A first end of a wire is transluminally penetrated through tissue at a first cardiovascular site of a subject. A capture device is transluminally advanced into the subject, and is used to capture the first end of the wire and pull the first end of the wire away from the first cardiovascular site. From the first end of the wire, a first anchor is tracked along the wire, and is then anchored to the tissue at the first cardiovascular site. A second anchor is anchored to tissue at a second cardiovascular site. Subsequently, the first and second cardiovascular sites are drawn together by applying tension between the first and second anchors. Other embodiments are also described.

Devices and methods for percutaneous tricuspid valve repair

A catheter system including a wire, a translatable catheter, and first and second tethers is introduced into a body of a subject. The translatable catheter has a curved portion proximate a distal end of the translatable catheter. The first tether is coupled to the wire, and passes proximally through the translatable catheter. The second tether is attached to the curved portion. The catheter system is positioned such that the wire is disposed at a first location in the body. While the wire remains at the first location, the translatable catheter is translated away from the wire by manipulating the first tether and the second tether. Other embodiments are also described.

Translation catheters, systems, and methods of use thereof

A first end of a wire is transluminally advanced to a location adjacent an atrium of a heart of a subject, while a second end of the wire remains disposed outside of the subject. From the location, the first end of the wire is penetrated through tissue into the atrium. A capture device is transluminally advanced into the atrium. Using the capture device, the first end of the wire is captured and pulled out of the subject. From the first end of the wire, a first anchor is tracked along the wire into the atrium, and is anchored to an annulus of a valve of the heart. A second anchor is advanced into the atrium, and is anchored to the annulus. Subsequently, the annulus is reshaped by applying tension between the first and second anchors.

The present teachings provide devices and methods of treating a tricuspid valve regurgitation. Specifically, one aspect of the present teachings provides devices and methods of identifying a suitable location on the tricuspid annulus, another aspect of the present teachings provides devices and methods of placing a wire across the tricuspid annulus at such an identified location, another aspect of the present teachings provides devices and methods of deploying a tissue anchor across such an identified location, and yet another aspect of the present teachings provides devices and methods of applying tension to two or more of such tissue anchors and reducing the circumference of the tricuspid annulus. As a result, a regurgitation jet is reduced or eliminated.

The present teachings generally relate to translation catheter systems and method of using thereof in treating defective mitral valves. Specifically, a translation catheter system includes a catheter configured to move substantially laterally along the mitral annulus and the lateral movement of the catheter is substantially continuous and substantially adjustable. Accordingly, a method of using such a translation catheter includes advancing a first wire across the mitral annulus at a first treatment location, delivering a catheter at or near the first treatment location, moving the catheter substantially laterally to a second treatment location, and advancing a second wire across the mitral annulus, where the distance between the first and second treatment locations is substantially adjustable and optionally visualized.

The present teachings provide devices and methods of treating a tricuspid valve regurgitation. Specifically, one aspect of the present teachings provides devices and methods for reshaping and resizing the right ventricle by reducing the distances between two papillary muscles. Another aspect of the present teachings provides devices and methods for reshaping and resizing the right ventricle by reducing the distances along the right ventricle wall. Another aspect of the present teachings provides devices and methods for reshaping and resizing the right ventricle by reducing the distance between the distance of right ventricle outflow track and the right ventricle wall. Another aspect of the present teachings provides devices and methods for reshaping and resizing the right ventricle by changing the right ventricle sphericity index. Another aspect of the present teachings provides devices and methods for reshaping and resizing the right ventricle by reducing the tricuspid valve tethering height.

Percutaneous valve repair by reshaping and resizing right ventricle

A system is provided for delivering respective anchors into spaced apart locations along an annulus of a mitral valve. The system includes a first catheter member having a first lumen formed therein for receiving a first guide wire and also includes a second catheter member that is configured to move between an expanded position and a collapsed position relative to the first catheter member. The second catheter member has a lumen formed therein for receiving a second guide wire when the second catheter member is in the expanded position. The second catheter member is fixedly connected to the first catheter member by a first connector (that defines first and second living hinges) which is configured to deploy under a select condition to automatically cause the second catheter member to move to the expanded position.
