Patent number: 7591797Abstract: A flexible fluid filled actuator has an elastic bladder and a guide surrounding the bladder. The guide has asymmetrical elastic properties. When the bladder is inflated the guide directs the bladder to expand preferentially in a selected direction or directions. The actuator has utility in the traction and/or unloading of portions of the body. A fluid-filled traction apparatus is disclosed which has particular advantages in spinal unloading.Type: GrantFiled: July 19, 2004Date of Patent: September 22, 2009Assignee: Pneu Medex Inc.Inventors: Greg Hakonson, Christopher Denny, Scott Phillips, Mark Foster

Publication number: 20060167405Abstract: A bodily fluid space entry detection system includes electrical contacts in non-conducting relationship and associated with a needle cannula. Entry of the distal, sharp tip of the cannula into a bodily fluid space such as a blood vessel or epidural space allows bodily fluid such as blood or spinal fluid to make a conduction path between the contacts which, in turn, causes an alert source to be energized to indicate entry into the bodily fluid space. The alert source could be an LED and/or a buzzer.Type: ApplicationFiled: December 13, 2004Publication date: July 27, 2006Applicant: MEDEX, INC.Inventors: Alan KING, James MUSKATELLO

Publication number: 20050187532Abstract: A reservoir (10, 26, 80, 126, 226, 380) includes a rigid wall (12, 28, 82, 128, 228, 382), a flexible membrane (14, 34, 134, 234, 334) sealingly secured to the rigid wall (12, 28, 82, 128, 228, 382) to define a variable volume chamber (18, 38, 138, 238, 338), and inlet (40, 140, 240, 340) and exit (42, 142, 242, 342) ports in fluid communication with the chamber (18, 38, 138, 238, 338). A drive surface (24, 50, 150, 250, 350) engages the membrane (14, 34, 134, 234, 334) to position it adjacent the rigid wall (12, 28, 82, 128, 228, 382) to define a minimum volume position. The drive surface (24, 50, 150, 250, 350) may be moved so that the membrane (14, 34, 134, 234, 334) flexes out of the minimum volume position to an expanded volume position. The membrane (14, 34, 134, 234, 334) may be coupled to the drive surface (24, 50, 150, 250, 350) or be uncoupled from the drive surface (24, 50, 150, 250, 350).Type: ApplicationFiled: February 24, 2004Publication date: August 25, 2005Applicant: Medex, Inc.Inventors: Bernd Thurau, Robert Herz, Angela Crall, Dale Gallogly
