It is labeled non-sterile and must be cleaned and sterilized or cleaned and high level disinfected prior to each use. The Light Seeker comes with two standard light post adapters, which allow the device to be compatible with commonly used 2.5mm light guides (cables). Image /page/0/Figure/16 description: The image shows a diagram of a medical instrument. The instrument has a curved, tapered probe with a 1.5 mm lighted ball tip. The instrument also has a handle and a light post. PathAssist™ Light Seeker™ {1}------------------------------------------------ Entellus Medical #### Indications for Use: The PathAssist Light Seeker is intended to locate, illuminate within, and transilluminate across nasal and sinus structures, including the frontal, ethmoid and maxillary sinuses, in patients aged 18 and over. #### Contraindications: None #### Technological Characteristics: The Light Seeker has the same indications for use and fundamental scientific technology as the predicate device [K110158]. The subject device has the same technological characteristics (i.e., principle of operation, design, function, materials, and biocompatibility per ISO 10993-1) as the predicate device. The reprocessing methods for the subject device have been modified to include the option of high level disinfection, in addition to the previously cleared validated methods for cleaning and sterilization. #### Substantial Equivalence: The Light Seeker has the same indications for use and fundamental scientific technology as the predicate device. The Light Seeker is substantially equivalent to the predicate device. #### Performance Data: Performance testing of the Light Seeker consisted of design verification testing after repetitive reprocessing cycling consisting of manual cleaning and manual high level disinfection. Design verification testing included functional testing to support the useful life of the device. High level disinfection validation results obtained from device [K102366] were submitted. Cleaning validation results obtained from device [K102366] and sterilization validation data were submitted and cleared for the subject device in [K110158]. Biocompatibility, packaging testing, animal and clinical data was not submitted. Performance testing showed that the subject device meets design specifications and performs 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}------------------------------------------------ ## DEPARTMENT OF HEALTH & HUMAN SERVICES Image /page/2/Picture/1 description: The image shows the logo for the U.S. Department of Health & Human Services.
