Systems, devices and methods for removing a blood clot () from a blood vessel (). Various uses of suction pressure and positive pressure, proximal and/or distal to the blood clot () assist with clot dislodgement and removal. The pressure(s) may be constant and/or cycled/pulsed to assist with clot dislodgement and/or removal. Various further devices assist with separating the clot () from the vessel ().

Devices, systems and methods to remove blood clots

Various systems, devices and methods associated with the placement of a dock or anchor for a prosthetic valve. The anchor can comprise a plurality of coils adapted to support a valve prosthesis, the plurality of coils including an upper coil, one or more middle coils, and a lower coil. The upper coil can have a larger diameter than the one or more middle coils and the lower coil, and the upper coil is configured to engage a wall of an atrium of the heart at a position superior to and spaced axially from the mitral valve annulus after the plurality of coils have been fully delivered from the coil guide catheter.

Valve docking devices, systems and methods

A method of operating a counterpulsation device (CPD) in a human or animal subject is disclosed, the method including: receiving a heart beat signal indicative of the heart beat of the subject; providing counterpulsation therapy by controlling the pressure supplied to a CPD drive line in pneumatic communication with the CPD to cause the CPD to alternately fill with blood and eject blood with a timing that is determined at least in part based on the heart beat signal; while providing counterpulsation therapy, receiving a CPD drive line pressure signal indicative of the pressure in the CPD drive line; and adjusting the pressure supplied to the drive line based at least in part on the drive line pressure signal.

Counterpulsation device driver apparatus, method and system

Anchors and systems for docking a prosthetic heart valve at a native heart valve are disclosed. An anchor can include at least three coils and a covering extending over at least a portion of the at least three coils. The covering comprises a fabric material and a foam underneath the fabric material.

Apparatus and methods for implanting a replacement heart valve

An anchor for a prosthetic heart valve includes a core, a first cover layer, and a second cover layer. The core includes a plurality of helical turns. One or more outflow turns of the plurality of helical turns has a diameter configured to be disposed on an outflow side of a native valve, and one or more inflow turns of the plurality of helical turns has a diameter configured to be disposed on an inflow side of a native valve. The first cover layer is disposed over and contacts the helical core, and the first cover layer includes a first material. The second cover layer is disposed over and contacts the first cover layer, and the second cover layer includes a second material, which is different than the first material.

Coiled anchor for supporting prosthetic heart valve, prosthetic heart valve, and deployment device

Prosthetic heart valves and anchors for use with such valves are provided that allow for an improved implantation procedure. In various embodiments, an anchoring device is formed as a coiled or twisted anchor that includes one or more turns that twist or curve around a central axis. One or more arms attached to the frame of the valve guide the anchoring device into position at the native valve as it exits the delivery catheter, and the expandable prosthetic valve is held within the coil of the anchoring device. The anchoring device and the valve can be delivered together, simplifying the valve replacement procedure.

Devices, systems and methods for delivering a prosthetic mitral valve and anchoring device

Devices, systems and methods to image blood clots

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.

Mitral repair and replacement devices and methods

Anchors and systems for docking a prosthetic heart valve at a native heart valve are disclosed. An anchor can include at least three coils and a seal positioned between at least two adjacent coils of the at least three coils. The seal circumscribes at least a portion of the at least two adjacent coils and has opposite ends that are spaced away from corresponding opposite ends of the at least three coils.

Systems, devices and methods for securing tissue including the annulus of a mitral valve. The systems, devices and methods may employ catheter based techniques and devices to plicate tissue and perform an annuloplasty.

Tissue anchors, systems and methods, and devices

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.

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.
