  • Researchers at Stanford have invented a device that can be advanced, placed, detached and implanted into one or more body lumens or cavities to perform internal diagnostic or therapeutic functions. In one embodiment of the invention, the device can be used for continuous monitoring and/or recording of a person’s physiological signals (e.g. heart rate, cardiac electrical activity, heart sounds). This invention also provides a delivery portion that enables the advancing of the entire device through one or more body lumens and/or cavities. Furthermore, the invention provides a user-controlled mechanism for detaching a portion of the device from the entire device structure such that the detached portion of the device can be placed and implanted within a body lumen or cavity. It also provides a user-controlled mechanism for deactivating the detached portion of the device after it has been implanted for a given duration. The invention can communicate with an external device that can download, process, and store the sensed information from the device and transmit the data to a remote healthcare provider or user.
