Claim 0:
1. A robotically controlled system for removing a clot from a patient comprising:
an instrument system including:
a first elongate member;
a second elongate member positioned coaxially with the first elongate member,
wherein the second elongate member includes at least one articulation cable and is coupled to a pump for performing an aspiration function on the clot,
wherein the first and second elongate members each have at least one articulation cable for bending the respective one of the first or second elongate members,
wherein the first elongate member has a greater number of articulation cables than the second elongate member, and
wherein the first elongate member is capable of being articulated independently from the second elongate member; and

a third elongate member that is positioned within the first elongate member and the second elongate member, wherein the third elongate member comprises:
a blunt distal tip configured to pierce the clot;
a clot cutter configured to reduce the clot to smaller particles; and
a distal guard configured to be robotically deployed distal to the clot to prevent the smaller particles of the clot from being distributed downstream in the patient;

and
a retriever coupled to the second elongate member and configured to capture the clot and the smaller particles of the clot; and

an instrument drive system for driving the instrument system, wherein the instrument drive system comprises a first instrument driver for driving the first elongate member and a second instrument driver for driving the second elongate member.
