Claims11
A tissue trap for use with a tissue removal device having a fluid outflow connector configured to direct waste fluid to a waste fluid collection reservoir, said tissue trap comprising:
- a collector housing having (a) a fluid inflow port configured to receive waste fluid from the fluid outflow connector of the tissue removal device and (b) a fluid outflow port configured to direct filtered waste fluid to the fluid collection reservoir;
- a collector vial having an inlet end, and outlet end, and a filter member therebetween;
- and
- a carrier disposed in an interior of the collector housing, said carrier configured to (a) removably carry the collector vial and (b) move between (i) a first position where the inlet and outlet ends of the collector vial are aligned with the fluid inflow and outflow ports of the collector housing to allow fluid flow, filtration, and collection and (ii) a second position where at least the fluid inflow port of the collector housing is sealed to block fluid flow from the fluid outflow connector.
