Problem
Chronic sinusitis treatment often requires multiple surgical instruments to access and dilate various sinus cavities, leading to increased procedural complexity and costs. Current balloon sinus dilation (BSD) devices may lack versatility and compatibility with existing ENT surgical tools.

This universal design allows surgeons to use a single device for the frontal, maxillary, and sphenoid sinuses, reducing the need for multiple specialized instruments. The Sinusleeve® Balloon accommodates a range of rigid, flexible, and reusable positioning and suction devices, providing versatility and compatibility. By integrating with familiar surgical workflows, the Sinusleeve® Balloon aims to improve procedural efficiency and lower costs associated with chronic sinusitis treatment.
