Systems and methods for anchoring implanted sensors to various body structures is also provided.
Claims30
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.

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
- means for anchoring said lead system to an organ wall in a body, wherein said means for anchoring is configured to change shape from a first state to a second state, and wherein the means for anchoring comprises at least one non-linear tissue ingrowth path.
