Abstract
A biopsy needle assembly comprised of an outer flexible catheter and a reciprocating interior structure on which the needle is mounted. In one embodiment, the needle is directly connected to an internal guide wire. In another, the needle is directly connected to an inner flexible catheter and the guide wire can either extend through the needle or be stopped within the needle. In each embodiment, the needle includes a lateral opening providing a fluid path from the hollow needle, through the catheter, either between the catheter and guide wire or the inner and outer catheters to an outlet at the proximal end of the assembly. The invention also relates to a syringe plunger stop end lock attachment.
