Abstract
A medical device includes a sheath extending from a proximal end to a distal end and having a lumen extending therethrough and an end-effector disposed at the distal end of the sheath including a first resection loop configured to resect tissue and a secondary tool including one of a second resection loop and a tissue-vaporizing structure mounted distally to the first resection loop.
Claims20
A medical device, comprising:
- a sheath extending from a proximal end to a distal end and having a lumen extending therethrough, wherein the sheath extends along a longitudinal sheath axis;
- and
- an end-effector disposed at the distal end of the sheath including:
- a first resection loop having a fully expanded configuration;
- a second resection loop mounted distally of the first resection loop and having a fully expanded configuration, wherein each of the first resection loop and the second resection loop is individually expandable to its fully expanded configuration radially outwardly from an outer wall of the sheath relative to the longitudinal sheath axis;
- and
- a tissue vaporizer mounted to the outer wall of the sheath distally of the second resection loop, wherein the tissue vaporizer is a button electrode;
- wherein, in an insertion configuration, the first resection loop is positioned against the outer wall of the sheath.

An end-effector for a medical device, comprising:
- a first resection loop having a fully expanded configuration;
- a second resection loop mounted distally relative to the first resection loop and having a fully expanded configuration, wherein each of the first resection loop and the second resection loop is individually expandable between an insertion configuration and its fully expanded configuration relative to an end-effector longitudinal axis;
- and
- a button electrode mounted to a circumferential wall of the end-effector distally of the second resection loop;
- wherein the first resection loop extends from a first opening and a second opening, different than the first opening, in the circumferential wall of the end-effector.
2 more elements
An end-effector for a medical device, comprising:
- a first resection loop;
- a second resection loop, wherein each of the first resection loop and the second resection loop is movable between an insertion configuration and a fully expanded configuration, wherein in the fully expanded configuration, each of the first resection loop and the second resection loop extends radially outwardly from an outer wall of a sheath having a longitudinal axis;
- and wherein, in the fully expanded configuration, the second resection loop extends farther radially outwardly of the outer wall of the sheath than the first resection loop relative to the longitudinal axis;
- and
- an electrode extending radially outwardly from the outer wall of the sheath relative to the longitudinal axis, wherein the electrode is a button electrode coupled to the outer wall of the sheath and positioned distally of both of the first resection loop and the second resection loop;
- wherein the first resection loop extends from a first opening and a second opening, different than the first opening, in the outer wall of the sheath.
