摘要:
A design for a suture for use in suture appositioning techniques, and a method for use are disclosed. In one embodiment the suture may comprise a hollow length having a wall forming a lumen, which may serve as a conduit through which fluid may be pumped and discharged through a plurality of perforations in the wall. In another embodiment the suture may comprise a plurality of suture members connected by a connecting member. In one embodiment of a method disclosed, a suture having a hollow length having a wall forming a lumen, with a plurality of perforations in the wall, may be placed in a stitching procedure to apposition tissues, and a fluid such as an adhesive, adhesive activating agent or drug may be pumped through the lumen and discharged out the perforations for various beneficial effects.

Provided is a two-piece anastomosis fastener that can be used to join two tissue sections together in accordance with Natural Orifice Transendoscopic Surgery (NOTES). The fastener may be releasably attached to a fastener applying instrument for delivery in accordance with such procedures. The fastener includes a first member and a second member, where the clamp members are operably configured to fasten together to clamp and hold tissue, such as gastric tissue, in juxtaposition to establish an anastomosis. The first clamp member and the second clamp member are coupled with an adhesive.

A material comprising a matrix or a buttress is impregnated with an adhesive initiator and is used with a surgical stapling device and an adhesive. The tissue and material are stapled together, and a knife in the surgical stapling device cuts the tissue and the material. The adhesive is applied across the cut and sets up or polymerizes to seals the cut when the adhesive contacts the adhesive initiator. The surgical stapling device can place the staples in a linear, arcuate, or circular array, and can anastomose luminal tissue. The methods of use can include stapling luminal tissue end to end, stapling two portions of material onto ether side of tissue, and stapling two portions of tissue onto a portion of material. Additionally, a portion of adhesive filed material can be stapled onto one side of portion of tissue and the adhesive initiator impregnated material can be stapled onto the other. Cutting the material and tissue provides a path for the adhesive across the cut, and catalyzes the adhesive from contact with the adhesive initiator.

摘要:
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 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.

Devices and methods for modifying stomach volume include the formation of intragastric slots for wrapping one or more portions of the fundus therethrough with minimal interference with nerves and vasculature flow. Intragastric space occupying devices expand with environmental changes brought about by natural conditions inherent to the digestive cycle such as with changes in pH. Extragastric volume occupying balloons are placed into folded stomach sections. The balloons are fluidly coupled to external gastric filling devices. In yet another set of embodiments, methods and devices provide adjustable gastric volume reduction fundal wraps. In one embodiment, a device is placed in the fundus for Nissen fundoplication and permits postoperative adjustment to reach desired weight loss. Intragastric and extragastric balloons are optionally incorporated.
