It has been discovered that pain felt in a given region of the body can be treated, not by motor point stimulation of muscle in the local region where pain is felt, but by stimulating muscle spaced from a “nerve of passage” in a region that is superior (i.e., cranial or upstream toward the spinal column) to the region where pain is felt. Spinal nerves such as the intercostal nerves or nerves passing through a nerve plexus, which comprise trunks that divide by divisions and/or cords into branches, comprise “nerves of passage.”

Described herein is a cranial surgery drill bit having a safety self stopping mechanism for use on bone material to prevent or repair skin erosion and infection which may result from the placement of a cap for holding the lead from Deep Brain Stimulation surgery. The surgical procedure of attaching a lead holding cap onto the bone material of a skull requires an attachment which results in no movement of the lead. Accordingly, counter boring the skull surrounding a pre-existing perforation bore so that the cap is not significantly above the surface of the skull is a technique which allows the cap user to brush hair, etc., without disrupting the attachment and placement of the lead.

A cranial fixation system and method are provided. The system includes two heads slidably connected with telescopic extensions and a spring or an elastomeric flexible component. The two heads are maintained in a distracted position by a locking mechanism until ready for cranial implantation. Once implanted, the locking mechanism is disengaged, thereby allowing the heads to compress towards each other by the spring and approximate the cranial bone flap to the skull.

The invention relates to the field of ultrasonic detection, in particular to an automatic detection and display method for an ultrasonic craniocerebral abnormal area. According to the technical scheme, firstly, a skull curved surface model is constructed, then edge detection is conducted on a 2D ultrasonic image to obtain a skull edge curve, and the edge curve and the skull curved surface model are used for fitting to determine the position of the 2D ultrasonic image so as to judge whether the 2D image has the symmetry characteristic or not; and finally, carrying out similarity comparison calculation on the two symmetrical regions by utilizing the symmetry characteristic of the 2D image so as to determine whether an abnormal region exists and determine the position of the abnormal region. The method has the advantages that the skull curved surface model is firstly established, the skull boundary curve of the 2D ultrasonic image is detected, the skull boundary curve and the skull curved surface model are fitted to determine the specific position of the 2D image so as to select the 2D image with the symmetry characteristic, and the abnormal area is detected, segmented and displayed by using the symmetry of the 2D image. Therefore, the accuracy of abnormal region detection is effectively improved.

A cranial remodeling orthotic for passive remodeling of a cranium of an infant has (i) a main frame assembly for encircling the infant cranium (ii) at least one support member having a concave inner surface to extend circumferentially with the main frame assembly about a portion of the infant cranium while protruding beyond at least one of the upper boundary or the lower boundary of the main frame assembly, and (iii) a resilient cushion layer lining an inner surface of a portion of the main frame assembly or the support member. The support member is rigid and self-supporting, while being formable in shape upon the application of heat more readily than the main frame assembly. The resulting orthotic can be mass produced while still allowing some customization for the end user so as to effectively treat headshape asymmetry without the need for 3D scans or plaster casting.

A system for non-invasively measuring blood volume oscillations inside a cranium of a human subject. The system includes a first light source adapted to be placed on the skin above the cranium of the human subject configured to emit light which penetrates a superficial space outside the cranium. A detector is adapted to be placed on the skin above the cranium of the human subject spaced from the first light source by a first predetermined separation distance that causes the detector to detect light which reflects from the superficial space outside the cranium and output superficial output signals. A second light source is adapted be placed on the skin above the cranium configured to emit light which penetrates through the superficial space outside the cranium to inside the cranium and the detector is spaced from the second light source by a second predetermined separation distance that causes the detector to detect light which reflects from inside the cranium and output cranial output signals. A processing subsystem is coupled to the first light source, the second light source, and the detector. The processing subsystem is configured to alternately enable the first light source and the second light source and alternately enable the detector to detect the light which reflects from the superficial space outside the cranium and the light which reflects from inside the cranium to generate the superficial output signals and cranial output signals. The processing subsystem is responsive to the superficial output signals and the cranial output signals and is further configured to reduce contributions from the superficial space existing in the cranial output signals and generate corrected cranial output signals indicative of blood volume oscillations inside the cranium. The system and method to measure blood volume oscillations inside the cranium of a human subject may use the measured blood volume oscillation to non-invasively measure ICP.
