摘要： Disclosed herein are embodiments of methods of using 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.
