Corbett W. Stone - San Diego CA, US
Robin H. Vaughn - Escondido CA, US
Jeffrey H. Owens - Monkton MD, US

Assignee:

NuVasive, Inc. - San Diego CA

International Classification:

A61B 5/04
A61B 5/05

US Classification:

600554, 600546

Abstract:

An electromyography system and related method for performing automated screw test procedures, involving automatically determining an onset neuro-muscular response to the application of an electrical stimulus to a portion of pediculur bone and communicating to a user an onset electrical stimulus level which causes the onset neuro-muscular response.

International Classification:

A61B 5/05

US Classification:

600547

Abstract:

Systems 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. A stimulator is configured to generate an electrical stimulus to be applied to the first aspect of the bone. A monitor is configured to electrically monitor 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. An adjuster is configured to automatically increase the magnitude of the electrical stimulus to until the onset neuro-muscular response is detected. Lastly, a communicator is configured to communicate 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.

US Classification:

607099000, 606032000, 607117000

Abstract:

A method of determining relative neuro-muscular response onset value thresholds for a plurality of spinal nerves, comprising: depolarizing a portion of the patient's cauda equina; and measuring the current intensity level at which a neuro-muscular response to the depolarization of the cauda equina is detected in each of the plurality of spinal nerves. A method for detecting the presence of a nerve adjacent the distal end of at least one probe, comprising: determining relative neuro-muscular response onset values for a plurality of spinal nerves; emitting a stimulus pulse from a probe or surgical tool; detecting neuro-muscular responses to the stimulus pulse in each of the plurality of spinal nerves; and concluding that the electrode disposed on the distal end of the at least one probe is positioned adjacent to a first spinal nerve when the neuro-muscular response detected in the first spinal nerve is detected as a current intensity level less than or equal to a corresponding neuro-muscular response onset value of the first spinal nerve.
