Intended Use
MISTI Silicone Implant is intended for the augmentation of the nasal, malar, chin, gluteal, calf and/or pectoral contour.
Device Description
The MISTI Silicone Implant offers various types including Nasal, Chin, Mid-face, Forehead, Block, Temple, Gluteal, Calf and Pectoral. The Nasal, Chin, Mid-face, Forehead, Gluteal, Calf and Pectoral are used for the areas indicated in the type names. The Block type is used for various areas during plastic and reconstruction surgeries. The Temple type can be used on a juncture where four skull bones fuse together so called the temple region. It is made of implant grade silicone elastomer, and the design characteristic minimizes carving and promotes natural line.
More Information

No
The summary describes a physical silicone implant and does not mention any software, algorithms, or data processing that would indicate the use of AI/ML.

No
The device is described as an implant for augmentation of various body contours, not for treating a disease or injury.

No

The device is an implant for augmenting body contours, not for diagnosing medical conditions. The performance studies listed are for material properties and biocompatibility, not diagnostic accuracy.

No

The device description explicitly states it is made of "implant grade silicone elastomer," indicating it is a physical hardware device, not software. The performance studies also focus on physical properties and biocompatibility of the material.

No, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use clearly states the device is for the "augmentation of the nasal, malar, chin, gluteal, calf and/or pectoral contour." This describes a surgical procedure performed on the body, not a test performed on samples taken from the body.
  • Device Description: The description details a silicone implant designed to be placed within the body for cosmetic or reconstructive purposes.
  • Lack of IVD Characteristics: There is no mention of analyzing samples (blood, urine, tissue, etc.), detecting substances, or providing diagnostic information based on laboratory tests. The performance studies listed are related to the physical and biological compatibility of the implant material, not diagnostic accuracy.

IVD devices are used to examine specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes. This device is a physical implant used for structural augmentation.

(a)
Identification. Ear, nose, and throat synthetic polymer material is a device material that is intended to be implanted for use as a space-occupying substance in the reconstructive surgery of the head and neck. The device is used, for example, in augmentation rhinoplasty and in tissue defect closures in the esophagus. The device is shaped and formed by the suregon to conform to the patient's needs. This generic type of device is made of material such as polyamide mesh or foil and porous polyethylene.(b)

Dear Priscilla Chung:

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 (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. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products.

8.2. Substantial Equivalence Discussion

The MISTI Silicone Implant is substantially equivalent in material, design, function, and performance to predicate devices. We identified the reference devices for different areas to be used on patients.

All products have identical intended uses and are offered in similar shapes and sizes. The size might be different between the devices, however, since the physician can carve or cut the material to fit each patient so that this difference does not raise an issue of safety and performance.

We have performed the performance and biocompatibility tests and the test results support that the subject device is substantially equivalent to the predicate devices in the market.

Conclusion: 9.

Based on the information submitted herein, KEOSAN TRADING CO. concludes that the MISTI Silicone Implant is substantially equivalent to the predicate device.
