Abstract
Systems, methods, and dressings for providing reduced pressure to a tissue site on a patient are presented that involve wirelessly providing power to a reduced-pressure pump. In one instance, a RFID antenna is used to power a reduced-pressure pump that is fluidly coupled by a conduit to a reduced-pressure dressing. In another instance, a reduced-pressure dressing incorporates a micro-pump and a RFID antenna that is used to power the micro-pump. Other systems, methods, and devices are presented.
