Abstract: An electrosurgical device is provided for removing polyps from the gastrointestinal tract of a patient. In one implementation, an electrosurgical device comprises a snare support member and a snare positioning assembly mounted on an exterior surface of the snare support member. The snare positioning assembly has a longitudinal axis substantially parallel with and offset from the longitudinal axis of the snare support member. The device also includes a base member attached to a distal end of the snare support member and has a longitudinal axis substantially aligned with the longitudinal axis of the snare support member. An aperture is formed through a side wall of the base member. Also included is a polyp snare extending through a first channel of the snare positioning assembly, through the aperture, and through a second channel of the base member.

Abstract: An electrosurgical device for use with an electrosurgical generator to remove polyps from the gastrointestinal tract comprising a hand piece including a body or housing having an operator handle and a snare support attached thereto, a snare guide including a snare channel formed therethrough to slidably receive at least a portion of a polyp snare including a snare loop therein and a snare positioning assembly coupled to the polyp snare to selectively move the polyp snare between an extended portion and a retracted position attached to the snare support and a remote switch assembly coupled between the electrosurgical generator and the snare positioning assembly to selectively energize the electrosurgical generator, to selectively operate the snare positioning assembly to move the polyp snare from the retracted position to the extended position such that the snare loop encircles a polyp to be removed from the gastrointestinal tract and to selectively supply energy from the electrosurgical generator to the snare
