Abstract: 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.

Abstract: One or more inductors and one or more capacitors are physically disposed relative to one another in series and are electrically connected to one another in parallel to form a bandstop filter. Chip inductors and chip capacitors having spaced apart conductive terminals are physically arranged in end-to-end abutting relation to minimize electrical potential between adjacent conductive terminals. The bandstop filter may be hermetically sealed within a biocompatible container for use with an implantable lead or electrode of a medical device. The values of the inductors and the capacitors are selected such that the bandstop filter is resonant at one or more selected frequencies, such as an MRI pulsed frequency.

Abstract: An identification device for an implantable lead includes an associated implantable sleeve and a radio frequency identification device (RFID) tag associated with the sleeve. The RFID tag includes information relating to the implantable lead, its associated lead system, or an associated implantable medical device. The RFID tag may be hermetically sealed within the sleeve and the sleeve selectively fixed along a length of the lead. The sleeve may comprise a loop forming an aperture, a crimped clamp device, a clamp device including a ratchet, clip, or rivet mechanism, or a clamp device including two separate clamshells, all of which allow for secure attachment to the lead. Alternatively, the sleeve may integrally be formed as part of the lead between a lead conductor and an insulated lumen. An external interrogator may be used for identifying information contained within the RFID tag.

Abstract: A TANK filter is provided for a lead wire of an active medical device (AMD). The TANK filter includes a capacitor in parallel with an inductor. The parallel capacitor and inductor are placed in series with the lead wire of the AMD, wherein values of capacitance and inductance are selected such that the TANK filter is resonant at a selected frequency. The Q of the inductor may be relatively maximized and the Q of the capacitor may be relatively minimized to reduce the overall Q of the TANK filter to attenuate current flow through the lead wire along a range of selected frequencies. In a preferred form, the TANK filter is integrated into a TIP and/or RING electrode for an active implantable medical device.

Abstract: An RFID tag is disposed within a hermetically sealed housing of an IMD. Low frequency RFID interrogators and tags are used, and the housing walls are made of materials, and/or are reduced in thickness, to facilitate RF communication between the RFID tag and an RFID reader/interrogator programmer. An RFID reader/interrogator may be used which has a limited transmit time and time-out period to avoid interference with the operation of the IMD.
