Patent ID: 7141060

Claim:
An instrument for inserting a prosthesis hose connection between two blood vessels, in particular arteries ( 12 ), or arterial regions, comprising a flexible connecting hose ( 11 ) which is impermeable to blood and which carries an expandable tubular metal grid ( 13 ) arranged at an angle to its longitudinal axis at at least one end, and preferably only at one end, said metal grid ( 13 ) having a blood impermeable inner liner and/or covering ( 15 ) and extending from the relevant end of the hose ( 11 ) like a cross bar of a T in two opposite directions, with an expansion balloon ( 24 ) expandable by a pressurized fluid being disposed within the metal grid ( 13 ) and being preferably charged with pressurized fluid via a pressurized fluid delivery hose ( 25 ) guided through the connecting hose ( 11 ) for the expansion of the metal grid ( 13 ), characterized in that the metal grid ( 13 ) with the inner liner and/or covering ( 15 ) and the expansion balloon ( 24 ), is held at the proximal end of a catheter ( 28 ) in a state pivoted relative to the connecting hose ( 11 ) such that the cross bar of a T formed by the metal grid ( 13 ), with the inner liner and/or covering ( 15 ) and the expansion balloon ( 24 ), thereby extends at least approximately in the longitudinal direction of the catheter ( 28 ); and the connecting tube ( 11 ), with the delivery tube ( 25 ) arranged therein, is arranged at the outer side of the catheter ( 28 ) in the longitudinal direction of the same.
