Abstract
The invention is directed to a system and method for separating and collecting one or more tissue specimens from a target site within a patient and flushing the specimen to remove blood, debris and the like before the specimen is removed from the biopsy device. The flow of flushing fluid to the tissue collector is preferably controlled to coincide with delivery of one or more specimens to the collecting tray or basket of the device or after the receipt of the specimen within the tissue collector to ensure that the fluid is applied to a fresh specimen. The tissue tray or basket within the tissue collector has an open or foraminous portion to facilitate removal of fluid, such as the applied fluid and blood, and other debris from the tissue specimens on the tray. Vacuum is provided within the tissue collector, preferably under the tray to remove fluid and debris from the collector interior.
