Why is a thin-wall guiding sheath important for R2P cases?

A thin-wall guiding sheath is crucial for R2P (radial to peripheral) cases because it enables the delivery of devices through smaller access points while maintaining a large inner lumen. This design allows physicians to use a destination sheath or guiding sheath that supports complex interventions without needing larger arterial access, which reduces the risk of complications. In radial access procedures extending to peripheral targets, a thin-wall guiding sheath optimizes patient comfort and reduces the potential for spasm. It also permits the passage of a guiding catheter with sufficient support and torque response, enhancing precision during challenging radial to peripheral interventions.
