ABSTRACT:
An automated device for obtaining a tissue biopsy and delivering material to provide hemostatis, therapeutic agents or marker material is described. The device has an outer casing, a power source, a drive mechanism, an application chamber through which the biopsy mechanism, typically a cutting needle, passes through and an application channel. The cutting biopsy mechanism has a mechanical or electromechanical mechanism to rapidly fire a stylet with a biopsy trough into the intended tissue and then rapidly propel a biopsy cannula over the stylet to sever and retain tissue that has protruded into the biopsy trough. At least one application channel is formed by a tube centrically slipped over the biopsy cannula wall. To enable the collection of tissue specimens, the distal segment of the application channel forms a close fitting and concentric sheath around the biopsy cannula.
