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 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.
