Description

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.

Features

Superior deliverability3 and pushability4

Telescope™ GEC has superior deliverability3 to assist in difficult cases.

Telescope™ guide extension catheter deliverability chart shows maximum force is 182; lowest compared to other GECs.

Pushability is a critical component of deliverability.

Telescope™ guide extension catheter pushability chart shows max force is 432; highest compared to other GECs.

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

Soft polymer tip graph shows Telescope™ guide extension catheter has maximum force of 33, lowest in comparison.

Tip design

Learn about the Telescope™ guide extension catheter tip, marker band, distal segment, and main jacket.

 

  1. 2 mm TruFlex™ tip
  2. 1 mm distal marker band 
  3. 5 mm distal segment featuring soft polymer
  4. Main jacket

SmoothPass technology

Telescope™ GEC with SmoothPass technology includes three components that work together to help deliver stents, balloons, and other interventional devices.

After positioning a GEC, the ability to deliver stents, balloons, and other interventional devices through the catheter is critical. Learn how Telescope GEC can help.
Check out the Telescope™ guide extension catheter straightened out, showing entry port, polymer on-ramp, and tapered distal pushwire.
  1. Tapered distal pushwire section — transitions from solid, round, proximal pushwire for flexibility6
  2. Short 4 cm polymer on-ramp — maintains superior deliverability3 and channels interventional devices
  3. Entry port — contributes to smooth device entry and delivery
