Abstract
Techniques related to coils for medical device are disclosed. One example coil may comprise multiple filars, each being formed of a biocompatible beta titanium alloy having an elastic modulus ranging from 30 GigaPascals (GPa) to 90 GPa and comprising at least two elements from a group consisting of titanium, molybdenum, niobium, tantalum, zirconium, chromium, iron and tin. At least one of the multiple filars may be electrically insulated one from another. A structural body, such as a lead body, may carry the coil. One or more filars may carry a low-resistance core.
