Manual clot aspiration and filtration system and method of removing a clot

An aspiration and filtration system for bodily fluid comprising:

• a) an inlet-sheath;
• b) an inlet one-way valve coupled to the inlet sheath;
• c) a return-sheath;
• d) a return one-way valve coupled to the return sheath;
• e) a filter unit comprising:
• i) a filter housing having an inlet and an outlet;
• ii) a filter configured in the filter housing between the inlet and outlet;
• iii) a cover that is detachably attachable to the filter housing;
• wherein the filter unit is configured to receive said bodily fluid into the inlet from a patient and wherein said bodily fluid is configured to flow through the filter to the outlet of the filter unit, wherein the filter filters particles from the bodily fluid between the inlet and the outlet within the filter housing;
• wherein the filter is separate from the filter housing and the cover;
• wherein the filter is removable from the filter housing by removing the cover;
• f) a purge valve coupled to the filter housing cover and having an outlet opening configured above the filter housing to enable purging trapped air from the filter unit with bodily fluid contained within the filter unit;
• g) a syringe comprising a plunger within a barrel, wherein the syringe is configured between the filter unit and the return-sheath;
• h) a flow-valve coupled with the syringe;
• wherein the flow-valve is configured between the filter unit and the return-sheath and is configured for turning from an inlet flow configuration to a purge flow configuration;
• wherein the flow-valve has said inlet flow configuration for drawing said bodily fluid through the inlet-sheath, through the filter housing and into the syringe, whereby debris from the bodily fluid is collected by the filter;
• wherein the flow-valve has said purge flow configuration for forcing said bodily fluid from the syringe into the filter unit and air out of the outlet opening of the purge valve;
• and
• wherein the flow-valve has a return flow configuration for forcing said bodily fluid from the syringe into the return-sheath;
• wherein the return sheath is a separate sheath from the inlet-sheath, and wherein the return sheath is configured between the outlet of the filter housing and said patient;
• and
• wherein the said particles are configured to be removed from the filter housing with the bodily fluid retained in the filter housing.
