The seeker-based design of the XprESS device delivers the familiar control and tactile feel physicians rely on to access even the most tortuous nasal anatomy.


Precision brings success. Studies show physicians achieve a consistent, high technical success rate reaching and dilating targeted sinus ostia when using the XprESS device.1


Reshapeable tip can be adjusted to an infinite number of angles to meet the unique anatomical challenges of each patient.

Supplied bending tool delivers optimal angle ranges to access natural sinus ostia and avoid sensitive anatomy.


The slim profile and small ball tip of each XprESS device allows for smooth movement through tight nasal passages and easy endoscopic viewing of treatment.

Single Device

The unique malleable tip of the XprESS device can be reshaped to treat the frontal, maxillary and sphenoid sinuses, as well as Eustachian tubes as appropriate.

Broadest Indication

XprESS is approved for balloon dilation to treat maxillary sinuses in patients (2+) as well as the frontal and sphenoid sinuses in patients (12+). In addition, ETD patients (18+) can also be treated.

Easy Integration

With our easy-to-use devices, staff training takes minutes, not hours –in any preferred setting.

Accredited Technology

Not only is XprESS device clinically proven to provide safe, effective and durable outcomes, it is the ONLY balloon dilation technology to receive positive guidance from the National Institute for Health and Care Excellence (NICE) Medical Technologies Advisory Committee for the treatment of chronic sinusitis after medical treatment has failed.
