Intended Use
Mitek meniscal fasteners "H" Fix PDS are intended for use in the repair or torn meniscal tissue in the red/red zone of the meniscus (outer 1/3 ) as well as the repair of a separation of a synovium.
Device Description
Mitek Meniscal Fasteners are molded polymeric implants used to repair tears in the meniscus. Fasteners provide the means for firmly securing together the edges of a tear in the meniscus or across the synovial meniscal junction. The fasteners are available in absorbable PDS (polydioxanone). The "H" Fix is cylindrical in cross section and configured to have one leg of the letter "H" in a 90 degree opposed position to the other.

No
The device description and intended use focus on a physical implant for meniscal repair, with no mention of software, data processing, or AI/ML terms.

Yes.
The device is described as "intended for use in the repair or torn meniscal tissue" and secures "edges of a tear in the meniscus," which are actions that restore or improve a body function, thus making it a therapeutic device.

No

The device is a meniscal fastener, which is an implant used for repairing tears in the meniscus. Its intended use is therapeutic (repairing torn tissue), not for diagnosing conditions.

No

The device description clearly states it is a molded polymeric implant, which is a physical hardware component, not software.

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

Here's why:

  • Intended Use: The intended use is for the repair of torn meniscal tissue and synovial separation within the body. This is a surgical intervention, not a diagnostic test performed on samples outside the body.
  • Device Description: The device is a molded polymeric implant designed to secure tissue edges. This is a physical repair mechanism, not a tool for analyzing biological samples.
  • Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue, etc.), detecting biomarkers, or providing diagnostic information.

IVD devices are used to examine specimens from the human body to provide information for diagnosis, monitoring, or screening. This device is a surgical implant used for physical repair.

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

The Mitek absorbable "H" Fix pull tests from cadaver meniscus provided an average failure load of 12.06 pounds.

Studies of the polydioxanone polymer have found it to be nonantigenic, nonpyrogenic, and it elicits only a slight tissue response during healing.

The absorption characteristics of polydioxanone have been extensively studied. The general mechanism by which in vivo degradation of polydioxanone occurs is hydrolysis. The in vivo hydrolysis of polydioxanone cleaves the ester linkages and initially results in the loss of tensile strength. Ultimately the hydrolyzed polymer is eliminated from the body, primarily in urine.

Studies conducted on devices made from polydioxanone polymer indicate minimal absorption until about the 90th post-implantation day.

The results of implantation studies of polydioxanone molded articles in animals indicate that approximately 85% of its original strength remains 5 weeks after implantation. At 7 weeks post implantation approximately 12% of its original strength is retained.

§ 888.3040 Smooth or threaded metallic bone fixation fastener.

(a)
Identification. A smooth or threaded metallic bone fixation fastener is a device intended to be implanted that consists of a stiff wire segment or rod made of alloys, such as cobalt-chromium-molybdenum and stainless steel, and that may be smooth on the outside, fully or partially threaded, straight or U-shaped; and may be either blunt pointed, sharp pointed, or have a formed, slotted head on the end. It may be used for fixation of bone fractures, for bone reconstructions, as a guide pin for insertion of other implants, or it may be implanted through the skin so that a pulling force (traction) may be applied to the skeletal system.(b)
Classification. Class II.

PREDICATE DEVICE

ACUFEX "T" FIX DEVICE PDS II SUTURE

DESCRIPTION OF DEVICE FUNCTION

To hold outer 1/3 (meniscal) soft tissue in apposition during the healing time period.

DEVICE DESIGN

The "H" Fix is cylindrical in cross section and configured to have one leg of the letter "H" in a 90 degree opposed position to the other.

MATERIALS USED

The Mitek absorbable "H" Fix is made from PDS (polydioxanone) polymer.

INTENDED USE

The device is surgically placed across (through) a tear in the meniscal tissue of the knee with a needle applicator and released "H" Fix produces a holding (compressive) force across the tear causing tissue apposition, which allows the natural healing process (at the tear) to occur. The tear in the meniscus for repair with the "H" PDS device should be located in the outer 1/3 zone of the meniscus,i.e., red/red zone.

COMPARISON TO PREDICATE DEVICE(S)

The Mitek absorbable "H" Fix device is similar to the Acufex T-Fix device in function. The T-Fix is surgically placed through a tear in the knee meniscus, toggled and then tied with sutures over external tissues to hold the T-Fix in place. The "H" Fix is placed through the tear in a cannulated needle and extended into the tissue, the spring forces in the material are induced by proper placement in the tissue and device length.

DESCRIPTION OF NON CLINICAL TESTS

The Mitek absorbable "H" Fix pull tests from cadaver meniscus provided an average failure load of 12.06 pounds.

CONTENTS

A Meniscal Fastener secured in a delivery needle is supplied sterile unless the package is damaged or opened. Do not re-sterilize PDS (polydioxanone).

INDICATIONS

Mitek Meniscal Fasteners are intended for the repair of torn meniscal tissue in the red/red zone of the meniscus (outer 1/3) as well as the repair of a separation of the meniscus from the synovium.

CONTRAINDICATIONS

These fasteners (being absorbable) are not to be used where prolonged ( beyond 6 weeks) approximation of tissue under stress is required.

PRECAUTIONS

  • Care should be taken to avoid damage when handling the fasteners. Avoid the crushing of 1. the fasteners by the application of needle holders or forceps.
  • A surgeon should not attempt clinical use of the Mitek Meniscal Fasteners before reviewing 2. instructions for use and rehearsing the installation procedure.
  • Users should exercise caution when handling surgical needles to avoid inadvertent needle sticks. 3.
  • Discard used needles in sharps containers. 4.
