Publication number: 20080064976Abstract: Methods for determining structural integrity of a bone within the spine of a patient, the bone having a first aspect and a second aspect, wherein the second aspect separated from the first aspect by a width and located adjacent to a spinal nerve. The methods involve (a) applying an electrical stimulus to the first aspect of the bone; (b) electrically monitoring a muscle myotome associated with the spinal nerve to detect if an onset neuro-muscular response occurs in response to the application of the electrical stimulus to the first aspect of the bone; (c) automatically increasing the magnitude of the electrical stimulus to until the onset neuro-muscular response is detected; and (d) communicating to a user via at least one of visual and audible means information representing the magnitude of the electrical stimulus which caused the onset neuro-muscular response.Type: ApplicationFiled: October 31, 2007Publication date: March 13, 2008Applicant: NuVasive, Inc.Inventors: Brian Kelleher, James Marino, Corbett Stone, Robin Vaughn, Jeffrey Owens

Publication number: 20070078435Abstract: An injection apparatus that includes components that facilitate injection of relatively viscous materials into a subject is provided as well as methods of use. An injection apparatus may include a transition-bore needle apparatus, which has a proximal end, a distal end, and a lumen extending from the proximal end to the distal end, in which the diameter of the proximal end is greater than the diameter of the distal end. An injection apparatus may include a hand-held injection facilitation apparatus, which may be coupled to a syringe. The hand-held injection facilitation apparatus can include a pivot arm and a body with a rod disposed within the body and coupled to the pivot arm. Movement of the pivot arm results in a proximal or distal movement of the rod within the body to effectively cause material to be expelled from the syringe. An injection apparatus may include a transition-bore needle apparatus and a hand-held injection facilitation apparatus in combination.Type: ApplicationFiled: June 16, 2006Publication date: April 5, 2007Inventors: Corbett Stone, Russell Anderson

Publication number: 20070073342Abstract: Suture locking devices and methods. In one embodiment, the device includes a suture lock, a rotatable actuator adjacent to the lock, and a release mechanism. The lock defines a pair of suture holes which receive sutures attached to tissue (e.g. a spinal disc) of the surgical site. When the actuator rotates the sutures are wound together (preferably around a hub on the lock) thereby securing the plate to the tissue. Furthermore, the release mechanism is coupled to the lock in such a manner that when the release mechanism is actuated the device releases the lock. The release mechanism may include a push button that is biased away from the lock. Also, the actuator may include a thumbwheel and a gear. Further, the gear may also define suture holes. Additionally, a pull ring connected to a pair of loops for drawing the sutures through the instrument may be included.Type: ApplicationFiled: September 26, 2006Publication date: March 29, 2007Inventors: Corbett Stone, Jennifer Diederich, Bryan Knodel
