Wearable sleeve shrinks cancer therapy machines to pocket size

Researchers at the University of Waterloo have developed a portable, wearable compression sleeve designed to replace bulky, expensive post-cancer swelling therapy machines. This new device, roughly the size and weight of a smartphone, integrates a pump, valves, and a microfluidic chip to provide controlled, targeted compression through lightweight inflatable chambers embedded in the sleeve. Unlike traditional systems that require patients to remain seated and tethered to large control boxes costing up to $3,000, the wearable sleeve operates on a rechargeable battery lasting up to eight hours, allowing users to move freely during therapy and improving overall usability and patient experience. The technology leverages microfluidics to precisely control pressure and airflow in a compact form, maintaining therapeutic effectiveness while significantly reducing size and cost. The research team, collaborating with clinicians and therapists, is conducting early patient testing to refine comfort and ease of use. With multiple patents secured and ongoing efforts toward regulatory approval and commercialization, the project aims to deliver effective, affordable therapy at roughly half the cost of current
