No
The device description explicitly states that it has "no software or electrical components" and the summary does not mention any AI/ML related terms or functionalities.
No
This device is designed to provide access and visualization during neurological cranial surgery, acting as a surgical tool rather than delivering any therapeutic effect itself.
No
The device description clearly states its purpose is to provide access, allow visualization, and retract soft tissue during surgery. It is a surgical tool, not a diagnostic one.
No
The device description explicitly states that the MindsEye device is made of biocompatible, medical grade materials (metals and polymers) with no software or electrical components.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states that the device is for providing access, visualization, and retraction during neurological cranial surgery. This is a surgical tool used in vivo (within the living body) to facilitate a surgical procedure.
- Device Description: The description reinforces its function as a surgical access and retraction device. It describes its physical components and how it is used during surgery.
- Lack of IVD Characteristics: An IVD device is used to examine specimens derived from the human body (like blood, urine, tissue) in vitro (outside the body) to provide information for diagnosis, monitoring, or screening. This device does not perform any such function. It is a surgical instrument.
Therefore, the MindsEye Expandable Port is a surgical device, not an In Vitro Diagnostic device.

Device Description
The MindsEye Expandable Port is a single use, minimally invasive intracranial medical device designed to provide access and allow visualization to the surgical field while retracting subcortical soft tissues during neurological cranial surgery. Its design allows the user to place the port while collapsed in its minimal form for atraumatic access to the subcortical space. After placement, the port can be expanded radially to create a working channel to the target surgical location. The user is able to expand the port to the desired working channel diameter appropriate for the surgical plan then collapse the port upon surgical completion for safe removal. The working channel diameter may be adjusted as needed by the user throughout surgery.
The MindsEye device is expected to be used in conjunction with other standard, commercially available intracranial medical devices, such as an aspirator, micro/endo/exoscope, irrigation, electrosurgical systems/tools and/or hemostatic agents. In addition, MindsEye is compatible with existing optical navigation systems for accurate target acquisition and may be attached to other commercial retraction systems according to user preference.
The MindsEye device is made of biocompatible, medical grade materials (metals and polymers) with no software or electrical components. The MindsEye device and its components are provided sterile and not reusable.
MindsEye is comprised of the following components and is available in three lengths (Table 1).

TECHNOLOGICAL CHARACTERISTICS COMPARISON 5.6
While there are expected technological differences due to the ability of MindsEve to be placed in collapsed form then expanded (dilatable working channel) as compared to the static size working channel offered by the predicate; the overall indication for use, principles of operation and placement as well as general size of the device are similar to the predicate and reference devices.
Similar Characteristics:
Like the predicate and reference devices, the MindsEye port is placed using an obturator for atraumatic introduction. Placement can be performed using a commercial optical navigation system often utilized for surgical planning. The obturator is then removed leaving a working channel to allow for visualization and surgical access within the brain tissue. MindsEye can accommodate a minimum inner diameter (i.e. working channel) of 6mm to a maximum diameter of 21mm. The inner diameter range of MindsEye (6 - 21mm) is smaller then or within the diameter range of the predicate and references devices (11 – 28mm). Similarly, MindsEye is available in three port lengths (52 – 77mm) to accommodate various surgical locations which is also within the length range of the predicate and references devices (30 - 95mm). The transparent sheath allows users to see cerebral vasculature, structures and tissue adjacent to the sheath and accommodates the visualization preferences (i.e. use of an endoscope, microscope, loupes, etc.) of the user during surgery. Finally, MindsEye is compatible with typical adjunct surgical instruments such as larger retraction systems, aspirators, forceps, bipolar and other electrosurgical and hemostasis devices.
Different Characteristics:
To allow for the radial dilation of the MindsEye port, it was designed with a flexible, compliant sheath and controlled mechanism to expand and contract as intended. This is the primary difference from the predicate and reference devices which have a hard, static size sheath. To achieve this, different materials of manufacture are used as compared to the predicate and reference devices, however comprehensive biocompatibility testing was performed to maintain the safety profile of the device. Characterization and performance testing were completed to provide assurance that the sheath of the MindsEye device is robust enough to withstand the normal conditions of brain surgery. A summary of the predicate and reference device comparison is provided in Table 2.

5.8 CONCLUSION
A review of the risk assessment, biocompatibility and other non-clinical testing, in addition to demonstrated compliance with recognized standards, have established that the MindsEye Expandable Port does not raise different questions of safety or effectiveness for the described intended use when compared to the predicate and reference devices. Therefore, the results of these analyses provide reasonable assurance that the MindsEye Expandable Port has a similar safety and effectiveness profile as compared to the predicate and supports a determination of substantial equivalence.
