Intended Use
The envelope is intended to hold a vagus nerve stimulator, a spinal cord neuromodulator, a deep brain stimulator or a sacral nerve stimulator securely in order to create a stable environment when implanted in the body. The envelope contains the antimicrobial agents, rifampin and minocycline, which have been shown 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 or deep brain stimulators implanted in the infraclavicular fossa, or in conjunction with spinal cord neuromodulators or sacral nerve stimulators implanted laterally to the body midline and slightly superior to the gluteal region.
Device Description
TYRX™ Neuro Absorbable Antibacterial Envelope (TYRX Neuro Envelope or the envelope) is a sterile prosthesis comprised of two components; an absorbable substrate mesh, and an absorbable tyrosine based polyarylate polymer containing the antimicrobial agents, rifampin and minocycline, and is designed to hold a vagus nerve stimulator, a spinal cord neuromodulator, a deep brain stimulator, or a sacral nerve stimulator securely to create a stable environment when the device is implanted in the body. The TYRX Neuro Envelope is constructed of multifilament knitted mesh composed of glycolide, caprolactone, and trimethylene carbonate polymer, which is coated with an absorbable polyarylate polymer containing the drug substances rifampin and minocycline. Like its predicate device, the TRYX Neuro Envelope is supplied in two sizes, a 2.5 in. x 2.7 in. (Medium), and a 2.9 in. x 3.3 in. (Large). The appropriate size should be selected based on the external dimensions of the vagus nerve stimulator, the spinal cord neuromodulator, the deep brain stimulator, or the sacral neuro stimulator that is to be implanted.
More Information

No
The device description focuses on the physical structure and antimicrobial properties of an envelope designed to hold implanted nerve stimulators. There is no mention of any computational or analytical functions, let alone AI/ML.

No.
The device acts as an envelope to hold other therapeutic devices (nerve stimulators/neuromodulators) and provides an antimicrobial environment, but it does not directly perform a therapeutic function on the patient. Its primary role is to secure and protect another medical device, and its antibacterial agents are for preventing infection related to that device's implantation.

No

Explanation: The device is an absorbable antibacterial envelope designed to hold implanted neurostimulators securely and create a stable environment, not to diagnose medical conditions. Its function is to prevent infection and stabilize therapeutic devices.

No

The device description clearly states it is a sterile prosthesis comprised of physical components (absorbable substrate mesh, absorbable polymer) and contains antimicrobial agents. It is a physical implantable device, not software.

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

Here's why:

  • IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
  • Device Function: The description clearly states the device is an "absorbable antibacterial envelope" intended to "hold a vagus nerve stimulator, a spinal cord neuromodulator, a deep brain stimulator or a sacral nerve stimulator securely in order to create a stable environment when implanted in the body." It also contains antimicrobial agents to reduce infection risk at the implant site.
  • No Sample Analysis: The device does not analyze any samples taken from the body. Its function is purely mechanical support and local drug delivery at the implant site.

Therefore, the TYRX Neuro Absorbable Antibacterial Envelope is an implantable medical device, not an in vitro diagnostic.

Device Description

TYRX™ Neuro Absorbable Antibacterial Envelope (TYRX Neuro Envelope or the envelope) is a sterile prosthesis comprised of two components; an absorbable substrate mesh, and an absorbable tyrosine based polyarylate polymer containing the antimicrobial agents, rifampin and minocycline, and is designed to hold a vagus nerve stimulator, a spinal cord neuromodulator, a deep brain stimulator, or a sacral nerve stimulator securely to create a stable environment when the device is implanted in the body.

The TYRX Neuro Envelope is constructed of multifilament knitted mesh composed of glycolide, caprolactone, and trimethylene carbonate polymer, which is coated with an absorbable polyarylate polymer containing the drug substances rifampin and minocycline.

Like its predicate device, the TRYX Neuro Envelope is supplied in two sizes, a 2.5 in. x 2.7 in. (Medium), and a 2.9 in. x 3.3 in. (Large). The appropriate size should be selected based on the external dimensions of the vagus nerve stimulator, the spinal cord neuromodulator, the deep brain stimulator, or the sacral neuro stimulator that is to be implanted. Details for the TYRX Neuro Envelopes are provided below.

Indications for Use

There are no changes to the Indications for Use as a result of this submission. The Indications for Use are provided below:

The envelope is intended to hold a vagus nerve stimulator, a spinal cord neuromodulator, a deep brain stimulator or a sacral nerve stimulator securely in order to create a stable environment when implanted in the body.

The envelope contains the antimicrobial agents, rifampin and minocvcline, which have been shown to reduce infection in an in vivo model of bacterial challenge following surgical implantation of a pulse generator. The envelope is intended to be used in conjunction with vagus nerve stimulators or deep brain stimulators implanted in the infraclavicular fossa, or in conjunction with spinal cord neuromodulators or sacral nerve stimulators implanted laterally to the body midline and slightly superior to the gluteal region.

Technological Characteristics

TYRX Neuro Envelope is a biocompatible, sterile device intended to hold a vagus nerve stimulator, a spinal cord neuromodulator, a deep brain stimulator or a sacral nerve stimulator

5

securely in order to create a stable environment when implanted in the body. TYRX Neuro Envelope is identical to its predicate device, cleared under K180122. The further extension of product shelf life presented in this submission does not impact the technical characteristics of the device as compared to the predicate device.

Summary of Testing

Extension of the TYRX Neuro Envelope shelf life is supported by stability study data collected per ICH guidelines. Results of this study demonstrate the TYRX Neuro Envelope, both medium and large size, continue to meet all product requirements through the proposed shelf life. There are no changes to the finished product analytical testing requirements as a result of the modifications described in this submission. The extended shelf life TYRX Neuro Envelope design, materials, mechanism of action, patient contact and intended use are the same as the predicate device.

Substantial Equivalence

Substantial equivalence of the TYRX Neuro Envelope with the proposed shelf life is based on ICH stability studies conducted using the dual foil pouch package with desiccant. Other minor manufacturing changes have been incorporated per Quality System processes. There are no changes to the finished product TYRX Neuro Envelope analytical testing requirements, design, materials, mechanism of action, patient contact or intended use associated with the extended shelf life. The individual and cumulative impact of these changes does not alter the risk profile of the TYRX Neuro Envelopes. The modified device meets the same finished goods acceptance criteria, using the same analytical test methodologies, as the currently marketed device. Therefore, the TYRX Neuro Envelope device, as modified with extended shelf life, is substantially equivalent to the predicate device.

Conclusion

The TYRX Neuro Absorbable Antibacterial Envelope, as modified is substantially equivalent to the predicate device.

Overall, these modifications do not affect the intended use of the device or alter the fundamental scientific technology. There are no changes to the physical design, principles of operation, or mechanism of action of the current TYRX Neuro Envelope.
