摘要:
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.

An implantable restriction system having an antenna capable of being readily and predictably movable to achieve a desired orientation that is effective to communicate with an external device is provided. The antenna can be movably coupled to a housing such that the antenna can float and/or move freely with respect to the housing. The housing can be part of a gimbal element or another component of the system. The antenna can include a weight or a magnetic element to help it achieve the desired orientation. Methods for transcutaneously communicating with an implantable restriction device are also provided.

A single handed articulating blunt dissector/gastric band application device includes a support shaft connecting a handle at a first end of the device to an articulating assembly at a second end of the device. The handle includes an actuation mechanism linked to the articulating assembly for controlling movement thereof. The second end includes a proximal end and a distal end, wherein the distal end includes a blunt distal tip shaped and dimensioned for dissecting tissue without unduly causing trauma to the tissue. The second end also includes a suture grasping notch shaped and dimensioned for engaging and pulling a gastric band.

A fastener is used during endoscopic procedures in which a suture is used in creating a predefined pouch through tissue apposition within the stomach. The fastener includes a fastener body having a tissue anchor for selectively securing the fastener body to tissue. The fastener body also includes a connection aperture shaped and dimensioned for passage of a suture therethrough.

Methods and devices for illuminating a body cavity or an internal region of a body are disclosed. In one aspect, a percutaneous illumination device for illuminating a body cavity includes an elongate member with an illumination source, and two support members disposed on the elongate member that are adapted to be positioned on opposite sides of a tissue surface for stabilizing the device. Variations on such an illumination device, kits that include such devices, and methods of utilizing such devices are all described within the present application.

Endoscopic devices methods and devices are provided for attaching opposed walls of tissue. The methods and devices can be used to deliver a plurality of fasteners to opposed tissues, and suture extending through the fasteners can be used to pull the tissues together. The suture can be pre-woven through the fasteners, thus allowing for a quick and simply deployment. While the various methods and devices disclosed herein can be used in a variety of procedures, in certain exemplary embodiments the methods and devices are used to pull together opposed walls of the stomach to form a stomach pouch within the stomach which reduces the rate of gastric emptying.
