Overview

An extension of you

The Performance You Want For Your Complex Clinical Practice.

In difficult cases, guide extension catheters (GEC) provide extra backup support and improve access to distal lesions.1

Telescope™ GEC features bold technology — and our market-leading2 catheter expertise.

Superior deliverability3 and pushability4

Telescope GEC has superior deliverability3 to assist in difficult cases.

Pushability is a critical component of deliverability.

TruFlex™ soft polymer tip

You want a soft, flexible tip with responsiveness when you need it.

Our extruded TruFlex tip required at least 39% less force to deflect.5

Smoothpass technology

After positioning a GEC, the ability to deliver stents, balloons, and other interventional devices through the catheter is critical.

Telescope GEC with SmoothPass technology includes three components that work together to help channel interventional devices:

Close up image of straightened catheter
  1. Tapered distal pushwire section — transitions from solid, round, proximal pushwire for flexibility
  2. Short 4 cm polymer on-ramp — maintains superior deliverability3 and channels interventional devices
  3. Entry port — contributes to smooth device entry and delivery

  • Coil-reinforced design and hydrophilic coating help improve flexibility and deliverability
  • PTFE liner provides a low-friction inner lumen
