prosthetic heart valve into the delivery apparatus for advancement through a patient's vasculature.

Abstract: A prosthetic valve includes an expandable valve frame and leaflets supported therein. A plurality of elongate anchor arms extends from an outlet end portion of the valve frame. Each elongate anchor arm includes anchoring protrusions, such as barbs, for engaging surrounding tissue. During delivery to the treatment site, the anchoring protrusions face inwardly. When released from the delivery catheter, the anchoring arms evert such that the anchoring protrusions reverse orientation and face outwardly. In this position, the protrusions can engage surrounding tissue and thereby secure the prosthetic valve within a native heart valve.

Abstract: A prosthetic heart valve delivery system having one or more features which facilitate access to a target annulus and improve maneuverability. The system may have a flexible access sheath having an inner lumen and a proximal handle attached to an elongated flexible catheter extending distally therefrom and having an outer diameter sized to fit through the access sheath. An expandable prosthetic heart valve is crimped and positioned in an inner lumen and near the distal end of the delivery catheter. A distal tapered nose cone attaches to the delivery catheter and facilitates passage through the patient's vasculature. An inner tube extends from the proximal handle through the delivery catheter inner lumen, through the prosthetic heart valve, and attaches to the nose cone. Finally, the system has a guidewire that extends through the proximal handle along the delivery catheter and projects distally from the nose cone. The system is especially useful for transfemoral atrioventricular valve replacements.

Abstract: Disclosed herein are embodiments of stabilizers for use in delivering a replacement heart valve. The stabilizers can receive a portion of a delivery system, such as a handle, to prevent unwanted motion of the delivery system. The stabilizer can include a linear actuator for adjusting a position of the delivery system once held within the stabilizer.
