Paranasal sinus guide-catheter

Paranasal sinus guide-catheters are flexible, sterile tubes designed to assist in accessing sinus cavities during medical procedures. Clinically, they serve as a guide for inserting other instruments, enabling safer and more precise interventions like drainage, biopsy, or balloon dilation of blocked sinus passages.

These devices are typically single-use and regulated as medical instruments, with classification and supply rules varying by jurisdiction. They are often supplied sterile and intended for professional use in outpatient or hospital settings, where sinus-related procedures are performed.
