Abstract: A self-covering element for covering a pipe joint comprising of a deformable, hollow insulating element having a first portion and a second portion attached at an angle to one another. A longitudinal slit runs the length of the first and second portions, and a pressure sensitive adhesive with a removable release film is adhered to the longitudinal slit. The deformable insulating element allows for the entry of the pipe joint through the longitudinal slit, and surrounds the pipe joint. The pressure sensitive adhesive then seals the longitudinal slit and the pipe joint into the hollow cavity once the release film is removed.

Abstract: Disclosed herewithin is a method of fabricating a stent which involves processing a tubular member whereby no connection points to join the edges of a flat pattern are necessary. The method includes the steps of a) removing contaminates from a tubular member, b) coating the outside surface of the tubular member with a photo-sensitive resist material, c) placing the tubular member in an apparatus designed to simultaneously rotate the tubular member while passing a specially configured photographic frame negative between a UV light source and the tubular member, thereby exposing a specified pattern of UV light to the resist coated tubular member, d) exposing the outside surface of the tubular member to a photoresist developer for a specified period of time, e) rinsing the excess developer and uncured resist from the outside surface of the tubular member, and f) treating the tubular member with an electro-chemical process to remove uncovered metal. This process can lend itself to virtually an unlimited number of stent designs and configurations. By modifying the photographic frame negative, the same process can be employed to fabricate various stent designs from a tubular structure.

Le procédé amélioré de la présente invention, qui permet de former un dispositif de libération prolongée à base de polymère, consiste à former une solution de polymère/principe actif en mélangeant un polymère, une phase continue et un principe actif. La phase continue peut comprendre un ou plusieurs solvants polymériques, un mélange solvant polymérique/non solvant polymérique, ou un mélange solvant polymérique/non solvant de principe actif. Lorsque la phase continue comprend un solvant polymérique/non solvant de principe actif, le principe actif peut également être présent sous forme de microparticule plutôt que sous forme de solution. On crée alors une matrice solide polymère/principe actif en retirant la phase continue de la solution polymère/principe actif.
