A thrombus filter has a sheath, a thrombus intercepting net having an intercepting port, and an overfill prevention umbrella being a meshed structure that always surrounds the entire thrombus intercepting net. The overfill prevention umbrella has an umbrella stand and an umbrella surface, and is self-biased such that, at body temperature, the umbrella surface is configured to always converge towards the center of the intercepting port. The thrombus filter assumes a first position when the thrombus intercepting net is released from the sheath, where the distal opening of the overfill prevention umbrella is pushed open by the intercepting port. The thrombus filter assumes a second position when the thrombus intercepting net is retrieved into the sheath, where the umbrella surface converges towards the center of the intercepting port, and the open end of the umbrella surface is constricted to prevent the thrombus from escaping.
