Patent number: 11129934Abstract: A pressure jacket for use with a fluid injector includes a barrel having a distal end, a proximal end, and a sidewall extending between the distal end and the proximal end along a longitudinal axis. The pressure jacket includes at least one engagement member protruding from a terminal portion of the proximal end of the barrel in a proximal direction along the longitudinal axis. The at least one engagement member tapers axially in a direction from the distal end toward the proximal end of the barrel. The at least one engagement member engages with a locking mechanism on the fluid injector to releasably lock the pressure jacket with the fluid injector. A taper of the at least one engagement member rotationally guides the barrel into self-alignment with the locking mechanism and axially ejects the barrel upon rotation of the barrel about the longitudinal axis.Type: GrantFiled: October 28, 2015Date of Patent: September 28, 2021Assignee: BAYER HEALTHCARE LLCInventors: Kevin P. Cowan, Barry L. Tucker, Arthur E. Uber, III, Edward J. Rhinehart, Michael A. Spohn, James R. Neill, Glen P. Williams

Patent number: 10512720Abstract: A syringe includes a barrel having a distal end, a proximal end, and a sidewall extending therebetween along a longitudinal axis. At least one engagement member protrudes from a terminal portion of the sidewall in a proximal direction along the longitudinal axis. The at least one engagement member tapers axially in a direction from the distal end toward the proximal end. The at least one engagement member is configured for engagement with a locking mechanism of a fluid injector to releasably lock the syringe with the fluid injector. A taper of the at least one engagement member is configured to rotationally guide the syringe into alignment with the locking mechanism and axially eject the syringe upon rotation of the syringe. The locking mechanism operatively engages the at least one engagement member regardless of an orientation of the syringe about the longitudinal axis relative to the injector.Type: GrantFiled: November 30, 2015Date of Patent: December 24, 2019Assignee: BAYER HEALTHCARE LLCInventors: Kevin P. Cowan, Barry L. Tucker, Arthur E. Uber, III, Edward J. Rhinehart, James R. Neill, Glen P. Williams, Michael A. Spohn

Publication number: 20150273137Abstract: The continuous fluid delivery systems includes a fluid pumping device comprising a pump housing comprising a base member with a plurality of inlet ports and at least one outlet port and at least two pairs of opposing pistons movably associated with the housing. Each pair of opposing pistons at least in part defines a respective pumping chamber of the fluid pumping device. The pistons in each pair of opposing pistons may be independently controlled such that any one of the plurality of inlet ports or the at least one outlet port is independently selectable to be in fluid communication with one of the respective pumping chambers. A drive system may be interfaced with the respective pistons to at least reciprocally operate the pistons relative to the base member. The pump housing and the at least two pairs of opposing pistons may comprise a disposable unit.Type: ApplicationFiled: June 12, 2015Publication date: October 1, 2015Inventors: CHRISTOPHER D. CAPONE, JAMES R. NEILL, JASON L. BAZALA, ROGER V. DELONGA, RICHARD A. SEMAN

Patent number: 8096316Abstract: A valve system for use in a system including a first source of a first pressurized fluid and a second source of a second pressurized fluid includes a valve housing including a first inlet port adapted to be placed in fluid connection with the first source, a second inlet port adapted to be placed in fluid connection with the second source and an outlet port. The valve system further includes a backflow prevention system to prevent flow of the first pressurized fluid through the second inlet and to prevent flow of the second pressurized fluid through the first inlet port. The valve system is adapted to provide a fluid path between at least the first inlet port and the outlet port to enable fluid to be drawn from the outlet port to the first inlet port. Several of the valve systems of the present invention provide for flow from the first inlet port to the outlet port and concurrent flow from the second inlet port to the outlet port.Type: GrantFiled: October 27, 2008Date of Patent: January 17, 2012Assignee: Medrad, Inc.Inventors: Mark Trocki, David M. Reilly, James R. Neill, Christopher D. Capone

Patent number: 7691085Abstract: A syringe interface includes a top opening into which a syringe can be loaded, a first retaining member positioned on one side of the opening and a second retaining member positioned on a second side of the opening. The first retaining member and the second retaining member abut a forward facing abutment surface of a syringe flange on the syringe generally symmetrically. The syringe interface further includes a cradle, at least one engagement member to abut a forward facing abutment surface of a syringe flange, and a carriage slidably disposed within the cradle. The carriage includes a connector to form a releasable connection with a plunger or plunger extension of the syringe and a drive member of the injector. The connector includes a plurality of flexing capture members that flex radially outward to connect to a flange on the rear of the plunger or plunger extension of the syringe when the carriage is moved forward within the syringe interface.Type: GrantFiled: November 15, 2002Date of Patent: April 6, 2010Assignee: Medrad, Inc.Inventors: James Albert Dedig, Frank A. Lazzaro, Kevin P. Cowan, Mark W. Hitchins, Charles J. Mutschler, James R. Neill
