Dual-lumen oocyte aspiration needle

机译:双腔卵母细胞抽吸针

摘要

A dual-lumen oocyte collection device is described. The device is unique in that it includes parallel cannulas which extend axially outward from a proximal end of a hub. The device is also unique in that it further includes a finger depression on the hub. This depression located on the hub directly corresponds to an elongated beveled point of a cannula that extends from a distal end of the hub. The unique parallel cannulas and the finger depression allow medical personnel to evenly rotate and accurately orientate the beveled tip of the device to puncture a follicle on an ovary with minimal trauma prior to collecting an oocyte.
