ABSTRACT:
A method for forming a needle assembly is provided. A distal portion of the needle can be formed of a first material which does not interfere with MRI imaging of a tissue receiving port disposed in the distal needle portion. A proximal needle portion can be formed of a second, different material, such as a metal. The proximal needle portion can provide strength and stiffness.
