  • Patent number: 8192397
    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.

  • Patent number: 8182444
    Abstract: A system for delivering a fluid comprising cells to tissue of a patient includes a container holding an injection fluid and a powered drive. A sensor system provides a measurement indicative of at least shear forces on the cells to a control system. Based at least in part on this measurement, the control system is adapted to transmit a control signal to the powered drive for pressurizing the contents of the container to deposit cells within the tissue of a patient via a fluid path and a patient interface.

  • Publication number: 20080086050
    Abstract: Hyperthermia has been applied by, for example, separate ultrasound transducers, RF or microwave transmitters and heated fluids. Imaging by separate MRI imaging coils is usually used to view the anatomical region under treatment. Separate temperature probes (needles, catheters) are often used to monitor tissue temperature. Control of the temperature profile required for effective hyperthermia treatment is usually done by trial and error, involving a human operator. The present invention combines all of these capabilities into a single device, which is MRI compatible and safe. It also allows for automatic control of the RF energy to achieve a prescribed tissue hyperthermia.

  • Patent number: 7351221
    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.
