Abstract

A vascular access needle assembly includes a housing interconnected with a needle. The housing and the needle have slots along their lengths that are aligned to form a slot extending along the entire needle assembly. A movable sheath interconnected with the needle extends partially about the needle, and includes a slot. In one position where the needle point is exposed and needle slot is closed, the vascular access needle can be inserted into the blood vessel of a subject so that a guide wire can be inserted into the blood vessel through the needle assembly. The sheath is then moved to cover the needle point and to expose the needle slot so that the guide wire can be lifted through the needle, sheath and housing slots and the vascular access needle assembly removed, leaving the guide wire in the subject. The device is operable as a wire introduces for catheters. The vascular needle assembly is adapted for use as a biopsy needle to obtain biopsy tissue by sharpening the edges of one or both of the needle slot and sheath slot to cut tissue.
