Abstract
A medical lead and method of treating a patient are provided. The medical lead comprises an electrically insulative membrane, a resilient spring element associated with the insulative membrane, and at least one electrode associated with the insulative membrane. The spring layer is configured to urge that insulative membrane into an expanded geometry. The medical lead is configured to be collapsed into a compact form for percutaneous delivery into the patient, thereby obviating the need to perform an invasive surgical procedure on the patient. The patient can be treated by placing the medical lead into a collapsed state by applying a compressive force to the medical lead, percutaneously delivering the collapsed medical lead into the patient adjacent tissue to be treated, and placing the medical lead into an expanded state by releasing the compressive force.
