Various methods and devices are provided for accessing a body cavity. In one embodiment, a surgical access device is provided and includes an elongate member having a proximal support member configured to rest against an external tissue surface, a flexible elongate central portion extending distally from the proximal support member and configured to extend through tissue, and an inflatable distal portion coupled to a distal end of the central portion. The distal portion is movable between an initial configuration, in which the distal portion is configured to be passed through an incision in tissue, and an inflated configuration in which the distal portion is expanded such that the central portion forms a working channel through the tissue for access to a body cavity. The distal portion can include an opening such that gas delivered to the distal portion can flow through the opening to insufflate a body cavity.

Methods and devices are provided for providing access through tissue to a surgical site. In one embodiment, a surgical access device can include a hollow tubular member and a modular seal member. The modular seal member can be configured to radially span a lumen of the tubular member and can be removably and replaceably matable to a portion of the tubular member. The access device can also include a plurality of access ports, each of which can be configured to mate with the modular seal member at a respective desired location.

Methods and devices create an intestinal braking effect, are non-invasive or minimally invasive, and may be reversible. These methods and devices may be accomplished via stabilized implantable systems and ingestible pills. In one aspect, a method of inducing satiety includes implanting an implant within a lumen of a gastrointestinal tract and retaining a portion of chyme that flows by the implant within a body of the implant. The method further involves re-releasing the retained chyme from the implant into the gastrointestinal tract at a predetermined rate slower than a rate caused by natural peristalsis.

Methods and devices are provided for providing access through tissue to a surgical site. A surgical access device can be configured to be positioned in tissue to provide access through a working channel of the access device to a body cavity underlying the tissue. The access device can include a sealing element positioned at least partially within the working channel. The sealing element can be formed of a puncturable self-sealing material such as a gel and/or a foam configured to provide a channel seal that seals the working channel when no instrument is inserted through the sealing element and configured to provide an instrument seal that provides a seal around one or more surgical instruments inserted through the sealing element.

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 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, the implantable system comprises a device delivering a therapeutic substance to a target location within the gastrointestinal tract of a patient in order to initiate an intestinal braking effect which would promote sensations of satiety and stimulate excess weight loss for the patient.

A staple cartridge for use with a stapling device that has an actuator that is selectively actuatable in an axial direction and an anvil portion that is selectively movable between open and closed positions is disclosed. Various embodiments of the present invention include a cartridge body that movably supports first and second staple drivers. The staple drivers each support a staple thereon and serve to drive the staples into forming contact with the anvil upon actuation by the actuator. The various embodiments of the present invention enable the final formed heights of the staples to be varied so as to apply various clamping forces and pressures to soft tissue captured within the staples. In at least one embodiment, the staples can include crowns formed thereon which can be utilized to adjust or control the clamping force and/or pressure applied by the staples.
