Device Facts

• Record ID: K974088
• Device Name: CODMAN INTRACRANIAL BOLT
• Applicant: Johnson & Johnson Professionals, Inc.
• Product Code: GWM · Neurology
• Decision Date: Jan 9, 1998
• Decision: SESE
• Submission Type: Traditional
• Regulation: 21 CFR 882.1620
• Device Class: Class 2

Intended Use

The CODMAN® Intracranial Bolt is indicated for use as a component of an intracranial pressure (ICP) monitoring system designed to achieve direct ICP monitoring. Specifically, the CODMAN® Intracranial Bolt is intended to secure an ICP transducer during direct ICP monitoring in both subdural and intraparenchymal applications.

Device Story

The CODMAN® Intracranial Bolt is a mechanical fixation device used in neurosurgical settings to secure an ICP transducer within the cranium. The assembly consists of a bolt, wing nut, compression cap, compression grommet, washer, and an obturator/dura pierce. The bolt is screwed into the cranium; the compression cap is tightened to compress the grommet, securing the transducer in place. The obturator/dura pierce is used to clear the lumen and pierce the dura prior to transducer insertion. The device facilitates direct ICP monitoring, allowing clinicians to obtain real-time pressure data to guide clinical decision-making in patients with neurological conditions. It is intended for use by physicians in clinical or surgical environments.

Clinical Evidence

No clinical data provided; bench testing only.

Technological Characteristics

Mechanical fixation device. Components: bolt, wing nut, compression cap, compression grommet, washer, obturator/dura pierce. Materials: biocompatible implant materials. Principle: mechanical compression of grommet to secure transducer. Form factor: cranial bolt assembly.

Indications for Use

Indicated for patients requiring direct intracranial pressure (ICP) monitoring via subdural or intraparenchymal applications. Used as a component to secure an ICP transducer.

Regulatory Classification

Identification

An intracranial pressure monitoring device is a device used for short-term monitoring and recording of intracranial pressures and pressure trends. The device includes the transducer, monitor, and interconnecting hardware.

#### Name of Device________________________________________________________________________________________________________________________________________________________________

CODMAN® Intracranial Bolt Proprietary Name: Common Name: Intracranial Bolt Classification Name: Intracranial pressure monitoring device

#### Device Classification

This device has been placed in Class II for intracranial pressure monitoring devices per 21 CFR § 882.1620 (84GWM).

#### Statement of Substantial Equivalence

The CODMAN® Intracranial Bolt is substantially equivalent to both the CODMAN® MicroSensor™ Skull Bolt and Camino ICP Bolt based on the subject device's similarity to the predicate devices in intended use, materials, design, and principles of operation.

#### Indications for Use

The CODMAN® Intracranial Bolt is indicated for use as a component of an intracranial pressure (ICP) monitoring system designed to achieve direct ICP monitoring. Specifically, the CODMAN® Intracranial Bolt is intended to secure an ICP transducer during direct ICP monitoring in both subdural and intraparenchymal applications.

### Physical Description__________________________________________________________________________________________________________________________________________________________

The CODMAN® Intracranial Bolt is composed of the following six components: (1) bolt, (2) wing nut, (3) compression cap, (4) compression grommet, (5) washer, and (6) obturator/dura pierce (packaged with bolt assembly). The bolt component is screwed into the cranium in order to secure the transducer. This is achieved through compression of the grommet via tightening of the compression cap. Additionally, a wing nut is provided as a component of the assembly as a means of bolt insertion, and a washer is provided if thread depth variation is desired. Finally, an obturator/dura pierce is provided to clear the inner lumen of the bolt and pierce the dura prior to transducer insertion. All patient contacting components are constructed of fully biocompatible implant materials.

Dear Mr. Flaherty:

We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the---current Good Manufacturing Practice requirements , as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic (QS) inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for
