Interlocking Sheath/Dilator Assemblies

Interlocking Sheath/Dilator Assemblies

Our shealth/dilator assemblies are specifically designed for the percutaneous placement of short and long-term therapeutic and diagnostic catheters.

Product Highlights

Patented interlocking hub design that prevents dilator "push back" during insertion.
Sheath tips have zero clearance between dilator shaft and sheath tip, which reduces the risk of "roll back" during placement.
Easy grip T-hub provides a secure grip during peeling and removal.
The dilator tip radius provides a smooth transition from the guidewire.
French sizes are permanently molded on the dilator hub for easy identification.
The PTFE peelable design permits elimination of mechanical skiving, providing a smooth and even peel.
Compatible with most therapeutic and diagnostic catheters and guidewires.
Standard introducers are compatible with 0.035" and 0.038" diameter guidewires.
