A multipolar cannula, comprising: a cannula tube, which has a distal end and a proximal end; a first electrode; and at least one second electrode. The cannula tube has a cannula tube body and a coating, which electrically insulates the first and the second electrode from one another. The distal end of the cannula tube has a distal tip, and an attachment is arranged on the proximal end, which attachment has an electrically contacting connection point for the electrodes. The electrically insulating coating and at least the second electrode are applied to the cannula tube body in a thin-film process.

A flame retardant is included in a resin phase, and the flame retardant has a maximum number frequency in a range of 1 μm or less when a particle size distribution is evaluated by dividing a particle size into 1 μm increments. The resin phase includes inorganic particles, and the inorganic particles have a maximum number frequency in a range of 0.5 μm or less when the particle size distribution is evaluated by dividing the particle size into 0.5 μm increments. The flame retardant has an average particle size larger than the average particle size of inorganic particles. The number frequency of the flame retardant and the inorganic particles, respectively, decreases with increasing the particle size.

The method of manufacturing the insulation member includes manufacturing a 3D printing material using a mixed material in which one or more materials selected from among polycarbonate (PC), polybutylene terephthalate (PBT), acrylonitrile-butadiene-styrene (ABS), polyamide (PA), polyoxymethylene (POM), and polyethylene terephthalate (PET), one or more fillers selected from among TiO2, SiO2, and AlO3, and a curing agent are mixed, and which contains different amounts of the fillers at predetermined intervals in a longitudinal direction, and sequentially stacking the manufactured 3D printing material using a 3D printer to thus manufacture a target insulation member so that the mixed material containing different amounts of the fillers at predetermined intervals in a longitudinal direction of the insulation member is sequentially stacked.

A method of producing the fibrillated liquid crystal polymer powder. A resin multilayer substrate obtained by laminating a plurality of resin sheets including at least one layer of a liquid crystal polymer sheet. On a surface of at least one layer of the liquid crystal polymer sheet, a thickness adjustment layer made of a fibrillated liquid crystal polymer powder containing fibrillated liquid crystal polymer particles is provided in a region insufficient in thickness when at least the plurality of resin sheets are laminated.

Logic mechanisms operate to define the position of at least one mechanical output based on the position of at least one mechanical input. Some mechanisms are configured to determine, based on the input position(s), whether a path to transmit motion to an output exists or does not exist. Some mechanisms are configured to determine, based on the input position(s), whether or not motion of a driven element can be accommodated without moving an output. Some mechanisms are configured to determine, based on the input position(s), whether or not one or more elements are constrained to transmit motion to an output.

Mechanisms can be designed to manage non-contact forces to reduce energy consumption and/or to control interactions between the parts. Management of non-contact forces is especially useful in micro-scale and nano-scale mechanisms, where van der Waals attraction between parts of the mechanism may be significant to the operation of the mechanism.

Logic mechanisms operate to define the position of at least one mechanical output based on the position of two or more mechanical inputs, and employ at least one control element that functions to determine (at least in part) whether an output is moved, and which provides the same function in more than one position. Some mechanisms are configured to determine, based on the input positions, whether a path to transmit motion to an output exists or does not exist. Some mechanisms are configured to determine, based on the input positions, whether or not motion of a driven element can be accommodated without moving an output.

The present disclosure relates to connectors for high density neural interfaces and methods of microfabricating the connectors. Particularly, aspects of the present disclosure are directed to a connector having a core and a supporting structure wrapped around at least a portion of the core. The supporting structure may have a first layer of a high temperature liquid crystal polymer, and the second layer of a low temperature liquid crystal polymer that is reflowed to attach the supporting structure to the core. Conductive traces are buried between the first layer and the second layer, and the conductive traces terminate at conductive contacts formed on a surface of the first layer. The connector may have a predetermined shape or profile, which facilitates alignment and insertion of the connector into a header of a neurostimulator.

An assembled wire has a substantially rectangular cross section, and is formed by assembling a plurality of strands. Each strand has a conductor portion and a strand insulating layer covering the conductor portion. At least a part of the assembled plurality of strands in the longitudinal direction is covered with an outer insulating layer. The strand is formed as follows. First, the strand insulating layer is coated on the outer periphery of the conductor portion. A large number of voids are formed in a resin constituting the strand insulating layer. From this state, the strand is formed, for example, by collapsing the strand insulating layer by heating and pressurizing. At this time, it is possible to uniformly collapse the strand insulating layer by crushing the internal voids. Therefore, the voids in the strand are crushed and flattened in the thickness direction of the strand insulating layer over the entire periphery.

A submersible component can include a conductor; and a polymeric material disposed about at least a portion of the conductor where the polymeric material includes at least approximately 50 percent by weight polyether ether ketone (PEEK) and at least 5 percent by weight perfluoroalkoxy alkanes (PFA). A submersible electrical unit can include an electrically conductive winding; and a polymeric composite material disposed about at least a portion of the electrically conductive winding where the polymeric composite material includes polymeric material at at least approximately 40 percent by volume and one or more fillers at at least approximately 10 percent by volume.
