Abstract

A novel instrument (10) for automatic sampling or percutaneous removal of tissue from a patient is disclosed. In one embodiment the instrument (10) comprises a housing (20), a stylet (23), and a cannula (28) for excising tissue from a target site within a patient's body extending from the housing (20); means for impelling (26) the stylet (23) and the cannula (28) into a target tissue site in response to an impelling force wherein the impelling means (26) is contained within the housing (20) and is in fluid communication with a source of compressed fluid; and wherein fluid from the source of compressed fluid provides the impelling force.
