A surgical fastening instrument can comprise a handle and an end effector, wherein the end effector can comprise a first jaw comprising a first cartridge attachment portion and a second jaw comprising a second cartridge attachment portion, and wherein one of the first jaw and the second jaw is movable relative to the other of the first jaw and the second jaw. The surgical fastening instrument can further comprise a first cartridge that is insertable into the first jaw and attachable to the first cartridge attachment portion and, in addition, a second cartridge that is insertable into the second jaw and attachable to the second cartridge attachment portion. In various embodiments, the first cartridge can comprise first fastener portions which are engageable with second fastener portions in the second cartridge.

A surgical fastener system can comprise a plurality of fasteners which can be connected to one another by a retention matrix which is assembled to the fasteners in order to capture tissue therebetween. In various embodiments, each fastener can comprise a base and the distance in which the retention matrix is seated relative to the fastener bases can be selectively determined by a surgeon in order to apply a desired pressure to the tissue. In certain embodiments, each fastener can further comprise a fastener leg and the retention matrix can comprise a first layer configured to engage the fastener legs. The retention matrix can further comprise a second layer mounted to the first layer which can comprise one or more encapsulations containing a medicine therein. The encapsulations can be aligned with retention apertures in the retention matrix such that they can be punctured by the fastener legs.

An apparatus comprises a shaft, a needle throwing arm, and a needle receiving arm. The arms are movable asynchronously along planes that are substantially parallel to a longitudinal axis defined by the shaft. The arms selectively engage a surgical needle, such that the throwing arm may pass the surgical needle through tissue for receipt by the receiving arm, and the receiving arm may then pass the surgical needle back to the throwing arm for additional stitching. The arms may pivot about a common pivot. Such versions may include a single actuator for both arms or separate actuators for the arms. The arms may also pivot about their own respective axles, which may facilitate a forward reset motion for a needle, allowing the needle to continue travelling along a circular path in a single direction to create several stitches. The apparatus may also convert reciprocating movement of actuators into rotational motion.

A method for regulating hormone production comprises placing at least one electrode in a gastrointestinal tract of a patient and recording an electrical signal during a preselected event produced by the gastrointestinal tract. The method further involves the steps of storing the electrical signal, and playing back the electrical signal by activating the electrode during the absence of the preselected event.

Methods and devices create an intestinal braking effect, are non-invasive or minimally invasive, and may be reversible. These methods and devices are accomplished via stabilized implantable systems and ingestible pills. In one embodiment, a method of producing satiety comprising the steps of accessing a gastrointestinal tract of a patient and implanting an intraintestinal therapeutic substance eluting implant. The implant is capable of eluting a satiety inducing substance selected from at least one of a nutrient, a specific satiety inducing bio-active substance, pancreatic polypeptides, free fatty acids, cholecystokinin, amino acids, glutamine, lipids, linoleic acid, or a combination thereof, from the implant into the gastrointestinal tract.

Methods and devices reroute chyme to induce intestinal brake in order to improve the effectiveness of bariatric surgical procedures and to improve comorbidity resolution. A bowel is manipulated to provide a shortened path for chyme to travel to the ileum. These methods and devices of rerouting chyme to induce intestinal brake may comprise one or more of a surgical procedure, an implanted device, or a combination of an implant with an improved surgical procedure.
