A surgical conduit leak testing system, comprising: a manifold assembly including a first manifold spaced from a second manifold, each of the first and second manifolds (46a, 46b) sealingly clampable to a respective end of a surgical conduit, the first manifold fluidly coupling a lumen of the surgical conduit to a testing gas port when the surgical conduit is sealingly clamped thereto; and a meter fluidly coupled to the testing gas port, the meter suitable for determining at least a gas flow rate; characterised in that, each of the first and second manifolds (46a, 46b) comprises a piston disposed in a chamber therein, wherein the piston is reversibly displaceable within the chamber between a first position and a second position, wherein, in the first position, the respective end of the surgical conduit is not sealingly clamped to the respective manifold (46a, 46b), and in the second position, the respective end of the surgical conduit is sealingly clamped to the respective manifold (46a, 46b); wherein at least one of the first and second manifolds (46a, 46b) includes a mandrel (60, 62), a portion of which is dimensioned to receive the respective end of the surgical conduit and an elastomeric clamping ring disposed around the portion of the mandrel (60, 62), when the piston is in the first position, the elastomeric clamping ring is radially spaced from the portion of the mandrel (60, 62) by a first distance, when the piston is in the second position, the piston compresses the elastomeric clamping ring, urging the elastomeric clamping ring radially towards the portion of the mandrel (60, 62) to a radial space of a second distance, and the first distance is greater than the second distance. a manifold assembly including a first manifold spaced from a second manifold, each of the first and second manifolds (46a, 46b) sealingly clampable to a respective end of a surgical conduit, the first manifold fluidly coupling a lumen of the surgical conduit to a testing gas port when the surgical conduit is sealingly clamped thereto; and a meter fluidly coupled to the testing gas port, the meter suitable for determining at least a gas flow rate; characterised in that, each of the first and second manifolds (46a, 46b) comprises a piston disposed in a chamber therein, wherein the piston is reversibly displaceable within the chamber between a first position and a second position, wherein, in the first position, the respective end of the surgical conduit is not sealingly clamped to the respective manifold (46a, 46b), and in the second position, the respective end of the surgical conduit is sealingly clamped to the respective manifold (46a, 46b); wherein at least one of the first and second manifolds (46a, 46b) includes a mandrel (60, 62), a portion of which is dimensioned to receive the respective end of the surgical conduit and an elastomeric clamping ring disposed around the portion of the mandrel (60, 62), when the piston is in the first position, the elastomeric clamping ring is radially spaced from the portion of the mandrel (60, 62) by a first distance, when the piston is in the second position, the piston compresses the elastomeric clamping ring, urging the elastomeric clamping ring radially towards the portion of the mandrel (60, 62) to a radial space of a second distance, and the first distance is greater than the second distance.
