MINIMALLY INVASIVE MITRAL VALVE REPAIR METHOD AND APPARATUS |
摘要 |
The present invention is directed to an apparatus and method for the stabilization and fastening of two pieces of tissue. A single device may be used to both stabilize and fasten the two pieces of tissue, or a separate stabilizing device may be used in conjunction with a fastening device. After the pieces of tissue are stabilized, they are fastened together using sutures or clips. One exemplary embodiment of a suture-based fastener comprises a needle connected to a suture. The needle enters the blind side of the tissue and exits the front side. The suture is then tied in a knot to secure the pieces of tissue. One example of a clip-based fastener comprises a spring-loaded clip having two arms with tapered distal ends and barbs. The probe includes a deployment mechanism which causes the clip to pierce and lockingly secure the two pieces of tissue.
