Abstract: A gastric bypass device includes an occlusion device that is adapted to be deployed relative to a patient's pyloric sphincter, an anastomosis anchor that is adapted to be deployed relative to an anastomosis between the patient's stomach and their small intestine, and a tether that extends through the patient's small intestine between the occlusion device and the anastomosis anchor. A dynamic leash may be secured relative to the occlusion device and may work in conjunction with the tether to help hold the occlusion device in place. The gastric bypass device may be deployed using a variety of methods including a push-pull wire method, a rail method, a garage method, a two-piece method and a comprehensive method.

Abstract: In some embodiments, the present disclosure relates to a system. The system includes a substrate and a fluid capture material formed on one or more surfaces of the substrate. The fluid capture material includes a sorbent material that binds one or more fluids, the one or more fluids comprising water, carbon dioxide, sulfur oxides, or a combination thereof. The fluid capture material also includes one or more binder materials, wherein the binder material is at least partially cross-linked.

Abstract: A welding apparatus having a welding tool and a weld cooling apparatus for forced cooling of the weld zone. The welding tool has a welding nozzle with a longitudinal axis, and the weld cooling apparatus uses a source of CO2 as the coolant. A coolant delivery conduit is arranged to move with the welding tool and has a first tube with a longitudinal axis that extends alongside the welding tool, and a second tube with a longitudinal axis extending downwardly and away from the welding tool. A coolant nozzle is located at the end of the second tube to eject coolant at the weld zone. The coolant nozzle outlet is spaced from the workpiece and arranged to direct a jet of coolant behind the welding tool onto the weld zone at least 10 mm from the longitudinal axis of the first tube.

Abstract: An infusion set (10,12) comprises a first part (10) housing a pump and control means and a second part (12) housing a replaceable infusate reservoir (14) with an integral infusion line (16). An anti-freeflow sliding member (26) has an opening (28) through which the infusion line (16) passes, and is slidable between a first open position and a second closed position by detaching the parts.

Abstract: A flexible sheet stacker is described which includes a support surface disposed substantially at right-angles to a flowline along which flexible sheets are fed in spaced relationship. The support surface is adapted to support in a stack the leading edges of the successive sheets fed along the flowline. The pressure-member is arranged to contact a face of a first sheet fed to the support surface and is thereafter movable away from the flowline against biasing means as sheets are progressively fed to the support surface. A wedge shaped separation member is movable along a substantially rectilinear path in advance of a sheet approaching the support surface, the separation member contacting the face of the stack and maintaining the contact during rectilinear movement of the separation means up to the support surface, a face of the stack being thereby displaced laterally out of the path of the leading edge of the approaching sheet as the sheet is advanced up to the support surface.
