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 Story

TephaFLEX Braided Suture is a sterile, absorbable surgical suture composed of poly-4-hydroxybutyrate (P4HB). The device features a multifilament inner core covered by a braided multifilament sheath. It is available in dyed (D&C Violet No. 2) or undyed forms, with or without attached needles. Used by surgeons for soft tissue approximation and ligation, the suture provides extended wound support. The device is absorbed in vivo over time, with strength retention profiles comparable to predicate absorbable sutures. Clinical benefit includes secure tissue approximation during the healing period followed by gradual absorption, reducing the need for suture removal. The device is provided sterile for clinical use.

Clinical Evidence

No human clinical trials were conducted. Evidence consists of bench testing and in vivo animal studies. Bench testing confirmed compliance with USP 33 standards for diameter, knot pull tensile strength, and needle attachment. Biocompatibility testing (ISO 10993) included cytotoxicity, irritation, sensitization, systemic toxicity, pyrogenicity, genotoxicity, and subcutaneous implantation in rabbits (12-78 weeks), showing non-toxic responses. In vivo rabbit studies demonstrated tensile strength retention and mass loss rates equivalent to predicate devices.

Technological Characteristics

Material: Poly-4-hydroxybutyrate (P4HB). Construction: Braided multifilament sheath over multifilament core. Sterilization: Ethylene Oxide (EO). Compliance: USP 33 (diameter, knot pull strength, needle attachment), ISO 10993 (biocompatibility). Packaging: Foil with Tyvek header.

Indications for Use

Indicated for general soft tissue approximation and/or ligation. Contraindicated for cardiovascular, neurological, microsurgery, or ophthalmic procedures.

Regulatory Classification

Identification

An absorbable poly(hydroxybutyrate) surgical suture is an absorbable surgical suture made of material isolated from prokaryotic cells produced by recombinant deoxyribonucleic acid (DNA) technology. The device is intended for use in general soft tissue approximation and ligation.

Special Controls

*Classification.* Class II (special controls). The special control for this device is the FDA guidance document entitled “Class II Special Controls Guidance Document: Absorbable Poly(hydroxybutyrate) Surgical Suture Produced by Recombinant DNA Technology.” For the availability of this guidance document see § 878.1(e).

K132348 page 2/4 99 Hayden Avenue Suite 360 Lexington, MA 02421 tel: (781) 357-1700 fax: (78) 357-1701 Physical/mechanical testing performed on the TephaFLEX suture verified conformance to USP 33 for absorbable surgical sutures, including <861> Suture Diameter, <881> Knot Pull Tensile Strength, and <871> 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. 310 {2}------------------------------------------------ | Characteristic | Tepha, Inc.<br>TephaFLEX Braided Suture | Tepha, Inc.<br>TephaFLEX Absorbable Suture<br>K052225, K081099, K082178 | Ethicon, Inc., Perma-Hand Silk<br>Suture<br>K930360 | Covidien/US Surgical<br>Dexon Braided Suture<br>K972566 | |----------------------------------------------------------------------------------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | Indications for Use | Indicated for use in soft<br>tissue approximation<br>and/or ligation but not for<br>use in cardiovascular or<br>neurological surgery,<br>microsurgery or<br>ophthalmic surgery. | Indicated for use in soft tissue<br>approximation and/or ligation but not<br>for use in cardiovascular or<br>neurological surgery, microsurgery<br>or ophthalmic surgery.<br>These sutures are particularly useful<br>where the combination of an<br>absorbable suture and extended<br>wound support (up to six months) is<br>desirable. | Perma-Hand sutures are indicated<br>for use in general soft tissue<br>approximation and/or ligation,<br>including use in cardiovascular,<br>ophthalmic and neurological<br>procedures. | Braided Dexon S sutures are<br>indicated for use as absorbable<br>sutures in general soft tissue<br>approximation and/or ligation,<br>including use in ophthalmic<br>procedures, but not for use in<br>cardiovascular or neural tissue. | | Material | Poly-4-hydroxybutyrate<br>(P4HB) | Poly-4-hydroxybutyrate (P4HB) | Organic fibroin protein derived<br>from domesticated species<br>Bombyx mor (B. mori).
