Subdermal medical system for generating measurement data or providing a therapy

A medical system, comprising:

• a first medical device, comprising:
• a screw body comprising a non-electrically conductive material, wherein the screw body includes a cavity, wherein a portion of the screw body is threaded, and wherein the screw body is configured to couple to a musculoskeletal system beneath a dermis;
• a screw head configured to couple the screw body, wherein the screw head seals the cavity from an external environment, wherein the screw head comprises an electrically conductive material, and wherein the screw head coupled to the screw body forms a screw;
• electronic circuitry configured to perform at least one task, wherein the screw head is configured to couple to a ground of the electronic circuitry;
• and
• a dual band antenna coupled to the electronic circuitry, wherein a first antenna of the dual band antenna is configured to operate within a first frequency band below 1 gigahertz, wherein a second antenna of the dual band antenna is configured to operate within a second frequency band above 1 gigahertz, wherein the first frequency band and the second frequency band do not overlap, wherein the electronic circuitry is non-operative until one or more radio frequency signals are received by the dual band antenna, wherein the electronic circuitry is configured to harvest energy received by the dual band antenna, wherein the electronic circuitry is enabled after a predetermined amount of energy is harvested, wherein a terminal of the dual band antenna is coupled to the screw head, and wherein the electronic circuitry and dual band antenna reside within the cavity of the screw body.

A medical system, comprising:

• a first medical device, comprising:
• an enclosure comprising a non-electrically conductive material, wherein the enclosure includes a cavity, wherein the enclosure is configured to be placed beneath a dermis;
• a cap to seal the enclosure, wherein the cap comprises an electrically conductive material;
• electronic circuitry configured to measure one or more parameters or provide a therapy, wherein a ground of the electronic circuitry is coupled to the cap;
• and
• a dual band antenna coupled to the electronic circuitry, wherein a first antenna of the dual band antenna is configured to operate within a first frequency band below 1 gigahertz, wherein a second antenna of the dual band antenna is configured to operate within a second frequency band above 1 gigahertz, wherein the electronic circuitry is non-operative until one or more radio frequency signals are received by the dual band antenna, wherein the first frequency band and the second frequency band do not overlap, wherein the electronic circuitry is configured to harvest energy received by the dual band antenna, wherein the electronic circuitry is enabled to perform at least one task after a predetermined amount of energy is harvested, wherein a terminal of the dual band antenna is coupled to the cap, and wherein the electronic circuitry and the dual band antenna reside within the cavity of the enclosure.
