[Complete Guide] Guiding Sheaths and Guiding Catheters for EVT

What is a Guiding Sheath?

A guiding sheath is a dedicated vascular access device employed in Endovascular Therapy (EVT) for peripheral arterial interventions. In contrast to conventional introducer sheaths, guiding sheaths are constructed with an embedded metallic braid within the shaft, significantly enhancing kink resistance and torque control. They are manufactured in a variety of tip configurations, lengths, and inner diameters, enabling tailored selection based on anatomical considerations and procedural demands.

The guiding sheath is typically advanced to a position as close as safely possible to the target lesion, serving as a stable conduit that facilitates the delivery and exchange of endovascular devices. By reducing the distance from the vascular access point to the treatment site, the sheath improves device trackability, procedural efficiency, and overall operator control.
