No
The device description and performance studies focus on the physical and functional aspects of a manual suction curette, with no mention of software, algorithms, or data processing that would indicate AI/ML.
No
The device is used to obtain tissue samples for biopsy and screening, which are diagnostic purposes. While these diagnoses may lead to therapeutic interventions, the device itself is not performing a therapeutic function.
Yes
The device obtains tissue samples for purposes of "biopsy precancer screening," which is a diagnostic activity aimed at detecting diseases.
No
The device description clearly outlines physical components (tube, piston, O-ring) made of materials like polypropylene and silicone, and the performance studies focus on physical and functional testing of these components, not software.
Based on the provided information, the "RELIEEV" Suction Curette is not an In Vitro Diagnostic (IVD) device.
Here's why:
- IVD devices are used to examine specimens obtained from the human body to provide information for diagnostic purposes. This typically involves tests performed outside the body (in vitro).
- The "RELIEEV" Suction Curette is a surgical instrument used to obtain the specimen from the body. Its function is to physically remove tissue samples from the uterus.
- The intended use describes obtaining tissue samples for biopsy and precancer screening. While these samples will likely be used for in vitro diagnostic testing later (e.g., pathology examination), the curette itself is the tool for collection, not the diagnostic test itself.
Therefore, the "RELIEEV" Suction Curette is classified as a surgical instrument or device used for tissue collection, not an IVD.
