The XprESS Multi-Sinus Dilation System has been proven to enable comfortable treatment of patients in the office or the OR. XprESS delivers:1


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


Precision brings success. Studies show physicians achieve a consistent, high technical success rate reaching and dilating targeted sinus ostia when using XprESS.2

Direct Control and Feedback

Semi-rigid tip delivers tactile feel to aid in navigation and allows for gentle palpation and manipulation of anatomy.


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

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.


Back port provides the flexibility to attach suction and irrigation, as needed.


XprESS was designed with the office in mind, each design choice aimed at simplifying both the procedure and the process of practice integration.

Hassle Free

Battery-powered, integrated LED Light Fiber eliminates need for extra light sources and cables.


One finger advancer gently slides the balloon to device tip for treatment.


Inflation syringe requires only single depression to reliably achieve 12 atm of pressure and connects simply to inflation port on XprESS.


Supplied bending tool allows quick shaping into optimal angle ranges to access natural sinus ostia and avoid sensitive anatomy.


With easy-to-use devices, staff training takes minutes, not hours — in the OR and the office.


With the XprESS family of devices, physicians can apply a combination of five methods to confidently confirm device placement.

  • Direct visualization
  • Tactile feel
  • 1cm and 2cm depth markings
  • Transillumination
  • Tip excursion
