Telescope™ guide extension catheter
For coronary artery disease
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
Tip design
- 2 mm TruFlex tip
- 1 mm distal marker band
- 5 mm distal segment featuring soft polymer
- Main jacket
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:
- Tapered distal pushwire section transitions from solid, round, proximal pushwire for flexibility6
- Short 4 cm polymer on-ramp maintains superior deliverability and channels interventional devices3
- Entry port contributes to smooth device entry and delivery

- Spade-shaped marker band confirms orientation of catheter on fluoroscopy
- Entry port
- Resolute Onyx™ DES traveling along the on-ramp toward the entry port

Distal 25 cm of catheter
- Coil-reinforced design and hydrophilic coating help improve flexibility and deliverability
- PTFE liner provides a low-friction inner lumen
- Flexible TruFlex soft polymer tip5
- Rigid polymer in proximal jacket for luminal integrity6
- Flexible polymer in main jacket for deliverability
- Solid, round pushwire featuring superior pushability4
