    摘要: An implantable prosthesis and device and method for loading and delivering the implantable prosthesis to a trocar cannula. The implantable prosthesis includes a body portion sufficient to extend across and occlude a defect opening and a semi-rigid ring for supporting the body portion. The implantable prosthesis may be provided with a sufficient hoop strength to prevent the body portion from collapsing into the defect opening. A loading and delivery tool includes a main body with a lumen sized to collapse the implantable prosthesis. An elongated shaft is rotatable to wind the implant into a slender configuration and axially movable to advance the rolled-up implant into the trocar cannula. A cartridge extends from the main body and holds the implant in a normal expanded configuration.

    摘要: An apparatus for delivery of a fluid is disclosed. The apparatus includes a syringe pump with a plunger, an electronic control element which releases at least one electric charge at predetermined time intervals, a shape memory element with a contractible length decreasing from an uncharged length to a charged length, and a driving mechanism connected to both the shape memory element and the plunger so that the change in length of the shape memory element causes the driving mechanism to provide an activating force to move the plunger and force the expulsion of the fluid from the syringe pump's chamber. As the apparatus according to the present invention can be manufactured as a disposable unit, the problems associated with reusable syringe pumps are avoided.

    摘要: An article treatment system which provides improved solution mixing and concentration uniformity. The treatment system includes a container, a closure and a channel for guiding fluid flow. The treatment system is especially advantageous for use with effervescent tablets and for use in treating contact lenses. Cleaning and disinfecting of articles is improved by use of a tubular channel which guides upwardly gas and other components released from an effervescent tablet which is located at the bottom of the treatment container. The upward central flow through the channel induces a downward flow between the container walls, the exterior walls of the channel, and the article-retaining means and towards the bottom of the container.

    摘要: Implantable therapy systems are disclosed for the local and controlled delivery of a biologically active factor to the brain, spinal cord and other target regions of a subject suffering from a debilitating condition. The method of the invention involves surgically exposing an insertion site, generally located above a predetermined treatment site (12), in a patient. A cannula (20), having an obturator (30) or dilator (104) positioned therein, is inserted at the insertion site, defining a pathway to the treatment site. In some instances, the cannula can be inserted along the path of a guidewire (102) previously positioned at the treatment site. The cannula (20) is preferably a low friction polymeric material such as polytetrafluoroethylene. The cannula (20) generally has an open proximal end for receiving the obturator (30) or dilator (104), and an open distal end, preferably a tapered end, for delivery of neurologically active factors to the treatment site (12). The obturator (30) is then removed from the cannula (20), and a biocompatible tethered vehicle (40) containing a biologically active material is inserted into the cannula along the passageway. A pusher can be inserted within the cannula, behind the vehicle (40), to position the proximal end of the vehicle at the distal end of the cannula (20b). Once the vehicle (40) is positioned near the distal end of the cannula (20), the cannula is removed from the passageway, followed by the pusher, leaving the vehicle (40) positioned at the treatment site (12).
