Abstract: A delivery system for placing a gastrointestinal device in a mammalian gastrointestinal tract comprises a container assembly; a gastrointestinal implant device that includes proximal and distal ends stored within the container assembly, the proximal end including an anchor and the distal end including a sleeve, coupled to the anchor and folded into the container assembly; and an inner extension to draw a portion of the sleeve from the anchor and from the container assembly as the anchor is retained therein. The inner extension comprises an atraumatic tip, such as a ball, that includes a guidewire rail. Further, a handle is provided that retains or captures an inner catheter within the handle. Within the handle is an elongated element that surrounds a portion of the catheter. A button on a side of the handle is configured to cause engagement of the catheter via the element when the button is depressed.

Abstract: A gastrointestinal implant device comprises a proximal element configured to reside in a stomach to resist distal migration; a distal element configured to reside in an intestine to resist proximal migration, and one or more tethers coupling the proximal element to the distal element. The distal element comprises a wave anchor and a surface roughness element on a surface of at least a portion of the wave anchor. Delivery systems and retrieval techniques are also provided.

Abstract: An implant (100) includes a protrusion (110) with an open or rounded loop (112) (or open head) connected to a collapsible anchor. The protrusion may include a straight length of wire (114) or a helical length wire, with one or more wire loops (112) at the end of the length forming the loop. Upon deployment within the gastrointestinal tract, the protrusion expands from a collapsed state, alongside the anchor, to a relaxed state, in which the protrusion extends outward from the anchor. As the protrusion expands to its relaxed state, it pushes the loop into the wall of the duodenum, causing the loop to penetrate the duodenal wall. A pocket of scar tissue forms about the head and possibly through an opening in the head, securing the anchor within the duodenum. The implant may also include a thin-walled sleeve that is coupled to the anchor and extended from the anchor into the intestine.

Abstract: Gastrointestinal implants in areas such as the esophageal area, the stomach, and the intestinal area are used in the treatment of conditions like obesity and diabetes. An implant including an anchor with barbs having pores, can allow for longer term anchoring. The pores can promote tissue ingrowth from the surrounding tissue that the barb is penetrating, thus advantageously allowing increased stability and longer term anchoring compared to a non-porous barb.

Abstract: An endoscope accessory capable of being removably coupled to the accessory port of an endoscope includes a housing having an introducer port adapted for insertion of an elongated member, a device port adapted for alignment with the accessory port, a fluid port in fluid communication with the device port, and a fluid-tight seal, which forms a seal around the elongated member. The accessory includes a coupling mechanism to couple the accessory to the accessory port to assist in an endoscopic procedure. For example, the elongated member can be inserted through the introducer port, into the accessory port with which the device port is aligned, and into a patient's gastrointestinal tract. The patient's tissue may be irrigated by injecting fluid through the fluid port while the elongated member is manipulated. A locking mechanism, coupled to the housing, can be used to secure the elongated member with respect to the endoscope.

Abstract: The invention is directed to a container for storage, dispensation, transport and disposal of a medical device such a disposable ultrasonic surgical probe, that allows its dispensation for use, and for its safe storage and disposal after use, thereby protecting the user from the hazards of needle pricks and possible contamination from small-diameter probes. The container of the present invention also provides a mechanism for restricting access to the probe to prevent its reuse, and a method for its safe attachment to and detachment from an ultrasonic medical device. The container comprises a cylindrical tube having two ends and an inner surface defining a space for containing the probe.
