Abstract

Abstract A wound clotting device includes a tubular portion having a proximal end, a distal end and a lumen extending therebetween, an inflatable membrane associated with the distal end of the tubular portion and being moveable between a retracted position and an inflated position to form a balloon-like projection at the distal end when moved to the inflated position for treating a wound. A method for treating a wound by providing a wound-treating device, positioning the device in a location near the wound, moving an inflation membrane of the wound treating device to an inflated position near the wound, and removing the treating device is described. Finally, an alternate wound treating device having an inflatable membrane which is releasably carried at the distal end of the tubular portion and which is expelled to treat the wound is also described.
