Filed:

Aug 18, 2006

Appl. No.:

11/465612

Inventors:

Jason D. Toman - Swissvale PA, US
Douglas A. Staunton - Kalamazoo MI, US

Assignee:

Stryker Corporation - Kalamazoo MI

International Classification:

A61M 5/00
A61M 5/20

US Classification:

604247, 604173

Abstract:

An infusion assembly for delivering therapeutic fluid to plural body sites is provided. The assembly includes a positive displacement pump that discharges the therapeutic fluid. The assembly also includes a flow regulator valve including a valve housing that defines a pressure chamber, an inlet bore that opens into the pressure chamber, and first and second outlet passageways. The first and second outlet passageways extend, respectively, from separate first and second outlet openings to a first catheter and a second catheter through which the therapeutic fluid is directed to the body sites. A controller cyclically regulates the operation of the pump so that, in a first phase of each cycle, the pump is actuated so as to cause a fluid pulse to be presented through the inlet bore of the valve housing to the diaphragm and in a second phase of each cycle, the pump is not actuated.

International Classification:

A61M 1/00

US Classification:

604151, 604 65

Abstract:

A fluid delivery system is provided for delivering fluid to a patient. The system comprises a reservoir for storing the fluid to be delivered to the patient and a fluid discharge device operatively coupled to the reservoir for delivering the fluid from the reservoir to the patient. A controller is configured to operate the fluid discharge device. An input device is in electronic communication with the controller and configured for setting at least one operating parameter of the system. The controller operates the fluid discharge device based on the at least one operating parameter and locks the system after the at least one operating parameter is set such that the at least one operating parameter is unable to be modified. A display is in electronic communication with the controller to at least periodically display a code for resetting the at least one operating parameter. The code is altered at least once during use.

Assignee:

Stryker Corporation - Kalamazoo MI

International Classification:

A61M 5/00

US Classification:

604247, 604173, 251331, 1375124

Abstract:

An apparatus for use in delivering pain medication to separate locations from a single source of pressurized medication includes a valve housing, a cap, and a flexible diaphragm. The valve housing includes a first end and a second end and an inlet passage. The first end includes first and second outlet orifices. The cap has a closed end and an open end and is removably coupled to the valve housing at the open end. The flexible diaphragm is coupled between the cap and the valve housing and is movable from a closed position to an open position. The flexible diaphragm seals a pressure chamber from the first and second outlet orifices when in the closed position and opens the first and second outlet orifices to the pressure chamber when in the open position.

International Classification:

A61M031/00
A61M001/00

US Classification:

604/500000, 604/151000

Abstract:

A medication delivery system includes a reservoir for storing a supply of medication and a pump assembly coupled to the reservoir. The pump assembly has a pump inlet and a pump outlet and is controllable to provide a flow of medication in the form of a series of pulses. The pump outlet is subdivided into a plurality of legs. A controller is coupled to the pump assembly for controlling the pump assembly and receives a desired flow of medication and responsively controls the pump assembly to provide a series of pulses of medication to provide the desired flow of medication. The series of pulses are determined to provide an outlet pressure at the pump outlet adapted to reduce an effect of any differential pressure between the legs.

US Classification:

604/524000

Abstract:

A catheter for delivering medication from a fluid source to an anatomical site of a patient and a method of manufacturing the same are provided. The catheter comprises an elongated tube extending between an open proximal end and a closed distal end. The elongated tube includes a catheter wall having an inner surface that bounds a lumen for conveying the fluid from the fluid source. A plurality of openings are defined in the catheter wall to discharge the fluid from the lumen to the anatomical site. A reinforcing coil is disposed within the lumen to improve fluid delivery and provide kink resistance to the catheter. The reinforcing coil has spaced convolutions in an unstretched state. An annular flow space is defined between the reinforcing coil and the inner surface of the catheter wall. As a result, fluid can travel both through an inner lumen of the reinforcing coil and between the spaced convolutions to the annular flow space or the fluid can travel directly through the annular flow space to reach the openings.
