Patent ID: 8483840

Claim:
An active implantable medical device (AIMD) comprising a dual function passive component input filter network, the active implantable medical device comprising: a) an electromagnetically shielded AIMD housing; b) at least one electronic sensing or therapy delivery circuit disposed within the AIMD housing; c) a first conductive path having a primary series inductance and extending from a first conductive path first end at the at least one electronic sensing or therapy delivery circuit to a first conductive path second end at a feedthrough connected to the AIMD housing, the feedthrough connectable to an implantable lead; and d) a second conductive path having a primary series capacitance and extending from a second conductive path first end connected anywhere along the first conductive path between the primary series inductance and the at least one electronic sensing or therapy delivery circuit to a second conductive path second end connected to the AIMD housing, e) wherein the primary series capacitance and the primary series inductance comprise an L-section broadband low pass electromagnetic interference (EMI) filter configured to protect the electronic sensing or therapy delivery circuit; and f) wherein the primary series inductance and the primary series capacitance also form a resonant L-C trap filter between the first conductive path second end to the second conductive path second end configured to divert RF energy induced at the feedthrough at the second end of the first conductive path to the AIMD housing.
