Abstract: Devices, systems and methods are provided for stabilizing and grasping tissues such as valve leaflets, assessing the grasp of these tissues, approximating and fixating the tissues, and assessing the fixation of the tissues to treat cardiac valve regurgitation, particularly mitral valve regurgitation.

Abstract: The present invention provides methods and devices for grasping, and optional repositioning and fixation of the valve leaflets to treat cardiac valve regurgitation, particularly mitral valve regurgitation. Such grasping will typically be atraumatic providing a number of benefits. For example, atraumatic grasping may allow repositioning of the devices relative to the leaflets and repositioning of the leaflets themselves without damage to the leaflets. However, in some cases it may be necessary or desired to include grasping which pierces or otherwise permanently affects the leaflets. In some of these cases, the grasping step includes fixation.

Abstract: System for fixation of leaflets of a heart valve including an implantable fixation device including a first distal element and a second distal element, a first proximal element moveable relative to the first distal element between a first position and a second position, and a second proximal element moveable relative to the second distal element between a first position and a second position. The system further includes a delivery device including a catheter having a proximal end portion and a distal end portion, the implantable fixation device releasably coupled to the distal end portion of the catheter, the catheter defining at least one lumen extending between the proximal end portion and the distal end portion.

Abstract: Devices, systems and methods for filtering embolic particles that may be generated from a medical procedure including protection of the major branching vessels from the aorta, and catches and filters emboli that may be generated during the TAVR procedure. The filter devices disclosed herein form an improved seal against the vessel wall that is activated by flowing blood. Devices described herein also allow for the closing of the ends of the filter device after capture of emboli, providing further security against accidental loss of emboli post capture.

Abstract: The devices and methods described herein relate to improved structures for removing obstructions from body lumens. Such devices have applicability in through-out the body, including clearing of blockages within the vasculature, by addressing the frictional resistance on the obstruction prior to attempting to translate and/or mobilize the obstruction within the body lumen.

Abstract: The methods, devices, and systems are provided for performing endovascular repair of atrioventricular and other cardiac valves in the heart. Regurgitation of an atrioventricular valve, particularly a mitral valve, can be repaired by modifying a tissue structure selected from the valve leaflets, the valve annulus, the valve chordae, and the papillary muscles. These structures may be modified by suturing, stapling, snaring, or shortening, using interventional tools which are introduced to a heart chamber. The tissue structures can be temporarily modified prior to permanent modification. For example, opposed valve leaflets may be temporarily grasped and held into position prior to permanent attachment. In one aspect, a structure is deployed in a gutter region of the valve annulus to modify the shape of the valve.
