Fixation device for engaging tissue including a pair of fixation elements, each fixation element has a first end and a second end opposite the first end, the first ends are moveable between a closed position and an open position. The fixation device further includes a pair of gripping elements. Each gripping element is moveable with a respective fixation element and disposed in opposition to at least a portion of the respective fixation element to capture tissue therebetween. The fixation device further includes a central portion operatively connected to each gripping element at a respective central portion-gripping element interface. The central portion has at least one distal end and a width 'W' proximate the distal end. Each of the gripping elements has a free end opposite its respective central portion-gripping element interface and a length “L” defined between the respective central portion-gripping element interface and the free end. The length Lfixation elements is at least about three times the width W.

Long arm valve repair clip

Fixation device for fixation of leaflets of a heart valve includes a central assembly and at least one arm moveably coupled relative to the central assembly. The at least one arm includes a deformable frame having a first end and a second end and a longitudinal axis defined therebetween, the second end being moveable between a closed position and an open position. The deformable frame further includes first and second deformable flex portions, each flex portion extending along a respective lateral side of the deformable frame and having a deformed condition and an undeformed condition, and each flex portion having an outer lateral edge. The at least one arm has a maximum deformed arm lateral cross-dimension with the flex portions in the deformed condition.

Wide clip with deformable width

Fixation system for engaging tissue of a patient including an implantable fixation device having a first arm and a second arm, a first proximal element, a second proximal element, and a coupling member. The system includes a delivery device having a catheter, a shaft extending through the at least one lumen of the catheter, a first proximal element actuator and a second proximal element actuator. The second end portions of the first proximal element actuator and second proximal element actuator can be coupled to at least one of the shaft and the coupling member.

Proximal element actuator fixation and release mechanisms

The present disclosure relates to delivery devices and interventional devices configured to enable monitoring of pressure and other hemodynamic properties before, during, and/or after a cardiac procedure. A guide catheter includes a routing lumen or a routing groove for routing a sensor wire to a desired location during a cardiac procedure. A guide catheter includes one or more pressure sensors positioned to provide desired pressure measurements when the guide catheter is deploying an interventional device. An interventional device may also include one or more associated sensors for providing hemodynamic information before, during, and/or after deployment.

Systems and methods for intra-procedural cardiac pressure monitoring

Fixation device for engaging tissue including a pair of fixation elements, each fixation element has a first end and a second end opposite the first end, the first ends are moveable between a closed position and an open position. The fixation device further includes a pair of gripping elements. Each gripping element is moveable with a respective fixation element and disposed in opposition to at least a portion of the respective fixation element to capture tissue therebetween. The fixation device further includes a central portion operatively connected to each gripping element at a respective central portion-gripping element interface. The central portion has at least one distal end and a width 'W' proximate the distal end. Each of the gripping elements has a free end opposite its respective central portion-gripping element interface and a length 'L' defined between the respective central portion-gripping element interface and the free end. The length Lfixation elements is at least about three times the width W.

A method for improving function of a cardiac valve in a patient, the cardiac valve having at least one leaflet that is attached to a papillary muscle: Inserting a balloon, that is in a first uninflated condition and having a first diameter, within tissue that is part of to the papillary muscle, and thereby separating tissue that was previously connected together, by a maximum amount equal to the first diameter; inflating the balloon to a second inflated condition having a second diameter greater than the first diameter, thereby permanently stretching tissue in the papillary muscle and separating the tissue from the first diameter to a maximum amount equal to the second diameter; deflating the balloon to the first uninflated condition, and thereby returning the tissue to a separation of a maximum amount substantially equal to the first diameter; and then removing the balloon from the patient.

System and method for correcting valve regurgitation

A method for measuring the force necessary to dislodge a stent from a balloon catheter to which it is mounted. The balloon catheter with a stent mounted thereon is encased in a mass of gel material. The force necessary to pull the catheter from the gel is measured.
