Abstract
According to one aspect, an implantable medical device may include an anchor assembly configured to anchor the medical device to a body lumen. The implantable medical device may also include a capsule. The capsule may include a pH sensor. The pH sensor may be configured to measure a pH of contents within the body lumen. The capsule may also include a power source, a controller, and an impedance sensor. The impedance sensor may be configured to measure an impedance within the body lumen.
Claims20
An implantable medical device, comprising:
- an anchor assembly configured to anchor the medical device to a body lumen;
- and
- a capsule, wherein the capsule comprises:
- a pH sensor configured to measure a pH of contents within the body lumen,
- a power source,
- a controller, and
- an impedance sensor configured to measure an impedance within the body lumen.
A method for sensing within a body lumen of a patient, comprising:
- sensing a pH with an implanted medical device coupled to the body lumen;
- sensing a direction of travel of contents within the body lumen with an impedance sensor of the medical device;
- based on the sensed pH and the sensed direction of travel, determining whether the patient has experienced an event;
- and
- transmitting data from the implanted medical device to a data acquisition module located outside of a body of the patient.
A method for sensing within a body lumen of a patient, comprising:
- sensing a direction of travel of contents within the body lumen with an impedance sensor of the medical device, wherein the impedance sensor is exposed to an interior of the body lumen;
- based on the sensed direction of travel, determining whether the patient has experienced an event;
- and
- transmitting data from the implanted medical device to a data acquisition module located outside of a body of the patient when an upstream direction of travel is sensed.
