COLLAPSIBLE/EXPANDABLE TUBULAR ELECTRODE LEADS

摘要

A medical lead comprising an electrically insulative tubular membrane, a
resilient spring element associated with the insulative membrane, and at least
one electrode associated with the insulative membrane. The tubular membrane
may have a non-circular cross-sectional shape. The spring layer is configured
to urge that insulative membrane into an expanded geometry. The medical lead
may be configured to be collapsed into a compact form for percutaneous
delivery into the patient.
