Intended Use
The GSI, Inc. Mammary Sizer is intended to assist in evaluation of the appropriate mammary prosthesis volume for each patient prior to implantation.
Device Description
The GSI Mammary Sizer is designed to be used during plastic and reconstructive surgery when it is desirable to determine the correct volume and/or symmetry of mammary implants prior to implantation. The device is constructed of smooth semi-elastomeric polyurethane. The device consists of a balloon and balloon tubing used for filling the sizer. There is an attachment to prevent fluid leakage and a female luer lock at the proximal end of the filler tube.

No
The device description and performance studies focus on physical properties and volume measurement, with no mention of AI/ML terms or data processing.

No.
The device is a sizer used to determine the appropriate volume and symmetry of mammary implants prior to implantation, not for treating a disease or condition.

No

Explanation: The device is used to determine the appropriate volume and symmetry of mammary implants prior to implantation, which is a pre-surgical sizing aid, not a diagnostic tool for identifying a disease or condition.

No

The device description explicitly states the device is constructed of physical materials (polyurethane) and includes physical components (balloon, tubing, luer lock). It is a physical medical device, not software-only.

Based on the provided information, the GSI, Inc. Mammary Sizer is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
  • Mammary Sizer Function: The Mammary Sizer is a physical device used during surgery to help determine the appropriate size of a mammary implant in vivo (within the living body). It is not used to analyze a sample taken from the patient.
  • Intended Use: The intended use clearly states it's to "assist in evaluation of the appropriate mammary prosthesis volume for each patient prior to implantation," which is a surgical procedure.

Therefore, the GSI Mammary Sizer falls under the category of a surgical device, not an in vitro diagnostic device.

Substantial Equivalence and Conclusions

The Mammary Sizer which is proposed for use in the sub-glandular of sub-muscular tissue plane is substantially equivalent to Mentor's Volume Sizer for Mammary Implants that are marketed for use in the area of plastic and reconstructive surgery.

Intended Use

The GSI, Inc. Mammary Sizer is intended to assist in evaluation of the appropriate mammary prosthesis volume for each patient prior to implantation.
