The invention relates to a needle having a lumen for distributing fluid into, or removing fluid from, a soft tissue of a patient. The needle includes a nickel-titanium alloy. The needle is treated with an acidic solution including hydrofluoric acid at a temperature less than 60 C. for at least 10 seconds.

There is provided a needle comprising a needle tube extending along a central axis between proximal and distal ends of the needle, the needle tube defining a lumen, and the distal end defining an opening into the lumen. The needle comprises a point, a cutting edge, and a heel extending between inner and outer surfaces of the needle tube. At least a region of the heel extends substantially orthogonally to the central axis to provide a non-cutting edge of the distal end.

Disclosed herein are implementations of a device, and associated methods and systems, for bending and securing a surgical needle to a predetermined angle relative to the base of the needle. One feature of various disclosed implements of the invention is a two-part construction that provides additional needle stability after bending.
