The device description and intended use focus solely on the physical properties and function of a tissue marker implant. There is no mention of any software, algorithms, or data processing that would suggest the use of AI or ML. The "Mentions AI, DNN, or ML" and "Mentions image processing" sections are explicitly marked as "Not Found".
No.
The device's stated intended use is to "radiographically mark soft tissue during a surgical procedure or for future surgical procedures," which serves a diagnostic or localization purpose rather than directly treating or preventing a disease or condition.
No
Explanation: The device is indicated for marking soft tissue for radiographic visualization during or for future surgical procedures, not for diagnosing a disease or condition.
No
The device description clearly states it is a "semi-solid, cohesive subdermal implant" made of physical materials like calcium hydroxylapatite and a gel carrier. This indicates a physical medical device, not a software-only one.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is to "radiographically mark soft tissue during a surgical procedure or for future surgical procedures." This describes a device used in vivo (within the body) to provide a physical marker visible on radiographic imaging.
- Device Description: The description details a "subdermal implant" placed "into soft tissue." This confirms it's an implantable device used within the body.
- IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body (like blood, urine, tissue) to provide information about a person's health. This device does not perform any such testing on samples.
The device is a physical marker implanted in the body, not a diagnostic test performed on a sample outside the body.

Device Description
Sterile, latex free, non-pyrogenic, semi-solid, cohesive subdermal implant. The principle durable component is synthetic calcium hydroxylapatite. The semi-sold nature is created by suspending the calcium hydroxylapatite particles in a durable high yield strength thixotropic gel. The isotonic gel carrier consists primarily of sterile water for injection (USP), glycerin (USP) and mannitol (USP). The thixotropic high yield strength gel is created by the Carbopol 974P NF (USP). Cytophil Tissue Marker is placed into soft tissue during open, percutaneous, or endoscopic procedures to radiographically mark a surgical location. There is no ferrous material used in the formulation of the Cytophil Tissue Marker. However, the safety and efficacy of the Ctyophil Marker has not been established for Computer Tomography, Ultrasonography or Magnetic Resonance Imaging.

4.3 Substantial Equivalence
The following is the predicate device that is substantially equivalent to the Cytophil Tissue Marker:
K012955 Coaptite Tissue Marker and Coaptite FN Tissue Marker BioForm Medical, Inc. 1875 South Grant St., Suite 110 San Mateo, CA 94402
The Cytophil Tissue Marker is substantially equivalent to BioForm's Coaptite Tissue Marker and Coaptite FN Tissue Marker which functions as a radiographic soft tissue marker.
4.4 Biocompatibility Evaluations
The battery of preclinical safety studies and animal implant studies show that the Cytophil Tissue Marker is biocompatible when injected into soft tissues.
4.5 Sterilization
Cytophil Tissue Marker is sterilized using steam. Processing is preformed by a contract sterilization company. Haemonetics, using a computer controlled autoclave system. Cycle parameters were validated using an overkill methodology to 10 ° SAL. Sterilization by the user is not required.
4.6 Pre-Clinical Tests Performed
In vivo and in vitro tests were performed to address irritation, sensitization, cytotoxicity, acute and sub-chronic toxicity, genotoxicity and hemolysis. Results identified the Cytophil Tissue Marker as a nonirritant, and nontoxic with no concerns for long-term safety.
