Successful aspiration starts here

A successful follicle aspiration needs to be fast, precise and retrieve the maximal amount of undamaged oocytes without complications. It is a critical procedure involving a lot of anxiety for the patient, which also needs to be taken care of.

Sense aspiration needle

Reduced needle tip without compromising aspiration time, control and oocyte safety.

The best of both worlds

Sense has a thin, 20 G, needle tip and a thicker, 17 G, needle body.

The unique design of Sense makes it an ideal needle to work with. It has the control and precision you need with optimal aspiration time. With Sense you keep the benefits of working with a conventional needle and gain the advantages of a thin needle.

Unique design

The reduced tip gives you the advantages of a small sized needle. As only the tip is reduced, the rigidity and flow are maintained, ensuring accurate guidance while helping to maximise the number of oocytes collected.

Proven performance

A prospective, randomised study by Wikland et al. found that oocyte retrieval performed with the Sense needle resulted in a greater number of patients with less than expected vaginal bleeding compared to a conventional 17 G needle. Further findings were that the use of Sense also resulted in a significantly reduced overall pain experience – 19% lower compared to a conventional needle. Regardless of needle size, there were no statistical differences in aspiration time, oocyte recovery and fertilisation rate.

Innovative echo marking for perfect control

The new echo marking is achieved through innovative laser etching to give you the high visibility you need during oocyte retrieval.

Sharpness in every move

During the development of the new echo marking, we also further refined the way we grind the needles. The result is an even sharper tip that enables a smooth penetration of the tissue1.

Colour coded labels

All needle labels are colour coded to simplify identification of needle types.

Double sterile pack

To meet surgical standards, each needle is individually packaged in a double sterile barrier to avoid contamination.

Around since the beginning, used worldwide

Together with the pioneers in IVF, Vitrolife invented the transvaginal follicle aspiration needle with an ultrasound probe already in the 1980s. This technique has since then been used successfully worldwide.
