Assignee:
NeuroPace, Inc. - Mountain View CA
International Classification:
A61N 1/00
US Classification:
607116
Abstract:
Medical electrical lead systems and related methods are described. The lead systems may be configured to be at least partially implanted in neural tissue of a subject, such as a brain of a subject. Some variations of the lead systems may comprise a lead body, an electrode connected to the lead body, and a bioactive agent. The electrode and/or lead body may comprise a substrate, and the bioactive agent may be supported by the substrate (e. g. , by a substantial portion of the area of the substrate). Examples of bioactive agents that may be used in the lead system include antiproliferative agents, bactericidal agents, bacteriostatic agents, antiepileptic agents, and/or antifungal agents. Methods described herein may comprise coating a lead body and/or an electrode of a medical electrical lead system with at least one bioactive agent, where the lead body and the electrode are connected to each other.

International Classification:
G09G005/00
US Classification:
345/611000
Abstract:
A graphics system may be configured to render anti-aliased dots in terms of samples and to generate pixels by filtering the samples. The pixels are supplied to one or more display devices. The means used to generate the samples may perform the computation of radial distance at positions on a grid in a rendering coordinate space, and interpolate estimates for the radial distances of samples around the dot as needed based on the radii at the grid positions.

Medical electrical lead systems and related methods are described. The lead systems may be configured to be at least partially implanted in neural tissue of a subject, such as a brain of a subject. Some variations of the lead systems may comprise a lead body, an electrode connected to the lead body, and a bioactive agent. The electrode and/or lead body may comprise a substrate, and the bioactive agent may be supported by the substrate (e.g., by a substantial portion of the area of the substrate). Examples of bioactive agents that may be used in the lead system include bioactive agents that promote neural adhesion and living cells that have been biologically manipulated, engineered cells, and cells of a particular phenotype and/or adapted to induce a desired neural or glial response. Methods described herein may comprise contacting the substrate of a lead body and/or an electrode of a medical electrical lead system with at least one bioactive agent, where the lead body and the electrode are connected to each other.

Abstract:
Methods, devices, and systems induce neuromodulation by focusing a source of stimulation through a skull/brain interface in the form of an aperture formed in the skull, a naturally occurring fenestration in the skull, or a transcranial channel. Methods, devices, and systems identify where to locate skull/brain interfaces, accessories that can be used with the interfaces, and features for controlling stimulation delivered through the interfaces. Multiple indications for the skull/brain interfaces include diagnosis and treatment of neurological disorders and conditions such as epilepsy, movement disorders, depression, Alzheimer's disease, autism, coma, and pain.
