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: A medical device includes a handle and a shaft having a working channel. A biopsy port at the exterior of the handle provides a path for instruments leading to the working channel. A conduit that runs through the handle for supplying fluids is also provided a path to the working channel. As compared between the path from the biopsy port to the working channel and the path from the conduit to the working channel, the path from the biopsy port to the working channel is the more direct path of the two.

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.

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: 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: A cryogenic tissue ablation instrument includes an elongate flexible body with a proximal supply port for coupling with a pressurized coolant, a supply lumen in communication with the proximal supply port, and an expandable balloon carried on the elongate body. A dispersion member coupled to the elongate body has an interior lumen in communication with the supply lumen, the dispersion member having one or more coolant dispersion apertures sized and located such that a pressurized flowable coolant will enter the balloon interior in the form of a liquid spray that contacts and provides substantially uniform cooling of the balloon.
