Device and method for external correction of insufficient valves in venous junctions

A compression device for external correction of insufficient valves and adapted for placement substantially around a junction with insufficient valves in abutting contact with a desired area of said junction, comprising:

• a plastic coated band of at least one of metal and alloy encompassing at least two veins of said junction and possessing a different rigidity and compressing force in the direction from a proximal end to a distal end thereof, said band comprising:
• at least one main compressing portion adapted to be disposed on a vein surface of said junction around the insufficient valve;
• an intermediate portion disposed adjacent said at least one main compressing portion;
• and
• a fastening portion disposed adjacent said intermediate portion.

A compression device for external correction of insufficient valves in venous junctions, adapted for placement substantially around a junction surface with insufficient valves in abutting contact with a desired area of said junction surface, comprising:

• a band of at least two layers of flexible fluid-impermeable plastic peripherally sealed together to form a band cavity having at least one hermetically isolated chamber, said band adapted to encompass at least two veins of said junction and possessing different rigidity and compressing force in the direction from a proximal end to a distal end thereof, said band including:
• at least one main compressing portion disposed on the surface of said junction around the insufficient valve, an intermediate portion disposed adjacent said main compressing portion and a fastening portion disposed adjacent said intermediate portion;
• and
• a material filling said band cavity to provide for vein compression and prevent reflux.

A method for external correction of insufficient valves in venous junctions, comprising the steps of:

• a) surgically exposing the venous junction;
• b) placing a correction device on the venous junction so that a main compressing portion of said correction device is sufficiently close to the junction to fully encompass a vein located outside around the insufficient valve, and a fastening portion of the device is disposed substantially on an adjacent vein;
• c) determining blood reflux in the vein with an insufficient valve;
• d) performing a gradual compression of the vein until the reflux disappears, by injecting a portion of at least one of a biologically inert gas and a quickly solidifying biologically inert fluid into hermetically isolated chambers of said correction device;
• e) repeating step (d) by increasing or reducing compressing in certain chambers of said band;
• f) determining a need for applying an additional compressing portion of said correction device;
• g) when application of said additional compressing portion is necessary, disposing and fastening the latter on the vein adjusting the compression rate and said portion length, cutting off a redundant piece of same, and fastening together connectors of said additional compressing portion;
• h) when application of said additional compressing portion is not necessary, cutting off the entire said additional compressing portion;
• i) checking the final correction effect, determining the blood reflux in the entire junction being corrected;
• and
• j) closing the wound by routine technique.
