Peterson Vice President Clinical, Regulatory and Quality (763) 463-7066 kpeterson@entellusmedical.com Device Information: Trade Name: Common Name: Classification Name: Product Code: Regulation Number: Predicate Device: XprESS Multi-Sinus Dilation Tool [K102003] #### Device Description: The XprESS Multi-Sinus Dilation Tool is intended to remodel or recreate the sinus outflow tract via trans-nasal balloon dilation. The XprESS device combines features of a curved suction tip and a frontal ostium seeker with the tissue expansion effect of balloon dilation. The familiar features of this device enable a physician to track the device to the sinus ostium using endoscopic visualization. Since the distal end of the device is re-shapeable, one balloon can be modified to work on multiple sinuses within the same patient. XprESS is offered in three balloon sizes: 5mm, 6mm and 7mm diameter balloons. LRC The XprESS Multi-Sinus Dilation Tool has been tested to withstand multiple inflations and device tip manipulations (up to 25) in a surgical case wherein all 6 sinus ostia are being dilated. The XprESS device curved suction tip has a 2 mm atraumatic ball tip with a 1 mm inside diameter. A suction tube may be connected to the proximal barbed fitting to provide active suction by covering the suction vent. An Infusion Line connected to a syringe may be connected to the proximal barbed fitting to provide irrigation. The device was designed to prevent fluid from exiting the suction vent during irrigation. {1}------------------------------------------------ Image /page/1/Figure/0 description: The image shows a diagram of a medical device with several labeled parts. The device has a long, thin body with a curved suction tip at one end. The other end has a proximal barbed facing and a balloon inflation luer. The diagram also labels the balloon slide mechanism and the suction vent. XprESS Multi-Sinus Dilation Tool The XprESS Multi-Sinus Dilation Tool is provided sterile and for single use only. The items packaged with the Xpress Multi-Sinus Dilation Tool include the Inflation Device and Infusion Line. ### Indication for Use: To access and treat the frontal recesses, sphenoid sinus ostia and maxillary ostia/ethmoid infundibula in adults using a trans-nasal approach. The bony sinus outflow tracts are remodeled by balloon displacement of adjacent bone and paranasal sinus structures. ### Contraindications: - Do not use this XprESS device in patients who are allergic to nickel or barium sulfate. . - Do not attach the XprESS device directly to the CT Image Guidance systems. This may . result in inaccurate device positioning. ### Technological Characteristics: The XprESS device has the same indications for use and fundamental scientific technology as the predicate device [K102003]. The device has the same technological characteristics (i.e., basic design, function, mode of operation, packaging, shelf life and sterilization) as the predicate device. Both devices are sterilized using Ethylene Oxide (EtO) and are not labeled as nonpyrogenic. Both devices are for single use only. Both devices are biocompatible per ISO 10993l . ### Substantial Equivalence: The XprESS device was modified to provide additional balloon sizes, a suction vent, and the device handle was modified to improve ergonomics. The XprESS device has the same indications for use and fundamental scientific technology as the predicate device [K 102003]. The XprESS device is substantially equivalent to the predicate device. ## Performance Data: Performance testing of the XprESS device consisted of biocompatibility, design verification and simulated use in a cadaver model. Design verification included dimensional, functional and simulated use testing. Animal and clinical data was not submitted. Performance testing showed that the device meets design specifications and performed as intended. ### Conclusion: In conclusion, the indications for use and technological characteristics are the same as or equivalent to the predicate device. Performance testing has demonstrated that the device is safe and effective and that its performance is substantially equivalent to the predicate device. {2}------------------------------------------------ Image /page/2/Picture/1 description: The image shows the logo for the U.S. Department of Health & Human Services.
