Hydrodynamic device for the elimination of an organic deposit obstructing a vessel of a human body

A hydrodynamic device for the elimination of an organic deposit obstructing a vessel of a human body comprising,

• a flexible hose of synthetic material insertable in said vessel,
• a bendable pressure-resistant duct extending through said hose with an annular passageway between said duct and said hose, a rear end portion of said duct extending beyond a rear end of said hose,
• handle means on rear end portions of said hose and said duct respectively for moving said duct axially and angularly with respect to said hose,
• a collar of radio opaque material on a forward end of said hose,
• a nozzle on the forward end of said duct extending beyond the forward end of said hose,
• a balloon surrounding a forward portion of said hose rearward of said collar,
• a channel leading from said balloon to a rearward portion of said hose,
• a source of high pressure liquid connected with a rear end of said duct,
• suction means connected with said passageway for withdrawing liquid from said vessel,
• a source of low pressure fluid connected with said channel for inflating said balloon,
• the bore of said nozzle having a diameter between 20 and 70 microns and said source of high pressure liquid providing a pressure sufficiently high to produce a needle-shaped jet of supersonic speed from said nozzle,
• a forward end portion of said duct being of a memory-shape type alloy and means being provided for electrically heating said forward end portion of said duct and thereby modifying the direction of the jet.
