Patent number: 11806073Abstract: Systems, devices, and methods for transvascular ablation of target tissue. The devices and methods may, in some examples, be used for splanchnic nerve ablation to increase splanchnic venous blood capacitance to treat at least one of heart failure and hypertension. For example, the devices disclosed herein may be advanced endovascularly to a target vessel in the region of a thoracic splanchnic nerve (TSN), such as a greater splanchnic nerve (GSN) or a TSN nerve root. Also disclosed are methods of treating heart failure, such as HFpEF, by endovascularly ablating a thoracic splanchnic nerve to increase venous capacitance and reduce pulmonary blood pressure.Type: GrantFiled: October 22, 2021Date of Patent: November 7, 2023Assignee: Axon Therapies, Inc.Inventors: Anisha Bapna, Zoar Jacob Engelman, Howard Levin, Pajhand Iranitalab, Casey Andrew Miller, Thomas Ryan McGrath, Manuel Arzadon Javier, Jr.

Patent number: 9233250Abstract: Embodiments of the present invention concern the timing of sending one or more commands to control circuitry of a multi-electrode lead (MEL). In one embodiment, the one or more commands are sent to control circuitry within the MEL during a predetermined portion of a cardiac pacing cycle to avoid potential problems of prior systems that were not synchronized with the cardiac pacing cycle. In one embodiment, the one or more commands are sent when cardiac tissue is refractory from a cardiac pacing pulse, to prevent the command(s) from potentially undesirably stimulating cardiac tissue. The command sending can occur such that the one or more commands are sent between instances when sensing circuitry of the implantable cardiac stimulation device is being used to obtain one or more signals indicative of cardiac electrical activity, to prevent interference between the one or more commands with the signals indicative of cardiac electrical activity that are sensed.Type: GrantFiled: December 29, 2009Date of Patent: January 12, 2016Assignee: Pacesetter, Inc.Inventors: Anne Shelchuk, Yongjian Wu, Chris Pontiga, April Pixley, Pajhand Iranitalab, Elisabeth M.

Patent number: 7751886Abstract: An implantable stimulation device that maps the location of irritable foci causing an atrial arrhythmia is provided by certain embodiments disclosed herein. The device may, for example, collect intra-cardiac data from a plurality of electrodes spatially distributed throughout a chamber of the heart. This data may be compared with data related to the location of each electrode and the electrical properties of the heart to approximate a point of origin for the atrial arrhythmia. Further embodiments may provide methods and systems for using this information to provide more efficient treatment of the atrial arrhythmia. For example, an optimized ATP pulse train may be determined based on the location of one or more irritable foci. Such an ATP pulse train may be applied to more efficiently terminate the atrial arrhythmia.Type: GrantFiled: July 16, 2007Date of Patent: July 6, 2010Assignee: Pacesetter, Inc.Inventor: Pajhand Iranitalab
