Adjacent helical electrodes may be offset, for example, 90 degrees or 180 degrees. The helical electrodes may extend less than, greater than, or 360 degrees. The electrode arrangement provides increased surface area, improving the capability of positioning the lead against the nerve as desired. | 2012-03-29 |
20120078333 | MEDICAL LEAD SYSTEM UTILIZING ELECTROMAGNETIC BANDSTOP FILTERS - Medical lead systems utilizing electromagnetic bandstop filters are provide which can be utilized in a magnetic resonance imaging (MRI) environment for patients who have implanted medical devices. The medical lead system includes an implanted lead having at least one bandstop filter associated therewith, for attenuating current flow through the lead over a range of frequencies. The bandstop filter has an overall circuit Q wherein the resultant 3 dB bandwidth is at least 10 kHz. The values of capacitance and inductance of the bandstop filter are selected such that the bandstop filter is resonant at a selected center frequency. Preferably, the bandstop filter has an overall circuit Q wherein the resultant 10 dB bandwidth is at least 10 kHz. Such bandstop filters are backwards compatible with known implantable deployment systems and extraction systems. | 2012-03-29 |
