IMPLANTABLE MEDICAL DEVICE CROSSTALK EVALUATION AND MITIGATION
First Claim
Patent Images
1. A method comprising:
- determining a characteristic of a first electrical signal sensed by a first implantable medical device (IMD) while a second IMD delivers a second electrical signal to a tissue site within a patient, wherein the first and second IMDs are implanted within the patient;
determining an electrical noise status based on the characteristic of the first electrical signal; and
generating a notification based the noise status.

Abstract
Electrical crosstalk between two implantable medical devices or two different therapy modules of a common implantable medical device may be evaluated, and, in some examples, mitigated. In some examples, one of the implantable medical devices or therapy modules delivers electrical stimulation to a nonmyocardial tissue site or a nonvascular cardiac tissue site, and the other implantable medical device or therapy module delivers cardiac rhythm management therapy to a heart of the patient.

21. A system comprising:
-
a first implantable medical device (IMD) that senses a first electrical signal within a patient; a second IMD that delivers a second electrical signal to a patient, wherein the first IMD senses the first electrical signal while the second IMD delivers the second electrical signal to the patient; and a processor that determines a characteristic of the first electrical signal, determines an electrical noise status based on the characteristic of the first electrical signal, and generates a notification based the noise status. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38)

39. A computer-readable medium comprising instructions that cause a programmable processor to:
-
determine a characteristic of a first electrical signal sensed by a first implantable medical device (IMD) while a second IMD is delivering a second electrical signal to a tissue site within a patient, wherein the first and second IMDs are implanted within the patient; determine an electrical noise status based on the characteristic of the first electrical signal; and generate a notification based the noise status. - View Dependent Claims (40, 41)

42. A method comprising evaluating crosstalk between a first implantable medical device (IMD) implanted within a patient and a second IMD implanted within the patient with an external device, wherein the external device:
-
determines a characteristic of a first electrical signal sensed by the first IMD while a second IMD delivers a second electrical signal to a tissue site within a patient; determines an electrical noise status based on the characteristic of the first electrical signal; and generates a notification based the noise status.
