The device includes an inflatable sleeve adapted to surround the limb; a conduit attached to the sleeve for delivering fluid to the sleeve; and a portable, wearable controller attached to the conduit that generates and controls the flow of fluid in the device. ## Claims ### Claim 1 A compression device for the limb of a mobile patient comprising: an inflatable sleeve adapted to surround the limb; a conduit attached to said sleeve for delivering fluid to said sleeve; and a portable, wearable controller attached to said conduit that generates and controls the flow of fluid in the device, the controller comprising a microprocessor control system and a pump, wherein the device is configured to provide compression to the limb using the inflatable sleeve and provide a silent mode in which the device applies compression but if the pressure falls after a period of time the device does not operate the pump to compensate and the patient can switch the device out of silent mode and reactivate the pump. ### Claim at position 2 2-3. (canceled) ### Claim 4 (depends on 1) The compression device as claimed in claim 1, wherein said sleeve includes one or more individually inflatable cells. ### Claim 5 (canceled) ### Claim 6 (depends on 1) The compression device as claimed in claim 1, wherein said sleeve includes a leg cuff and a foot cuff. ### Claim at position 6 7-8. (canceled) ### Claim 9 (depends on 6) The compression device as claimed in claim 6, wherein said leg cuff includes at least three cells. ### Claim 10 (depends on 1) The compression device as claimed in claim 1, wherein said controller is battery operated. ### Claim 11 (depends on 4) The compression device as claimed in claim 4, wherein each cell is monitored by a sensor. ### Claim 12 (canceled) ### Claim 13 (depends on 9) The compression device as claimed in claim 9, wherein said cells include a gaiter cell, adapted to wrap around the lower limb in the region closest to the ankle, a mid-calf cell, adapted to wrap around the lower limb above the region occupied by the gaiter cell and an upper cell adapted to wrap around the lower limb in the region between the mid-calf cell and the knee. ### Claim 14 (depends on 9) The compression device as claimed in claim 9, wherein said cells may be pressurized to the same or different predetermined pressures. ### Claim at position 13 15-18. (canceled) ### Claim 19 A compression device for the limb of a mobile patient comprising: an inflatable sleeve adapted to surround the limb; a conduit coupled to said sleeve for delivering fluid to said sleeve; and a portable, wearable controller coupled to said conduit that generates and controls the flow of fluid, the controller comprising a microprocessor control system and a pump, wherein the controller is configured to allow a patient to selectively operate the device in dynamic compression in which the pressure is monitored during use to provide the dynamic compression and maintain a preset compression profile on the limb or operate the device in a silent mode in which the device applies compression but if the pressure falls after a period of time the device does not operate the pump to compensate. ### Claim 20 (depends on 19) The compression device as claimed in claim 19, wherein the controller is configured to allow the patient to switch the device out of silent mode and reactivate the pump. ### Claim 21 (depends on 19) The compression device as claimed in claim 19, wherein said sleeve includes one or more individually inflatable cells. ### Claim 22 (depends on 19) The compression device as claimed in claim 19, wherein said sleeve includes a leg cuff and a foot cuff. ### Claim 23 (depends on 19) The compression device as claimed in claim 19, wherein said controller is battery operated. ### Claim 24 (depends on 21) The compression device as claimed in claim 21, wherein each cell is monitored by a sensor. ### Claim 25 A compression device for the limb of a mobile patient comprising: an inflatable sleeve adapted to surround the limb; a conduit coupled to said sleeve for delivering fluid to said sleeve; and a portable, wearable controller coupled to said conduit that generates and controls the flow of fluid, the controller comprising a microprocessor control system and a pump, wherein the device is configured to provide compression to the limb using the inflatable sleeve and the device is configured to provide a silent mode in which the pump is disabled and all valves are kept closed. ### Claim 26 (depends on 25) The compression device as claimed in claim 25, wherein the controller is configured to allow a patient to selectively operate the device in dynamic compression in which the pressure is monitored during use to provide the dynamic compression and maintain a preset compression profile on the limb or operate the device in the silent mode in which the device applies compression but if the pressure falls after a period of time the device does not operate the pump to compensate. ### Claim 27 (depends on 25) The compression device as claimed in claim 25, wherein said sleeve includes one or more individually inflatable cells. ### Claim 28 (depends on 25) The compression device as claimed in claim 25, wherein said sleeve includes a leg cuff and a foot cuff. ### Claim 29 (depends on 25) The compression device as claimed in claim 25, wherein said controller is battery operated. ### Claim 30 (depends on 25) The compression device as claimed in claim 25, wherein each cell is monitored by a sensor.
