Abstract

The disclosure describes a system that may be used to deliver a plurality of therapies using one portable device. The system includes a fluid pump that pumps fluid from a container to a therapy device to treat a patient. The fluid pump resides within a pump bay of the therapy delivery device. The fluid may be used to increase cool a tissue of the patient or clear debris. In one embodiment, generated signals may be delivered by a peripheral accessory connected to the generator through the connector board, and the generator may generate radio frequency (RF) energy for the purpose of prostate tissue ablation, where the effective ablation area of an electrode is increased by the fluid. In addition, the therapy delivery device may include a touch screen user interface, a visual operation indicator, a signal generator, and a removable connector board.

Claims

1. A portable therapy delivery system, comprising:

a generator system, comprising;

a device housing comprising a carrying handle,

a RF generator in the device housing,

a pump bay recessed in the device housing, and a replaceable fluid pump in the pump bay,

a hinged pump bay door mounted on the device housing and overlying the pump bay and the pump, wherein the pump bay door, when in an open position, provides access to the fluid pump from outside the device housing, and when closed, lies flush against the device housing;

a screen housing, separate from the hinged pump bay door, rotatably mounted on the device housing;

a hand-held tissue ablation device, separate from the generator system, wherein the ablation device comprises a probe with a probe fluid conduit and an electrode in the probe;

an electric cable to provide an electrical connection between the RF generator in the generator system and the electrode in the hand-held ablation device; and

a generator system fluid conduit to deliver fluid from the pump in the generator system to the probe fluid conduit in the hand-held ablation device.

2. The portable therapy delivery system of claim 29, wherein an external surface of the screen housing comprises a visual operation indicator.

3. The portable therapy delivery system of claim 29, wherein the fluid pump is a positive displacement pump selected from one of a peristaltic pump, an external gear pump, and internal gear pump, a vane pump, a flexible member pump, a lobe pump, a circumferential piston pump, and a screw pump.

4. The portable therapy delivery system of claim 31, wherein the fluid pump is a peristaltic pump.

5. The portable therapy delivery system of claim 29, wherein the pump bay further comprises a channel disposed inside a perimeter of the pump bay.

6. The portable therapy delivery system of claim 29, wherein the screen housing comprises a touch screen user interface.

7. The portable therapy delivery device of claim 30, wherein the visual operation indicator comprises a plurality of lights.

8. The portable therapy delivery device of claim 29, wherein the generator system further comprises within the housing a processor that controls a rate that the fluid is moved from a reservoir to the hand-held ablation device.

9. The portable therapy delivery device of claim 29, wherein the hand-held ablation device further comprises a trigger mechanism, wherein the trigger mechanism is pressure sensitive to allow an operator to control at least one of an amount of RF energy from the RF generator and a rate of fluid flow from the fluid pump.

10. The portable therapy delivery device of claim 36, wherein the hand-held ablation device further comprises a memory chip in communication with the processor to prevent re-use of the hand-held ablation device.

11. The portable therapy delivery device of claim 38, wherein the memory chip creates a log to identify the therapy delivered and record that the hand-held ablation device has been used.

12. A portable therapy device, comprising:

a device housing comprising a carrying handle,

a RF generator in the device housing,

a pump bay recessed in the device housing, and a replaceable fluid pump in the pump bay,

a processor in the device housing, wherein the processor controls at least one of the RF generator and the fluid pump,

a hinged pump bay door mounted on the device housing and overlying the pump bay and the pump, wherein the pump bay door, when in an open position, provides access to the fluid pump from outside the device housing, and when closed, lies flush against the device housing, and

a screen housing, separate from the hinged pump bay door, rotatably mounted on the device housing, wherein the screen housing comprises a touch screen graphic user interface.

13. The portable therapy device of claim 40, wherein the fluid pump is a peristaltic pump.

14. The portable therapy device of claim 40, wherein the pump bay further comprises a channel disposed inside a perimeter of the pump bay.

15. The portable therapy device of claim 40, wherein the screen housing further comprises a visual operation indicator, and wherein the visual operation indicator comprises a plurality of lights.

16. A portable therapy delivery system, comprising:

a generator system, comprising;

a device housing comprising a carrying handle,

a RF generator in the device housing,

a pump bay recessed in the device housing, and a fluid pump in the pump bay, wherein the fluid pump is removable and replaceable;

a hinged pump bay door mounted on the device housing and overlying the pump bay and the pump, wherein the pump bay door, when in an open position, provides access to the fluid pump from outside the device housing, and when closed, lies flush against the device housing;

a screen housing, separate from the hinged pump bay door, rotatably mounted on the device housing;

a hand-held tissue ablation device, separate from the generator system, comprising a trigger mechanism, wherein the trigger mechanism is pressure sensitive to allow an operator to control at least one of an amount of RF energy from the RF generator and a rate of fluid flow from the fluid pump, and wherein the ablation device further comprises a probe with a probe fluid conduit and an electrode in the probe;

an electric cable to provide an electrical connection between the RF generator in the generator system and the electrode in the hand-held ablation device; and

a generator system fluid conduit to deliver fluid from the pump in the generator system to the probe fluid conduit in the hand-held ablation device.
