Claim 0:
1. A vacuum aspiration system, comprising:
a housing comprising:
a side wall at least partially defining a clot container having a distal end portion and a proximal end portion;
a hemostasis valve;
a fluid flow path extending through the clot container; and
an on-off control in the flow path, the on-off control being configured to regulate aspiration through the flow path; and

a first catheter having a proximal end portion, a distal end portion, and an aspiration lumen extending from the proximal end portion to the distal end portion and in fluid communication with the flow path; and
a connector configured to place a source of aspiration in communication with the flow path,
wherein the aspiration lumen has a substantially constant diameter,
wherein the proximal end portion of the first catheter is fixedly coupled to the hemostasis valve,
wherein the distal end portion of the first catheter is sized and shaped to be positioned proximate to clot material within a blood vessel of a patient such that negative pressure generated by the aspiration source aspirates at least a portion of the clot material into the distal end portion of the first catheter and into the aspiration lumen,
wherein the first catheter is distal of the clot container,
wherein the aspiration source is proximal of the clot container,
wherein the hemostasis valve is configured to receive a second catheter and direct the second catheter through the first catheter, and
wherein the second catheter is configured to be removably received within and axially translated through the first catheter.
