First Claim
Patent Images
1. A medical device wearable by a subject, the device comprising:
- an implantable component having a housing and a first antenna coupled to the housing, wherein at least one of the housing or the first antenna is made of a flexible material such that the housing and the first antenna follow a curvature of a skull of the subject when implanted between the skull and a scalp of the subject, wherein the implantable component measures EEG signals representing brain activity;
an external second antenna, the second antenna having a loop portion sized to fit over a head of the subject; and
an external control module configured to interact with the implantable component via the external second antenna and receive and process the EEG signals from the implantable component.

Abstract
A wearable medical device system having an external, necklace-shaped antenna that is sized and configured for placement about the neck of a subject, and having an implantable device with an implanted antenna that communicates with the external antenna to permit the transfer of energy and data between external and implantable components. The wearable medical device includes a control module that communicates with the implanted device via the external antenna. The implantable device includes an electrode configured to provide stimulation to a nerve.
