The device description and intended use focus on the physical properties and antimicrobial function of an absorbable envelope, with no mention of AI or ML capabilities.
No
The device is an absorbable antibacterial envelope designed to hold other implanted devices (vagus nerve stimulators or spinal cord neuromodulators) and reduce infection. It does not directly treat a disease or condition itself.
No
The device is an absorbable antibacterial envelope designed to hold implanted neuromodulators and reduce infection; it does not diagnose medical conditions.
No
The device description clearly states it is a "fully absorbable, dual component sterile device" constructed of knitted filaments and coated with a polymer mixture containing antimicrobial agents. This describes a physical, implantable medical device, not software.
Based on the provided text, the TYRX™ Neuro Absorbable Antibacterial Envelope is not an IVD (In Vitro Diagnostic) device.
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens taken from the human body (like blood, urine, tissue) to provide information about a person's health. This information is used for diagnosis, monitoring, or screening.
- TYRX™ Neuro Function: The description clearly states the device is intended to hold a vagus nerve stimulator or spinal cord neuromodulator securely when implanted in the body. It also contains antimicrobial agents to reduce infection at the implantation site.
- No Specimen Analysis: There is no mention of this device being used to analyze any biological specimens taken from the patient. Its function is entirely related to supporting and protecting an implanted medical device within the body.
Therefore, the TYRX™ Neuro Absorbable Antibacterial Envelope is an implantable medical device, not an In Vitro Diagnostic device.

AIGISRx N Antibacterial Envelope (K132699) (Primary Predicate)
AIGISRx Resorbable Antibacterial Envelope (K130943)
Device Description:
TYRX ™ Neuro Absorbable Antibacterial Envelope is a fully absorbable , dual component sterile device designed to hold a vagus nerve stimulator or spinal cord neuromodulator securely to create a stable environment when implanted in the body. It is constructed of knitted filaments of a commercially available absorbable polymer, Glycoprene II, comprised of glycolide, caprolactone and trimethylene carbonate polymer, and coated with an absorbable polyarylate polymer mixture containing the antimicrobial agents rifampin and minocycline. Rifampin and minocycline have been shown to reduce infection in an in vivo model of bacterial challenge following surgical implantation of an implantable electronic device is to be used in a healthcare facility/hospital by personnel experienced in the procedure of vagus nerve or spinal cord neuromodulator implantation.
Indications for Use
TYRX TM Neuro Absorbable Antibacterial Envelope is intended to hold a vagus nerve stimulator or spinal cord neuromodulator securely in order to create a stable environment when implanted in the body.
TYRX ™ Neuro Absorbable Antibacterial Envelope contains the antimicrobial agents rifampin and minocycline which have been shown to reduce infection in an in vivo model of bacterial challenge following surgical implantation of a pulse generator. This device is intended to be used in conjunction with vagus nerve stimulators implanted in the infraclavicular fossa, or spinal cord neuromodulators implanted laterally to the body midline and slightly superior to the gluteal region.
TYRX "1" Neuro Absorbable Antibacterial Envelope is intended for single-patient, one-time use only.
5
The Indications for Use statement for TYRX Neuro Absorbable Antibacterial Envelope is identical to the primary predicate. Both devices have the same intended use which is to create a stable environment for a vagus nerve stimulator or spinal cord neuromodulator when implanted.
Comparison of Technological Characteristics with the Predicate Device
TYRX TM Neuro Absorbable Antibacterial Envelope (subject device) is identical in Indication for Use to its predicate, AIGIS N (K132699). Both devices are intended to hold a vagus nerve stimulator or spinal cord neuromodulator securely in order to create a stable environment when implanted in the body. The difference is that TYRX TM Neuro Absorbable Antibacterial Envelope is fully absorbable containing the absorbable Glycoprene II substrate mesh, whereas AIGIS N is partially absorbable; containing the nonabsorbable polypropylene polymer substrate mesh. Both AIGIS N and TYRX Neuro Absorbable Antibacterial Envelope are coated with the identical absorbable polyarylate polymer coating containing the antibiotics rifampin and minocycline in concentrations of 102ug/cm2 .
TYRX ™ Neuro Absorbable Antibacterial Envelope has the same substrate material found in the FDA cleared AIGISRx R (K130943)(predicate for mesh substrate only). Both devices are fully absorbable. The fully absorbable substrate mesh is constructed of knitted filaments of a commercially available absorbable polymer. Glycoprene II, comprised of glycolide, caprolactone and trimethylene carbonate polymer. There is no difference in the manufacturing processes for the subject device. The difference is that the predicate device (K 132699) substrate mesh is composed of polypropylene and the TYRX "" Neuro Absorbable Antibacterial Envelope (subject device) has Glycoprene II as the substrate mesh.
Biocompatability Results
TYRX™ Neuro Absorbable Antibacterial Envelope is supplied sterile, biocompatible, and nonpyrogenic. TYRX follows the ISO 11137 standard for sterility. Bench testing demonstrated that the Glycoprene II mesh degrades into its constituent monomers, and there is no chemical or physical interaction between the Glycoprene mesh, the polyarylate coating or the antibiotics.
Biocompatability testing of the predicate devices in accordance with ISO Standard 10993 demonstrated the biocompatibility and safety of the subject device.

Animal Studies
In in vitro studies, predicates K132699 and K130943 demonstrated antimicrobial activity against Methicillin Resistant Staphylococcus aureus (MRSA), Staphylococcus aureus, Acinetobacter baumannii, Staphylococcus epidermidis; K130943 also demonstrated antimicrobial activity against Staphylococcus lugdunensis and Escherichia coli.
In vivo efficacy testing, previously submitted with the primary predicate, K132699, demonstrated effectiveness in reducing infections. The bacteria tested were Staphylococcus aureus, Acinetobacter baumannii, Staphylococcus epidermidis and Escherichia coli. In vivo efficacy testing, previously submitted with predicate K130943, demonstrated effectiveness in reducing infections with these additional bacteria, methicillin-resistant Staphylococcu aureus (MRSA), and Staphylococcus lugdunensis. It should be noted that the in vivo and in vitro activity of the TYRX "" Antibacterial Envelope antimicrobials is variable against nonepidermidis strains of coagulase-negative Staphylococci.
CONCLUSION:
In summary, the TYRX Neuro Absorbable Antibacterial Envelope is identical in terms of physical construct to the currently marketed AIGIS N (K132699) except that for the subject device, a bioabsorable, multi filament surgical mesh (Glycoprene II) will replace the monofilament polypropylene surgical mesh substrate in the non absorbable predicate device. The polymer coating containing the antibiotics rifampin and minocycline in concentrations of 102µg/cm2 applied to the substrate will remain unchanged. The device is sterile and nonpyrogenic.
Based on the 510(k) summaries and the information provided, we conclude that TYRX ™ Neuro Absorbable Antibacterial Envelope is safe and effective for its intended use, and is substantially equivalent to the predicate device AIGIS N (K132699) from the perspective of Indication for Use and substantially equivalent to the predicate device (AIGIS R, K130943) from the perspective of technological characteristics and shelf life (1 month).
