David Nghiem - Shoreview MN, US
Joshua K. Francis - East Bethel MN, US
Paul T. Simonette - Maple Lake MN, US
Garry L. Dublin - Maple Grove MN, US
Randy R. Sazenski - Robbinsdale MN, US

Assignee:

Medtronic, Inc. - Minneapolis MN

International Classification:

A61N 1/00

US Classification:

607 60, 607 32

Abstract:

A telemetry component according to an embodiment of the invention, such as a programmer or a monitor for an implantable medical device (“IMD”), includes at least one radio frequency (“RF”) antenna that is configured to accommodate far-field telemetry between the telemetry component and the IMD. The RF antenna is shaped, sized, positioned, and otherwise configured to account for surface current cancellation caused by induced surface current on an electrically conductive surface of the telemetry component.

International Classification:

A61N001/00

US Classification:

607/116000

Abstract:

A medical lead adapter assembly is provided for facilitating an electrical connection between an implantable medical lead connector and an external medical device. The adapter includes a housing, having a sidewall and a longitudinally extending connector receptacle, and at least one contact opening passing through the sidewall to the receptacle. The contact opening is positioned in a location corresponding with at least one ring contact of the lead connector, when the lead connector is engaged within the receptacle, and allows electrical connection between at least one contact element of the external medical device and the at least one ring contact of the lead connector.

Assignee:

Medtronic, Inc.

International Classification:

A61N001/00

US Classification:

607/116000

Abstract:

An adaptor facilitating electrical connection between an implantable medical lead connector and an external medical device includes a longitudinally extending connector receptacle formed by a first and second housing portion flexibly joined together. An inner surface of the connector receptacle is opened, to facilitate insertion of the connector therein, by means of a first lever arm extending laterally from the first housing portion and a second lever arm extending laterally from the second housing portion. An electrical contact formed within the inner surface of the connector receptacle is adapted to electrically engage at least one ring contact of the connector when the connector is fully inserted within the connector receptacle. An external contact surface, formed upon the first lever arm and electrically coupled to the electrical contact via a conductive pathway, is adapted for coupling with a contact element of the external medical device.

International Classification:

A61B 5/00
A61B 5/36

Abstract:

A system for accounting for adverse pacing artifacts may include an electrode apparatus and a computing apparatus. The electrode apparatus may include one or more external electrodes to monitor electrical activity from tissue of a patient. The computing apparatus may include one or more processors and may be operatively coupled to the electrode apparatus. The computing apparatus may be configured to monitor electrical activity from the tissue of the patient using the one or more external electrodes. Such electrical activity may be used to generate one or more cardiac signals of the patient over time. The computing apparatus may detect a pacing artifact in the one or more cardiac signals and determine whether to account for, and account for, the pacing artifact based on a pacing artifact characteristic of the pacing artifact when producing electrical heterogeneity information.
