Durable fine wire lead for therapeutic electrostimulation and sensing
摘要:
A cardiac pacemaker, other CRT device or neurostimulator has one or more fine wire leads. Formed of a glass, silica, sapphire or crystalline quartz fiber with a metal buffer cladding, a unipolar lead can have an outer diameter as small as about 300 microns or even smaller. The buffered fibers are extremely durable, can be bent through small radii and will not fatigue even from millions of iterations of flexing. Bipolar leads can include several conductors side by side within a glass/silica fiber, or can be concentric metal coatings in a structure including several fiber layers. An outer protective sheath of a flexible polymer material can be included.
