Telescope™ guide extension catheter

Telescope guide extension catheter features our TruFlex™ soft polymer tip and SmoothPass technology to help channel interventional devices.

Overview

Extended reach. Smooth delivery.

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.

Product features and design

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™ guide extension catheter (GEC) entry port

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

  1. Tapered distal pushwire section — transitions from solid, round, proximal pushwire for flexibility6
  2. Short 4 cm polymer on-ramp — maintains superior deliverability and channels interventional devices3
  3. Entry port — contributes to smooth device entry and delivery
