Methods and devices for bending a needle are provided. A device embodiment can include a needle bending apparatus for imparting a bend in a needle when a needle is received therein. The needle bending apparatus may include a housing having an aperture for receiving a shaft of a needle; and at least one abutment member comprising a needle interfacing surface for supporting a portion of the needle and providing a surface upon which the needle may be bent.

A needle member includes: a tubular side wall through which a hollow portion extends in a longitudinal direction. An opening portion connected to the hollow portion extends laterally through the tubular side wall. The tubular side wall comprises a side wall reinforcement portion located at a position opposing the opening portion, wherein the hollow portion is interposed between the opening portion and the side wall reinforcement portion.

A needle bender for custom bending of needles to different desired needle bend radii is provided. The needle bender can include abase and a shaper coupled to the base through a support member. The shaper may have a plurality of grooves corresponding to different desired needle bend radii. A leverage arm with a needle slide disposed on one end may be rotatably coupled to the support arm.

When a needle is inserted along the base into one of the grooves in the shaper and at least partially into the needle slide, the leverage arm can be actuated toward the base to thereby bend the needle to the desired needle bend radius. The needle bender may also include a lock plate between the base and the shaper that can be actuated toward the shaper to further secure the needle to the shaper.

A material dispense tip includes an elongated hole in an elongated neck that extends from an input end of the neck to an output end of the neck. The hole at the output end of the neck has a first diameter. The output end of the neck is positioned against a die surface. A punch is inserted into the hole at the input end of the neck. An external force is applied to the neck to cause the output end of the neck to be deformed under compression by the die surface, to reduce the diameter of the hole at the output end of the neck from the first diameter to a second diameter that is less than the first diameter.

A bio paracentesis needle includes a tube-shaped body having a hollow portion through which a suture is inserted, an insertion portion formed at an end of the body to cut skin and insert the body, and at least one removal cut to an inside of the body to remove waste under the skin when the body is inserted. The insertion portion includes a first inclined edge having a diagonal surface inclined downward in a direction from a first end of the both to the hollow portion, a second inclined edge having a diagonal surface inclined upward from a second end of the body to the first inclined edge, the second end being positioned opposite the first end, and a third inclined edge has a diagonal surface inclined downward in a direction from an end of the first inclined edge to the second inclined edge.
