MRI-COMPATIBLE IMPLANTABLE LEAD WITH IMPROVED LC RESONANT COMPONENT
First Claim
1. An implantable lead, comprising:
- a lead body extending along a longitudinal axis, the lead body including a distal end and a proximal end, and a lumen within the lead body;
a header assembly provided at the distal end of the lead body, the header assembly including a tissue engaging end;
an electrode provided on the header assembly, the electrode configured to deliver stimulating pulses;
an electrode conductor provided within the lumen of the lead body and extending from the electrode to the proximal end of the lead body; and
an LC resonant component provided in at least one of the lead body and the header assembly, the LC resonant component comprising;
a capacitor having an elongated shape that extends along the longitudinal axis of the lead body, the capacitor having a core that is located about the longitudinal axis of the lead body; and
an inductor wire wound in multiple turns about an exterior surface of the capacitor to form an inductor.

Abstract
An implantable lead is provided that comprises a lead body extending along a longitudinal axis. The lead body includes a distal end and a proximal end and a lumen within the lead body. The lead also includes a header assembly provided at the distal end of the lead body. The header assembly includes a tissue engaging end. The lead also includes an electrode provided on the header assembly. The electrode is configured to deliver stimulating pulses. The lead also includes an electrode conductor provided within the lumen of the lead body and extending from the electrode to the proximal end of the lead body. An LC resonant component is provided in at least one of the lead body and the header assembly. The LC resonant component comprises a capacitor having an elongated shape that extends along the longitudinal axis of the lead body. The capacitor has a core that is located about the longitudinal axis of the lead body. The LC resonant component further comprises an inductor wire wound in multiple turns about an exterior surface of the capacitor to form an inductor.
