Problems solved by technology

This significantly increases the risk of a second procedure-related brain injury, as well as delays in initiating device function that can pose significant risk to the patient
The need for a second or repeated procedure also results in increased costs for supplies, an excess time burden on physicians and nurses involved in patient care, and potential delays in other life-saving interventions

[0123] Example 1: Location Display

[0124] Below are representative data accumulated from a battery of tests performed on adult pigs under the auspices of the Institutional Animal Care and Use Committee protocol. Animals were anesthetized using propofol and fentanyl, and bilateral frontoparietal craniotomies were then made. The dura is opened wide to allow direct visualization of the surface of the cerebral cortex. Under direct vision, the insertion of the electrodes is performed with a trajectory perpendicular to the brain surface at the apex of the arc of the gyrus to ensure penetration down the length of the opposing gyrus. Use a diagnostic ultrasound system equipped with a convex imaging array to position the subcortical electrodes to visualize the sagittal plane to a depth of 5 cm, allowing the field of view to extend from the cerebral cortex to the brainstem. This imaging strategy allows clear distinction between the cerebral cortex, subcortical white matter, ventricl...

Abstract

Systems and methods for positioning an intracranial device are disclosed. Certain embodiments of the invention encompass devices configured for implantation within the body that include elements responsible for detecting and transmitting electrical activity from the surrounding tissues and fluids. The system may include associated hardware and software designed for transmitting, processing, analyzing, and displaying relevant aspects of detected electrical activity. This information can be used throughout or following an insertion procedure to optimize or confirm device position within a particular intracranial location or tissue compartment.

Description

technical field [0001] The present invention includes a system and method for placing and confirming the position of an intracranial device through detection of brain activity. The systems and methods provide real-time information to physicians and / or neurosurgeons during device placement in a patient and optimize the subsequent function of the device and / or the ability of the device to provide physiological monitoring within a particular tissue of interest. Background technique [0002] In the discussion that follows, certain articles and methods are described for background and introductory purposes. Nothing herein should be construed as an "admission" of prior art. Applicants expressly reserve the right, where appropriate, to demonstrate that the articles and methods cited herein do not constitute prior art under applicable law. [0003] Brain injury is often complicated by the development of secondary physiological changes within hours / days of the initial injury. Such...
