Mayfield® Radiolucent Skull Clamp
Not Found
No
The description focuses on the mechanical aspects of a skull clamp for rigid fixation during surgery and imaging, with no mention of AI or ML capabilities.
No
The device is a skull clamp used for rigid fixation during surgery and imaging, not for treating a disease or condition.
No
The device is a skull clamp used for rigid fixation during surgery and imaging procedures. It physically secures the head and neck, but does not perform diagnostic functions like analyzing images or providing test results.
No
The device description clearly describes a physical skull clamp, which is a hardware component, not software.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are devices used to examine specimens taken from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening.
- Device Function: The Mayfield MR/CT Skull Clamp is a surgical instrument used to physically hold a patient's head and neck in a fixed position during surgical procedures and imaging. It does not analyze any biological specimens.
- Intended Use: The intended use clearly describes a physical fixation device for surgical and imaging procedures, not a diagnostic test performed on samples.
Therefore, based on the provided information, the Mayfield MR/CT Skull Clamp is a surgical and positioning device, not an In Vitro Diagnostic.
N/A
Intended Use / Indications for Use
The Mayfield® MR/CT Skull Clamp is placed on the patient's skull to hold their head and neck securely in a particular position when rigid fixation is desired. The clamp is indicated for us in open and percutaneous craniotomies as well as spinal surgery when rigid fixation is necessary. In addition, the clamp is indicated for use during utilization of imaging modalities such as intraoperative CT and MR imaging, C-Arm x-ray, and digital subtraction techniques.

Device Description
The Mayfield® MR/CT Skull Clamp is designed to provide rigid skeletal fixation for proccdures involving all imaging modalities, intra-operative MR, CT and digital subtraction angiography. The Skull Clamp is designed for patient positioning in the prone or supine positions. The design of the Skull Clamp allows the surgeon more freedom in positioning the fixation pins. Avoidance of critical areas of the skull is made possible by a swiveling rocker arm which rotates 360°. In addition, the swiveling rocker arm can rotate 360° under full skeletal force, making final positioning after pin impingement easier. The lean body design of the Mayfield® MR/CT Skull Clamp also allows for greater exposure to the operative site.

Substantial Equivalence:
The Mayfield® MR/CT Skull Clamp is substantially equivalent to the Mayfield® Radiolucent Skull Clamp,
Indications Use:
The Mayfield® MR/CT Skull Clamp is placed on the patient's skull to hold their head and neck securely in a particular position when rigid fixation is desired. The clamp is indicated for us in open and percutaneous craniotomies as well as spinal surgery when rigid fixation is necessary. In addition, the clamp is indicated for use during utilization of imaging modalities such as intraoperative CT and MR imaging, C-Arm x-ray, and digital subtraction techniques.

Conclusion:
The Mayficld® MR/CT Skull Clamp is substantially equivalent to the commercially marketed predicate device and does not raise new issues of safety and effectiveness.
