Intended Use
TephaFLEX braided sutures are indicated for use in general soft tissue approximation and/or ligation, but not for use in cardiovascular or neurological tissues, microsurgery or ophthalmic surgery.
Device Description
TephaFLEX suture is a sterile, braided, surgical suture constructed of poly-4-hydroxybutyrate (P4HB). The suture consists of an inner core of multifilament fibers covered by a braided sheath made of multifilament fibers. The suture is provided dyed (D&C Violet No. 2) or un-dyed and is offered in a variety of cut lengths, with or without needles attached.
More Information

Not Found

No
The device description and performance studies focus on the physical and mechanical properties of a surgical suture, with no mention of AI or ML technologies.

No.
The device is a surgical suture used for approximation and/or ligation of soft tissue, which is a supportive rather than a therapeutic function.

No.
The device description and intended use clearly state that TephaFLEX suture is used for "general soft tissue approximation and/or ligation," which are surgical procedures, not diagnostic ones. The performance studies focus on mechanical properties and biocompatibility, not the detection or diagnosis of conditions.

No

The device description clearly states it is a sterile, braided, surgical suture constructed of poly-4-hydroxybutyrate (P4HB), which is a physical material, not software. The performance studies also focus on physical and mechanical properties of the suture.

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

Here's why:

  • Intended Use: The intended use is for "general soft tissue approximation and/or ligation." This describes a surgical procedure performed on the body, not a test performed outside the body on a sample.
  • Device Description: The device is a "sterile, braided, surgical suture." This is a physical implant used during surgery.
  • 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 or measuring substances in samples
    • Providing information for diagnosis, monitoring, or screening

IVDs are used to perform tests on samples taken from the body to provide information about a person's health status. This device is a surgical tool used to repair tissue.

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

Physical/mechanical testing performed on the TephaFLEX suture verified conformance to USP 33 for absorbable surgical sutures, including Suture Diameter, Knot Pull Tensile Strength, and Needle Attachment Strength.

Testing was also performed for conformance to ISO-10993 for biocompatibility. Tepha performed Cytotoxicity, Intracutaneous Irritation, Sensitization, Acute Systemic Toxicity, Pyrogenicity, Genotoxicity, and 12, 26, 52 and 78 week Subcutaneous Implantation studies in rabbits. All testing yielded a non-toxic response.

In vivo implantation studies were conducted in rabbits to demonstrate rates of tensile strength and mass loss. Results show the in vivo strength retention of the TephaFLEX braided suture to be equivalent to the published strength retention of the predicate devices with the same clinical indications over the critical healing period. Therefore, the TephaFLEX braided suture is equivalent to the predicate device in regard to its strength retention profile.

Physical/mechanical testing performed on the TephaFLEX suture verified conformance to USP 33 for absorbable surgical sutures, including Suture Diameter, Knot Pull Tensile Strength, and Needle Attachment Strength.

Testing was also performed for conformance to ISO-10993 for biocompatibility. Tepha performed Cytotoxicity, Intracutaneous Irritation, Sensitization, Acute Systemic Toxicity, Pyrogenicity, Genotoxicity, and 12, 26, 52 and 78 week Subcutaneous Implantation studies in rabbits. All testing yielded a non-toxic response.

In vivo implantation studies were conducted in rabbits to demonstrate rates of tensile strength and mass loss. Results show the in vivo strength retention of the TephaFLEX braided suture to be equivalent to the published strength retention of the predicate devices with the same clinical indications over the critical healing period. Therefore, the TephaFLEX braided suture is equivalent to the predicate device in regard to its strength retention profile.

Conclusion:

Based on the indications for use, technological characteristics, and the results of safety and performance testing described above, the TephaFLEX braided suture has been shown to be substantially equivalent to predicate devices used for the same clinical indications 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 10 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 cither 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 CFR Part 807); labeling (21 CFR Part 801); medical device reporting (reporting of medical
