Abstract
A wound treating device is disclosed which is adapted to treat wounds, and particularly to enhance clotting of wounds in blood vessels. The wound treating device includes an elongated tube with proximal and distal end portions and comprising at least two lumens extending therebetween. One of the lumens is attached to receive a flow control device partially positioned within the blood vessel for providing local flow control at the wound site. Inflatable means, such as a flexible membrane, is carried generally adjacent to the distal end portion and is movable between inflated and retracted positions.

A wound treating device adapted to be positioned adjacent to an aperture in a blood vessel comprising:
- an elongated tube having proximal and distal end portions, said tube comprising at least first and second lumens extending between said proximal and distal ends;
- said first lumen adapted to receive a flow control device partially positioned within the blood vessel for providing local flow control at the aperture in the blood vessel;
- a flexible membrane carried generally adjacent said distal end portion and movable between a retracted position and an inflated position to form a balloon-like projection at said distal end;
- and
- a wound treating agent releasably pre-disposed within said elongated tube and releasable into the vicinity of the aperture in the blood vessel.
A wound treating device adapted to be positioned adjacent to an aperture in a blood vessel comprising:
- a flow control device having a tubular portion including proximal and distal ends, and a membrane attached to said distal end of said tubular portion, wherein said membrane is inflatable to define a balloon-like portion;
- a tube having proximal and distal end portions and comprising at least first and second lumens extending between said proximal and distal end portions;
- said tubular portion of said flow control device disposed within said first lumen and said membrane being positionable within the blood vessel for providing local flow control at the aperture in the blood vessel;
- a membrane carried adjacent said distal end of said tube and in fluid communication with said second lumen for inflation when pressurized fluid is introduced into said second lumen;
- and
- a wound treating agent releasably pre-disposed within said elongated tube and releasable into the vicinity of the aperture in the blood vessel.
A wound treating device adapted to be positioned adjacent to an aperture in a blood vessel comprising:
- an elongated tube having proximal and distal end portions, said tube comprising at least first, second and third lumens extending between said proximal and distal ends;
- a localized flow control device positionable through said first lumen and aperture and positionable partially within the blood vessel for providing local flow control at the location of the aperture in the blood vessel;
- an inflatable membrane carried generally adjacent said distal end of said tube and in fluid communication with said second lumen and disposed for inflation when pressurized fluid is introduced into said second lumen;
- a wound treating agent releasably pre-disposed within said elongated tube and releasable into the vicinity of the aperture in the blood vessel;
- and
- an ejector operatively coupled to said third lumen for ejecting said treating agent.
A method for treating wounds comprising the steps of:
- providing a flow control device including a tubular portion having a proximal end, a distal end and a lumen extending therebetween, and an inflatable membrane carried at said distal end of said tubular portion;
- inserting said flow control device into an aperture in a blood vessel;
- positioning the inflatable membrane of said flow control device within the blood vessel adjacent the aperture;
- introducing a wound treating device along said tubular portion of said flow control device, said wound treating device including an elongated tube having proximal and distal end portions and at least first and second lumens extending therebetween, said first lumen adapted to receive said tubular portion of said flow control device and said second lumen communicating with a membrane carried adjacent said distal end of said wound treating device;
- and
- inflating said membrane means of said wound treating device adjacent to the aperture in the blood vessel.
