Abstract
A method for removing tissues may comprise disposing a tissue resection device at a target tissue site, causing the tissue resection device to resect a core of tissue from the target tissue site, removing the core of tissue from the body, wherein the removing the core of tissue from the body creates a core cavity at the target tissue site.
Claims31
A method for coring tissue, the method comprising:
- disposing a tissue resection device near a target tissue site;
- rotating a helical coil of the tissue resection device distally through tissue towards the target tissue site;
- clamping a portion of tissue between a first electrode of a first clamping element and a second electrode of a second clamping element of the tissue resection device, the second electrode being arranged proximal to the first electrode and configured to advance toward the first electrode to clamp the portion of tissue;
- sealing the portion of tissue clamped between the first electrode and the second electrode by energizing at least one of the first electrode or the second electrode;
- advancing a cutting element slidably disposed within the second clamping element of the tissue resection device to cut the portion of tissue to form a section of cored tissue;
- repeating the rotating, the clamping, the sealing, and the advancing steps until the cored tissue is a predetermined size;
- and removing, after the cored tissue is the predetermined size, the cored tissue from the body, wherein the removing the cored tissue from the body creates a cored cavity at the target tissue site.

A method for coring tissue, the method comprising:
- disposing a tissue resection device near a target tissue site;
- rotating a helical coil coupled to a first tube of the tissue resection device distally through tissue towards the target tissue site;
- advancing a distal edge of a second tube of the tissue resection device towards the target tissue site such that a portion of tissue is clamped between a first electrode disposed on a proximal surface of the helical coil and a second electrode disposed on the distal edge of the second tube of the tissue resection device;
- and energizing at least one of the first electrode or the second electrode with radiofrequency energy;
- advancing a cutting element disposed within the second tube of the tissue resection device to cut the portion of tissue to form a section of cored tissue.

A method for coring tissue, the method comprising:
- disposing a tissue resection device near a target tissue site;
- rotating a helical coil of the tissue resection device distally through tissue towards the target tissue site;
- clamping, after rotating the helical coil, a portion of tissue between a first electrode and a second electrode of the tissue resection device by advancing the second electrode distally toward the first electrode to clamp the portion of tissue between the first electrode and the second electrode, the second electrode being disposed on a distal edge of a tube;
- sealing, after the clamping, the portion of tissue clamped between the first electrode and the second electrode by energizing at least one of the first electrode or the second electrode with radiofrequency energy;
- and advancing, after the sealing, a cutting element slidably disposed in the tube of the tissue resection device to cut sealed tissue to form a section of cored tissue.
