Publication number: 20060149189Abstract: A power injection catheter for high flow rate delivery of fluids. The power injection catheter may include a pressure relief mechanism for preventing overpressurizing within the lumen of the catheter. The pressure relief mechanism may be configured to prevent sudden pressure build-up inside the catheter lumen by absorbing, buffering or releasing pressure inside the lumen during pressure spikes. The power injection catheter may also take the form of a multi-lumen catheter capable of simultaneous infusions of a single fluid through two or more of the lumens in the catheter.Type: ApplicationFiled: January 4, 2005Publication date: July 6, 2006Inventors: Jordan Diamond, Abtihal Raji-Kubba, William Barron, Catherine Breiter

Publication number: 20060060012Abstract: The present invention provides a device that modifies the centrifugal force of a series of weights held at the perimeter of a rotating assembly by creating an acceleration on the weights perpendicular to their circular path of travel in addition to the centripetal force acting on them. By creating an acceleration on each weight perpendicular to its circular path and by timing when to create the acceleration, the net centrifugal force of the weights can be increased along the top of their rotational path and decreased along the bottom of their rotational path thereby producing a sustainable imbalance that can produce a thrust which propels the device in a particular direction. By using numerous weights on the rotating assembly, a smoother continuous force will be produced. In addition, the present invention can be processed, accelerated or decelerated to produce three dimensional controlling force vectors to add stability to its platform.Type: ApplicationFiled: September 23, 2004Publication date: March 23, 2006Inventor: William Barron

Publication number: 20050261664Abstract: A multifunction adaptor for an open-ended catheter that allows placement of the catheter while minimizing the risk of air embolism or blood loss through the open (proximal) end of the catheter body. In one variation, the design allows passage of a standard guidewire for “over-the-guidewire” placement techniques and a connection for catheter flushing using a standard syringe. In another variation, the multifunction adaptor is configured for coupling a tunneler to the proximal end of a catheter.Type: ApplicationFiled: March 8, 2005Publication date: November 24, 2005Inventors: Guy Rome, William Barron, John Evans, Dwight Hibdon, John Zawacki

Publication number: 20050261636Abstract: A valved catheter that allows placement and withdrawal of an accessing device or attachable unit without the risk of air embolism or blood loss. In one variation, the valved catheter includes a catheter tube having a necked portion in its proximal end that forms an integral valve, the necked portion being surrounded by a compression sleeve that biases the valve in a closed position. In another variation, the valved catheter is a dual lumen catheter with a corresponding bifurcating extension for engaging the valves in the catheter in order to establish fluid communication through the catheter.Type: ApplicationFiled: May 3, 2005Publication date: November 24, 2005Inventors: Guy Rome, William Barron, Bret Hamatake
