Intended Use
The TephaFLEX® mesh is intended to reinforce soft tissue where weakness exists in patients undergoing plastic and reconstructive surgery, or for the repair of hernia or other fascial defects that require the addition of a reinforcing or bridging material to obtain the desire surgical result.
Device Description
The TephaFLEX mesh is a resorbable mesh prepared from poly-4- hydroxybutyrate (P4HB). The mesh is prepared from undyed, size 5-0 monofilament P4HB fiber that is knitted into a surgical mesh. It is provided in single sheets of varying widths and lengths and may be cut to the shape or size desired for a specific application.

No
The device description and performance studies focus on the material properties and mechanical performance of a resorbable mesh, with no mention of AI or ML technologies.

No.
The device is a mesh intended to reinforce soft tissue and repair defects, providing structural support rather than directly treating a disease or condition.

No
Explanation: The TephaFLEX® mesh is described as a resorbable mesh intended to reinforce soft tissue or repair defects during surgery. Its function is to provide structural support, not to diagnose a condition.

No

The device description clearly states it is a resorbable mesh prepared from a material and knitted into a surgical mesh, indicating it is a physical hardware device, not software.

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

Here's why:

  • Intended Use: The intended use clearly states that the device is for reinforcing soft tissue and repairing defects in patients undergoing surgery. This is an in-vivo application, meaning it is used within a living organism.
  • Device Description: The description details a surgical mesh made from a resorbable material, designed to be implanted.
  • Lack of IVD Characteristics: There is no mention of the device being used to examine specimens derived from the human body (like blood, urine, tissue samples, etc.) to provide information for diagnosis, monitoring, or treatment.

IVD devices are used outside the body to analyze samples and provide diagnostic information. The TephaFLEX® mesh is a surgical implant used inside the body for structural support.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

Mechanical and in vivo animal testing was performed based on recommendations identified in the FDA surgical mesh guidance document: The Guidance for the Preparation of a Pre-market Notification Application for a Surgical Mesh. Specifically, comparative burst strength, suture pull-out strength, tensile strength and tear resistance strength was characterized. In vivo strength retention was characterized via a subcutaneous implantation study. The mechanical and in vivo data collected determined the mesh to be substantially equivalent to the predicate devices.

Contact Person:Mary P. LeGraw, V.P., Regulatory Affairs
Device Classification Name:CFR §878.3300
Surgical Mesh
Classification:According to Section 13 of the Federal Food, Drug and Cosmetic Act, the
device classification is Class II, Performance Standards.
Predicate Devices:TephaFLEX® Surgical Mesh
TephaFLEX® Composite Mesh
SupraMESH EXTRA™
Device Description:The TephaFLEX mesh is a resorbable mesh prepared from poly-4-
hydroxybutyrate (P4HB). The mesh is prepared from undyed, size 5-0
monofilament P4HB fiber that is knitted into a surgical mesh. It is
provided in single sheets of varying widths and lengths and may be cut to
the shape or size desired for a specific application.
Indications for UseTephaFLEX mesh is intended to reinforce soft tissue where weakness
exists in patients requiring soft tissue repair or reinforcement in plastic
and reconstructive surgery, or for the repair of hernia or other fascial
defects that require the addition of a reinforcing or bridging material to
obtain the desire surgical result.
Safety and Performance:Mechanical and in vivo animal testing was performed based on
recommendations identified in the FDA surgical mesh guidance
document: The Guidance for the Preparation of a Pre-market Notification
Application for a Surgical Mesh. Specifically, comparative burst strength,
suture pull-out strength, tensile strength and tear resistance strength was
characterized. In vivo strength retention was characterized via a
subcutaneous implantation study. The mechanical and in vivo data
collected determined the mesh to be substantially equivalent to the
predicate devices.
Conclusion:Based on the indications for use, technological characteristics, and safety
and performance testing, the TephaFLEX mesh has been shown to be
substantially equivalent to predicate devices under the Federal Food,
Drug and Cosmetic Act.

Dear Ms. LeGraw:

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 (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. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21
