  • Publication number: 20240009372
    Abstract: 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.

  • Patent number: 10932810
    Abstract: 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.

  • Patent number: 9421142
    Abstract: 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.

  • Patent number: 9205021
    Abstract: A compression device for providing compression treatment to a limb of a wearer includes a compression garment positionable on the limb of the wearer. The garment includes an inflatable bladder for providing compression treatment to the limb. A controller is adapted for fluidly connecting to the inflatable bladder and configured for inflating and deflating the bladder during a compression cycle. The controller has an exhaust port positioned to direct exhaust fluid through the bladder so exhaust fluid flows over the limb of the wearer to cool the limb.

  • Patent number: 9125787
    Abstract: A compression garment for applying compression therapy to a body part of a person. The compression garment includes a bladder including an inflatable chamber having a perimeter and an opening through which the inflatable chamber is inflated. A foam layer is positioned at least partially in the inflatable chamber for reducing a volume of gas required to inflate the inflatable chamber and extends at least partially outside the inflatable chamber for providing structural support to the compression garment.

  • Patent number: 9072867
    Abstract: A catheter is provided which includes a body having a proximal end, a distal end and a sidewall defining at least one lumen. The catheter body has at least one side opening formed through the sidewall at a location spaced proximally from the distal end. The at least one side opening communicates with the at least one lumen. A recess extends along the sidewall and communicates with the at least one side opening such that the recess defines a fluid pathway into the side opening.

  • Publication number: 20130085431
    Abstract: A compression apparatus for providing a therapeutic compression pressure to a wearer's body. The apparatus includes an inflatable bladder formed from bladder material, a controller, and a pump operatively connectable to the bladder for pressurizing the bladder. The controller has a pre-therapeutic compression function for instructing the pump to pressurize the bladder to an elevated pressure above the therapeutic compression pressure and to maintain the elevated pressure for a period of time before depressurizing the bladder.

  • Publication number: 20130085427
    Abstract: A compression garment having a sealable bladder pocket adapted for applying compression therapy to a selected body part of a patient. The compression garment includes a selectively inflatable bladder and a wrap having a selectively sealable pocket. The pocket has a sealable main opening sized for passing the bladder therethrough for inserting the bladder in the pocket and removing the bladder from the pocket. A connector on the bladder may be connected to a fluid supply line via the main opening. In other embodiments, the connector may be connected in fluid communication with the fluid supply line via a secondary opening separated from the main opening. Fluid is delivered from the fluid source to an inflatable interior of the bladder to impart compression therapy to the body part.
