Patent number: 11129643Abstract: A neurosurgical apparatus includes a guide device and a neurosurgical instrument is disclosed. The guide device includes a tube for insertion into the brain and a head attached to the proximal end of the tube for affixing the guide device to a hole formed in the skull. The head has a passageway therethrough in communication with the bore of the tube such that the bore of the tube and the passageway through the head define an internal channel through which a neurosurgical instrument can be passed into the brain of the subject. The neurosurgical instrument is for insertion to a desired brain target through the internal channel of the guide device. The apparatus includes one or more sealing elements for providing a fluid tight seal between the internal channel of the guide device and the exterior of the neurosurgical instrument to prevent fluid leakage from guide tube.Type: GrantFiled: February 27, 2013Date of Patent: September 28, 2021Assignee: RENISHAW PLCInventors: Steven S Gill, Attila Antalfy

Patent number: 9802028Abstract: A cerebral catheter device for draining fluid from the brain of a patient is described. The device may be used as part of a ventricular shunt system. The device includes an elongate tube for insertion into the brain of a patient to a vicinity of a desired target. A head is attached to the elongate tube that has a passageway in fluid communication with a lumen of the elongate tube. Formations are provided on the external surface of the head for securing the head in a hole formed in the skull of a patient. The head further includes a first fluid connector portion that is attachable to an associated drainage catheter device. This allows fluid communication to be established between the lumen of the elongate tube and a drainage catheter device via the passageway of the head.Type: GrantFiled: October 4, 2012Date of Patent: October 31, 2017Assignee: RENISHAW (IRELAND) LIMITEDInventor: Steven S Gill

Patent number: 8554325Abstract: A movement state of a patient is detected based on brain signals, such as an electroencephalogram (EEG) signal. In some examples, a brain signal within a dorsal-lateral prefrontal cortex of a brain of the patient indicative of prospective movement of the patient may be sensed in order to detect the movement state. The movement state may include the brain state that indicates the patient is intending on initiating movement, initiating movement, attempting to initiate movement or is actually moving. In some examples, upon detecting the movement state, a movement disorder therapy is delivered to the patient. In some examples, the therapy delivery is deactivated upon detecting the patient is no longer in a movement state or that the patient has successfully initiated movement. In addition, in some examples, the movement state detected based on the brain signals may be confirmed based on a signal from a motion sensor.Type: GrantFiled: January 6, 2012Date of Patent: October 8, 2013Assignee: Medtronic, Inc.Inventors: Gregory F. Molnar, Steven S. Gill, Keith A. Miesel, Mark S. Lent, Timothy J. Denison, Eric J. Panken, Carl D. Wahlstrand, Jonathan C. Werder

Patent number: 8206399Abstract: An intervertebral joint prosthesis having a ball component (22) for engagement with a first vertebra (26) and a trough component (24) for engagement with a second vertebra (27) adjacent to the first vertebra is disclosed. The trough component (24) includes a generally concave surface (50) having a substantially flat portion (52). When the ball component (22) and the trough component (24) are engaged to their respective vertebrae, the ball component (72) and the trough component (24) engage each other, permitting rotation and translation of the vertebrae with respect to each other. Both components include a flange (34,56) for engaging a vertebra. The invention also contemplates a method for and a tool for use in implanting a two-piece intervertebral joint prosthesis.Type: GrantFiled: April 1, 2003Date of Patent: June 26, 2012Assignee: Warsaw Orthopedic, Inc.Inventors: Steven S.
