Patent ID: 8784382

Claim:
A needle assembly, comprising: an outer needle cannula having a distal opening; a multi-needle subassembly received within said outer needle cannula, said subassembly comprising a base cannula and a plurality of needle cannulae having proximal portions manifolded into and affixed in place within said base cannula to fix distal tip portions of said needle cannulae in an array extending distally of a distal end of said base cannula, said multi-needle subassembly slidable within said outer needle cannula to selectively deploy said array from said distal opening of said outer needle cannula; and said needle cannulae each having a passageway, and each said needle cannula, while in its unconstrained configuration, having at least one preformed bend proximate to said distal tip portion and being constrainable to a second configuration, whereby at release of external constraining forces, said distal tip portion of each said needle cannula substantially returns to the unconstrained configuration extending forwardly and radially outwardly from a respective said preformed bend.
