Sense™ Single and Double Lumen

Optimise oocyte retrieval performance and improve patient comfort

Description

Oocyte retrieval needle

Purpose

Intended for flushing and/or aspiration of oocytes from ovarian follicles.

Storage

Store in +2 to +30°C

SENSE NEEDLE

Sense the difference

Precision and performance in every retrieval

The Sense needle gives you the best of two worlds. The reduced tip in combination with the larger sized body work together in a unique way for the oocyte, the patient and you. You get uncompromised performance and improved patient comfort1-5.

The Sense needle offers unique performance with its reduced tip for less bleeding and pain, and a larger body for better control and precision1-5. The features of the Sense needle provides ideal conditions for oocyte retrieval as only the tip is reduced. Rigidity and flow are maintained, ensuring accurate guidance to collect the oocytes. With Sense you’ll keep the benefits of working with a conventional needle and gain the advantages of working with a thin needle.

SENSE NEEDLE

Single or double? The choice is yours

There are two types of Sense needles: single lumen and double lumen. That means you can choose the needle that best suits your handling preferences while still ensuring high quality and performance.

YOUR CHOICE

Two options.
One trusted performance.

Choose between single lumen and double lumen based on your handling preferences.

→
OPTION 01

Sense single lumen

The cross-section surface area of the Sense single lumen needle tip is 59% less than a conventional 17G needle tip. As only the tip is reduced, rigidity and flow are maintained, ensuring accurate guidance while helping to maximise the number of oocytes collected.

Sense combines the benefits of a conventional needle with the advantages of a thin one.

OPTION 02

Sense double lumen

Sense double lumen is based on the tried and trusted Sense single lumen needle, which features a reduced tip for less bleeding and pain and a larger body for optimal precision and retrieval time.

Sense double lumen has the same reduced tip and larger body, while also adding the option of easy follicle flushing during pick up. The cross-section surface area of the Sense needle tip is 56% less than a conventional 17G needle tip.

Designed for uncompromised control

Echomarking for perfect control

Created through innovative laser etching, giving you the high visibility you need during oocyte retrieval.

 

Ultra-sharp design

For low penetration resistance and high precision. The needle tip is providing extraordinary sharpness, high precision and the utmost safety. The bevel grinding ensures low resistance penetration, while distinctive backpoint grinding prevents deviation.

The Sense needle is easy to handle

It is safe and convenient in your hands. The bevel mark on the handle indicates the needle position, while the soft tube and bent cannula prevent kinking and oocyte damage.

Colour coded peel-off labels

All needle labels are colour coded to simplify identification of needle type. The peel-off labels facilitate patient journal handling. 

Double sterile pack to meet surgical standards

Each needle is individually packaged in a double sterile barrier to avoid contamination in the operating theatre.

Reduced needle tip

Reduced needle tip for less bleeding and pain, larger sized body for optimal control, precision and retrieval time.

The Sense family just got bigger

A single Sense needle with 16.5 G body and a tip of 19 G for optimal control and precision

The trusted Sense family just got a new member – a single lumen needle with the same concept you know – a reduced tip. The needle with a reduced tip combines uncompromised oocyte recovery and aspiration time with optimised comfort. Our new single lumen Sense needle has a 16.5 G body and a tip of 19 G, which makes it optimal for control and precision, while still reducing bleeding and pain1, 2, 3, 4.

CLINICAL RESULTS

It makes sense, and results prove it

The Sense needle gives you the best of two worlds. The results of two clinical studies demonstrate that the reduced tip in combination with the larger sized body work together in a unique way for the oocyte, the patient and you. You get improved patient comfort with uncompromised performance.1,4.

01 CLINICAL STUDY

30% less pain
according to Buisman et al.

2020 saw a randomised controlled trial involving 95 patients, the objective of which was to study pain in women undergoing oocyte retrieval with a reduced needle (20/17 G) compared to a standard needle (16 G)4. It concluded that the use of a thinner needle results in significantly lower (and clinically relevant) pain scores during oocyte retrieval.

Using single Sense, patients experienced 30% less pain, compared to the group using a standard needle. Patients in the reduced needle group requested significantly less analgesia during oocyte retrieval than patients in the standard needle group. Pain scores remained significantly lower up to until 2 days after the procedure.

This study was performed using the Sense Single Lumen needle
02 CLINICAL STUDY

Significantly less bleeding and pain according to Wikland et al.

To prove the benefits of the unique design of Sense, a prospective, randomised, multi-centre study was carried out in 20101.

The results were clear. Oocyte retrieval performed with the single Sense needle resulted in significantly less vaginal bleeding compared to a conventional needle. Using the Sense needle also resulted in a significantly reduced overall pain experience – 19% lower compared to a conventional needle. Most importantly, there were no differences in the number of oocytes with intact zona pellucida after aspiration, regardless of needle size.

The unique design of Sense provides ideal conditions for optimised oocyte retrieval performance and aspiration time as well as improved patient comfort.

CLINICAL EXPERIENCE

What clinicians say about Sense

Hear directly from clinicians about their experience using Sense needles.

“

I find using the Sense needle means less pain for the patient. Sense causes less trauma to the ovaries (which in turn reduces the possibility of postoperative bleeding).

The Sense needle also reduces the level of sedation needed. - in selected cases using the Sense I have not needed sedation at all.

“

My first choice is Sense single and double needles and the reason is simple, Sense needles are best for patients and have minimal side effects. There is less bleeding and less pain when using the Sense needles. I have no doubt that Sense needles, both single and double, are the best available today.

The only thing is that the doctor must use a special technique at OPU and the technique of learning how to use the Sense needles is very easy if doctors want to use it.

I use Sense for all patients and recognize its value for both my patients and myself. The clear view of the needle tip enables my control of the procedure at all times, whilst the thinner tip hasn’t altered the timing for each egg collection.

I've also seen much less bleeding and pain in my patients when using Sense, which is clearly positive for all involved!

How to create optimal conditions during oocyte retrieval

Dr. Westlander, MD, PhD, is the Medical Director at Fertilitetscentrum, a private clinic in Sweden performing around 1500 IVF cycles annually. Watch a short movie where he share his experiences in how to create optimal conditions during the oocyte retrieval procedure, both for the patient and the clinician.

Lot-to-lot consistency is secured by adhering to rigorous validated specifications and protocols. The quality of each lot is certified by a signed protocol to guarantee traceability. All stages of production are controlled, from raw materials to final product.

MEA tested

To detect toxic materials, Vitrolife has developed a highly sensitive 1-cell mouse embryo assay (MEA) that follows the development of single-cell mouse embryos to hatching blastocysts. This assay is far more sensitive than the widely used 2-cell MEA.
