| 1. A physiological lead system, comprising:
an elongate member having a proximal end and a distal end;
a lead located generally at the distal end of said elongate member; and
a distal anchor assembly engaged to said elongate member, said distal anchor assembly comprising at least one protruding member,
said distal anchor assembly configured to change shape from a first state to a second state,
wherein the at least one protruding member is substantially parallel to a longitudinal axis of the distal anchor assembly
in the first state and bent at an angle with respect to the longitudinal axis of the distal anchor assembly in the second
state, and
wherein the at least one protruding member further comprises at least one non-linear tissue ingrowth path.
