Abstract: A vitreous enamel coating for an electrosurgical metal cutting blade, in which incident light striking the vitreous enamel coating is diffusely reflected or absorbed, and the vitreous enamel coating exhibits a 60° gloss value less than 100 gloss units as measured according to ASTM D523-14, Standard Test Method for Specular Gloss. The coating reduces glare from light sources such as a nearby plasma-mediated discharge, operating theater lights or lights provided on an electrosurgery apparatus. The coating may also lessen interference with markers, sensors or other instruments designed to measure light emitted by or passing through nearby tissue such as by transillumination.

Abstract: A cutting element for an electrosurgical device. The cutting element includes an elongate non-conductive body having a first face opposite a second face, the first face and the second face defining an edge there between. A conductive element is disposed only along the edge, the conductive element being configured to cut tissue with monopolar radiofrequency energy.

Abstract: Cerebrospinal fluid (CSF) and other fluid amelioration systems completely or partially implantable within a mammalian subject and associated methods include a substrate and an agent for amelioration of a toxic biomolecule present in the CSF or fluid, wherein the agent is disposed on or within the substrate.

Abstract: A CSF management method and/or apparatus is used with a patient forms a CSF circuit having at least one pump and catheter. The CSF circuit is configured to control the flow of CSF in the patient's body. The method then flows, using the pump and the catheter, the patient's CSF at a given flow rate through the CSF circuit, and monitors, using a pressure sensor, the intracranial pressure in the craniospinal compartment of the patient when flowing CSF through the CSF circuit. For safety purposes, the method controls the given flow rate of the CSF in the CSF circuit as a function of the monitored intracranial pressure in the craniospinal compartment.

Abstract: A CSF management method for use with a patient forms a closed loop CSF circuit between two points on the patient's body. The CSF circuit has a therapeutic inlet to receive a therapeutic material (e.g. a drug), and a pump having a pump outlet to direct CSF along the CSF circuit. The method controls the pump to direct CSF from the pump outlet at a CSF rate that is different from the natural flow rate (i.e., the natural CSF flow rate). The therapeutic material is added to the CSF via the therapeutic input at a therapeutic rate. The CSF rate is different than the therapeutic rate and/or may be greater than the therapeutic rate. Alternative methods may control a bolus drug infusion to localize the application to a target region.

Abstract: A colored (viz., not black) vitreous enamel coating for an electrosurgical metal cutting blade provides heat-resistant, durable blade coloration and facilitates differentiation or discrimination between, or identification of, different blades. Different colors may be employed on different blade shapes in an array of blades, on blades used for different surgical procedures, or on blades used on different tissue types. The color may be applied to a portion of a blade to denote an edge or other feature. The color may preferentially absorb the primarily blue-trued light emitted by an electrosurgery plasma and preferentially reflect light of other hues; make the blade more visible against surrounding tissues; or discourage reflection of visible or other light (e.g., infrared radiation) in colors that might interfere with markers, sensors or other instruments designed to measure light emitted by or passing through nearby tissue such as by transillumination.
