Oocyte Retrieval Needles

Kitazato OPU Needles provide a safe and efficient oocyte retrieval while minimizing trauma and pain, due to their triple cut blade, continuous aspiration flow and unique Thin Wall design.

We offer the widest range of Oocyte Retrieval Needles with single lumen (from 16G to 21G) and double lumen (from 16G to 18G).

The thinner diameters are ideal for patients with low response, natural cycles or for working without anesthesia during the ovarian puncture.

Thin Wall Design

Provides a wider inner diameter to our needles maintaining the same outer diameter.

This allows oocyte retrieval to be carried out with a smaller gauge needle and therefore reduces the possibility of bleeding and the risk of injuries to the uterine lining, whilst minimizing stress in the oocyte during aspiration.

Ergonomic handle with position marker

Provides additional control throughout the oocyte pick-up and helps to control the position of the needle blade.

Silicon bung with syringe connection

Facilitates the flushing of the needle.
