Abstract: A method for treating a heart valve involves delivering a catheter into a ventricle of a heart, advancing a coil from the catheter, rotating the coil at least partially around a papillary muscle of the ventricle, embedding a distal end of the coil in tissue of the ventricle, and manipulating a suture coupled to the coil to adjust a position of the papillary muscle.

Abstract: A crimping system for a prosthetic heart valve comprises a split funnel comprising an elongated annular body having an enlarged insertion end, a narrower outlet end, and a central opening extending along a central longitudinal axis of the split funnel, between the insertion end and the outlet end. The body comprises first and second slots extending axially along opposite sides of the body from the outlet end toward the insertion end, the first and second slots defining first and second split portions of the body extending circumferentially between the first and second slots on opposite sides of the central opening. The crimping device is configured to crimp a prosthetic heart valve moving axially through the central opening from the insertion end to the outlet end while allowing portions of the prosthetic heart valve to protrude through the first and second slots and remain in an expanded configuration.

Abstract: Methods and devices for increasing flow in the left atrial appendage (LAA) include a conduit directing blood flow from a pulmonary artery into the LAA and/or a conduit drawing blood from the LAA by a Bernoulli effect. In one embodiment, a method comprises implanting a conduit in a pulmonary vein, expanding an inlet portion such that the conduit becomes anchored within the vein and directs blood through an outlet portion of the conduit into or toward the left atrial appendage.

Abstract: This disclosure pertains generally to prosthetic devices and related methods for helping to seal native heart valves and prevent or reduce regurgitation therethrough, as well as devices and related methods for implanting such prosthetic devices. In some cases, a spacer having a single anchor can be implanted within a native heart valve. In some cases, a spacer having dual anchors can be implanted within a native heart valve. In some cases, devices can be used to extend the effective length of a native heart valve leaflet.

Abstract: A prosthetic heart valve for implantation within a native atrioventricular heart valve. The prosthetic heart valve includes a self-expanding frame having an annular main body and a valve member disposed within the main body. The prosthetic heart valve includes an atrial sealing member formed by a fabric cover and a plurality of arms that are arranged side-by-side in a circumferential direction around the main body. The atrial sealing member extends radially outwardly from the main body and a peripheral portion of the atrial sealing member curves upwardly for conforming to surrounding native anatomy. The prosthetic heart valve further includes one or more ventricular anchors extending from the main body for capturing native leaflet tissue and thereby securing the prosthetic heart valve within the native atrioventricular heart valve.

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.
