Abstract
A biopsy system includes a biopsy device, a vacuum canister, a vacuum control module, and a plurality of tubes. A first tube is configured to provide an axial vacuum to the biopsy device, while a second tube is configured to provide a lateral vacuum. A third tube is configured to communicate atmospheric air to the second tube. A fourth tube is configured to communicate saline to the second tube. The vacuum canister is configured to collect fluids drawn through the first tube and the second tube. The canister has a lid with trenches formed in it for retaining the first, second, third, and fourth tubes. The lid also has engagement regions for selectively pinching each of the tubes against to prevent fluid communication through selected tubes. The canister can be removably inserted into the vacuum control module, which includes components for selectively pinching the tubes against the engagement regions.
