Cooley Vascular Dilator 5.0mm, 13cm

Clinical Application

This dilator is designed to atraumatically dilate vascular lumens and arteriotomy sites to facilitate passage of cannulas, sheaths, and catheters during open vascular and cardiovascular procedures. Common applications include peripheral and central vessel dilation during bypass grafting, cannulation for cardiopulmonary bypass, access creation for dialysis procedures, and controlled dilation during device exchanges. The 5.0 mm diameter provides a defined lumen size for matching with correspondingly sized cannulae or introducer sets, while the 13 cm shaft length offers reach for most peripheral and central access scenarios.

Design & Configuration

The instrument features a gradual, smooth taper terminating in an atraumatic tip to minimize intimal injury and reduce the risk of vessel tearing during dilation. The straight, single-ended geometry and moderate 13 cm shaft length give the operator tactile feedback and control while negotiating vessel courses and arteriotomy sites. The defined 5.0 mm diameter helps clinicians select appropriate dilator size relative to intended cannula or sheath outer diameter, enabling predictable dilation without excessive oversizing.
