  • Patent number: 6926723
    Abstract: 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 moveable 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.

  • Patent number: 6267772
    Abstract: An implantable prosthesis for occluding the opening of a muscle or tissue defect. The implant is laparoscopically deliverable with a system for loading and delivering the prosthesis through a trocar cannula. The prosthesis includes an implantable material with a body portion sufficient to extend across and occlude a defect opening. Antimigration barbs extend from the implantable material to prevent migration of the prosthesis after implantation. A semi-rigid ring may be attached to the material for supporting the body portion. The barbs may be located on the ring. The implantable prosthesis may be provided with a sufficient hoop strength to prevent the body portion from collapsing into the defect opening.

  • Patent number: 6179826
    Abstract: 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 dibilatating 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).

  • Patent number: 6110151
    Abstract: An inflation device according to the present invention includes a barrel, a piston at least partially disposed within the barrel, and a collar surrounding at least a portion of the barrel. The piston includes a threaded portion. The collar and the barrel are axially movable with respect to one another, with the barrel being biased towards an equilibrium position within the collar by a collar spring. A nut is disposed at least partially within the barrel, the nut including an interior threaded surface and an exterior camming surface. The nut is movable along an axis substantially transverse to the barrel axis, and is biased towards a collar camming surface by a nut spring. When the barrel is in the equilibrium position, the nut is in a locking position in which the interior threaded surface engages the threaded portion of the piston. This prevents free movement of the piston within the barrel.

  • Patent number: 5992309
    Abstract: A device for drying food includes a bowl having a bottom wall and a sidewall terminating in a top edge, a cover removably connected to the top edge of the bowl and a perforated basket disposed in the bowl and rotatable relative thereto coaxially therewith, and a drive assembly coupled to the basket for effecting rotation thereof. The drive assembly includes a linearly reciprocating handle structure with a screw shaft engageable with a nut coupled to the basket for converting the reciprocating movement of the handle structure to rotary motion of the basket.

  • Patent number: 5919167
    Abstract: 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.

  • Patent number: 5891051
    Abstract: A monitor is disclosed for measuring a liquid discharged from a patient's body. A housing defines a cavity having a floor. A substantially rigid wall container is removably positioned within the cavity, the container having a bottom wall portion supported on the floor of the cavity. A transducer is mounted in the floor of the cavity and engages the bottom wall portion of the container. The transducer is periodically engaged to transmit energy through the bottom wall portion and into a pool. The time duration required for the transmitted energy to travel from the transducer means to the upper surface of the pool and back again is determined, and this time duration is converted into a volume of fluid by reference to a look-up table, a mathematical algorithm, or both. The monitor includes an optical sensor to detect the presence of a container in the housing and provides an indication if no container is detected.

  • Patent number: 5810852
    Abstract: An endoscopic intracorporeal suture tying aid allows a suture to be looped around itself multiple times and cinched, enabling a throw of a surgeon's knot to be easily made. The tying aid includes a needle holder connected to a proximal end of a shaft for releasably holding a needle; a hook that slides longitudinally with respect to the beaks; and the shaft being axially rotatable with respect to the hook.

  • Patent number: 5756044
    Abstract: 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.
