Certain examples of the disclosure concern an implantable sensor. The implantable sensor includes a sensor assembly configured to connect to a suture. The sensor assembly also includes a substrate and a resonant circuit coupled to the substrate. The resonant circuit is configured to electrically resonate at a resonant frequency when exposed to a first electromagnetic field and to emit a second remotely detectable electromagnetic field. The substrate is configured to deform in response to a tensile force applied by the suture and to change a resonant parameter of the resonant circuit in response to the deformation.

The present invention is directed to an implantable medical device, comprising: a device body, with at least a portion of said body coated by a sensing coating that comprises an echogenic material or a radiopaque material, or combinations thereof, said sensing coating configured to dissolve or swell in presence of at least one infection biomarker; wherein a portion of said sensing coating is covered by a protective film, forming a protected portion, said protected portion configured not to dissolve or swell in presence of said biomarker and methods of detecting presence of biomarkers in the vicinity of an implanted medical device.

The present disclosure relates to a linear flexible electrode for a peripheral nerve and a manufacturing method thereof. A linear flexible electrode for a peripheral nerve is provided, wherein the flexible electrode includes an implantation portion and a fixing portion, wherein at least part of the implantation portion is implantable into a peripheral nerve bundle, and the fixing portion is configured to fix the flexible electrode to the peripheral nerve bundle or other tissues in the vicinity of the peripheral nerve bundle, wherein: the flexible electrode includes a first insulation layer, a second insulation layer and a wire layer between the first insulation layer and the second insulation layer; and the implantation portion includes one or more electrode sites, each electrode site is electrically coupled to one of the wires in the wire layer, and in contact with the peripheral nerve after the flexible electrode is implanted into the peripheral nerve bundle to collect electrical signals from the peripheral nerve and transmit the collected electrical signals through the wires, or apply received electrical signals through the wires to the peripheral nerve.

A method for monitoring a cardiovascular pressure in a patient includes measuring, by pressure sensing circuitry of an implantable pressure sensing device, the cardiovascular pressure of the patient. The method further includes transmitting, via wireless communication circuitry of the implantable pressure sensing device, the measured cardiovascular pressure to another device. The method further includes determining, by processing circuitry of the other device, whether a posture of the patient at a time of the measured cardiovascular pressure was a target posture for cardiovascular pressure measurements. The method further includes determining, by the processing circuitry of the other device, whether to store or discard the transmitted cardiovascular pressure based on determining whether the posture was the target posture.
