INTRODUCTION RULES FOR A PROCESS CONCLUSION

摘要

The invention relates to an instrument for inserting a prosthesis tube connection between two blood vessels, especially arteries ( 12 ) or arterial areas, comprising a flexible, blood-impermeable connecting tube ( 11 ) which supports an expandable tubular metal screen ( 13 ) at at least one end, preferably only at one end, said screen being positioned at an angle to the longitudinal axis of the connecting tube and having a blood-tight inner lining and/or outer covering ( 15 ). Said screen extends in two opposite directions ( 11 ) from the end of the tube concerned, in a transversal T-bar. An expansion balloon ( 24 ) which can be expanded with a pressurised fluid is located inside the metal grid ( 13 ) and can be subjected to the action of the pressurised fluid through a pressurised fluid delivery tube ( 35 ) that is preferably guided through the connecting tube ( 11 ), for the purpose of expanding the metal screen ( 13 ). The invention is characterised in that the metal screen ( 13 ), together with the inner lining and/or the covering ( 15 ) and the expansion balloon ( 24 ) are held in a pivoted position in relation to the connection tube ( 11 ) at the proximal end of a catheter ( 28 ), in such a way that the transversal T-bar formed by the metal screen ( 13 ), the inner lining and/or the covering ( 15 ) and the expansion balloon ( 24 ) extends at least approximately in the longitudinal direction of the catheter ( 28 ).
