  • Patent number: 10299858
    Abstract: An electrosurgical snare may include a conductive distal loop that includes an uninsulated thinner portion and an uninsulated thicker portion. Respective current densities over the outer surfaces of the thinner and thicker portions may cause the uninsulated thinner portion to immediately begin cutting tissue, while the uninsulated thicker portion may initially begin coagulating the tissue.

  • Patent number: 10045870
    Abstract: The present disclosure provides a support device for a gastrointestinal implant. The support device may include a lumen configured to extend through a submucosal tunnel and a mouth located at a proximal end of the lumen and in fluid communication with the lumen. The mouth may be configured to face proximally within a gastrointestinal tract to receive GI contents, and the mouth may be configured to direct the GI contents into the lumen. The support device may further include a support structure, where the lumen extends through the support structure, and where the support structure is configured to apply an outward radial force on an inner wall of the gastrointestinal tract. An artificial tunnel may extend distally from the support structure, may form at least a portion of the lumen, and may be configured to extend through the submucosal tunnel.

  • Publication number: 20180125573
    Abstract: A bipolar sphincterotome may include an elongate tubular member, a cutting wire, and a return path. The return path may include a conductive ink portion disposed on an outer surface at a distal portion of the tubular member. The return path may also include a return wire disposed within the tubular member that is electrically coupled to the conductive ink portion. In some example embodiments, the return wire may be disposed within a lumen configured to have two or more functions, one of which being to house the return wire. Additionally, in some example embodiments, the conductive ink portion may be circumferentially disposed on the outer surface to provide visual access to a wire guide lumen. Also, for some example embodiments, the bipolar sphincterotome may include two electrically isolated return paths.

  • Patent number: 9451875
    Abstract: A flexible lens is mounted to the end of an elongate medical device having a camera, such as an endoscope. The lens is generally solid and is made from a translucent, flexible, and resilient material. In a medical environment, the lens can be pressed against a vessel wall in a patient to enlarge the area viewed by the camera, and can further adapt to the shape of the wall to limit trauma on the patient. When pressed against the vessel wall, the lens can become longitudinally compressed, while becoming wider. The wider and compressed shape of the lens will push blood away from the viewing area to increase the clarity of the camera's field of view.

  • Publication number: 20160175043
    Abstract: Electrosurgical medical systems and methods for maintaining a target tissue portion in a raised position are disclosed. In one embodiment, the target tissue portion may be withdrawn into a distal chamber of an electrosurgical device using a proximal bias. An electrode assembly of the electrosurgical device may contact a base of the target tissue portion. The electrode assembly may apply an electrical current to coagulate the target tissue portion while the proximal bias is being applied. Suction and electrical current may be applied without detaching the target tissue portion from the underlying tissue.

  • Patent number: 9364277
    Abstract: A control unit controls delivery of RF energy generated by an RF generator to a medical device configured to perform a medical procedure. The control unit may be separate from the RF generator, and may have an input that may be attached to an output of the RF generator. The control unit includes switching circuitry that is closed while an amount of RF energy is transmitted through the control unit to the medical device. The switching circuitry opens when the amount of RF energy reaches a threshold level.
