Cooley Vascular Dilator 4.0mm, 13cm

Clinical Application

Designed for controlled dilation of small- to medium-caliber vessels, this dilator facilitates atraumatic expansion of vessel lumens during vascular procedures. Common uses include sizing and dilating arteriotomies, preparing vessels for graft or conduit anastomosis, facilitating passage of cannulae or sutures, and gentle lumen preparation in peripheral and bypass procedures where a 4.0 mm profile is required.

Design & Configuration

The straight, progressively tapered profile provides predictable, stepwise dilation to the target diameter while the rounded atraumatic tip minimizes endothelial trauma during advancement. The 13 cm length offers sufficient reach for peripheral and proximal exposures without added bulk. Smooth surface finish reduces friction against vessel walls and graft material, improving control during delicate maneuvers.
