Yes! The Undervests supports all LVAD systems.
Wearing the Freedom Undervest may help reduce the risk of driveline infections by:

  • Immobilizing the driveline at the wound site: minimizing movement at the exit site which reduces trauma to the soft tissue.
  • Evenly distributes the weight of the external LVAD equipment without applying tension to the driveline.
The driveline and LVAD equipment is carried comfortably next to the body under the clothing. The driveline is never exposed while wearing the Undervest properly, so there is a much reduced likelihood for snagging or other types of damage to occur to it. When worn properly, the dedicated pockets securely hold the controller and batteries. The larger Kangaroo pouch that houses the pockets will catch the equipment even if in the unlikely event that it inadvertently falls out of the pocket.
The Undervest is made of a 83% Polyester, 17% Lycra blend that offers 4-way stretch and supple compression.
Yes! Machine wash in cold water only. It is a good idea to fasten the Velcro fasteners before washing to preserve their integrity.
Yes! For the HeartMate II and III LVADS, leaving the system controller in its pocket, switch from your batteries to your patient cable as you do normally, while wearing the Undervest. There are gaps in the Velcro fastener on both sides of the Kangaroo pouch where the cable can easily be passed through, depending upon which side you sleep on. Fasten the Undervest closed and enjoy your rest without the VAD bag. For Heartware LVADS, leave both the controller and one of your batteries in their designated pocket (or anywhere in the larger Kangaroo pouch that is comfortable). Replace and remove the other battery with the charging cable as you would normally do. Pass the charging cable through either of the gaps in the Velcro fastener and rest easier.
We offer the Undervest in four sizes: small, medium, large and , X-large. Because the stretch characteristics of the Undervest have to be considered, we advise that you purchase the Undervest one full shirt size SMALLER than you normally wear.
The X-Large may accommodate sizes up to 3XL in most cases, depending upon your build
No. The controller pocket is lined with an insulating material that actually reflect heat away from your body. While in its pocket, you should feel no heat from the controller.
No. Since your LVAD equipment will be nestled in their pockets and the driveline secured beneath the Undervest, there is no fear of tugging or pulling at the exit site.
Checking your controller or replacing your batteries is easily done by opening up the kangaroo pouch. There are tabs (top and bottom) in the front and on either side, to easily pull the Velcro fastener apart. You can simply look down and check your controller parameters (Heartware) or lift it out of its pocket to view the LED screen (HeartMate II and III). To replace the batteries, unfasten the Velcro on the side where the battery rests, lift it out and switch it as usual, then place the new battery in to the side pocket. Refasten the Velcro by lining up the top and bottom tabs on the front and on each side of the Undervest, for a neat closure.
Not yet. Though the fabric is available in other colors, black is the only other color most customers are interested in. The price for this fabric in black is almost double! We are committed to keeping the Undervest affordable. Being an undergarment, you will need to have more than one, so we want to keep the cost of the Undervest low. We are negotiating with the supplier for better pricing.
All of Medi-Materials products are made in the USA!

    I love my shirt and just ordered another one. It’s well made and securely holds my equipment. The only reason I didn’t give it 5 stars is because of the controller section. I have a Heartware VAD and the cables all come out on the sides. The Velcro on the driveline side needs to be stretched across both cables. I’d like it more if the Velcro closure was two parts, one for driveline and one for battery.

      Hello Elizabeth,

      We really like your idea! The HeartWare controller is a bit awkward in that it has cables coming out from two sides. The Velcro fasteners were meant to hold the controller in place until the larger kangaroo pouch was secured. We think your idea can be implemented in a near future version of the Undervest.

      Thank you!

      Hello Elizabeth,

      We just wanted you to know that we are working on implementing your idea. When the prototype is complete we would like you to test it for us.

    Do you have sizes larger than xl? I would need to order 3x

    • John


      Our XL fits people from 2X through 3x and some 4x, depending upon body type.

    How well does the vest work for Heartmate 3?

    when are you expecting more mediums? I normally wear a large shirt as I am a small framed person. Would a large be to loose?

    • John


      The Undervest works perfectly with the HeartMate 3. The manufacturer we use to make our LVAD shirt is extremely busy during this time of year, something we did not know to anticipate. We were told that the lead time would be a minimum of 8+ weeks. Coupled with the fact that this is our first year in this market and that the Undervest has been in very high demand, we were caught unaware. Our large MAY fit you depending upon your body type. Give it a try. You can just return it if the fit isn’t perfect.

    My husband wears an XL in shirts so we ordered the Large. He holds all his weight in his belly and thinks it’s way too tight but, is giving it some time to stretch. Will most likely order another one soon. Would like other colors as well. Thanks!

    • John

      Hello Mrs. Burns,

      Perhaps the XL will be a better fit for your husband. It shouldn’t be overly tight. We want the Undervest to be comfortably snug, but not tight. We will be offering the Undervest in black, soon.
