  • Patent number: 7925328
    Abstract: A stereotactic navigation system for navigating an instrument to a target within a patient may include a stereotactic head frame, an imaging device, a tracking device, a controller and a display. The stereotactic head frame is coupled to the patient and is used to assist in guiding the instrument to the target. The imaging device captures image data of the patient and of the stereotactic head frame. The tracking device is used to track the position of the instrument relative to the stereotactic head frame. The controller receives the image data from the imaging device and identifies the stereotactic head frame in the image data and automatically registers the image data with navigable patient space upon identifying the stereotactic head frame, while the display displays the image data.

  • Publication number: 20050245806
    Abstract: In general, the invention is directed to strategies pertaining to implantation of an implantable medical device between a scalp and a skull of the patient. The invention pertains to collection of data such as data pertaining to the skull of the patient, the scalp of the patient, the vascular structure or neurological structures in the head of the patient, and the like. The data may be in the form of images, such as images generated by X-ray, magnetic resonance imaging, CT-scan and fluoroscopy. A surgeon can use the collected data to determine, for example, whether the patient is a candidate for a cranial implantation, whether the patient's skull and scalp can support the implantation, what configuration of device should be implanted, where the device should be implanted, and how the surgical incisions should be made.
