Abstract: Apparatus for treating blood flow regurgitation through a native heart valve includes a selective occlusion device sized and configured to be implanted in the native heart valve and selectively operating with at least one of the first or second native leaflets to allow blood flow through the native heart valve when the heart cycle is in diastole and reduce blood flow regurgitation through the native heart valve when the heart cycle is in systole. A clip structure is coupled with the selective occlusion device. The clip structure is configured to be affixed to a margin of at least one of the first or second native leaflets to secure the selective occlusion device to the native heart valve.

Abstract: Disclosed are various configurations of electrodes with accompanying extensions and wires configured to be attached at or near the left atrium of a heart to allow the device to be held snug against the endocardium and out of the blood flow for low energy defibrillation of the atria in response to atrial fibrillation or other atrial arrhythmias. The portion of the lead internal to the atrium (e.g., the left atrium) is restrained against the endocardium of the left atrium by way of a restraint mechanism. In one example, the electrode is configured to attach to the atrial septum, with wires containing memory-shaped metal to keep the wires against the heart wall. In yet another example, the electrode is configured to be part of a mitral valve device.

Abstract: Systems and methods described herein include a pressure delivery component that has a pressure applicator configured to selectively apply therapeutic pressure to a treatment portion of a user body, and also includes a thermal delivery component that has a thermal applicator that is a configured to apply thermal treatment to the treatment portion. The thermal applicator may be removably disposable in operative relationship with the pressure delivery component in a use configuration of the treatment delivery component such that the thermal applicator is disposable between the treatment portion and the pressure applicator when the treatment delivery component is disposed on the treatment portion in the use configuration. Moreover, the pressure applicator is operable to apply pressure to the thermal applicator to enhance apposition of the thermal applicator to the treatment portion.

Abstract: A coiled anchor is positioned at a mitral valve by extending and deflecting a catheter such that a distal end portion of the catheter has a curved shape that is disposed in a left atrium and a distal end of the catheter is positioned near a commissure of the mitral valve. A ventricular portion of the coiled anchor is advanced from the catheter under the mitral valve at the commissure and into a left ventricle. An atrial portion of the coiled anchor is deployed in the left atrium by retracting the catheter off the atrial portion of the coiled anchor while maintaining the position of the ventricular portion of the coiled anchor in the left ventricle.

Abstract: An implant and method for repairing and/or replacing functionality of a native mitral valve are in various embodiments configured to reduce or eliminate mitral regurgitation and residual mitral valve leakage. A coiled anchor can be used to implant a prosthetic valve in a native mitral valve of a heart. The coiled anchor can include a plurality of ventricular turns and one or more atrial turns. The coiled anchor is configured to be implanted at the native mitral valve with the plurality of ventricular turns positioned in a left ventricle of the heart and around valve leaflets of the native mitral valve. The plurality of ventricular turns are configured such that when a radially outward pressure is applied to at least one of the plurality of ventricular turns, the coiled anchor is biased such that a first diameter of a first turn of the plurality of ventricular turns is expanded and a second diameter of a second turn of the plurality of ventricular turns is reduced.

Abstract: An implant and method for repairing and/or replacing functionality of a native mitral valve are in various embodiments configured to reduce or eliminate mitral regurgitation and residual mitral valve leakage. A coiled anchor can be used to implant a prosthetic valve in a native mitral valve of a heart. The coiled anchor can include a first turn, a second turn, and a third turn. The coiled anchor is configured to be implanted at the native mitral valve with the second turn and the third turn positioned in a left ventricle of the heart and around the valve leaflets of the native mitral valve. The first turn is positioned in a left atrium of the heart such that the first turn is spaced apart from the native mitral valve. The coiled anchor is configured for positioning such that the first turn is the sole turn of the coiled anchor positioned in the left atrium.

Abstract: Apparatus for treating blood flow regurgitation through a native heart valve (16) includes a selective occlusion device sized and configured to be implanted in the native heart valve (16) and selectively operating with at least one of the first or second native leaflets (16a, 16b) to allow blood flow through the native heart valve (16) when the heart cycle is in diastole and reduce blood flow regurgitation through the native heart valve (16) when the heart cycle is in systole. A clip structure (50) is coupled with the selective occlusion device. The clip structure (50) is configured to be affixed to a margin of at least one of the first or second native leaflets (16a, 16b) to secure the selective occlusion device to the native heart valve (16).

Abstract: Various systems, devices and methods associated with the placement of a dock or anchor (72) for a prosthetic valve (120). The anchor (72) may take the form of a helical anchor having multiple coils (104, 108) and/or a stent-like structure. Various methods include different levels of minimal invasive procedures for delivering the prosthetic valve anchor (72) and prosthetic valve (120), as well as tissue anchors for plication or other purposes to the native valve position in the heart (14).

Abstract: Methods for replacing a native heart valve. An anchor comprises coils adapted to support a heart valve prosthesis. The anchor is positioned at a native heart valve. An expansible heart valve prosthesis is delivered into the anchor and expanded inside the coils. This moves at least one coil from a first diameter to a second, larger diameter while securing the anchor and the heart valve prosthesis relative to each other. The heart valve prosthesis comprises a seal on the expansible heart valve prosthesis. Additional apparatus and methods are disclosed.
