The present invention describes systems and methods for treating mitral valve regurgitation. The treatment includes a systems and method of modifying the mitral valve by attaching a device to each leaflet and pulling them toward each other to stop mitral valve regurgitation.

A device for treating a tissue opening includes a proximal portion including an elongated flexible member, a capsule releasably coupled to a distal end of the flexible member and including a lumen extending therethrough and a clip including a pair of arms movably housed within the capsule. A suture extending along a first one of the pair of arms and including a loop at a distal end thereof extending across an opening extending through the first one of the pair of arms. A suture grabbing element extending laterally from a second one of the pair of arms and including a hook so that, when the pair of arms are moved toward a closed configuration, the hook extends through the opening to grab the loop and draw the distal end of the suture from the first one of the pair of arms toward the second one of the pair of arms.

Exemplary medical devices may include a snare device. The snare device may include a first leg having a proximalmost end and a second leg having a proximalmost end. The first leg and the second leg may form a distal loop. The proximalmost end of first leg may be independently moveable relative to the proximalmost end of the second leg.

The shaft-type instrument (1) has a shaft part (2), fixedly connected at one end to a shaft grip (3), and a sliding part (4). The sliding part (4) is displaceably mounted relative to the shaft part (2) and is, at one end, in operative connection with a pretensioned handgrip (5) such that by actuating the handgrip (5), the sliding part (4) is displaceable counter to the pretension. A respective lever arm (7, 7′) is articulated at two spaced apart shaft articulation points (6, 6′) on the shaft part (2) or shaft grip (3). The handgrip (5) has a coupling section (8) which connects the lever arms (7, 7′) and coupling joints (9, 9′) to one another such that same can pivot in the same direction. The coupling joints are spaced apart and a grip section (10) extends transverse to the coupling section (8) and to the shaft part (2).

An endoscopic cap assembly may include a sleeve and a cap. The cap may include a cap channel extending along an external surface of the cap. The cap may also include an engagement feature extending radially outwardly from the external surface of the cap.

A system for excising an implanted clip approximating opposed valve leaflets in a heart valve includes a capture catheter configured to be introduced proximate the valve leaflets on one side of the clip, a transfer catheter configured to be introduced proximate the valve leaflets on another side of the clip, and a cutting tool configured to be deployed between the capture and transfer catheters and to be engaged against tissue of at least one of the valve leaflets and to excise the clip. A removal catheter may optionally be used to remove the clip from the heart.

Apparatuses and methods are disclosed for the perforation of a communication between the aorta and left atrium. The method includes introducing the apparatus, positioning the apparatus at a location along the aorta, and energizing the apparatus to create a perforation. For example, one method may include: introducing a flexible wire into the left atrium, advancing a dilator along the flexible wire to position the flexible wire adjacent a selected location along the aorta and energizing the flexible wire to create a perforation from the left atrium into the aorta.

A septal cross system is provided for a cerclage procedure for treating dysfunctional heart. The cerclage septal cross system includes a puncture catheter and a capture catheter. The puncture catheter a puncture catheter comprises a first lumen for a guidewire to be inserted thereinto. A coil element is arranged in the distal portion of the puncture catheter. The distal end of the pull-wire is attached to the distal portion of the coil element. The proximal end of the pull-wire is extended to the distal portion of the puncture catheter. The pull-wire is configured to bend inwardly the distal portion of the puncture catheter. A capture catheter comprises a first lumen for a first guidewire to be inserted thereinto and a second lumen for a second guidewire to be inserted thereinto. The distal end of the second wire has a snare wherein the distal portion is deflectable.

A joint stabilization (reduction) system and associated methods and tools for placement of the system in an open or minimally invasive technique. The joint stabilization system includes a flexible prosthetic band for stabilizing the bones in proper position and a connector mechanism for joining the two ends of the prosthetic band around the bones. One end of the prosthetic band can be permanently attached to the connector.
