Patent number: 5464392Abstract: An infusion system for administering multiple infusates at individually programmable rates, volumes, and sequences in any order from any one or more of plural fluid input ports through a patient output port and into the circulatory system of a patient. Infusates may be either continuously or time sequentially administered, and infusates may be either intermittently administered at selectively regular intervals or in time overlap to administer a dilution. Various error conditions are automatically detected and alarms generated in the event of conflicts between infusates, to identify times of no infusions, and to identify system malfunctions. The system is selectively operable, among others, in a priming mode, a maintenance mode, a normal-on mode, and a manual override mode, The system is operative to adapt actual to desired flow rates in normal operation. All fluids flow through a unitary disposable cassette without making any other system contact.Type: GrantFiled: March 7, 1994Date of Patent: November 7, 1995Assignee: Abbott LaboratoriesInventors: Paul Epstein, Harry Petschek, Eric LaWhite, Clair Strohl, Henry Coyne, Edward Kaleskas, George Adaniva

Patent number: 5281231Abstract: Method and apparatus for fracturing hard deposits such as urinary and biliary stones and atherosclerotic plaque in the human body. A flexible guide having a hard mass capping an end is adapted for insertion through a fluid passage in a living body. An energy source creates a rapid vapor expansion adjacent to the cap causing it to undergo a pulse like movement, imparting a high-velocity impulse to an adjacent deposit, thereby fracturing it. The energy source may be a laser with a fiber optic delivery system in the guide terminating adjacent to the cap to cause vaporization of the mass cap to create the vapor expansion. The energy source may be a spark generator with a conductor associated with the guide to deliver a fluid vaporizing spark adjacent to the mass cap. Other forms of rapid energy delivery such as chemical detonations or ballistic impact may also be applicable.Type: GrantFiled: January 21, 1992Date of Patent: January 25, 1994Assignees: Physical Sciences, Inc., The General Hospital Corp.Inventors: David I. Rosen, Harry Petschek, Stephen P. Drexler, Krishna M. Bhatta
