Used by surgeons in clinical settings during plastic and reconstructive procedures. Implants are carvable to allow customization to patient anatomy. Device provides structural contouring; benefits include aesthetic improvement and reconstruction of body areas. No electronic or software components. ## Clinical Evidence Bench testing only. Testing included sterilization validation, appearance, dimensional inspection, hardness (ASTM D2240), tensile/elongation/tear strength (ASTM D412, D624), and biocompatibility (ISO 10993-3, -5, -6, -10, -11, -23). ## Technological Characteristics Material: Implant-grade silicone elastomer. Form factor: Pre-shaped implants for various body regions (nasal, malar, chin, gluteal, calf, pectoral, block, temple). Mechanical properties verified via ASTM D2240 and ASTM D412. Sterilization: Validated. No energy source or software. ## Regulatory 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. ## Predicate Devices - SOFTXIL ([K171851](/device/K171851.md)) ## Reference Devices - Gluteal Implant, models RND 5-X, TRD 6-X ([K052504](/device/K052504.md)) - Calf Implant, model EC17-X ([K052505](/device/K052505.md)) - Pectoralis Implant ([K952708](/device/K952708.md)) - Customized Contour Implant ([K200610](/device/K200610.md)) ## Related Devices - [K222748](/device/K222748.md) — ShiNeo Silicone Implant · Shineo Technology Co., Ltd. · Dec 23, 2022 - [K223051](/device/K223051.md) — Pre-Formed Silicone Block · International Medical Devices, Inc. · Feb 3, 2023 - [K974480](/device/K974480.md) — SILIMED CALF IMPLANT · Silimed, LLC · Feb 24, 1998 - [K090803](/device/K090803.md) — HANSON MEDICAL FACIAL IMPLANTS · Hanson Medical, Inc. · Jun 30, 2010 - [K200610](/device/K200610.md) — Customized Contour Implant · Implantech Associates, Inc. · Dec 23, 2020 ## Submission Summary (Full Text) {0}------------------------------------------------ Image /page/0/Picture/0 description: The image contains the logo of the U.S. Food and Drug Administration (FDA).

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. --- **Source:** [https://fda.innolitics.com/submissions/SU/subpart-d%E2%80%94prosthetic-devices/MIB/K241150](https://fda.innolitics.com/submissions/SU/subpart-d%E2%80%94prosthetic-devices/MIB/K241150) **Published by [Innolitics](https://innolitics.com)** — a medical-device software consultancy.
