Bi-SOFT: VIVACY'S new patented delivery system
In 2018, VIVACY introduces Bi-SOFT®, a next-generation patented injection delivery system that reinvents the concept of a traditional syringe. The new device has a unique design and provides greater precision, comfort and control to the physician during injection of VIVACY’s dermal fillers (such as Stylage or Desirial).
In its continuing quest for innovative excellence in medical aesthetics, VIVACY Laboratories, have developed a new- generation injection delivery system, Bi-SOFT®, to support physicians in their daily practice by providing them greater precision, comfort, and control during the injection of VIVACY’s dermal fillers.
What is Bi-SOFT® technology? The VIVACY’s main design challenge was to find a compromise between stability and maneuverability, which may be crucial for certain aesthetic applications. To achieve this, the center of gravity of the new Bi-SOFT® syringe was placed near the second edge of the piston closer to the physician’s hand to increase the stability of the syringe when the pressure on the thumb rest is strong. In addition, such positioning makes the syringe fold naturally into the palm of the physician’s hand to obtain excellent repeatability of the positioning of the syringe in their hands. This concept has been developed and patented in France.
The body of the syringe including barrel, plunger and luer tip are made of transparent medical-grade polycarbonate material. The «soft-touch» parts of the syringe, made from TPE (Thermoplastic elastomer), provide extra grip and stability between the surface and the physician’s gloves. It also reduces the injection force sensation, especially when using high-viscosity volumising HA products.
The new Bi-SOFT® syringes are ergonomically designed to be easy to use by young, as well as highly experienced users. The concave-shaped surface of the finger flange with the lifted edges helps avoid a lateral sliding of the doctor’s fingers from the gripping surface, and thereby secure the injection gesture.
The syringes are designed in five different unique colors to help quickly identify the VIVACY’s injectables: the purple for the smoothing and filling products (STYLAGE® S, STYLAGE® M and STYLAGE® L), the pink for STYLAGE® Special Lips, the green for the volumising fillers (STYLAGE® XL and STYLAGE® XXL), the blue for the mesotherapy products (STYLAGE® HydroMax) and the orange ones for DESIRIAL® range indicated for the vulvo-vaginal rejuvenation.
The surface of the plunger rod has been increased by 80% in comparison to a traditional syringe allowing the physician to operate the syringe with the palm of the hand (and not simply with the thumb) without harming the stability of the syringe. The shape of the plunger head is preferably elliptical to avoid the presence of sharp edges that can cause pain and discomfort during the injection. In addition, an increase of its gripping surface gives to the physician a greater freedom in the injection angles, making product administration easier.
The physician can perform aspiration test, if necessary, thanks to the special marks located on the surface of the grip plate. According to the VIVACY’s survey conducted on 25 physicians, 88% of them felt a great difference in handling, ease and regularity of injection, and are willing to integrate the new Bi-SOFT® system into their daily practice.
