Systems and methods for monitoring health conditions

A patient treatment system for treating heart failure in a patient, the system comprising:

• a shunt having a lumen extending therethrough, wherein, when the shunt is implanted in the patient, the lumen is configured to fluidly couple a left atrium and a right atrium of the patient;
• a sensor implantable into the patient and in communication with the shunt, wherein the sensor is configured to measure one or more parameters;
• an external component configured to be worn or otherwise adhered to the patient;
• and
• an implantable relay device operably coupled to the sensor and the external component, wherein the implantable relay device is configured to (i) receive a first signal from the external component and transmit a second signal corresponding to the first signal to the sensor, and (ii) receive a third signal from the sensor and transmit a fourth signal corresponding to the third signal to the external component.

A patient monitoring system, comprising:

• an implantable device, wherein the implantable device includes—
• an implantable portion sized and configured to be implanted within a patient, the implantable portion including a sensor configured to measure one or more physiological parameters, and
• a surface portion coupled to the implantable portion and configured to be adhered to a surface of the patient;
• and
• a wearable device configured to engage the surface portion to communicate with the implantable portion.

A system for monitoring patient status, the system comprising:

• an external component configured for placement on a patient's skin, wherein the external component includes a first sensor component;
• and
• an implantable component configured for placement beneath a dermal layer of skin, wherein the implantable component includes a second sensor component,
• wherein the first and second sensor components are configured to measure a physiological parameter indicative of an amount of fluid in the tissue.
