A lead fixation accessory configured to be positioned over a skull hole and to transition between an opened state and a closed state during a lead implant procedure protects against lead migration by providing a mechanism for securing the lead in place at the skull hole while a stylet is removed from the lead. The lead fixation accessory remains in place after the implant procedure to provide chronic lead stability. A lead stabilization tool configured to access and grip a lead through a slotted cannula during the lead implant procedure also protects against lead migration by providing a mechanism for securing the lead in place at a point where the lead exits the skull hole while the slotted cannula is removed from the skull hole and peeled away from the lead.

An artificial bone plate unit and an assembleable artificial bone plate are provided. The artificial bone plate unit includes a plate body, multiple connecting pins, connecting holes, drug cavities, and drug-releasing openings. The plate body has two main surfaces and a peripheral surface connected between the two main surfaces. The connecting pins and the connecting holes are formed on the plate body and arranged along the peripheral surface on the plate body. The connecting holes correspond in shape to the connecting pins. The drug cavities are formed in the artificial bone plate unit and are connected to the drug-releasing openings. The artificial bone plate units are connected using the connecting pins and the connecting holes to form the assembleable artificial bone plate. The assembleable artificial bone plate can be bent into the shape of a defect area of the skull, which saves material and time.

A fixation device includes a body having a first axial end and a second axial end defining a longitudinal axis. The body has a longitudinal bore therein, and a longitudinal slot in a first side of the body extending laterally to the bore. A mounting bracket is connected to the first axial end at a second side opposite the slot and extends outward therefrom. The mounting bracket is configured to be mounted to a first structure. A support member is retained in the bore and is configured to move longitudinally in the bore. The support member protrudes outward from the first side of the body to support a second structure a longitudinal distance from the first structure. A lead screw engages a threaded hole in the base whereby rotation of the lead screw moves the support member to adjust the longitudinal distance between the first and second structures.

An adjustable cranioplasty plate assembly is provided for use following a craniectomy. The assembly includes a ring which is attached to the skull around the skull opening and a plate adjustably mounted to the ring. The plate is moveable between a raised position spaced above the ring and a lower position substantially flush with the ring. The plurality of extendable and retractable struts extends between the ring and the plate to provide the plate adjustability. The plurality of stay cables extending between the ring and the plate provide lateral stability in the raised position. The assembly replaces the native bone and eliminates the need for subsequent cranioplasty surgery. In one embodiment, the plate includes a rigid central portion, three rigid mounting tabs, and a plurality of malleable tapered perimeter petals which provide a smooth interface between the plate and the skull of the patient.

An osteotomy gap filling implants and related methods. In one example, the implant may include several implant segments, at least some of which include a porous body, in combination with a non-porous flexible spine extending through the implant segments.

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.

A ventricular catheter assembly including a proximal catheter and a cooperating cranial cover. The cranial cover includes a base plate having an opening aligned with a burr hole in the skull of a person. A guide extends upwardly from the base plate and receives the proximal catheter.
