Abstract
The present embodiments provide apparatus and methods for treating tissue by applying a force to the tissue. In one embodiment, the apparatus comprises a deployable segment having proximal and distal regions, a main body extending therebetween, and a loop member formed at the distal region of the deployable segment. A cannula having a bore is dimensioned to circumferentially surround at least a portion of the main body at a location proximal to the loop member, and a spring member is disposed between the cannula and the loop member. The proximal end of the spring member is affixed to the cannula, and the distal end of the spring member is movable to apply a compressive force to adjust the size of the opening of the loop member and compress tissue disposed within the opening of the loop member. In an alternative embodiment, the cannula is omitted, and a diameter of the loop member is configured to be reduced and increased any number of times before final deployment of the deployable segment.
