Assignee:

Medrad, Inc. - Indianola PA
International Classification:

A61M 3700
US Classification:

604131, 604 30, 604 43, 604284, 604533, 604256
Abstract:

A fluid delivery system for delivery of an injection fluid to a patient generally includes a pump system to pressurize the injection fluid, a patient interface in removable fluid connection with the pump system, and a connector in fluid connection between the pump system and the patient interface. The pump system is connected to an inlet of the connector, and the patient interface is removably connected to an outlet of the connector. The connector includes a sealing member at least partly disposed within a housing of the connector that is biased to close the outlet when the patient interface is removed.

US Patent:

6866654, Mar 15, 2005
Filed:

Sep 6, 2002
Appl. No.:

10/237139
Inventors:

Gerald W. Callan - Greensburg PA, US
Luis A. Pedraza - West Roxbury MA, US
Jennie Kwo - Cambridge MA, US
Christopher T. Zirps - Sharon MA, US
Roderick H. Beaulieu - Cumberland RI, US
Assignee:

Medrad, Inc. - Indianola PA
International Classification:

A61M005/00
US Classification:

604247, 604246
Abstract:

A pressure isolation mechanism for use in a medical procedure includes a lumen, an isolation port in fluid connection with the lumen, and a valve having a first state and a second state. The first state occurs when the lumen and the isolation port are connected. The second state occurs when the lumen and the isolation port are disconnected. The lumen remains open for flow of fluid therethrough in the first state and in the second state. The valve is preferably spring-biased in the first state and is switchable to the second state when fluid pressure in the lumen reaches a predetermined pressure level. Alternately, an actuator can control the state of the valve. A pressure transducer can be in fluid connection with the isolation port of the pressure isolation mechanism. A fluid delivery system includes a syringe and a pressure isolation mechanism as described above.

US Patent:

6972001, Dec 6, 2005
Filed:

Mar 1, 2004
Appl. No.:

10/790299
Inventors:

Michael F. Emig - Pittsburgh PA, US

International Classification:

A61M037/00
US Classification:

604131, 604533, 604151, 604246, 604247, 604256, 604257, 604258, 128DIG 1
Abstract:

A fluid delivery system for delivery of an injection fluid to a patient generally includes a first pump system, a second pump system, a patient interface in removable fluid connection with the first and second pump systems, and a fluid path in fluid connection between the first and second pump systems and the patient interface. The fluid path preferably includes a housing member defining a first inlet, a second inlet and an outlet. The first and second pump systems are placed in fluid connection with the respective first and second inlets of the housing member and the patient interface is placed in removable fluid connection with the outlet of the housing member. A first check valve is in fluid connection between an outlet of the first pump system and the first inlet of the housing member, and a second check valve is in fluid connection between an outlet of the second pump system and the second inlet of the housing member.

Assignee:

Medrad, Inc. - Indianola PA
International Classification:

A61M 31/00
US Classification:

604 65, 604131, 600432
Abstract:

An injector system includes a powered injector, a pressurizing chamber in operative connection with the powered injector, a fluid path in fluid connection with the pressurizing chamber, and a manual control in fluid connection with the fluid path. The manual control includes at least one actuator for controlling the injector through application of force by an operator. The actuator provides tactile feedback of pressure in the fluid path to the operator via a fluid connection with the fluid path. An injection system for use in angiography includes a source of saline, a pump in fluid connection with the source of saline to pressurize the saline, a saline valve in fluid connection via a first port thereof with an outlet of the pump, a first connector in fluid connection with a second port of the saline valve, a source of contrast, a contrast valve in fluid connection with the source of contrast via a first port of the contrast valve, a powered injector in fluid connection with a second port of the contrast valve, a second connector in fluid connection with a third port of the contrast valve, and a pressure isolation mechanism.
