Catheter introducers, Mullins Design are used to introduce balloon, electrode, closed or non-tapered end catheters, and other devices. Its uniquely fabricated sheath design provides maximum flexibility without kinking or compression. Its preformed curves combined with soft, distal tip allow a traumatic engagement of target vessels.

Catheter is a thin and flexible tube that can be inserted into a body cavity, duct or vessel in order to allow fluids to pass into or out of it, to distend (expand) it, or to convey diagnostic or other instruments through it. The process of inserting a catheter is catheterisation.
