INTERLOCKING SHEATH/DILATOR ASSEMBLIES

AT A GLANCE

  • Patented, interlocking hub design prevents dilator “push back”
  • T-hub provides a secure grip during peeling
  • Custom lengths and half-French sizes available

Designed for Outstanding Performance

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