Abstract:
1. A method of manufacturing a medical apparatus, comprising: obtaining a core having a length, a longitudinal axis, and a resistivity, the resistivity being less than 20 micro-ohms per centimeter; and winding a filament around substantially the length of the core to form a coil that is electrically coupled to the core, the filament being formed of a biocompatible alloy having an ultimate tensile strength of between 150 kilo pounds per square inch (ksi) and 280 ksi at room temperature, wherein turns of the coil are disposed at an angle of between 0 and 45 degrees relative to an axis that is substantially perpendicular to the longitudinal axis of the core; wherein winding the filament comprises winding the filament to be directly adjacent to the core.
