The ClearPoint System is intended to provide stereotactic guidance for the placement and operation of instruments or devices during planning and operation of neurological procedures within the MRI environment and in conjunction with MR imaging. The ClearPoint System is intended as an integral part of procedures that have traditionally used stereotactic methodology. These procedures include biopsies, catheter and electrode insertion. The System is intended for use only with 1.5 and 3.0 Tesla MRI scanners.

The hardware and software components of the SurgiVision ClearPoint System. The hardware and software components of the SurgiVision ClearPoint System 37 are identical to the predicate device. The sole purpose of this 510(k) application is to expand the indications for the ClearPoint System to 3.0 Tesla MRI scanners. The ClearPoint System 3T is intended to provide trajectory planning, guidance and fixation of neurosurgical tools during minimally invasive stereotactic surgical procedures in the brain conducted in the MR suite. The System itself provides no therapeutic or diagnostic functionality. The ClearPoint Stereotactic System is comprised of two separate device groups, a hardware and a software group. The software group is known as the ClearPoint Workstation. It includes the following: ClearPoint Workstation Software (for trajectory planning and . monitoring) Laptop Computer . The hardware device group under the ClearPoint Stereotactic System umbrella is known as the SmartFrame and Accessories.

The Intercept™ Internal MR Coils are recommended for high-resolution Magnetic Resonance Imaging of internal anatomical structures.
