Abstract
Devices and methods for locking and/or cutting tethers during a tissue modification procedure are described. In some variations, a tether may be used to tighten or compress tissue by bringing two pieces or sections of the tissue together. The tether, which may be under tension, may be locked to maintain the tension, and excess tether may be severed, using one or more of the devices and/or methods. The devices and/or methods may be used, for example, in minimally invasive procedures.
Claims20
1-16. canceled
A cutting device comprising:
- an elongate member having a lumen therethrough;
- and
- a rotatable cutter disposed over the elongate member and configured to cut a tether located within the lumen of the elongate member, wherein the rotatable cutter comprises a tube that is concentric with the lumen of elongate member and a cutting element mounted on a distal end of the tube.
A method for cutting a tether, the method comprising:
- tensioning a tether that has been loaded into a cutting device comprising an elongate member having a lumen therethrough and a rotatable cutter disposed over the elongate member, wherein the rotatable cutter comprises a tube that is concentric with the lumen of elongate member and a cutting element mounted on a distal end of the tube, and wherein the tether extends within the lumen of the elongate member;
- and
- distally advancing and rotating the cutter such that the cutting element contacts and cuts the tether.
