21 Gauge Epidural Catheters: Supporting Your Procedural Approach
Supporting Procedural Confidence
In epidural procedures, catheter behavior plays a key role in:
- Navigation within the epidural space
- Visualization under fluoroscopy
- Delivery of therapeutic agents
Epimed’s 21 Gauge catheter designs are developed to support these core procedural elements, providing consistent and predictable performance.

Frequently Asked Questions
A 21G epidural catheter is used for targeted medication delivery in procedures such as epidural steroid injections and transforaminal approaches. It allows controlled navigation within the epidural space.
They differ in flexibility, control, tip design, and fluoroscopic visibility, which influence catheter behavior during navigation and delivery.
Steerable catheters are typically used for site-specific procedures where greater directability is needed.
Greater control is important when navigating complex anatomy or hardware is critical.
Open tips support forward delivery, while closed tips with side ports support lateral distribution within the epidural space.
Visibility under fluoroscopy supports accurate positioning and real-time adjustment during catheter navigation.
Catheter length determines reach and access, depending on the procedural approach and anatomical target.
