Abstract: Disclosed herein joint implants with sensors and methods for activating sensors in joint implants. A joint implant according to the present disclosure can include a first implant on a first bone and a second implant on a second bone of a joint. The first implant can include a magnet. The second implant can include one or more sensors, a processor, a battery, and a switch. The switch can couple the battery to the processor to power the processor and the one or more sensors when the switch detects a magnetic field strength.

Abstract: A medical sensor is disclosed for mounting within a medical device. In one embodiment, more than one medical sensor is mounted to a printed circuit board using surface mount technology to accurately place the medical sensors in predetermined positions. The medical sensor is a sensor for measuring a force, pressure, or load. The medical sensor is manufactured in a process that supports consistency, matching, reliability, and performance. The medical sensor comprises a substrate, a dielectric layer overlying the substrate, and four strain gauges overlying the dielectric layer. Interconnect and pads are formed overlying the dielectric layer. The interconnect couples the four strain gauges into a full bridge Poisson gauge and couples the pads to the full bridge Poisson gauge. The active strain gauges are placed in a predetermined location on the substrate that support measurement of a force, pressure, or load applied to the substrate.

Abstract: Disclosed herein are joint implants with sensors and methods for manufacturing joint implants with sensors. A knee joint implant according to the present disclosure may include a femoral implant, a tibial implant and a tibial insert disposed therebetween. The tibial implant may include a medial side with a medial central region defined around a medial center, a lateral side with a lateral central region defined around a lateral center and a central region disposed between the medial central region and the lateral central region. At least one sensor and a battery may be disposed within the tibial insert. The medial central region and the lateral central region may be defined by solid volumes extending from a proximal surface to a distal surface of the tibial insert.

Abstract: Disclosed herein are joint implants and methods for tracking joint implant performance. A joint implant according to the present disclosure can include a first implant on a first bone and a second implant on a second bone of a joint. The first implant can include medial and lateral markers. The second implant can include a medial marker reader to identify the medial markers and a lateral marker reader to identify the lateral markers to provide positional data of the first implant with respect to the second implant. The second implant can include a medial load sensor to measure medial load data and a lateral load sensor to measure lateral load data. A processor coupled to the medial marker reader, the lateral marker reader, the medial load sensor, and the lateral load sensor can transmit the positional data, the medial and lateral load data to an external source.
