Abstract

A needle includes a hub and an elongate body. The elongate body has a proximal portion joined to the hub and defining a proximal end, a distal portion opposite the proximal portion and defining a distal end, and an intermediate portion between the proximal portion and the distal portion and having a first end adjacent the proximal portion and a second end adjacent the distal portion. A lumen extends longitudinally through the elongate body. The proximal portion extends linearly along a longitudinal axis and has a proximal diameter. The distal portion is curved to space the distal end away from the longitudinal axis and has a distal diameter that is less than the proximal diameter. The intermediate portion tapers in outer diameter going from the first end to the second end.
