1. A clot collection reservoir, comprising:
a housing defining a sealed chamber and having a first housing end portion and a second housing end portion opposite the first housing end portion;
a first port configured to be fluidly coupled to an aspiration catheter, wherein the first port is positioned proximate to the first housing end portion and provides a first fluid path to the chamber;
a second port configured to be fluidly coupled to an aspiration source, wherein the second port provides a second fluid path from the chamber; and
a filter removably positioned within the chamber, wherein the filter has a substantially cylindrical shape extending from a first filter end portion to a second filter end portion, and wherein the filter extends continuously about the first filter end portion such that the filter encloses an interior region around the second port;
wherein the aspiration source is configured to generate negative pressure in the chamber via the second port to (a) draw blood and clot material from the aspiration catheter through the first port into the chamber and (b) draw blood through the filter into the interior region and through the second port;
wherein the filter is configured to inhibit the clot material from passing through the filter into the interior region and through the second port; and
wherein the housing is at least partially transparent to permit visualization of the clot material in the chamber outside the interior region.
