The IMRIS Head Fixation Device System is an MR compatible mechanical support system which is used in head, neck and spine surgery when rigid fixation is required for cranial stabilization.
Device Description
The IMRIS Head Fixation Device System (HFD100) Rocker Arm Accessory is an MR compatible mechanical support system intended to use in head, neck and spine surgery when rigid fixation is required for cranial stabilization. The HFD100 and its accessories are designed to immobilize the head during surgical procedures and support patient in the prone, supine or lateral positions. The HFD100 system is comprised of the table adapter, linkage system, one or two rocker arm skull clamps, and skull pins. The HFD100 system can be used with either the operating room table or the angiography room table. The table adaptor is used to mount HFD100 on the table. The linkage system is used to mount the Skull Clamp (including 3 or 4 skull pins) to the table Adapter. The Skull Clamp requires the use of three (3) or four (4) Skull Pins. IMRIS is using MAYFIELD® Disposable and Reusable Titanium Skull Pins manufactured by Integra LifeSciences Corporation and cleared by FDA K072208. The MAYFIELD® Disposable and Reusable Titanium Skull Pins are used in surgical procedures when rigid fixation is desired and Intra-Operative MR imaging is used. IMRIS 3-pin and 4-pin HFD100 attached to the OR table assembly is part of the IMRISneuro system. The linkage system is used to position the skull clamp in the necessary position, without colliding with the magnet bore. The HFD100 can be used individually or with the IMRIS Flexible Intra-operative Head Coils and third party accessories, such as retractor systems and navigation mounts. The HFD100 provides rigid skeletal fixation within the optimal imaging envelope while introducing minimal artifacts in the acquired images. The IMRISneuro 1.5T/3T Systems (Neuro III-SV) are traditional MRI units that have been suspended on an overhead rail system to facilitate intra-operative, interventional and diagnostic use. The main components of the IMRISneuro systems are the MRI system, the magnet mover system, the OR Table assembly, the Intra-operative Coil and the Head Fixation Device. The IMRISneuro intraoperative imaging systems are tools for radiologists and surgeons, used to acquire images for diagnosis and surgical planning and monitoring during surgery. When images are requested by the surgeon, the magnet is brought into the operating room or Angiography room moving on a pair of overhead rails. The patient remains stationary throughout the procedure and the magnet moves into the room and over the patient for imaging. The magnet can be moved into and out of the surgical field multiple times, as required, throughout the course of the surgical procedure. The surgeon has access to updated MR images in the surgical field, but does not have to change the surgery would typically be performed. Obtaining images intra-operatively allows surgeons to verify the absence of surgical complications before releasing the patient from the operating room.
More Information

No
The device description focuses on a mechanical support system for head fixation during surgery and does not mention any software, algorithms, or data processing that would indicate the use of AI/ML.

No

Explanation: The device is a mechanical support system designed to immobilize the head during surgery for cranial stabilization and to facilitate intra-operative imaging. It does not directly treat a disease or condition.

No

This device is a mechanical support system used for rigid fixation and immobilization of the head during surgical procedures. It enables intra-operative imaging but is not itself a diagnostic device; rather, it is a tool for surgery support.

No

The device description clearly outlines a mechanical support system comprised of physical components like a table adapter, linkage system, rocker arm skull clamps, and skull pins. It is a hardware device for rigid fixation.

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

Here's why:

  • Intended Use: The intended use is clearly stated as a "mechanical support system which is used in head, neck and spine surgery when rigid fixation is required for cranial stabilization." This describes a surgical tool for physical support and immobilization.
  • Device Description: The description details a system of mechanical components (table adapter, linkage system, skull clamps, skull pins) designed to "immobilize the head during surgical procedures." This reinforces its function as a physical support device.
  • Lack of Biological Sample Analysis: IVD devices are designed to examine specimens derived from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening. This device does not interact with or analyze any biological samples.
  • Role in the IMRISneuro System: While the device is used in conjunction with an MRI system for intra-operative imaging, its role is to provide stable positioning for the patient during imaging and surgery, not to perform the diagnostic analysis itself. The MRI system is the diagnostic tool in this context.

In summary, the IMRIS Head Fixation Device System is a surgical accessory used for patient positioning and stabilization during procedures, not a device that performs in vitro diagnostic testing on biological samples.

The Skull Clamp requires the use of three (3) or four (4) Skull Pins. IMRIS is using MAYFIELD® Disposable and Reusable Titanium Skull Pins manufactured by Integra LifeSciences Corporation and cleared by FDA K072208. The MAYFIELD® Disposable and Reusable Titanium Skull Pins are used in surgical procedures when rigid fixation is desired and Intra-Operative MR imaging is used. IMRIS and Integra LifeSciences Corporation have signed a supplier agreement to allow use of their titanium pins as a component of the IMRIS HFD100 system. Integra is responsible for the regulatory approvals of this product.

IMRIS 3-pin and 4-pin HFD100 attached to the OR table assembly is part of the IMRISneuro system. The linkage system is used to position the skull clamp in the necessary position, without colliding with the magnet bore. The HFD100 can be used individually or with the IMRIS Flexible Intra-operative Head Coils and third party accessories, such as retractor systems and navigation mounts. The HFD100 provides rigid skeletal fixation within the optimal imaging envelope while introducing minimal artifacts in the acquired images.

images in the surgical field, but does not have to change the surgery would typically be performed. Obtaining images intra-operatively allows surgeons to verify the absence of surgical complications before releasing the patient from the operating room. IMRIS 1.5T (Neuro II-SE) is cleared by K061916 and K071099 and IMRIS 3T (Neuro III-SV) is cleared by K093137 and K091166.

Intended Use:

The IMRIS Head Fixation Device Rocker Arm Accessory is an MR compatible mechanical support system which is used in head, neck and spine surgery when rigid fixation is required for cranial stabilization.

Comparison with Predicate Devices:

The IMRIS Head Fixation Device (HFD100) Rocker Arm Accessory is substantially equivalent to the currently cleared and marketed IMRIS HFD100 (K103493). The only design change to the current HFD100 is the addition of the Rocker Arm Accessory allowing the physician to choose between a 3-pin configuration and a 4-pin configuration.

The current HFD100 is an MR compatible mechanical support system which is used in head, neck and spine surgery when rigid fixation is required for cranial stabilization. It uses one rocker arm with 2 pins and stationary pin holder on the opposite side. The HFD100 Rocker Arm Accessory is also an MR compatible mechanical support system which is used in head, neck and spine surgery when rigid fixation is required for cranial stabilization, however, it allows the physician to choose the current 3-pin configuration of the HFD100 or they have the option to switch out the stationary pin holder for the Rocker Arm Accessory adding an additional pin to the configuration; distributing the weight evenly over all 4 pins. These differences have been identified and assessed in risk management and verification and validation testing.

Standards:

No product standards have been referenced within this submission.

Image /page/7/Picture/0 description: The image shows the logo for IMRIS. The logo consists of the word "IMRIS" in bold, black letters, followed by a blue circle with two horizontal lines inside. The circle is slightly broken, giving it a modern and technological feel. The overall design is clean and professional.

Summary of Studies:

HFD100 Rocker Arm Accessory performance has been evaluated in verification and validation to ensure the 4-pin configuration maintains the performance of the 3-pin HFD100 system components.

HFD100 Rocker Arm Accessory verification and validation supports a determination of substantial equivalence.

Conclusion:

The IMRIS Head Fixation Device (HFD100) with the Rocker Arm Accessory is substantially equivalent to the currently cleared and marketed IMRIS HFD100 (K103493).
