Abstract
A vascular introducer assembly is disclosed that includes a dilator, a sheath having an axial lumen for accommodating the dilator, a locking collar for securing the dilator and the sheath to one another and an adjustable hemostatic seal for preventing fluid egress from the axial lumen and restricting insertion of instruments through the axial lumen before and after the dilator is separated from the vascular introducer.
Claims27
A vascular introducer assembly comprising:
- a) an elongated sheath having opposed proximal and distal end portions and having an axial lumen extending therethrough for accommodating a dilator;
- b) a flexible and pliable axial hub operatively associated with the proximal end portion of the sheath and having an axial bore extending therethrough in communication with the axial lumen of the sheath and further including longitudinally extending slots for dividing the hub along a longitudinal axis thereof;
- c) a cylindrical seal supported within the axial bore of the hub;
- and
- d) a rotatable actuator for moving the hub radially inward to radially compress the cylindrical seal supported therein.
