Patent ID: 8858593

Claim:
A wound treatment device comprising: an elongated tube having an open proximal end, an open distal end, an outer surface, a luminal diameter and a luminal surface; a plunger mechanism comprising a rod element having a proximal end and a distal end and a disc element having an upper surface and a lower surface wherein the disc element has a diameter smaller that the luminal diameter of the elongated tube and is fixedly attached to and circumferentially disposed around the rod element such that the proximal end of the rod element is disposed above the upper surface of the disc element and the distal end of the rod element is disposed beneath the lower surface of the disc element and wherein the plane of the disc element is perpendicular to the longitudinal axis of the elongated tube, such the disc element of the plunger mechanism is slidably movable within the lumen of the elongated tube as the rod element is depressed into or retracted from the elongated tube; a compressible and expandable sponge-like material disposed in a compressed state within the lumen of the elongated tube between the disc element and the distal end of the elongated tube such that depression of the rod element of the plunger mechanism expels the expandable sponge-like material from the distal end of the elongated tube wherein the sponge-like material freely expands; and a break-seal vessel, containing a liquid composition that polymerizes upon contact with body fluids, disposed within the expandable sponge-like material, wherein the break-seal vessel is configured and positioned to maintain contact with the distal end of the rod element of the plunger mechanism such that certain controlled movements of the rod element effects breakage of the break-seal vessel and concomitant release of the polymerizable liquid composition.
