This disclosure relates to an intraoperative guidance system. The guidance system comprises: an X-ray imaging device to create a two-dimensional digital image of a joint and an implant component; and a computer system configured to: store an initial three-dimensional model of the joint and the implant component; receive two or more two-dimensional digital images of the joint and the implant component; create a digital three-dimensional model of the joint and the implant component based on the two or more two-dimensional digital images; perform registration between the digital three-dimensional model and the initial three-dimensional model to determine a placement of the implant component; determine an intraoperative simulated performance metric by simulating movement of the digital three-dimensional model based on the placement; and provide an indication to a surgeon of the intraoperative simulated performance metric as an assessment of a current placement of the implant component.

A system may include an ultrasound probe and a controller unit configured to obtain a baseline ultrasound image of a patient's breast area using the ultrasound probe and to obtain a follow-up ultrasound image of the patient's breast area using the ultrasound probe. The controller unit may further be configured to use one or more machine learning models to compare the baseline ultrasound image with the follow-up ultrasound image; detect a change in a morphology or integrity of the patient's breast area based on the comparison of the baseline ultrasound image with the follow-up ultrasound image; and generate a recommendation for a medical intervention based on the detected change.

Monitor device of a personal care system, devices of a personal care system, including primary accessory device and secondary accessory device, and related methods are disclosed. The monitor device comprises a processor; a memory connected to the processor; a first interface connected to the processor, the first interface configured for connecting the monitor device to the personal care appliance; and a second interface comprising a transceiver module connected to the processor and configured for connecting the monitor device to the primary accessory device and the secondary accessory device, wherein the monitor device is configured to: establish a primary connection between the monitor device and the primary accessory device; transmit primary monitor data to the primary accessory device via the primary connection; determine whether a first primary connection criterion based on a quality of the primary connection is satisfied; and in accordance with a determination that the first primary connection criterion is not satisfied, transmit secondary monitor data to the secondary accessory device.

The present disclosure provides an accessory device of an ostomy system and related methods including a method, performed in an accessory device, for monitoring an ostomy system comprising a monitor device and an ostomy appliance comprising a base plate configured to be placed on a skin surface of a user, wherein the accessory device comprises an interface configured to communicate with at least the monitor device of the ostomy system, the method comprising obtaining monitor data from the monitor device, the monitor data being indicative of a condition of the ostomy system; determining, based on the monitor data, an operating state of the ostomy system in a first time period after a first event; in accordance with the operating state of the first time period being a first primary operating state, communicating a first primary indication via the interface; determining, based on the monitor data, an operating state of the ostomy system in a second time period after the first time period; and in accordance with the operating state of the second time period being the first primary operating state, communicating a second indication different from the first primary indication via the interface.

In one aspect, an electronic device for promoting proper use of a walking aid during lower extremity injury rehabilitation comprises at least one load sensor configured to measure a load on the walking aid. A memory stores rehabilitation program data defining at least one time interval of a rehabilitation period and, for each time interval, a target load for the walking aid during the time interval. A currently operative time interval of the at least one time interval of the rehabilitation period is identified. Data is received, from the load sensor(s), indicative of a dynamic load on the walking aid during a patient step. Based upon the received data, a peak load upon the walking aid during the patient step is determined. A user notification indicating that the peak load is non-compliant with the target load for the walking aid for the currently operative time interval is provided.

Disclosed herein are systems and methods for sensor systems. In one embodiment, a system may include an implantable component and an external component. The implantable component may comprise a housing and an electrode array configured to receive a plurality of biopotential signals. The housing may comprise a wireless power receiver and a wireless data transmitter to transmit representations of the biopotential signals. The external component may comprise a wireless data receiver configured to receive the plurality of digital representations of the biopotential signals and a wireless power transmitter configured to provide power to the internal component. A shielding component may separate the wireless power transmitter from the wireless data receiver. An interface may be configured to communicate with a prosthesis and configured to cause the prosthesis to implement a voluntary motion based on the plurality of digital presentations of the biopotential signals.

The present disclosure provides alert implants that comprise a medical device and an implantable reporting processor (IRP), where one example of such a medical device includes a component for a total knee arthroplasty (TKA) such as a tibial extension, a femoral component for hip replacements, a breast implant, a distal rod for arm or leg breakage repair, a scoliosis rod, a dynamic hip screw, a spinal interbody spacer, and tooling and methods that may be used to form the alert implant, and uses of such alert implants in the health maintenance of patients who receive the implant.

The present disclosure provides methods of identifying a loosened joint implant by analyzing acoustic emissions from the implant. The present disclosure further provides apparatuses for measuring acoustic data and analyzing acoustic emissions from a joint implant.

The application is directed to devices and methods where one or more magnetic or magnetizable implants provides therapeutic benefits to a patient. The implant may be useful for expanding the range of motion of joints or dynamically providing different responses to changing conditions in the body where the implant is placed. An electromagnet is placed on or in a bone on one side of a joint, and another electromagnet or magnetically active material is placed on or in a bone on the opposing side of the joint. The electromagnet may be continuously energized to relieve pressure in the joint space, or may, be energized in response to forces applied to the joint.
