Abstract
An anchor capable of being delivered in a delivery configuration and deployed through anatomical tissue with the use of a delivery device. Upon deployment, the anchor shifts into a deployment configuration with at least a distal anchor portion extending transverse to a medial portion of the anchor. The anchor is removable from the anatomical tissue with the use of a retrieval device which grasps a proximal end of the anchor and proximally retracts the anchor into a flexible tubular element to return the anchor to the delivery configuration.
Claims20
An anchor capable of extending through anatomical tissue at a deployment site, said anchor comprising:
- a distal end forming a distal anchor portion;
- a proximal end forming a proximal anchor portion;
- and
- a medial portion, between the distal end and the proximal end, configured to extend through anatomical tissue;
- wherein:
- said anchor is shiftable between an elongated delivery configuration and a deployed configuration;
- at least said distal anchor portion is formed when said anchor shifts into the deployed configuration by bending into a configuration extending transverse to said medial portion;
- and
- a free end of said proximal anchor portion extends away from the deployment site to facilitate access thereto for removal of the anchor from the deployment site.
A system for delivering, deploying, and retrieving an anchor with respect to anatomical tissue, said system comprising:
- an anchor having a distal end forming a distal anchor portion, a proximal end forming a proximal anchor portion, and a medial portion between the distal anchor portion and the proximal anchor portion, said anchor being shiftable between an elongated delivery configuration and a deployed configuration;
- a delivery device comprising a flexible tubular element defining a lumen therethrough, the lumen configured to retain said anchor in the elongated delivery configuration therein;
- and
- a retrieval device comprising an anchor-engaging element configured to engage said proximal anchor portion to proximally retract the anchor from the deployment site, and a tubular element defining a lumen therethrough configured to retain said anchor in the elongated delivery configuration.
A method of deploying an anchor with respect to anatomical tissue, and subsequently removing the anchor from the anatomical tissue, said method comprising:
- delivering an anchor in an elongated delivery configuration to the anatomical tissue;
- deploying the anchor to allow the anchor to shift from the elongated delivery configuration to a deployed configuration in which at least a distal anchor portion is formed extending transverse to and away from a medial portion of the anchor;
- and
- removing the anchor after a selected period of time by withdrawing the anchor proximally to cause the distal anchor portion to return to the elongated delivery configuration and be withdrawn proximally through the anatomical tissue and withdrawn therefrom.
