ABSTRACT:
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).
