Systems and methods for treating tissue with radiofrequency energy
First Claim
1. A device for applying radiofrequency energy for sphincter treatment comprising:
- a flexible outer tube;
an expandable basket having a plurality of arms movable from a collapsed position to an expanded position, and an opening in each of the arms of the plurality of arms;
a plurality of electrodes movable with respect to the plurality of arms, each electrode of the plurality of electrodes is movable from a retracted position to an extended position to extend through each of the openings in each arm of the plurality of arms;
an advancer slidably disposed within the outer tube, the plurality of electrodes operably coupled to the advancer such that movement of the advancer advances each electrode of the plurality of electrodes through each of the openings in each arm of the plurality of arms to the extended position;
a handle portion;
an actuator extending from the handle portion for moving the advancer from a first position to a second position to advance the plurality of electrodes;
an aspiration tube extending within the outer tube and having an opening in a sidewall inside the handle portion; and
an assembly at the handle portion for disabling aspiration through the aspiration tube, the assembly including a disabler having a first position to enable aspiration from a distal portion of the aspiration tube to a proximal portion, the disabler movable to a second position to disable aspiration, the side opening in the aspiration tube communicating with a space within the handle portion to enable air escape into the handle portion when the disabler is moved to the second position.

Abstract
A device for applying radiofrequency energy for sphincter treatment comprising a flexible outer tube, an expandable basket having a plurality of arms movable from a collapsed position to an expanded position, and a plurality of electrodes movable with respect to the arms from a retracted position to an extended position. An advancer is slidably disposed within the outer tube to move the plurality of electrodes to the extended position. An actuator moves the advancer from a first position to a second position to advance the plurality of electrodes. An aspiration tube extends within the outer tube. An assembly includes an aspiration disabler having a first position to enable aspiration from a distal portion of the aspiration tube to a proximal portion and a second position to disable aspiration.
