•
Use the wrench to support the anchor while twisting the driver counterclockwise out of the anchor.
•
Inspect the attachment of the anchor to the skull. Anchors must be tight. Replace stripped anchors in a new location.
Note that if anchors are not fully seated in the skull, they should be tightened by hand with the hex wrench.
•
Close each anchor wound over the anchor.
•
Repeat this process for all remaining anchors.
4. Scan the patient (see next section).
5. Once scans have been checked to ensure that all anchors are displayed properly, patient may be released.
Scanning
WayPoint™ Anchors are CT visible. The patient’s head must be kept immobile while being scanned.
CT Scan requirements:
• Contiguous slices; no gaps between slices
• No overlapping slices
• Slice thickness no greater than 1.25mm
• Pixel size less than 1mm (0.5 to 0.8mm for best results)
• Gantry tilt angle of zero
Non-clinical testing demonstrated that the WayPoint™ Anchors are MR Conditional. A patient with this device can be scanned
safely, immediately after placement under the following conditions:
MR Scan requirements:
• Static magnetic field of 3-Tesla or less
• Maximum spatial gradient magnetic field of 720-Gauss/cm or less
• Refer to WayPoint™ Anchor/Locator Implantation Kit DFU (L011-40) for detailed MRI safety information on the WayPoint™
Anchors
MR image quality may be compromised if the area of interest is in the exact same area or relatively close to the position of the
WayPoint™ Anchor. Therefore, optimization of MR imaging parameters to compensate for the presence of this device may be
necessary.
