Methods and apparatus according to the disclosure include without limitation the following. A method for providing fault tolerance to an active implantable medical device (AIMD) coupled via a medical electrical lead to an implantable physiologic sensor (IPS), including a conductive member or structure for imparting a biasing force to a proximal portion of the lead. The conductive member electrically couples to a source of reference electrical potential (i.e., electrical ground) and neither contacts nor conducts a source of power for the IPS. The conductive member can include threads and interlocking tool-receiving portions and can be shielded from contact with body fluid(s) by a seal-healing grommet or septum. Furthermore, a set screw can serve as the conductive member and the set screw can include an Allen wrench receptacle or a screwdriver receptacle or equivalent. |
