Abstract (en)
[origin: EP0000831A1] A cannula assembly for bidirectional blood flow using co-extensive telescopic cannulae, and including a venipuncture needle (40) which during puncturing projects forwardly of the cannulae to facilitate venipuncture and is then displaceable away from the venipuncture site to permit unobstructed simultaneous fluid flow in opposite directions through the cannulae. The inner cannula (38) may be fixed or longitudinally displaceable.
