Patent number: 9071221Abstract: A composite RF current attenuator for a medical lead includes a conductor having a distal electrode contactable to biological cells, a bandstop filter in series with the lead conductor for attenuating RF currents flow through the lead conductor at a selected center frequency or across a range of frequencies about the center frequency, and a lowpass filter in series with the bandstop filter and forming a portion of the lead conductor. The bandstop filter has a capacitance in parallel with a first inductance. In a preferred form, the lowpass filter includes a second inductance in series with the bandstop filter, wherein the values of capacitance and inductances for the composite RF current attenuator are selected such that it attenuates MRI-induced RF current flow in an MRI environment.Type: GrantFiled: March 26, 2015Date of Patent: June 30, 2015Assignee: Greatbatch Ltd.Inventors: Robert A. Stevenson, Robert Shawn Johnson, Kishore Kumar Kondabatni, Joseph E. Spaulding, Dominick J. Frustaci, Warren S. Dabney, Holly Noelle Moschiano

Patent number: 8792987Abstract: Deep brain electrodes are remotely sensed and activated by means of a remote active implantable medical device (AIMD). In a preferred form, a pulse generator is implanted in the pectoral region and includes a hermetic seal through which protrudes a conductive leadwire which provides an external antenna for transmission and reception of radio frequency (RF) pulses. One or more deep brain electrode modules are constructed and placed which can transmit and receive RF energy from the pulse generator. An RF telemetry link is established between the implanted pulse generator and the deep brain electrode assemblies. The satellite modules are configured for generating pacing pulses for a variety of disease conditions, including epileptic seizures, Turrets Syndrome, Parkinson's Tremor, and a variety of other neurological or brain disorders.Type: GrantFiled: April 8, 2013Date of Patent: July 29, 2014Assignee: Greatbatch Ltd.Inventors: Robert A.
