发明名称 Tri-fluted vascular access needle
摘要 A needle disclosed herein may include an elongate body extending between a proximal end and a distal end with a central longitudinal axis defined by the body, where the distal end includes a single sharp point along the central longitudinal axis and defining a distal end terminus three longitudinal fluted surfaces converging at the distal end terminus; and three longitudinal beveled cutting edges defining borders between the fluted surfaces and converging at the distal end terminus. Needle embodiments may include one or more ports open into and/or proximal of the fluted surfaces and communicating with one or more longitudinal needle lumens.

主权项 1. A vascular access needle, comprising: an elongate body extending between a proximal end and a distal end; and a central longitudinal axis defined by the body; where the distal end includes: as single sharp point along the central longitudinal axis and defining a distal end terminus;three longitudinal fluted surfaces converging at the distal end terminus;three longitudinal beveled cutting edges defining borders between the fluted surfaces and converging at the distal end terminus; where the three longitudinal beveled cutting edges are all symmetrical to each other; andat least a first port open from at least a first of the three longitudinal fluted surfaces to a first needle lumen.
