Abstract: An implantable prosthetic device has a coaptation element and at least one anchor. The coaptation element is configured to be positioned within the native heart valve orifice to help fill a space where the native valve is regurgitant and form a more effective seal. The coaptation element can have a structure that is impervious to blood. The coaptation element can be connected to leaflets of the native valve by the anchor.

Abstract: A coronary artery check valve includes a stent configured to attach to an inner wall of a coronary artery of a living subject, and a tapered helical coil coupled to the stent and configured to regulate blood flow in the coronary artery. The coronary artery check valve is configured to prevent retrograde flow of the coronary blood supply during diastole by closing during systole of the heart when the tapered helical coil compresses longitudinally, and opening when the tapered helical coil expands longitudinally to permit blood flow into the coronary artery when a coronary pressure of the living subject drops below diastolic blood pressure.

Abstract: An exemplary recapturable valve repair system for repairing a native valve of a patient during a non-open heart procedure has a delivery device, a valve repair device, and a tethering line. The delivery device has a catheter and a coupler. The valve repair device is configured to be delivered through the catheter and attach to a native valve of a patient. The valve repair device includes a coaption element, a proximal collar, and first and second paddles. The first and second paddles are connected to the coaption element. The coupler is releasably connected to the proximal collar. The tethering line connects the valve repair device to the delivery device for recapturing the valve repair device.

Abstract: The present disclosure provides embodiments of a method for improving coaptation of the anterior and posterior mitral valve leaflets by applying a remodeling force to the posterior leaflet. In particular embodiments, a tension member is secured at a location on or proximate to the posterior leaflet. Tension can be applied to the tension member in a direction superiorly and anteriorly toward the interatrial septum. The tension member can be secured at a location proximate the septum to maintain the tension. The tension provides the remodeling force, pulling the posterior leaflet superiorly and anteriorly to improve coaptation with the anterior leaflet.

Abstract: An implantable device or implant is configured to be positioned within a native heart valve to allow the native heart valve to form a more effective seal. In some implementations, the implantable device or implant, or one or more portions thereof, can be configured to expand and/or contract. For example, the implantable device or implant can narrow during delivery and expand on implantation on the native heart valve.
