Abstract

A subcutaneously implantable device includes a housing, a first prong, and a second prong. A first electrode on the first prong is configured to contact the first lung. A second electrode on the device is configured to contact the first lung or a second lung. A third electrode on the second prong is configured to contact the heart or the tissue surrounding the heart. Sensing circuitry in the housing in electrical communication with the first electrode, the second electrode, and the third electrode is configured to measure an impedance in the first lung and/or the second lung, and/or a transthoracic impedance across the first lung and the second lung through the first electrode and the second electrode, and to measure an electrical signal from the heart through the third electrode.

Claims30

Dependent claims

A subcutaneously implantable device comprising:

a housing;
a first prong with a proximal end attached to the housing and a distal end extending away from the housing that is configured to contact a first lung;
a first electrode on the first prong that is configured to contact the first lung;
a second electrode on the device that is configured to contact the first lung or a second lung;
a second prong with a proximal end attached to the housing and a distal end extending away from the housing that is configured to contact a heart or a tissue surrounding the heart;
a third electrode on the second prong that is configured to contact the heart or the tissue surrounding the heart;
and
sensing circuitry in the housing in electrical communication with the first electrode, the second electrode, and the third electrode that is configured to measure an impedance in the first lung and/or the second lung, and/or a transthoracic impedance across the first lung and the second lung through the first electrode and the second electrode, and to measure an electrical signal from the heart through the third electrode.

5 more elements

A method of measuring an impedance in a first lung and/or a second lung, and/or a transthoracic impedance across the first lung and the second lung, and an electrical signal from a heart using a subcutaneously implantable device, the method comprising:

transmitting a current from a first electrode positioned on a distal end of a first prong of the device to a second electrode on the device, wherein the first electrode is in contact with the first lung, and wherein the second electrode is in contact with the first lung and/or the second lung;
measuring an impedance between the first electrode and the second electrode using sensing circuitry in a housing of the device to determine the impedance of the first lung and/or the second lung, and/or the transthoracic impedance across the first lung and the second lung;
and
sensing an electrical signal from a heart through a third electrode on a distal end of a second prong of the device using the sensing circuitry in the housing, wherein the third electrode is in contact with the heart and/or a tissue surrounding the heart.
