Conducted communication in a medical device system
First Claim
1. An implantable medical device for implantation into a patient, comprising:
- a housing;
a pulse generation circuit disposed at least partially within the housing;
a plurality of electrodes electrically coupled to the pulse generation circuit, the plurality of electrodes being exposed external to the housing; and
a controller operatively coupled to the pulse generation circuit, the controller configured to;
command the pulse generation circuit to deliver a sub-threshold phasic conducted communication pulse via at least two of the plurality of electrodes;
wherein the sub-threshold phasic conducted communication pulse comprises a first phase having a first polarity followed by a second phase having an opposite second polarity;
the second phase having a duration of less than 60 microseconds; and
the first phase having a duration of between five percent and eighty percent of the duration of the second phase.

Abstract
An implantable medical device for implantation into a patient may include a housing, a pulse generation circuit disposed at least partially within the housing, a plurality of electrodes electrically coupled to the pulse generation circuit, the plurality of electrodes being exposed external to the housing, and a controller operatively coupled to the pulse generation circuit. The controller may be configured to command the pulse generation circuit to deliver a phasic conducted communication pulse via at least two of the plurality of electrodes. Additionally, the phasic conducted communication pulse may comprise a first phase having a first polarity followed by a second phase having an opposite second polarity, wherein the second phase may have a duration of less than 60 microseconds, and wherein the first phase having may have a duration of between five percent and eighty percent of the duration of the second phase.
