Abstract: Devices and methods for deploying an anastomotic stent between portions of the gastro-intestinal (GI) tract are disclosed. The anastomotic stents are configured to atraumatically engage the tissue walls and to permit the flow of fluid, partially digested food, and food. The stents can be deployed using endoscopic catheter devices, laparoscopic tools, and combinations of both endoscopic tools and laparoscopic tools. Examples of anastomoses include anastomoses between the stomach and a portion of the intestines such as the jejunum. Anastomoses can also be formed between two closed ends of the intestines, such as two closed ends of the colon formed during a colon resection procedure. Anastomoses can also be formed between a fundal pouch formed during a gastric bypass procedure and the jejunum. Laparoscopic tools are disclosed to deploy a stent by selectively removing a radial restraint on a self expanding stent with the restraint removed through the laparoscopic access points.

Abstract: An implantable fluid operated device includes a fluid control system to transfer fluid between a fluid reservoir and an inflatable member. The fluid control system includes at least one fluid control device including at least one pump and at least one valve, or at least one combination pump and valve device. The at least one fluid control device includes an auxiliary fluid control device that maintains a closed state of the valve in response to a fluctuation in pressure, or a pressure spike that would otherwise cause an unintentional opening of the fluid control device, and unintentional flow of fluid through the fluid control device.

Abstract: Devices, systems, and methods for deploying a biliary stent. A biliary stent has lobes and creases to expand between contracted and expanded positions. The stent is delivered to a bile duct in a contracted position loaded on a shaft of a delivery device. When the shaft is retracted through the stent, wings on the shaft force the stent outward into the larger expanded position. In the expanded position, the creases form drainage channels to reduce blockage over the life of the stent.

Abstract: Medical devices and related methods useful for needle access during medical procedures are described. The medical device may include a needle and a handle coupled to the needle, wherein the handle includes a body comprising a radiolucent material, a first marker proximate a proximal end of the body and a second marker proximate a distal end of the body. Each of the first marker and the second marker may include a radiopaque material, and the first marker may have a shape complementary to the second marker to align a position of the needle relative to a subject when visualized by X-ray imaging.

Abstract: Devices, systems, and methods for a two-way valve assembly for a medical device. The two-way valve assembly has a knob seated within a valve body, two inlet passages leading to a suction source and a gas source, an outlet passage leading to an endoscope fluid channel, and an internal channel connecting one of the two inlet passages to the outlet passage. A spring presses the knob into the valve body to seal the openings along the channels and passages. Rotating the knob slides one or more guide pins on the knob along one or more guide grooves on the body and connects the other inlet passage to the outlet passage, such that the same endoscope fluid channel can be used both for suction, as in clearing fluid from within a patient, and delivering gas, as in insufflation.

Abstract: A catheter system includes a catheter having an elongate shaft, a balloon and a light guide. The balloon expands from a collapsed configuration to a first expanded configuration. The light guide is disposed along the elongate shaft and is in optical communication with a light source and a balloon fluid. A first portion of the light guide extends into a recess defined by the elongate shaft. A protection structure is disposed within the recess and is in contact with the first portion of the light guide. The light source provides pulses of light to the balloon fluid, thereby initiating plasma formation and rapid bubble formation within the balloon, thereby imparting pressure waves upon a vascular lesion. The protection structure can provide structural protection from the pressure waves to the first portion of the light guide.

Abstract: A device for compressing body tissue includes a clip having a connection portion with first and second clip arms extending therefrom, the clip includes a recess formed on an inner surface of the connection portion, the recess being shaped and sized to slidably receive a mounting bar coupled to an outer surface of an endoscope on which the mounting bar is mounted with inner surfaces of the first and second clip arms maintained in an open position by contact between an endoscope on which the mounting bar is mounted and the inner surfaces of the first and second clip arms. The clip is slidable over the outer surface of an endoscope on which the mounting bar is mounted until the clip moves distally beyond the distal end of the endoscope so that the first and second clip arms spring closed to grip tissue therebetween.

Abstract: According to one aspect, a tissue fastening device may comprise a body configured to include a plurality of fasteners; an anvil rotatable relative to the body; and a tissue cutting device. The body may define a longitudinal channel configured to receive the tissue cutting device. The tissue fastening device may further comprise a fastener actuator configured to move proximally relative to the body to deploy the plurality of fasteners from the body; and an actuation wire coupled to the tissue cutting device and the fastener actuator. The actuation of the actuation wire may cause the fastener actuator to deploy at least one of the plurality of fasteners into tissue distally of tissue cut by the tissue cutting device.
