Sealing blood vessel fistula - involves inserted sleeve with spiral support with turns bridged by impervious elastic material

摘要

The inserted sleeve seals a vein or artery containing fistulae, aneurysmata etc. It comprises a strong ductile spiral support (3), adjacent turns of which are bridged by elastic material impervious to liquid. Typically this can consist of a hose fitting closely round the support. Alternatively, separate spiral supports can be contained in the hose only at the ends. USE/ADVANTAGE - Keeps the passage in the blood vessel free while sealing off fistulae etc.
