ABSTRACT:
Disclosed is a surgical instrument for insertion into a blood-vessel lumen and comprises a separable assembly of longitudinal sections in mating relationship having tube and hub sections. Twisting movement of lateral separator tabs integral with the proximal ends of the hub sections effects relative movement to initially unlock releasable interdigitation locking means which the tube sections incorporate distally, and which the hub sections incorporate both distally and proximally, with such continued relative movement causing biased interfaces on the hub sections to cam open and force apart the longitudinal sections.
