Guide Extension Catheter

Guide Extension Catheter

Guide extension catheters are specialized medical devices designed to extend the length and enhance the support of a standard guide catheter. These catheters are commonly used during complex percutaneous coronary intervention (PCI) procedures, such as those involving highly tortuous blood vessels, bifurcation lesions, and chronic total occlusions (CTO). In these situations, additional backup support is necessary to navigate through challenging anatomies and to facilitate the delivery of therapeutic devices like stents or balloons to the target site within the heart or other parts of the vascular system.

Product Features

  • The only extension catheter with a liner design that can replace a small balloon for the ultimate delivery of BAT technology.


  • Extend as much as you want: 40 models to meet the needs of different lesions.


  • Two choices:


  • GEC01 series metal mesh transition segment: flexible and rigid.

  • GEC02 series half-tube transition: smooth and smooth, ultimate transportation


  • Strong support: Multi-stage gradual hardness design, strong support, fast in place.
