It is constructed of nickel titanium alloys, stainless steel, and features a polymer coating. #### Indication for Use To provide a means to access the frontal, sphenoid and maxillary sinuses, for diagnostic and therapeutic procedures in adults aged 18 and over. ### Contraindications: None #### Technological Characteristics: The device has the same technological characteristics (i.e., design, function, materials, biocompatibility, packaging and sterilization) as the predicate device [K033321, K013024]. The device has the same technological characteristics (i.e., design, function, principle of operation, and biocompatibility) as the predicate device (Relieva Vigor Sinus Guidewire). The subject and {1}------------------------------------------------ predicate devices are all sterilized using Ethylene Oxide (EtO), validated per ISO 11135-1, and have a Sterility Assurance Level (SAL) of 10°. All devices are for single use only and are biocompatible per ISO 10993-1. #### Substantial Equivalence: The intended use and indications for use of the subject device is the same as the predicate device (Relieva Vigor Sinus Guidewire). The technological characteristics of the subject device are the same as the predicate devices, [K033321, K013024] and/or Relieva Vigor Sinus Guidewire, including: design, function, principle of operation, materials, biocompatibility, packaging and sterilization. #### Performance Data: Performance testing of the Entellus Medical Sinus Guidewire consisted of design verification testing and a cadaver study. Design verification testing included simulated use and compatibility testing. A cadaver study was conducted to support the utility of this device in the sinus spaces. Biocompatibility, sterilization, packaging, shelf life testing, animal and clinical data were not submitted. Performance testing showed that the device meets design specifications and performed as intended. #### Conclusion In conclusion, the device is substantially equivalent based on a comparison of intended use, indications for use, and technological characteristics. The device is safe and effective for its intended use. {2}------------------------------------------------ Image /page/2/Picture/1 description: The image shows the logo for the U.S. Department of Health & Human Services.
