Abstract: Apparatuses, systems, and methods are disclosed for providing controlled delivery of energy treatment to a tissue site. The systems, apparatuses, and methods may include designs with features for efficiently deploying and adjusting electrodes at a tissue site for treatment and for facilitating retraction of the electrodes back into a housing after completion of treatment for removal. The systems, apparatuses, and methods may further include an expansion member for radially expanding the flexible substrate to aid in positioning the electrodes adjacent the tissue to facilitate treatment.

Abstract: Apparatuses, systems, and methods are disclosed for providing controlled delivery of energy treatment to a tissue site. The systems, apparatuses, and methods may include medical instrument designs with features for retaining a flexible substrate with an electrode array in position against an expandable member during delivery to the tissue site, treatment, and retraction from the tissue site. The medical instrument further includes features for retaining the flexible substrate in a compact, stowed configuration during delivery and for retracting the flexible substrate post-deployment to facilitate retraction of the medical instrument after completion of treatment.

Abstract: An electrode treatment device includes an electrode strip arranged in the shape of a helix with a first end of the electrode strip attached to an elongate flexible body, such as a catheter tube, and a second end of the electrode strip attached to a flexible shaft that extends from the body. When the helical electrode is contracted around the body and/or shaft, the device may be less than 2 mm in diameter to facilitate endoluminal insertion and treatment of gastrointestinal or lung tissue, for example. The shaft is rotatable relative to the body to radially expand the helix to a deployed position in apposition to target tissue for electrosurgical treatment (e.g., treatment in a lumen). The electrode strip may consist of conductive foil or may comprise a flexible printed circuit with one or more electrodes formed thereon. The device may be operated by a robotic manipulator.

Abstract: A surgical clip includes an elongated body configured to be detachably coupled to a shaft of a surgical instrument, a pair of jaw members received in the body, and a release feature for selectively unlocking the jaw members.

Abstract: A surgical system for performing an endoscopic submucosal dissection includes first and second surgical clips each having first and second jaw members for grasping tissue therebetween. The first surgical clip includes a resilient member attached to one of the jaw members and configured to bow outwardly to engage tissue. The jaw members of the first surgical clip each has a pointed tip and each of the jaw members of the second surgical clip has a blunt distal tip.

Abstract: A tissue clip includes an elongate body configured to be detachably coupled to a shaft of a surgical instrument, a pair of jaw members received in the elongate body, and a resilient member configured to bow outwardly from the elongate body upon deployment of the tissue clip at a surgical site.
