There are over 2 million amputees in the US and 12 million in the world, with about 185,000 more amputations occurring every year. Residual limbs, or the “stump” that is left after amputation, cause prosthesis users discomfort for many reasons. There are issues of discomfort from the prosthetic socket, phantom limb pain, and poor circulation. The end result is deep irritation in the remaining part of the limb.

We have created a solution that not only relieves the discomfort that amputees experience, but also vastly improves the quality of life for amputees. The Costello Heat Sleeve slides over the socket of the prosthesis in which the residual limb is placed, supplying a much-needed flow of heat to the “stump.” It does so without inserting any wiring between the stump and the prosthetic socket, so as to keep the wiring from causing any further injury to the stump through friction and pressure, greatly enhancing the quality of life for amputees.

The device was invented by an amputee, Bryan Costello, to relieve his own suffering. Bryan, a pipefitter by trade, soon realized that his invention could benefit many other amputees. His hope is to make the Heat Sleeve available worldwide in 2018.
