AtlasPlan is intended to be used for pre- and intra-operative planning of stereotactic procedures. This software module correlates a patient's anatomy (obtained from CT or MRI scans) with an anatomical atlas of the brain. AtlasPlan may be used alone or in conjunction with neurosurgery, radiotherapy, and radiosurgery planning systems.

Device Description

AtlasPlan is a stereotactic planning tool which gives the clinician access to a digitized atlas of the brain. The AtlasPlan system, addressed in this premarket notification, has the same intended use and technological characteristics as the commercially available MIDCO cass System. Like the cass System, AtlasPlan utilizes a workstation to compare patient scans (CT or MRI) with a digitized stereotactic atlas. In addition, both systems allow the user to view entry and target points and labels for anatomical structures. Both systems output BRW coordinates for use in further procedure planning.

AI/ML Overview

The provided text does not contain detailed acceptance criteria and the results of a specific study to prove the device meets those criteria. Instead, it offers a general summary of safety and effectiveness, stating that "The RSA AtlasPlan system/unit testing rigorously tests the features of the software. The results of the testing indicate that AtlasPlan is safe and reliable for its intended use."

Therefore, I cannot populate the table or provide specific details for points 1-9 as the necessary information is not present in the given document.

Missing Information:

Specific Acceptance Criteria: The document does not list any quantitative or qualitative metrics that AtlasPlan was required to meet for acceptance.
Specific Study Details: There is no description of a particular study (e.g., a clinical trial, a performance validation study) that was conducted to demonstrate safety and effectiveness.
Device Performance Metrics: No reported performance metrics (e.g., accuracy, precision, sensitivity, specificity) for the device are provided.
Sample Size, Ground Truth Details, Expert Qualifications, Adjudication, MRMC studies, Standalone performance, Training set details: All these critical elements for evaluating a device's performance study are absent.

The 510(k) summary focuses on the substantial equivalence to a predicate device (MIDCO cass System) and general statements about testing, user manuals, and training to ensure safe and effective use. It does not include the detailed performance study information requested.

Dear Ms. Riek:

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 enolosure) 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 The general controls provisions of the Act 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 requirement, 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 devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.
