1. Apparatus for disrupting a clot in a blood vessel, the apparatus comprising:
a catheter body having a proximal length and a treatment length, the treatment length being configured to be disposed within a patient;
at least one port along the proximal length of the catheter body;
at least one infusion opening along the treatment length of the catheter body;
at least one aspiration opening along the treatment length of the catheter body;
a first lumen within the catheter body in fluid communication with the at least one infusion opening and in fluid communication with the at least one aspiration opening;
a valve member configured to be disposed, in its entirety, within the treatment length of the catheter body, the valve being configured to selectively open and close fluid communication between the at least one port and the at least one aspiration opening, wherein the valve member comprises a body that is translatable longitudinally within the first lumen, and wherein the body of the valve member comprises a first position located proximally of the at least one aspiration opening and a second position located distally of the at least one aspiration opening; and
an agitator that is translatable longitudinally within the first lumen, wherein the agitator comprises the valve member.
