Everstill™ Technology: Active Vibration Cancellation Platform for Safe Micromanipulation

Introduction

Contemporary technology and equipment, originally designed in the late 1970s, have given way to more sophisticated methods and more flourishing protocols. In vitro fertilization, popularly known as IVF, is a unique kind of assisted reproductive technology (ART).

Challenge

When embryos and oocytes are subjected to ART, they should not experience any vibration as they can be easily damaged. Fertility procedures like preimplantation genetic diagnosis (PGD) and preimplantation genetic screening (PGS), and sophisticated IVF methods namely, assisted hatching (AHA) and intracytoplasmic sperm injection (ICSI), need accurate movements and an environment free from vibrations.

Discussion

Syracuse, New York-based CNY Fertility Center, situated about ½ miles from the Interstate, was affected by vibrations in the building. These vibrations would also have been caused by numerous laboratory instruments like purging gas flow meters and benchtop incubators that were placed in close proximity.

Ambient building vibration and foot traffic around and within the laboratory could have been other potential sources of vibrations. However, irrespective of the source, all vibrations present potential risk for disruption and damage in the ART laboratory.

Nevertheless, safe micromanipulation techniques can be practiced by using active vibration cancellation and thus, ensure a successful procedure.

Solution: TMC Everstill™ K-400

The Everstill K-400 is designed to offer excellent vibration cancellation, thereby enabling a safe micromanipulation environment (Figure 1). Aggressive low frequency vibration isolation combined with a steady surface for the Olympus IX71 microscope was provided by the serial type active vibration control technology (Figure 2). Installation is also made relatively easy, and the system can be self-leveled simply at the press of a button.

Advantages of TMC Everstill™ K-400

In the ICSI video, vibrations in the environment can be clearly seen in the oocyte image. A successful procedure cannot be executed even when low-amplitude vibration is present.

Such vibrations can arise from the floor and through the laboratory table. When the Everstill K-400 unit was switched on after 35s, the vibration was fully eliminated and the process continued. The Olympus IX71 microscope, supported by the Everstill K-400 unit, now allows the clinic to carry out all micromanipulation methods in a safer and more efficient manner (Figure 3).

Benefits of the Everstill K-400 are as follows:

  • Low frequency vibration cancellation
  • Simple operation
  • Easy installation
  • Hard mount design
  • Automatic leveling
  • Air is not needed
