Abstract: An oral expansion device comprises a first body, main body and a second body wherein the first body and second body are attached to a body and a first tube and a second tube wherein the first tube and second tube having one end attached to the body and having a second end attached to an inflation device. The first tube can be attached internally to the first cavity to the inflate or deflate it and the second tube can be attached internally to the second cavity to inflate or deflate it. The body is manufactured from a flexible material. The first cavity and the second cavity can be manufactured from an inflatable material. The first cavity is an oval and the second cavity is a rectangular shape. The body has a 35-degree bend wherein the second cavity is centered on the 35-degree bend and the body can have two depressions on its sides.

Abstract: Composite fiber reinforced balloons for medical devices prepared by applying a web of fibers to the exterior of a preformed underlying balloon and encasing the web with a matrix material to form a composite balloon. The fiber web is applied to at least the cone portion of the underlying balloon form. Either the cone portion of the underlying balloon form, or the web fibers applied to said cone portion, or both, have a friction-enhancing material coated thereon.

Abstract: Instruments for thermally-mediated treatment of a patient's lower esophageal sphincter (LES) to induce an injury healing response to thereby populate the extracellular compartment of walls of the LES with collagen matrices to altere the biomechanics of the LES to provide an increased intra-esophageal pressure for preventing acid reflux. A preferred embodiment is a bougie-type device for trans-esophageal introduction that carries conductive electrodes for delivering Rf energy to walls of the LES (i) to induce the injury healing response or (ii) to “model” collagenous tissues of the LES by shrinking collagen fibers therein. Typically, an Rf source is connected to at least one conductive electrode that may be operated in a mono-polar or bi-polar fashion. A sensor array of individual sensors is provided in the working end.

Abstract: A part that can be introduced and/or implanted in the body, in body parts, or in body cavities, made of nonmetallic material or having a nonmetallic surface is designed such that infections associated with the use of parts of this type are reduced or entirely eliminated. This is achieved due to the fact that the entire surface of this part or parts or, depending on the effect, partial areas of this part or parts, that are nevertheless not in geometric contact, is/are furnished with a metallization (6). It is also possible that the material at least in the area of its exterior surface (17) contains metallic particles (18) in powder or granular form made of a metal having an oligodynamic effect, and that the most exterior metallic particles (18) are uncovered at least partially at the surface.
