Abstract: Systems and methods are disclosed for measuring a femoral alignment of a femur of a patient via a surgically implanted measurement device. An exemplary method may include: receiving, via at least one processor, first data from the measurement device, wherein: a housing of the measurement device is coupled to a musculoskeletal system of a patient; and the first data includes a plurality of measurements from each of an accelerometer and a gyroscope included with an inertial measurement unit disposed within the housing; determining the femoral alignment based on the first data; and causing a display to output the determined femoral alignment.

Abstract: A wirelessly powered medical implant system comprising: a power source system including: an automatic gain controller to receive input power, automatically adjust the input power based on a feedback signal with an offset phase delay, and provide the adjusted input power as output power; a source resonator to generate, based on the output power, a magnetic field to transmit wireless power via the magnetic field, and provide the feedback signal; and an offset phase delay circuit to receive the feedback signal from the source resonator, generate the offset phase delay, and include the offset phase delay with the feedback signal; and a medical implant including: an implant resonator to receive the transmitted wireless power via the magnetic field; and one or more sensors, wherein the feedback signal is based on inductive coupling of the magnetic field between the source resonator and the implant resonator.
