A method for performing a cranioplasty includes the steps of prefabricating a sonolucent craniofacial implant based upon information generated by preoperative scans, creating a cranial, craniofacial, and/or facial defect, and attaching the craniofacial implant to the cranial, craniofacial, and/or facial defect. The craniofacial implant is composed of a material that is sonolucent and exhibits attenuation of less than 6 dB/cm.

Apparatus for providing repeated cranial access comprises a hollow shaft sized to fit within a hole extending through a skull bone, the hollow shaft having a length of at least a thickness of the skull bone, a lip extending laterally form a first end of the hollow shaft for abutting the skull bone around the hole, and, a plug sized to fit into the hollow shaft, the plug extending at least the length of the hollow shaft and configured to be removably secured within the hollow shaft.

An intracranial prosthesis comprised of a flat body having an interior ultrasound-compatible window and a ring having a plurality of access ports about the outer portion capable of engaging a plurality of diagnostic instruments and/or intracranial delivery systems so that a practicing medical professional can monitor certain parameters of a patient or deliver therapeutic agents to the patient while using an ultrasound-monitoring device to image the patient's brain. The prosthesis is designed to allow for the continuous, uninterrupted, simultaneous monitoring of a number of parameters of a patient's brain at the patient's bedside.

Provided herein is a clip type cranial flap closing and anchoring device having a single structure including first part in contact with top surface of the flap and second part in contact with bottom surface of said flap maintaining a gap therebetween to accommodate the flap, wherein the first part is fixedly secured to third part for fastening the device to the skull.

A burr hole cover is provided that is constructed to be positioned within a recessed region formed on a patient's skull in order to conceal a burr hole. The burr hole cover may be affixed to the patient's skull in the recessed region. For instance, surgical fastening devices may be inserted through apertures defined in the burr hole cover. The burr hole cover may have a thickness and curvature that enables it to be substantially flush with the surface of the skull when affixed in the recessed region. The burr hole cover's curvature follows the contour of the patient's skull. The burr hole cover may include one or more perforations sized to allow air (or moisture) to flow towards the burr hole, which promotes skin/bone growth. Some of the perforations may be large enough to permit access to the brain with leads and/or drainage devices.

A cranial bone fastening device for temporarily fastening multiple cranial bone portions to a main body of a positioning device in order to orient the cranial bone portions relative to one another, wherein a pin-like fixing element portion is provided, one side of which is designed to contact the multiple cranial bone portions in order to secure the cranial bone portions to the main body of the positioning device upon interaction with a counter portion on the other side of the cranial bone portions.

A bone drilling cover device comprises an upper fastening member and a lower fastening member. The upper fastening member includes a first base portion and a first coupling portion. The lower fastening member includes a second base portion and a second coupling portion engagable with the first coupling portion. The second base portion is composed of at least one first arm and at least one second arm. The first arm has a length greater than a length of the second arm. A total length of the first arm and the second arm is greater than a diameter of a drilled hole. Through the first arm and the second arm having different lengths, the first arm and the second arm can be inserted in an oblique manner and positioned to the underside of the drilled hole for covering the drilled hole of any bone.

A bone drilling cover fixing device includes an upper fastening member and a lower fastening member. The upper fastening member includes a first base portion and a first coupling portion. The first coupling portion protrudes from an underside of the first base portion and can be inserted into a drilled hole. The lower fastening member includes a second base portion and a second coupling portion. The second base portion includes at least one first arm and at least one second arm. The first arm has a length equal to that of the second arm. The length of the first arm and the length of the second arm are greater than a radius of the drilled hole. When in use, the first and second arms are inserted in an oblique manner into the drilled hole to be positioned at two ends of an underside of the drilled hole.

A method for adjusting an adjustable implant includes broadcasting identification information from an adjustable implant implanted within a subject, receiving wirelessly with the adjustable implant, from a device external to the subject, an adjustment setting configured to be executed by the adjustable implant, receiving wirelessly with the adjustable implant, from a device external to the subject, an instruction to perform the adjustment setting, activating a motor on the adjustable implant to perform the adjustment setting, and sending, to a device external to the subject, a progress of the adjustment setting.

An intracranial prosthesis comprised of a flat body having an interior ultrasound-compatible window and means about the outer portion capable of engaging a plurality of diagnostic instruments and/or intracranial delivery systems so that a practicing medical professional can monitor certain parameters of a patient or deliver therapeutic agents to the patient while using an ultrasound-monitoring device to image the patient's brain. The prosthesis is designed to allow for the continuous, uninterrupted, simultaneous monitoring of a number of parameters of a patient's brain at the patient's bedside.
