Abstract
Systems, devices, and methods of the present application can accelerate and reduce medical complications associated with healing of non-planar wounds such as amputation wounds. The devices and methods utilize a collapsing structure and negative pressure to cause the shaped wound to preferentially close. The structure can accommodate movement over curved tissue surfaces, which can utilize scales or interleaved elements to provide efficient wound closure along arcuate paths. This structure can enable gradual closure from the deepest portion of the wound to the shallowest portion.
Claims26
A method for treating an open wound comprising:
- surgically preparing a wound opening for negative pressure therapy;
- positioning a compression wound closure device external to the wound;
- and
- applying pressure to the wound using the compression wound closure device to exert a force on tissue within the wound opening wherein the wound is treated with negative pressure.
A negative pressure wound closure device to treat a wound comprising;
- a collapsible structure positionable external to a wound opening, the collapsible structure that extends over at least a portion of tissue of the wound opening, the collapsible structure having articulating elements that are displaced during movement of spaced apart wound margins of the wound opening;
- and
- a plurality of scale elements positioned between the structure and a tissue surface.
