PTFE Microintroducer Split Sheath/Dilator

PTFE Microintroducer Split Sheath/Dilator Assemblies

Our microintroducer shealth/dilator assemblies can be used 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.
Microintroducer is compatible with most 0.018” guidewires.
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.
Elimination of mechanical skiving provides a smooth and even peel.
Compatible with most therapeutic and diagnostic catheters and guidewires.
Custom lengths and sizes can be manufactured to order.
