No
The summary describes a physical device (a plug) made of gelatin and glycerol with a mechanical function (occluding the medullary cavity). There is no mention of software, algorithms, data processing, or any terms related to AI/ML.
No.
The device prevents cement from flowing down the diaphysis and facilitates cement pressurization, which is an adjunctive function during a surgical procedure, not a direct therapeutic effect on a disease or condition.
No
The device is described as a "diaphyseal plug designed to occlude the medullary cavity before the introduction of acrylic cement during total hip arthroplasty." Its function is mechanical (preventing cement flow), not to diagnose a condition or disease.
No
The device description clearly states it is a physical implant fabricated from gelatin and glycerol, designed to be inserted into the femoral canal. This is a hardware device, not software.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices used to perform tests on samples taken from the human body (like blood, urine, tissue) to provide information about a person's health. These tests are performed outside of the body.
- CEMSTOP Function: The CEMSTOP Cement Restrictor is a physical device that is implanted into the body during surgery. Its function is to physically block the flow of cement within the femoral canal. It does not perform any tests on bodily samples.
The description clearly indicates it's a surgical implant used in vivo (within the living body) during a surgical procedure.

Dear Mr. Webb:
This letter corrects our substantially equivalent letter of November 26, 2003.
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.
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must
