The invention also provides an assembly for extracorporeal circulation comprising an introducing instrument and a connecting instrument. The introducing instrument includes a sheath introducible into a blood vessel, and a proximal part communicating with the sheath and having a plurality of introduction passages provided with haemostatic valves. The connecting instrument includes a tubular portion capable of being connected with at least one of the introduction passages of the proximal part of the introducing instrument and capable of being inserted in a liquid-tight manner through the haemostatic valve disposed in the connected introduction passage. in:
