1. An implantable lead system, comprising:
- an elongated lead body defining a longitudinal axis and comprising an electrical conductor extending between a distal end of the lead body and a proximal end of the lead body;
an electrode mounted on the distal end of the lead body, the electrode being coupled to the electrical conductor;
one or more passive fixation mesh sections coupled to the lead body that encourage tissue over growth and is adapted to transition between a collapsed state wherein it is at least partially wrapped around the lead body and an extended state wherein it projects outward from the lead body; and
one or more contact points integrated on the lead body, the contact points being adapted to promote overgrowth of cardiac tissue thereon;
wherein a shape of at least one of the one or more passive fixation mesh sections is asymmetric about the longitudinal axis of the lead body when in an extended state.

Abstract
An implantable lead having an elongated lead body that includes an electrical conductor extending between a distal end of the lead body and a proximal end of the lead body is disclosed. The lead further includes an electrode formed at the distal end of the lead body, the electrode being coupled to the electrical conductor and one or more passive fixation mesh sections coupled to the distal end of the lead body that promotes tissue over growth.
