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.

Abstract: An expandable ablation catheter includes an expandable section having a plurality of channels defining struts. The expandable section has at least one conductor on one of the struts configured to couple to an energy source. The expandable section is expandable through longitudinal compression to expand the strut having the conductor outward to contact an inner surface of a lumen.

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.

Abstract: Medical systems, devices and methods are provided for engaging tissue, e.g. for clipping tissue, closing a perforation or performing hemostasis. Generally, the medical system including a housing, first and second jaws rotatable relative to the housing, a driver, and an elongate drive wire. The elongate drive wire may be disconnected from the driver, first and second jaws, and the housing, which are left in vivo engaged with the tissue.

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.

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.

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.

Abstract: A fluoropolymer medical device (e.g., a sphincterotome) has a thin-film coating deposited using a technique such as Atomic Layer Deposition. The thin-film coating may be a ceramic coating or a metal coating and a ceramic coating may further have an overlying ink coating such as a conducting ink or a radiopaque marker. The ceramic coating improves the application and adherence of the ink coating to the fluoropolymer device.

Abstract: Medical devices, systems and methods are disclosed that serve to guide one or more medical devices through a port formed in bodily tissue to access a bodily cavity. One embodiment of the medical device includes a connection member, a rail, and a carrier. The connection member is structured for attachment to the port. The rail is attached to the connection member, and has a first portion extending distally through the port opening, and a second portion extending at an angle relative to the first portion. The carrier is structured to selectively connect to the first portion of the rail, and is slidable along the first and second portions of the rail.
