Intended Use
Silgel is intended for use in the management of hypertrophic and keloid scars, prophylactic management of healed incisions and as a splint lining insert to relieve friction on newly healed scars.
Device Description
Silgel, Topical Gel Sheet, consists of durable medical grade silicone reinforced with polyester mesh. Sheets are protected on one side by a film which is removed before use and on the other by a paper backing. Sheets are individually packaged in grip seal bags. A sheet can be trimmed to the desire shape prior to placement on the scar. It is secured by wrapping with either gauze and hypoallergenic adhesive tape, light conforming crepe or tubular bandages, or compression garments. Firm pressure in not required for a therapeutic effect.
More Information

No
The device description and intended use are for a topical silicone gel sheet for scar management, with no mention of AI or ML technology.

Yes
The intended use explicitly states its purpose in the "management of hypertrophic and keloid scars" and "prophylactic management of healed incisions," which are therapeutic applications.

No

Explanation: The device description for Silgel focuses on its physical properties and how it's applied to manage scars, not on diagnosing medical conditions. Its intended use is for the management and prophylactic management of scars, not for diagnosis.

No

The device description clearly states that Silgel is a "Topical Gel Sheet" made of "durable medical grade silicone reinforced with polyester mesh." This describes a physical, material-based device, not software.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use of Silgel is for the management and prophylaxis of scars. This is a therapeutic application, not a diagnostic one. IVDs are used to examine specimens from the human body to provide information for diagnosis, monitoring, or screening.
  • Device Description: The device is a topical gel sheet applied externally to the skin. It does not involve the analysis of biological samples.
  • Lack of IVD Characteristics: The description does not mention any of the typical characteristics of an IVD, such as:
    • Analyzing biological samples (blood, urine, tissue, etc.)
    • Detecting specific analytes or biomarkers
    • Providing diagnostic information

Therefore, Silgel falls under the category of a medical device used for wound care and scar management, not an in vitro diagnostic device.

Intended Use / Indications for Use

Summary of Performance Studies

Component Testing: The silicone gel raw material, cured under conditions similar to those used for the finished device, has been subjected to the blocompatibility tests as defined in ISO 10933 for skin-contact devices. The biocompatibility data demonstrate that the silicone gel meets all test requirements.

Final Product Testing: Final product configuration was subjected to the following test battery.
Hemolysis Test: In Vitro Hemolysis Test by Direct Contact
Cytotoxity Test: MEM Elution Method
Pyrogenicity Test: Limulus Amebocyte Lysate (LAL) Test
All tests were acceptable demonstrating that the product is safe for its intended use.

The effectiveness of silicone gel sheet products in the management and prophylaxis of hypertrophic and keloid scars has been demonstrated by numerous clinical studies. The intended use and instructions for use for Silgel are consistent with the clinical findings of these studies.

6. Technological Characteristics

Silgel and the predicate devices consist of a thin sheet of silicone gel. Silge! and several of the predicate devices contain a reinforcing mesh, while Cicacare is supported by a silicone membrane. All products are conformable, semi-occlusive, slightly adhesive and durable. Although the mechanism of action is not completely characterized, the effectiveness of silicone gel sheeting products has been repeatedly demonstrated in the clinical situation.

7. Testing Summary

Component Testing:

The silicone gel raw material, cured under conditions similar to those used for the finished device, has been subjected to the blocompatibility tests as defined in ISO 10933 for skin-contact devices. The biocompatibility data demonstrate that the silicone gel meets all test requirements.

Final Product Testing:

Final product configuration was subjected to the following test battery. Hemolysis Test: In Vitro Hemolysis Test by Direct Contact Cytotoxity Test: MEM Elution Method Pyrogenicity Test: Limulus Amebocyte Lysate (LAL) Test

All tests were acceptable demonstrating that the product is safe for its intended use.

The effectiveness of silicone gel sheet products in the management and prophylaxis of hypertrophic and keloid scars has been demonstrated by numerous clinical studies. The intended use and instructions for use for Silgel are consistent with the clinical findings of these studies.

8. Rationale for Substantial Equivalence Determination

A comparison of the technological characteristics of Silgel Topical Gel Sheet shows that it is a silicone gel sheet as are all predicate devices. The intended use in the management of hypertrophic and keloid scars is common with these predicate devices. As with Cica-Care, Silgel is indicated for prophylactic therapy in healed incisions and wounds. It is also indicated as a splint lining to relieve friction on newly healed scars similar to Spenco Silicone Gelsheet. The instructions for use are essentially the same for all products. As with the predicate devices, Silgel can be cleaned routinely during the course of clinical management. All product labels discuss the potential skin complications associated with clinical use including rash and irritation. Unlike predicate devices, Silgel is not provided sterile nor is this considered to be a requirement for product safety and efficacy since it is only intended for use on intact skin. Based on this information, Silgel can be considered substantially equivalent to the predicate devices.
