The device description and performance studies focus on the physical properties and functionality of a glass tube and silicone washer for lacrimal system repair. There is no mention of software, algorithms, or data processing that would indicate the use of AI or ML.
Yes
The device is intended for use during repair of the lacrimal system for intubation and bypass to canalicular pathologies, which directly addresses a medical condition or abnormality, characterizing it as a therapeutic device.
No
The device is described as being used for "intubation and bypass to canalicular pathologies" during repair of the lacrimal system, which indicates a therapeutic or restorative function, not a diagnostic one.
No
The device description clearly states it is a physical assembly consisting of a glass tube and silicone washer, which are hardware components.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is "during repair of the lacrimal system for intubation and bypass to canalicular pathologies." This describes a surgical or interventional procedure performed on the patient's body, not a test performed on a sample taken from the patient's body.
- Device Description: The device is a physical tube and washer intended for insertion into the lacrimal system. This is a medical device used for treatment or support, not for diagnostic testing.
- Lack of Diagnostic Elements: There is no mention of the device being used to analyze a sample (like blood, urine, tissue, etc.) or to provide information about a patient's health status based on such analysis.
IVD devices are specifically designed to perform tests on samples taken from the human body to provide information for diagnosis, monitoring, or screening. This device does not fit that description.

Summary of Performance Studies
The following non-clinical bench tests were performed: The strength of the bond between the glass tube and the silicone washer using calibrated Instrom equipment was evaluated during stability testing. A pig nose model was used to establish the internal low profile for intubation of the lacrimal anatomy. Sterilization validation has been performed to assure the SAL of 10-6, and packaging and shelf life testing allows for labeling the device with a 5-year shelf life. The device was tested to assure maintenance of integrity after shipping (a transportation validation study). The device was also tested to assure it is non-pyrogenic. Biocompatibility of the materials and the final device have been presented in the 510(k).

Dear Ms. Trisler:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food. Drug. and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

The device was tested to assure maintenance of integrity after shipping (a transportation validation study).
The device was also tested to assure it is non-pyrogenic.
Biocompatibility of the materials and the final device have been presented in the 510(k).
- Comparison to the The StopLoss Jones Tube has the same intended use and the Predicate Devices: same principles of operation as both predicates. The materials used are the same as the borosilicate glass and silicone used to make the predicate devices.
The primary technological differences are that the StopLoss tube was designed with a silicone safety washer/flange which is not present on either predicate.
This difference does not introduce new types of questions of safety and effectiveness. The testing performed on the integrity of the flange and bond strength sufficiently addresses this difference.
Substantjal The comparisons and study data presented in the 510(k) lead to Equivalence the conclusion that StopLoss Jones Tube is substantially Conclusion: equivalent to the predicate devices.
