Abstract

An apparatus, a system, and a method for monitoring and/or performing a diagnosis. A first implantable device measures a property of a first tissue in a body and includes a housing. The housing includes a first processing circuitry for causing the first implantable device to measure the property of the first tissue. A second implantable device for measures a property of a second tissue in the body and includes a housing. The housing includes a second processing circuitry for causing the second implantable device to measure the property of the second tissue using at least one sensor. The second implantable device is communicatively coupled to the first implantable device and provides information about the measured property of the second tissue to at least one of the following: the first implantable device and at least one processing device disposed externally to the body.

Claims

1. An apparatus for monitoring and/or performing a diagnosis, comprising

a first implantable device for measuring a property of a first tissue in a body and having a housing, the housing including:

a first processing circuitry for causing the first implantable device to measure the property of the first tissue using at least one of the following;

an RF measurement of the property of the first tissue or an analysis of a signal reflected from the first tissue, wherein the signal is transmitted by the first implantable device toward the first tissue;

a second implantable device for measuring a property of a second tissue in the body and having a housing, the housing including a second processing circuitry for causing the second implantable device to measure the property of the second tissue using at least one sensor;

the second implantable device is communicatively coupled to the first implantable device and provides information about the measured property of the second tissue to at least one of the following;

the first implantable device and at least one processing device disposed externally to the body.

2. The apparatus according to claim 1, wherein the first implantable device includes a power source for powering the first implantable device.

3. The apparatus according to claim 2, wherein the first implantable device transmits energy to the second implantable device to power the second implantable device.

4. The apparatus according to claim 1, wherein the property of the first tissue is at least one of:

a level of hydration of the first tissue, a dielectric property of the first tissue, and an radio frequency (“

RF”

) measurement of the first tissue, and wherein the property of the second tissue is blood pressure.

5. The apparatus according to claim 1, wherein the first implantable device includes an antenna selected from a group consisting of:

a dipole antenna, a wire loops antenna, a stent-based antenna, and a printed antenna.

6. The apparatus according to claim 1, wherein the first implantable device wirelessly communicates with the second implantable device.

7. The apparatus according to claim 1, wherein the first implantable device is connected with the second implantable device using a wire.

8. The apparatus according to claim 1, wherein the housing of the first implantable device contains the second implantable device, wherein a power source of the first implantable device powers the second implantable device.

9. The apparatus according to claim 1, wherein the second implantable device is selected from a group consisting of:

pulmonary artery blood pressure sensor and a left atrium pressure sensor.

10. The apparatus according to claim 1, wherein the housings of the first and second implantable devices are manufactured from a biocompatible material.

11. The apparatus according to claim 1, wherein the second implantable device reflects at least one signal transmitted by the first implantable device, wherein the first implantable device receives the reflected signal.

12. The apparatus according to claim 11, wherein the second implantable device modulates the signal prior to reflecting the signal transmitted by the first implantable device.
