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: Systems, devices and methods of valvular prosthetics having one or more bioresorbable components are described. The bioresorbable components can resorb overtime, allowing the ingrowth of tissue in and around the valvular prosthetic.

Abstract: Apparatuses, systems, and methods for prosthetic valves. The prosthetic valves disclosed herein may be utilized for improved deployment, sealing, and anchoring to an implantation site. An implantation site may comprise a native heart valve or another implantation site in examples. Examples of prosthetic valves may include a proximal tensioning body positioned at a proximal portion of the prosthetic valve and a distal tensioning body positioned at a distal portion of the prosthetic valve. A sealing skirt may have a proximal end portion coupled to the proximal tensioning body and a distal end portion coupled to the distal tensioning body. The sealing skirt may be tensioned by the proximal tensioning body and the distal tensioning body and deflectable to conform to a shape of the native valve.

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.
