Patent CA-2430977-A1 (CA)
Title: Antimicrobial release system
Inventor: MITCHNICK MARK ALAN
IPC: A61L31/16
Filed: 2003-06-04
Abstract: The present invention relates to medical devices that are inserted or implanted into patients and that have antimicrobial coatings that release free radicals into the vicinity of the device. These devices may have coatings that alter their rate of flow release or elution release of an antibacterial agent from a coating on the device upon external stimulation. The coating should therefore be responsive to external control such as by heating, external RF stimulus, sonic control, visible or ultraviolet light exposure and the like.  By having control of the release rate, and in some structures without invasion of the patient by mechanical means in addition to the device itself the release rate can be in response to need at the implant site. The class of compounds to be released are free radical generating or initiating compounds, or compounds that release free radicals upon immersion or stimulation, the free radicals acting as the antimicrobial agent.

Title: Distal targeting of locking screws in intramedullary nails
Inventor: GOVARI ASSAF
IPC: A61B17/58
Filed: 2003-07-17
Abstract: In a distal targeting system a hand-held location pad is integral with a guide sec- tion for a drill or similar surgical instrument, and has a plurality of magnetic field gen- erators. A sensor, such as a wireless sensor, having a plurality of field transponders, is disposed in an orthopedic appliance, such as an intramedullary nail. The sensor is capa- ble of detecting and discriminating the strength and direction of the different fields generated by the field generators. Control circuitry, preferably located in the location pad is responsive to a signal of the sensor, and determines the displacement and relative directions of an axis of the guide section, and a bore in the orthopedic appliance. A screen display and optional speaker in the location pad provide an operator- perceptible indication that enables the operator to adjust the position of the guide section so as to align its position and direction with the bore.

Title: Membrane-electrode assembly for a self-humidifying fuel cell
Inventor: BIEGERT HUBERTUS
IPC: H01M8/04119
Filed: 2002-09-14
Abstract: The invention relates to a membrane-electrode assembly for a self-humidifying fuel cell. The electrodes of the inventive MEA consist of a catalyst layer that is applied to the membrane side, a microporous electrode layer that borders said catalyst layer and a macroporous electrode layer immediately adjacent to said microporous layer. The latter comprises platelet-shaped graphite on the cathode side and on the anode side carbon black particles with a rough surface and the capacity to store water. As a result of the construction and the morphology of the respective electrode, the co-operation between the two electrodes of the MEA composite and their adaptation to one another, a mass flow is formed from the cathode to the anode, said flow favouring the back-diffusion of the reaction water through the electrolyte, thus guaranteeing sufficient humidification of the electrolyte.

Title: Footwear with bladder type stabilizer
Inventor: POTTER DANIEL R
IPC: A43B13/14
Filed: 2002-09-18
Abstract: A stability device that increases foot security on the footbed of a shoe, provides lateral or medial stability, shock dampening, and optimizes flexibility. The stability device includes a resilient bladder insert having a horizontal sole portion underneath a wearer's foot, and a vertical foot portion positioned to a lateral or medial side edge of a wearer's foot. The horizontal sole portion and the vertical foot portion are in fluid communication and are proximal the first or fifth metatarsal regions of the foot. The stability device can be generally L-shaped to cradles a portion of the foot. A compression force of a foot landing on the horizontal sole porti on causes an increase in fluid pressure in the foot portion which stiffens the vertical foot portion forming a bumper-like wall for absorbing side impactin g force from the foot and serving to keep the foot on the footbed. The stabili ty device can include a plurality of finger-shaped elements. The finger-shaped elements can have a stem portion and a bulbous portion, and can expand in on e direction and contract in another in response to an increase in fluid pressu re therein. The finger-shaped elements can be connected to straps or a vamp tha t extends over the top of a wearer's foot, the straps and/or vamp being substantially inelastic ina direction perpendicular to a longitudinal direction of a wearer's foot, such that, contraction of the finger-shaped elements tightens the straps and/or vamp on the wearer's foot. The finger- shaped elements may encircle the top of the foot and expand down onto the fo ot due to an increase in fluid pressure therein .

Title: Carbon dioxide foamed fluids
Inventor: POPE TIMOTHY
IPC: C09K8/70
Filed: 2004-06-04
Abstract: An aqueous viscoelastic surfactant (VES) fluid foamed or energized with carbon dioxide, in which the VES is more compatible with the carbon dioxide, is made by the addition of one or more than one synergistic co-surfactant. The synergist co-surfactant includes quaternary amines and ethoxylated carboxylates having a hydrophobic chain shorter than the hydrophobic chain of the VES. Improved compatibility is evidenced for a given surfactant concentration either by formation and maintenance of a foam under conditions at which the foam could not otherwise have been formed or maintained, or by either higher viscosity of the foamed fluid at a given temperature or longer foam life at a given temperature or a higher temperature at which useful fluid viscosity can be generated or maintained for a useful time. The aqueous carbon dioxide foamed fluids may be used in acidizing, acid fracturing, gravel packing, diversion, and well cleanout.
