The invention relates to a device for treating blood flow in an internal wound, including a handling member connected to a series of successively narrower tubes, each tube including a liquid-expandable article. The tubes can be pivotably connected to each other, allowing the tubes to conform to the contours of the wound, or fixed together. The tubes can be encased in a liquid-soluble layer that keeps the liquid-expandable article sequestered from liquids.
The stepwise-tapering profile of the device allows for its insertion into the internal wound with little or no resistance until fully seated. Upon encountering liquids within the wound, the liquid-soluble layer can dissolve to expose the liquid-expandable article. When exposed to the wound liquids, the liquid-expandable element can expand in volume, providing compressive pressure against internal wound surfaces and minimizing blood loss.
The tubes and the liquid-expandable element can include therapeutic agents for treating the wound.
