  • Publication number: 20080091142
    Abstract: An injector system includes a source of injection fluid, a pump device, a fluid path set disposed between the source of injection fluid and the pump device, a fluid control device operatively associated with the fluid path set and a hand held control device for controlling the flow rate of the injection fluid. The hand held control device includes a piston slideably disposed within a chamber and adapted to engage a switch that controls the flow rate of the injection fluid. The fluid control device is adapted to permit purging of air from the fluid path set and to stop flow of the injection fluid to a patient at substantially any pressure or flow rate generated by the pump device for delivering a sharp bolus of the injection fluid to the patient. The fluid control device is preferably part of the fluid path set between the source of injection fluid and the pump device.

  • Publication number: 20070197963
    Abstract: A combined fluid injection and inflation system is disclosed and includes a fluid delivery system including at least one pressurizing device, a fluid path, and a control unit. The fluid path is adapted to connect the pressurizing device to a patient via a catheter including a balloon and inserted in the patient. The control unit is operable to control the fluid delivery system. In operation, the control unit selectively actuates the fluid delivery system to operate in a fluid injection mode or in a balloon inflation mode. In the fluid injection mode the pressurizing device delivers fluid to the fluid path for a fluid injection procedure. In the balloon inflation mode, the pressurizing device delivers fluid to the fluid path for inflating the balloon associated with the catheter. An operator control may be connected to the control unit for controlling the fluid delivery system and may be a handheld device.

  • Publication number: 20070106208
    Abstract: A system for injecting an injectate into patient includes a first pressurizable container for holding the injectate; a patient interface in fluid connection with the first pressurizable container, the patient interface being adapted to pass the injectate into tissue of the patient; a powered injector in operative connection with the first pressurizable container to pressurize the injectate; a controller system in operative connection with powered injector; and a stereotactic localization frame adapted to be placed in operative connection with the patient interface to assist in controlling localization of the patient interface. A system for processing cells (and/or other injectate components) includes a container and a plunger adapted to be slidably positioned within the container. The system includes at least one inlet port through which a fluid can enter the system and at least one effluent port through which an effluent can exit the system.

  • Publication number: 20070073271
    Abstract: A catheter for use in introducing fluid into a vessel or other bodily structure. The catheter comprises a stem and a restrictor. The stem has approximate a distal end thereof a porous section that defines microholes distributed thereabout, which are inclined by a predetermined angle in the proximal direction. Affixed to the stem, the restrictor includes a conically-shaped valve with an apex thereof defining an opening and pointing in the proximal direction. The opening generally decreases in size as the conically-shaped valve flattens out distally as the pressure of the fluid within the tip increases. The forces of the fluid flowing out of the opening of the restrictor and out of the microholes of the stem substantially balance thereby substantially eliminating both recoil and whipping of the catheter, thus enabling its position to remain exceptionally stable while the fluid is finely dispersed therefrom in a cloud-like form.

  • Publication number: 20060184102
    Abstract: A system for dispensing a medium includes at least a first container to hold the medium, a pressurizing device, such as a pump, in fluid connection with the container for pressurizing the medium, and an agitation mechanism or device to maintain the components of the medium in a mixed state. The container and the pressurizing device can be separate units, as in the case of an bag or bottle in fluid connection with a peristaltic or other type of pump. The container and the pump can also be combined in a single unit, as in the case of a syringe, wherein the syringe barrel of the syringe acts to contain the medium and the syringe plunger pressurizes the medium within the syringe barrel. A method of injecting a multi-component medium includes the step of agitating the medium (for example, as described above) before or during an injection procedure to maintain the components of the medium in a mixed state.
