Abstract
An apparatus is provided for a non-invasive medical intervention for a user with reduced cardiac output. The medical device includes at least one electrical coil and power control circuitry. The power control circuitry is configured to provide an electrical output supplied to the at least one electrical coil at a voltage and frequency selected to drive current through the at least one electrical coil to generate a time varying magnetic field having a frequency and an intensity that triggers a response that activates a skeletal muscle to increase a venous return of blood and a lymphatic return of interstitial fluid to improve a resting cardiac output of the user.

An apparatus configured for a non-invasive medical intervention for a user with reduced cardiac output, the medical device comprising:
- at least one electrical coil;
- and
- power control circuitry configured to provide an electrical output supplied to the at least one electrical coil at a voltage and frequency selected to drive current through the at least one electrical coil to generate a time varying magnetic field having a frequency and an intensity that triggers a response that activates a skeletal muscle to increase a venous return of blood and a lymphatic return of interstitial fluid to improve a resting cardiac output of the user,
- wherein the frequency of the time varying magnetic field includes a range of 2-16 KHz, and
- wherein a flux density of the time varying magnetic field includes a range of 2-8 Gauss peak.

The apparatus of claim 7, further comprising timing circuitry configured to control the output of the power control circuitry to generate the time varying magnetic field at a duty cycle of 30%-50%.
-14. (canceled)
A method of improving cardiac output with an apparatus including at least one electrical coil, the method comprising:
- positioning the at least one electrical coil adjacent a treatment area of a user, the treatment area focused on a frontal plantar region of a foot of the user, the treatment area including a plantar nerve located in the treatment area;
- orienting the at least one electrical coil to locate a time varying magnetic field produced with the at least one electrical coil in a direction perpendicular to the plantar nerve;
- and
- operating the apparatus to generate the time varying magnetic field at a frequency and an intensity to trigger a response that activates a soleus muscle to increase a venous return of blood and a lymphatic return of interstitial fluid to improve a resting cardiac output of the user.
A method of improving cardiac output with an apparatus including at least one electrical coil, the method comprising:
- a) positioning the at least one electrical coil adjacent a surface of a treatment area of a user, the treatment area including a targeted nerve;
- b) orienting the at least one electrical coil to locate a time varying magnetic field produced with the at least one electrical coil in a direction perpendicular to the targeted nerve;
- and
- c) operating the apparatus to generate the time varying magnetic field at a frequency in a range of 2-16 KHz and a flux density of 2-8 Gauss peak to trigger a response that activates a skeletal muscle to increase a venous return of blood and a lymphatic return of interstitial fluid to improve a resting cardiac output of the user.
A method of treating an individual for a medical condition resulting, at least in part, from a reduced cardiac output, the method comprising:
- applying a time varying magnetic field to a treatment area located in the individual's foot, the treatment area focused on a frontal plantar region including a plantar nerve in the individual's foot, the time varying magnetic field oriented in a direction perpendicular to the plantar nerve;
- and
- selecting each of a frequency of the time varying magnetic field, a flux density of the time varying magnetic field, a period for application of the time varying magnetic field, and a duty cycle for the application of the time varying magnetic field to trigger a response that activates a soleus muscle to increase a venous return of blood and a lymphatic return of blood to improve a resting cardiac output of the user.
