    Abstract: A stent deployment device for deploying a stent within a body cavity comprises an endoscope having a protective cap, a flexible stent, a sheath, and a flexible, elongated member. The protective cap is mounted on the distal end of the endoscope providing a protected surface for retaining the stent. The flexible stent is circumferentially compressed over the perimeter of the cap, and the sheath is then releasably wrapped around the stent to hold it in a compressed configuration over the cap. The flexible, elongated member, such as a wire extending through a working channel of the endoscope, is attached to either the sheath directly or to a releasing device for the sheath. After the endoscopic device is inserted in a body cavity, the flexible, elongated member is pulled through the working channel to release the sheath and deploy the stent into a desired body opening in the body cavity. After deployment of the stent, the sheath can be left in the body cavity for subsequent retrieval or retracted through the endoscopic device.

    Abstract: Endoluminally delivered tissue patches and related systems and methods for delivering the tissue patches for treating lesions of the alimentary tract are disclosed. A tissue patch includes a substrate, a tissue implant attached to the substrate, and a protective liner covering at least a portion of the tissue implant. A method includes providing a tissue patch having a tissue implant attached to a substrate and a protective liner covering at least a portion of the tissue implant. The tissue patch is formed into a contracted state and inserted into a lumen containing the lesion. The tissue patch then is positioned in the vicinity of the lesion. After removing the protective liner to reveal the tissue implant, the tissue implant is placed in the lesion.

    Abstract: Disclosed are implantable or insertable medical devices that provide resistance to microbial growth on and in the environment of the device and resistance to microbial adhesion and biofilm formation on the device. In particular, the invention discloses implantable or insertable medical devices that comprise at least one biocompatible matrix polymer region, an antimicrobial agent for providing resistance to microbial growth and a microbial adhesion/biofilm synthesis inhibitor for inhibiting the attachment of microbes and the synthesis and accumulation of biofilm on the surface of the medical device. Also disclosed are methods of manufacturing such devices under conditions that substantially prevent preferential partitioning of any of said bioactive agents to a surface of the biocompatible matrix polymer and substantially prevent chemical modification of said bioactive agents.

    Abstract: A stenting system for insertion into the lumen of a body duct or vessel for delivering a therapeutic agent to a treatment site on the duct or vessel. The stenting system includes an a tubular stent member having a lumen there through to allow the passage of material, an outer membrane attached to the stent at least a portion of which is porous to the therapeutic agent to allow the agent to pass to the treatment site, an inner membrane attached to the stent which is nonporous to the therapeutic agent to prevent the agent from entering the lumen of the stent, and a chamber located between the inner and outer membranes for holding the therapeutic agent. The therapeutic agent in the chamber may diffuse through the porous portion of the membrane and be deposited directly on the body site.

    Abstract: In at least one embodiment, the invention is directed to an endoluminal device comprising a stent and a sleeve. In one embodiment, the endoluminal device is implanted in a portion of the gastrointestinal tract. In some embodiments, the stent has a first region and a second region where the first and second regions provide different levels of radial force. In one embodiment, the first region is made from a plurality of first wires having a first diameter and the second region is made from a plurality of second wires having a second diameter which is smaller than the first diameter. In other embodiments, the endoluminal device has at least one engagement mechanism engaging the stent to the sleeve, the endoluminal device to a body lumen, and any combination thereof. In at least one embodiment, the endoluminal device has a wall with at least one opening therein.

    Abstract: A porous weave of bioabsorbable filaments having an open mesh configuration is formed into an oblate shape having dimensions greater than the esophageal opening and gastric outlet of a stomach. The resulting prosthesis is deployed in the stomach and is of a size to be retained in the proximate portion thereof for exerting pressure on the upper fundus. The prosthesis limits the amount of food that may be held within the stomach, and exerts pressure on the fundus to create a sensation of being full, resulting in weight loss.
