Transducer Arrays

Electric field generator

Connection cable and box

Easy-access sleeve bag

Convertible, 5-in-1 bag

Optune is small and light weighing just 2.7 pounds. This makes Optune wearable and portable, so continuous treatment with Optune can be received almost anywhere.

The recommendation to turn Optune on at least 75% of the time (18 hours per day) gives you the flexibility to decide which times of the day are best for you. You can customize your Optune treatment plan by taking breaks during the day.

Four sterile, single-use transducer arrays are connected to the electric field generator to deliver therapy. Transducer arrays should be changed at least 2 times per week (one set of arrays should not be worn for more than 4 days at a time).

The portable field generator should be carried with you to deliver Tumor Treating Fields (TTFields) as you go about your day.

Black and white color-coded sockets on the cable box help ensure that transducer array connectors are properly connected.

Openings conveniently located at the top and bottom make it easy to reach device controls.

The convertible, 5-in-1 bag can be worn 5 different ways and has additional battery storage, making it ideal for on-the-go use.

The system offers features designed to enhance carrying comfort and usability:

  • Easy-grip texture allows for simple handling
  • Battery indicator displays power and alerts you when it’s time to change the battery
  • Light-detecting sensor auto-dims the device and the charger in the dark

Other components include:

  • Portable batteries: 4 batteries are provided with each kit; each battery lasts for 2 to 3 hours
  • Charger for portable batteries: Batteries will need to be recharged for 2 to 4 hours. The batteries can be charged and used many times over the course of 6 to 9 months
  • Plug-in power supply and power cords: “No-Stop Swap” enables you to swap batteries or power source without disrupting delivery of TTFields

Applying transducer arrays

Optune delivers therapy through 4 adhesive patches, called tranducer arrays. These arrays are applied to your scalp. They are powered through the connection cable and box, which is powered by the battery. If you or your loved one is starting treatment with Optune, applying transducer arrays will soon become a part of your routine. With the help of a caregiver, your head will be shaved and arrays changed at least 2 times per week (one set of arrays should not be worn for more than 4 days at a time).

Optune offers flexibility to help you incorporate treatment into your daily life

A large clinical study demonstrated that people who used Optune at least 75% of the time (18 hours per day) lived longer. This gives you the flexibility to decide which times of day are best for you. You can customize your Optune treatment plan by taking breaks during the day.
