Publication number: 20240009372Abstract: A portable negative pressure wound therapy system includes a dressing assembly for positioning over a wound to apply a negative pressure to the wound and a canister assembly. The canister assembly includes a control unit having a vacuum source and a controller and a collection canister in communication with the dressing assembly operable to receive fluid from the wound. The collection canister has a filter assembly having a filter and a passageway between the filter and a wall of the collection canister. The collection canister also includes a canister interface having a suction port, an inlet port, and a channel. The vacuum source draws air through the suction port from the channel which draws air from the passageway connected to the channel, the air in the passageway is drawn from the collection canister through the filter, and the air in the collection canister is drawn through the inlet port.Type: ApplicationFiled: June 30, 2023Publication date: January 11, 2024Inventors: Richard M. Braga, David E. Fink, David Heagle, Arnaz S. Malhi, David R. Swisher, Scott Wudyka

Patent number: 10932810Abstract: A thrombectomy catheter system is disclosed which includes a catheter having an exhaust lumen, an infusion lumen and a high pressure tube. The high pressure tube includes a nozzle orifice for forming a high pressure jet of fluid for cutting occlusive material from within a body lumen. The nozzle orifice is positioned to direct the high pressure jet of fluid into the distal end of the exhaust lumen which creates a suctioning effect. The infusion lumen replaces fluid that is removed from the body lumen through the exhaust lumen by a suctioning effect created by the fluid jet.Type: GrantFiled: August 31, 2018Date of Patent: March 2, 2021Assignee: Covidien LPInventors: Arnaz S.

Patent number: 9421142Abstract: A compression garment apparatus includes a compression garment and a pressurizer. The pressurizer intermittently pressurizes a therapeutic bladder on the compression garment and pressurizes a support bladder on the compression garment to enhance the fit of the compression garment and maintain the therapeutic bladder in position with respect to a target compression zone on a body part on which the garment is worn. The support bladder may be selectively pressurized when needed based at least in part on sensed physical characteristics.Type: GrantFiled: May 12, 2014Date of Patent: August 23, 2016Assignee: Covidien LPInventors: Arnaz S.
