Abstract
A tissue connecting device is provided. The device comprise an elongate delivery device having a lumen, a proximal end, and a distal end. The distal end is configured to engage tissue and advance the device into tissue. At least one anchor deliverable through a lumen of the elongate delivery device. The distal end of the device may be designed to engage tissue upon rotation of the device about its longitudinal axis.
Claims18
A tissue anchor assembly, comprising;
- a helical tissue anchor capable of piercing tissue through rotation,
- a suture coupled to a distal end of the helical tissue anchor and configured to provide that as more force is applied to the helical tissue anchor by the suture, the helical tissue anchor collapses upon itself and provides additional support to tissues in which it is attached;
- a tissue support member;
- a clamp coupled to the suture to provide tension between the tissue support member and the anchor, and
- a releasable elongated delivery device with a distal end configured to releasably engage the anchor, the elongated delivery device including engagement threads that allow rotation of the helical tissue anchor for securement.
