Abstract

A needle assembly (10) comprising an infusion needle (11) that includes a needle cannula (13) made of a superelastic material such as nitinol. The needle cannula is cold-worked or heat annealed to produce a preformed bend (16) that can be straightened within passageway (21) of a coaxial outer cannula (12) for introduction into the body of a patient. Upon deployment from the outer cannula, the needle cannula substantially returns to the preformed configuration for the introduction or extraction of materials at areas lateral to the entry path of the needle assembly. The needle assembly can comprise a plurality of needle cannulae that can be variably arranged or configured for attaining a desired infusion pattern.
