Abstract
Medical devices, systems, and related methods of use are disclosed. The systems may comprise a sheath for insertion into a body lumen and an extraction tool for passage through the sheath, wherein the extraction tool may include a handle, an end effector, and an optical device. Methods disclosed herein include introducing an extraction tool into a urethra for retrieving and removing tissue from the body, e.g., with an end effector, without morcellating the excised tissue.
Claims19
A method of removing tissue from a body, the method comprising:
- introducing an extraction tool into a urethra, the extraction tool extending between a proximal end and a distal end, wherein the distal end includes an expandable end effector that forms an at least partially conical shape with a solid circumferential wall in an expanded state, and wherein the extraction tool includes a central channel with an interior diameter greater than about 20 Fr;
- grasping the tissue with the end effector to enclose the tissue within the expandable end effector in the expanded state such that the tissue is surrounded by the solid circumferential wall of the end effector;
- and
- without morcellating the tissue, removing the extraction tool from the body with the tissue enclosed.
A method of performing holmium laser enucleation of the prostate, the method comprising:
- excising prostate tissue with a laser apparatus;
- moving the excised tissue into a bladder;
- introducing an extraction tool into a urethra and advancing the extraction tool toward the bladder, the extraction tool extending between a proximal end and a distal end, wherein the distal end includes an expandable end effector that forms an at least partially conical shape with a solid circumferential wall in an expanded state, and wherein the extraction tool includes a channel with an interior diameter greater than about 26 Fr;
- grasping the excised tissue with the end effector to enclose the tissue within the expandable end effector in the expanded state such that the tissue is surrounded by the solid circumferential wall of the end effector;
- and
- removing the extraction tool from the body with the excised tissue enclosed without morcellating the tissue.
