Intended Use
The adeor® Meridian™ Cranial Perforator is a sterile, single-use cutting accessory intended for cranial burr-hole trephination in neurological surgery. The Meridian™ Perforator is a single-use surgical device for cranium perforation. The device automatically releases and stops perforating at cranial bone thickness of at least 3 mm. The Meridian™ pediatric perforator version automatically releases and stops perforating at cranial bone thickness of at least 1.5 mm. The perforators are available in three sizes: for burr-hole diameters of 6 mm, 7 mm and 11 mm.
Device Description
The Meridian™ Cranial Perforator is a sterile packed, single-use cutting device intended to perform cranial burr-hole trephination in neurosurgery, driven by powered sources having a standardized and commonly used Hudson fitting clutch. The device automatically releases and stops perforating at cranial bone thickness of at least 3 mm. The Meridian™ pediatric perforators automatically release and stop perforating at cranial bone thickness of at least 1.5 mm. Both versions are available for burr-hole diameters of Ø6. Ø7 and Ø11 mm. The Meridian™ Cranial Perforator per CFR. Part 882.4305, is a bone cutting and drilling instrument driven by a pneumatic or electric surgical motor in order to drill burr-holes through the skull of a patient. An integrated clutch mechanism prevents plunging of the perforator tip into the underlying dura and parenchyma tissue. The device is a Class II (USA) device and classified IIa in Europe (EEC). The Meridian™ Cranial Perforator is a device similar in design and construction to other cranial perforators currently on the market; (e.g.: Acra-Cut models DGR-II and Codman Disposable Perforators etc ... ) The Meridian™ Cranial Perforator requires a motor and an attached or integrated speed reducer in order to run the perforators at a speed range of 800 ... 1200 RPM.

No
The description focuses on a mechanical release mechanism based on bone thickness, not on data-driven learning or inference.

No.
A therapeutic device is typically involved in treating a disease or condition, reducing symptoms, or restoring function. This device is a surgical cutting accessory used to create burr-holes, which is a preparatory step for other neurological procedures, not a therapeutic action itself.

No

This device is a surgical cutting accessory used for cranial burr-hole trephination. It is used to create holes in the skull, not to diagnose a condition.

No

The device is a physical cutting accessory intended for cranial surgery, driven by a motor. It is explicitly described as a "single-use cutting accessory" and a "single-use surgical device."

Based on the provided text, the adeor® Meridian™ Cranial Perforator is not an IVD (In Vitro Diagnostic) device.

Here's why:

  • Intended Use: The intended use is for "cranial burr-hole trephination in neurological surgery." This is a surgical procedure performed directly on a patient's body.
  • Device Description: The device is described as a "single-use cutting accessory intended to perform cranial burr-hole trephination in neurosurgery." It is a mechanical tool used for drilling bone.
  • Mechanism of Action: The device works by physically cutting and drilling through the skull. It has a mechanical release mechanism.
  • Anatomical Site: The anatomical site is the "cranium," which is part of the patient's body.
  • Performance Studies: The performance studies involve drilling holes in wood, animal bone, and animal cadavers. These are not in vitro diagnostic tests performed on biological samples outside the body.

In Vitro Diagnostic (IVD) devices are used to examine specimens (like blood, urine, or tissue) taken from the human body to provide information for diagnosis, monitoring, or screening. The Meridian™ Cranial Perforator does not perform any such analysis of biological samples. It is a surgical instrument used for a physical procedure.

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

Performance Bench Testing:
Samples of each model were used to drill holes in wood and animal bone to verify its mechanical functionality similar to predicate devices. The release mechanism worked reliable on both materials and stopped cutting as soon as the thin remaining pad of material became elastic.

On animal cadavers (pig head and calf shoulder) the release mechanism worked reliable and a clear bone pad has been formed which can easily be removed from the bur-hole. All tests have been performed satisfactory with the following positive remarks: The release mechanism worked reliable on several bur-holes. There was no friction observed between the rotating cutting parts. There has been no skidding of the subject device on the animal cadaver bone. A firm axial rotation and no wobbling of the subject device have been observed. A plain and even surface of the perforated bone and on the bone flap was observed. (See "Performance Bench testing protocol" for details in Chapter 18)

The technological characteristics of the subject device are based on the same cranial perforator technology as the predicate devices. Substantial equivalence of the Meridian™ Adeor cranial perforator is based upon the comparison to predicate device's characteristics.

Performance Standards:

Performance standards have not been established by the FDA under Section 514 of the Federal Food, Drug and Cosmetic Act.

Performance testing:

Substantial equivalence of the Meridian™ Adeor cranial perforator is based upon the comparison to predicate device's technical characteristics, indications, principle of operations, materials, design, and sterile supply as a single-use medical device.

Performance Bench Testing:

Samples of each model were used to drill holes in wood and animal bone to verify its mechanical functionality similar to predicate devices. The release mechanism worked reliable on both materials and stopped cutting as soon as the thin remaining pad of material became elastic.

On animal cadavers (pig head and calf shoulder) the release mechanism worked reliable and a clear bone pad has been formed which can easily be removed from the bur-hole. All tests have been performed satisfactory with the following positive remarks: The release mechanism worked reliable on several bur-holes.
