Abstract
Methods and apparatuses for blood clot aspiration. Described are fluid management components and assemblies for blood clot extraction from a patient's body and for filtering blood and recirculating blood back into the patient's body.
Claims20
A blood clot aspiration system, comprising:
- an aspiration catheter configured to aspirate blood from a patient's vasculature;
- a clot capture chamber configured to receive the aspirated blood from the aspiration catheter and to capture and contain at least some blood clots from the blood;
- a reservoir configured to receive blood from the clot capture chamber, wherein the reservoir includes a filter that is configured to filter the blood received from the clot capture chamber;
- a blood return syringe configured to receive filtered blood from the reservoir and to inject the filtered blood into the patient's vasculature;
- and
- a vent system comprising:
- a common vent line that is configured to fluidly couple the reservoir, the clot capture chamber and the blood return syringe;
- a syringe vent valve configured to allow venting of the blood return syringe to the common vent line to equalize a pressure among the blood return syringe, the clot capture chamber and the reservoir;
- and
- a clot capture vent valve configured to allow venting of the clot capture chamber to an external atmosphere;
- wherein the clot capture chamber includes a lid that is spring-loaded to automatically open the lid when the clot capture chamber is vented to the surrounding environment.

A method for removing blood clot material, the method comprising:
- aspirating blood with the blood clot material from a patient's vasculature using an aspiration catheter, wherein:
- a clot capture chamber receives the aspirated blood from the aspiration catheter and captures at least some of the blood clot material from the aspirated blood within the clot capture chamber;
- a reservoir receives blood from the clot capture chamber, wherein the reservoir includes a filter that is configured to filter the blood received from the clot capture chamber;
- opening a syringe vent valve to allow venting of a blood return syringe to a common vent line that fluidly couples the reservoir, the clot capture chamber and the blood return syringe, wherein opening the syringe vent valve equalizes a pressure among the blood return syringe, the clot capture chamber and the reservoir;
- drawing filtered blood into the blood return syringe from the reservoir while the syringe vent valve is open;
- injecting the filtered blood into the patient's vasculature from the blood return syringe;
- opening a clot capture vent valve to allow venting of the clot capture chamber to an external atmosphere, and opening a lid of the clot capture chamber to allow access to a removable tray, wherein the removable tray is configured to capture clots therein, wherein the lid automatically opens upon actuation of the clot capture vent valve.
