Abstract: The anti-obesity diverter structure includes a laminate structure having papilla-supplied and pylorus-supplied surfaces. The laminate structure is sized to fit longitudinally within a duodenum such that a transverse clearance is provided between the papilla-supplied surface and papilla of Vater. The laminate structure is secured within the duodenum to define papilla-supplied and pylorus-supplied lumens therein. The papilla-supplied lumen receives the digestive fluid from the papilla of Vater, and provides a conduit for the digestive fluid therein. The pylorus-supplied lumen receives the chyme from the pylorus and provides a conduit for the chyme therein. The laminate structure is impervious or semi-permeable to the chyme and digestive fluid.

Abstract: The anti-obesity stent includes a tubular structure having outer and inner surfaces and proximal and distal ends. The tubular structure is sized to fit within a duodenum in substantially coaxial relation therewith. The tubular structure is impervious or semi-permeable to digestive substances and chyme within the duodenum. The anti-obesity stent includes a transport structure at least a part of which is coincident with or connected to the outer surface. The transport structure extends to the distal end of the tubular structure. At least one retainer structure is connected to the tubular structure. The retainer structure secures the tubular structure within the duodenum such that the transport structure is positioned to receive digestive fluids from a papilla of Vater on an inner surface of the duodenum. The transport structure provides a conduit for the digestive fluids therein to flow to the distal end.

Abstract: Hashing and pattern matching are used in an information processing system to process incoming messages from a network such as an Ethernet-based network. Using hashing and pattern matching increases the efficiency of message acceptance and rejection without increasing software-based processor tasks. A hash function and a pattern matching function are performed on a message received by an information processing system, and the message is selectively accepted based on at least one of a hash result and a pattern matching result. The incoming message can be searched for the existence of patterns and the absence of the patterns. The incoming message can be searched for the existence of multiple patterns. The results of pattern matching can be used not only for acceptance and rejection of messages, but also for other post-receipt tasks such as selective storage of incoming messages according to identified relative priorities or absolute criticality of messages having particular pattern matches.

Abstract: A port device for implanting in a patient for subcutaneous access to the vascular system of the patient. The device includes a housing provided with apertures, each for receiving and retaining a needle. The housing is further provided with lock structure for locking catheters to the housing. The housing is configured internally to provide flow paths extending between needles disposed in the apertures and the catheters.

Abstract: A method for fixing a portion of a piece of tissue in a bone tunnel comprising the steps of placing the portion of a piece of tissue in the bone tunnel, advancing spaced-apart first and second metal wires though the bone, transversely of the bone tunnel, so as to intersect the bone tunnel and extend into the portion of a piece of tissue, removing one of the wires and replacing the one removed wire with a first rod, and removing the other of the wires and replacing the other removed wire with a second rod, whereby to retain the portion of a piece of tissue in the bone tunnel with the rods.

Abstract: A graft ligament anchor comprises a graft ligament engagement member disposed in an opening in a bone, the graft ligament engagement member being arranged to receive a graft ligament alongside the engagement member, and a locking member for disposition in the opening, and at least in part engageable with the graft ligament engagement member. Movement of the locking member in the opening causes the locking member to urge the engagement member, and the graft ligament therewith, toward a wall of the opening, to secure the graft ligament to the wall of the opening.

Abstract: A method for fixing a bone block in a bone tunnel comprising the steps of placing the bone block in the bone tunnel, advancing spaced-apart first and second metal wires through the bone, transversely of the bone tunnel, so as to intersect the bone block and extend through the bone block, removing one of the wires and replacing the one removed wire with a first absorbable rod, and removing the other of the wires and replacing the other removed wire with a second absorbable rod, whereby to retain the bone block in the bone tunnel with the absorbable rods.
