INSTRUMENT FOR PREVENTION OF CONSTRICTIONS IN THE JOINT AREA AT THE APPLIANCE OF BRANCHING ON VESSEL

摘要

Instrument for use at the applying of branching on vessel by means of anastomosis rings in order to prevent constrictions in the joint area, which is T-shaped, the vertical part of the T being constituted by an unyielding pipe (1) or hose whereas the upper part (3) of the T is elastic. The upper part of the T constitutes a closed space but for a connection with the vertical hose or pipe. The upper part of the instrument can in evacuated state be inserted through a cut in a vessel wall, then to be blown up to expand the vessel, before an anastomosis end to side is conducted by means of an anastomosis ring.
