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: Apparatuses, systems, and methods for prosthetic valves. Embodiments of prosthetic valves may include sealing bodies configured for an anchor to at least partially pass through. The pass through may allow for the sealing body to seal to a portion of a patient's heart in the event of a miscapture of a leaflet by the anchor. Embodiments may include modular valve systems and prosthetic valves including anchors for coupling to chordae, trabeculae, or papillary structures of a patient's heart. Embodiments may include prosthetic valves including anchors for engaging calcification of a patient's native valve.

Abstract: Devices, systems, and methods relate to implants, such as prosthetic valves for replacing native heart valves. Delivery systems for delivering the implants to an implantation site are also disclosed herein. A prosthetic valve may include a valve body supporting a plurality of prosthetic valve leaflets and one or more adjustable anchors coupled to the valve body for anchoring the prosthetic valve to leaflets of a native heart valve, wherein at least one of the adjustable anchors is axially slidable relative to the valve body for conforming to the native anatomy of the native heart valve.

Abstract: Valvular regurgitation is addressed by implanting devices at or near a native valve to treat leaflet issues. This can be done by treating the leaflets and/or by treating one or more natural chordae tendineae (chords). Treating the leaflets can include methods and devices that bring different leaflets together, and/or inhibiting or arresting a leaflet from billowing and/or flailing into the atrium. Treating the chords can include methods and devices that shorten chords, that increase tension in the chords, that attach chords to the ventricle wall or to each other, and the like. In each of the disclosed methods and devices, coaptation is increased and/or valvular regurgitation is reduced. The disclosed devices and methods can be performed on a beating heart.

Abstract: Devices, systems and methods are described herein to provide improved steerability for delivering a prosthesis to a body location, for example, for delivering a replacement mitral valve to a native mitral valve location. The steerable delivery system can contain a steerable rail configured for multi-plane bending to direct a distal end of the delivery system.

Abstract: Apparatuses, systems, and methods for prosthetic valves. Examples of prosthetic valves may be configured to anchor to an interior surface of a heart valve. Such prosthetic valves, in examples, may include a single frame that supports a plurality of prosthetic valve leaflets. In examples, multiple frames may be utilized to anchor to a heart valve and one or more of the frames may support a plurality of prosthetic valve leaflets.

Abstract: Traditional CABG procedures are performed by accessing the chest cavity and stopping the heart. However, off-pump CABG is becoming more wide-spread in use. Transcatheter CABG procedures are particularly advantageous and thus may become prevalent. A transcatheter CABG procedure can advantageously reduce complications, procedure time, and recovery time as well as providing benefits of being an off-pump, beating heart procedure. Accordingly, disclosed herein are several mechanisms and methods for accessing, implant anchoring, and visualization during a transcatheter CABG procedure.

Abstract: A delivery system includes a suture attachment mechanism for maintaining a connection to a heart valve after initial deployment, thereby allowing recapture of the heart valve if desired. A plurality of suture portions is provided along a distal end portion of the delivery system, each suture portion having a first end fixed to the delivery system and a second end releasably coupled to a retention member on the delivery system. A knob on a handle of the delivery system is actuated for causing the second end of each suture portion to be released from its respective retention member, thereby allowing the suture portions to be decoupled from the heart valve. The suture portions are located only along a distal end portion of the delivery system for improving reliability and consistency.
