Publication number: 20230256252Abstract: A method of selecting a combination of electrodes for use in neurostimulation includes testing combinations of electrodes in an electrode array to identify an atrial capture. The atrial capture is indicated by at least one effect on an atrium. The method includes excluding electrodes with the atrial capture to result in remaining electrodes of the electrode array, testing combinations of the remaining electrodes of the electrode array for effect on cardiac contractility and/or relaxation, and selecting a combination of electrodes from the remaining electrodes. The selected combination has both a desired effect on cardiac contractility and/or relaxation and does not have an undesired side effect.Type: ApplicationFiled: June 11, 2021Publication date: August 17, 2023Inventors: Michael Scott Brandner, Alan David Eskuri, Steven D.

Publication number: 20200101292Abstract: A method of facilitating therapeutic neuromodulation of a heart of a patient includes positioning an electrode in a pulmonary artery, positioning a sensor in vasculature, delivering via a stimulation system first and second electrical signals of a series of electrical signals to the electrode. The second electrical signal differs from the first electrical signal by a magnitude of a first parameter of a plurality of parameters. The method includes determining, via the sensor, sensor data indicative of one or more heart activity properties in response to the delivery of the series of electrical signals, and delivering a therapeutic neuromodulation signal to the pulmonary artery using selected electrical parameters. The selected electrical parameters include a selected magnitude of the first parameter. The selected magnitude of the first parameter is based at least partially on the sensor data. The therapeutic neuromodulation signal increases heart contractility.Type: ApplicationFiled: December 2, 2019Publication date: April 2, 2020Inventors: Steven L. Waldhauser, Steven D. Goedeke

Patent number: 10485435Abstract: In one example, this disclosure is directed to a kit for intravascular implantation of an implantable medical device, the kit comprising an outer sheath, the outer sheath sized to traverse a vasculature of the patient, and an elongated inner sheath with a tapered distal end. The inner sheath is slidable within the inner lumen of the outer sheath and is selectably removable from the inner lumen of the outer sheath by sliding the inner sheath out of the proximal opening of the outer sheath. The kit includes an elongated deployment receptacle including a deployment bay slidable within the inner lumen of the outer sheath when the inner sheath is not within the inner lumen of the outer sheath. The deployment bay carries an implantable medical device through the inner lumen of the outer sheath and facilitates deployment of the implantable medical device from the distal end of the outer sheath.Type: GrantFiled: May 29, 2012Date of Patent: November 26, 2019Assignee: Medtronic, Inc.Inventors: Erik C.
