Biopsy instrument having aspiration capabilities

A biopsy instrument for retrieving a tissue sample from a patient, comprising:

• a tubular member having proximal and distal ends, the tubular member including an aspiration conduit adapted to provide a conduit through which a fluid flows and through which the tissue sample is aspirated from the patient;
• a distal end effector assembly coupled to said distal end of said tubular member and adapted to detach the tissue sample from the patient;
• a proximal actuation handle coupled to the proximal end of the tubular member;
• and
• a sample catch assembly coupled to said aspiration conduit and adapted to receive the tissue sample from said aspiration conduit, said sample catch assembly including a chamber and a sample catch member adapted to separate the tissue sample from the fluid, said chamber having a first opening to receive the fluid, a second opening to discharge the fluid from the chamber, and a third opening to removably receive said sample catch member.
