A cranial lead fixation device includes a body configured for fixation to a cranium over or within a burr hole, and a fixation mechanism associated with the body. The body and fixation mechanism capture a medical device (e.g., a lead, catheter, or similar device) within a fixation channel of the cranial lead fixation device for protection of the burr hole and securement of the medical device. The cranial lead fixation device is operable for a first open configuration and a second closed configuration.

A system for MRI-guiding of a cranial drill for drilling a burr hole into a skull of a patient in vivo. The system comprises an MRl-compatible controller configured to send actuator commands and an MRI-compatible cranial drill system adapted to be secured to, or proximate to, the head of the patient. The cranial drill system includes a pressure sensor and is adapted to receive the actuator commands and send position data and force feedback from the pressure sensor to the controller. A fiber optic cable is connected between the controller and navigation software. The navigation software is configured for transmitting scanner control signals to the MRI scanner and receiving images generated by the MRI scanner for transmission to a display output for receiving electrical signals and for displaying corresponding images. The navigation software is adapted to receive commands based on the images.

An implantable cranial medical device (100) includes a first fluid flow path, a second fluid flow path, and upper flange portion (110), and a lower portion (120). The upper flange portion (110) is configured to rest on a skull of a subject about a burr hole. The lower portion (120) is configured to be placed within the burr hole. The first fluid flow path may extend from a first opening (150) in the upper flange portion (110) to a first opening (132) in the lower portion (120). The second fluid flow path may extend from a second opening (140) in the upper flange portion (110) to a second opening (134) in the lower portion (120).

A targeting guide is disclosed includes a handle extending substantially along a longitudinal axis. The longitudinal handle defines one or more burr holes extending from a first side of the handle to a second side of the handle. A head is coupled to a distal end of the longitudinal handle. The head defines a plurality of guide holes sized and configured to receive a k-wire therethrough.

A medical device for accessing soft tissue of the brain may include a delivery sleeve assembly including a sheath configured to receive a surgical access device and mate with a socket arrangement of a cranial burr hole device arranged on a patient, and a depth stop arranged on the sheath of the delivery sleeve assembly configured to be selectively adjusted along the sheath to an incremental depth marker associated with the location of a surgical site.

A burr hole device is configured to receive a catheter and a cable of a sheath. The sheath is configured to receive a portion of the catheter and has an electrode. When the catheter and sheath are implanted with the burr hole device, the catheter and electrode of the sheath are implanted in a brain. Systems and apparatuses may include the burr hole device and / or a cranial port device, the catheter, and the sheath.

Various embodiments of a catheter stabilizer that includes a retention body and an occluder for positioning within a burr hole or other channel in the body for occlusion and stabilization of a catheter during a surgical procedure are described herein. Specifically, the retention body further defines a channel configured to be oriented above the burr hole; in some embodiments the channel can provide reference for drilling a burr hole after placement of the retention body. The catheter stabilizer further includes an occluding arm, which can be positioned across an opening of the burr hole for receiving and occluding a catheter within the burr hole.
