Patent number: 7258681Abstract: An automated fluid control system for controlling fluid flow between a catheter, a saline supply, a contrast supply and an injector is disclosed. Pinch valves are provided in the saline input and output lines and contrast input and output lines. A controller is linked to the pinch valves to sequentially open and close the pinch valves during functions which include contrast injection and saline injection.Type: GrantFiled: October 2, 2002Date of Patent: August 21, 2007Assignee: Scimed Life Systems, Inc.Inventor: Eric Houde

Patent number: 7044933Abstract: A fluid injection apparatus and method of injecting fluid are disclosed. The apparatus includes a control syringe electrically connected to a power-actuated syringe. A sensor is provided proximate the control syringe to monitor the position of the plunger therein, with a signal representative of plunger position then being communicated to a processor for calculation of a corresponding control signal. The control signal is received by an actuator of the power-actuated syringe to move the plunger of the power-actuated syringe in a manner related to movement of the control syringe. The control syringe is provided with a feedback device to provide the operator with an indication as to the pressure of the fluid being injected into a patient.Type: GrantFiled: March 1, 2001Date of Patent: May 16, 2006Assignee: Scimed Life Systems, Inc.Inventors: Mark H. VanDiver, Colin P. Hart, Kevin C. Martin, Thomas R. Delcourt, Eric Houde

Patent number: 6976974Abstract: A fluid control apparatus is disclosed for controlling fluid flow between a catheter, an injector, a saline supply, a waste dump and a contrast supply. The apparatus includes a valve stem movable within a cavity disposed in a valve body. The valve stem is movable to a plurality of positions including a contrast position where the valve stem provides communication between the injector and a contrast supply, a saline/waste position where the valve stem provides communication between the injector and a saline/waste line and an injection position where the valve stem provides communication between the injector and an outlet port connected to the catheter.Type: GrantFiled: October 23, 2002Date of Patent: December 20, 2005Assignee: SciMed Life Systems, Inc.Inventors: Eric Houde, Mark Van Diver, Scott Diamond

Publication number: 20050171502Abstract: A port for implantation within a body, comprises a housing having a proximal surface, a distal surface and a side surface wherein, when the port is implanted within a body in a desired orientation, the proximal surface faces outward toward the skin, the distal surface faces inward away from the skin and the side surface extends between the proximal and distal surfaces and a first well formed within the housing, the first well including a first opening in the proximal surface. A second well is formed in the housing adjacent to the first well and has a second opening formed in the proximal surface. First and second outlet openings formed on the side surface of the port are in fluid communication with the first and second wells, respectively, and are separated from one another by a distance substantially equal to a distance separating lumens of a dual lumen catheter to which the port is to be connected.Type: ApplicationFiled: January 29, 2004Publication date: August 4, 2005Inventors: Katie Daly, Kristian DiMatteo, Eric Houde

Patent number: 6918893Abstract: A fluid control valve is disclosed which, with a single valve, can manipulate flow between a saline supply, a contrast supply, a waste dump and a catheter. The control valve includes three primary positions including a contrast position where the valve provides communication between an injector and a contrast supply while isolating the saline supply and catheter. The valve also can be moved to a saline/waste position where the valve provides communication between the injector and the saline supply and/or the waste dump while isolating the contrast supply and catheter. The valve also can be moved to an injection position where the valve provides communication between the injector and the catheter. A single valve provides all three functions. The valve also may provide communication between a pressure transducer and catheter during the saline loading, waste dumping and contrast loading functions. The valve also provides protection or isolation of the pressure transducer during injection procedures.Type: GrantFiled: October 2, 2002Date of Patent: July 19, 2005Assignee: SciMed Life Systems, Inc.Inventors: Eric Houde, Mark van Diver, Scott Diamond

Publication number: 20040010229Abstract: A fluid injection system is disclosed. The system is adapted to employ first and second injectors which may sequentially, or simultaneously, inject first and second fluids into a patient via a catheter. The first and second injectors may be power actuated. The actuation of the injectors may be controlled via a controller of the system. The user may be provided with an operator interface module to enable the control of the system to be affected during operation. A separate waste line may be provided to drain the system effectively and efficiently. A pressure sensor may be provided proximate the catheter to reduce pressure signal wave dampening and fluid waste.Type: ApplicationFiled: July 11, 2002Publication date: January 15, 2004Inventors: Eric Houde, Mark VanDiver, Colin P. Hart, Valerie M. Castora, Kathryn M. Albert
