STEINER-TAN Needle 19gauge


STEINER-TAN Needle 19gauge: for normal IVF or IVM.
Preferred by many colleagues, because there is a need only for minimal sedation and analgetics or even no sedation.

STEINER-TAN Needle is a unique Needle Technology starting double lumen 7 cm prox. of needle tip outside of needle. At this position 2 drilled holes bring a communication with flushing fluid in plastic tubing surrounding needle.


1.) 1 lumen guarantees optimal turbulences during aspiration and flushing as well.

2.) at least 3 fold shorter aspiration and flushing time in comparison with DL Needles.

3.) This technique enables flushing needles down to 21gauge.

4.) Optimizing number of eggs/ follicle is the way towards milder IVF reducing Gonadotrophins.
