Abstract: An electrotherapeutic device can be configured for at least partial insertion into a patient. The device can include a shaft including a proximal portion and a distal portion, a gas-delivery lumen extending between the proximal portion and the distal portion of the shaft, and one or more electrodes located near the distal portion of the shaft. The electrodes can include a plasma activation electrode for generating plasma from gas delivered to the distal portion of the shaft via the gas-delivery lumen, and an ablation electrode for generating electromagnetic ablation energy. The medical device can be used in a method of treating endometriosis including delivering a gas toward an in vivo treatment site within a patient, generating plasma from the gas on or near the in vivo treatment site using a plasma activation electrode, exposing the treatment site to the plasma, and applying electromagnetic ablation energy to treat endometrial tissue.

Abstract: A stent, shunt, or plug, for at least partial insertion into a patient, can include a deformable elongated tubular body including a proximal portion and a distal portion and defining a longitudinal lumen of the tubular body therebetween. The deformable elongated body can be capable of an expanded state and a collapsed state. The tubular body can include a sheath and a plurality of magnetizable or magnetic elements for providing magnetic repulsion, after being magnetically actuated, to maintain the tubular body to maintain the expanded state.

Abstract: A method of treating diverticulitis and the diverticulum by reducing the bioactivity of the diverticulum such that the diverticulum necroses. The devices and methods include placing an endoscopic device within a colonic lumen relative to at least one diverticulum and inverting the diverticulum. Once inverted, the diverticulum is collapsed and sealed. Overtime, the inverted diverticulum will necrose and be absorbed by the body or slough off and be expelled.

Abstract: An elevator for an endoscope comprises a first end secured to the endoscope, a second end movable by an actuator, a flexible portion positioned between the first and second ends that is rotatable when the second end is moved by the actuator, and a guide portion extending between the flexible portion and the second end to receive an endotherapy instrument extending from the endoscope, the guide portion comprising a chute to guide the endotherapy instrument leaving the endoscope. A method of forming an elevator comprises forming from a planar sheet of material an elongate body comprising a length between first and second ends, a width, and a thickness, forming a guide body in the elongate body, bending the elongate body such that first and second lengths of the elongate body oppose each other to form an interior space, and bending the guide body to extend into the interior space.
