Publication number: 20230414276Abstract: A method and a pulsed electric field (PEF) ablation instrument are provided. According to one aspect, a method in a PFA generator includes receiving electrical responses for each of at least one non-therapeutic waveform. The process also includes determining an electric field distribution based at least in part on the received electrical responses. The process further includes selecting a non-therapeutic waveform that produces an electric field distribution that satisfies criteria. The process also includes mapping the selected non-therapeutic waveform to an ablative waveform.Type: ApplicationFiled: June 21, 2023Publication date: December 28, 2023Inventors: Timothy G.

Publication number: 20230310871Abstract: Implantable medical device including a pulsed-voltage generator and one or more implantable electrical leads. In one example, the implantable medical device supports the defibrillator and ablation modalities characterized by different respective sets of waveform parameters, such as the pulse amplitude and width. In some examples, the implantable medical device also supports a pacing modality. The electrodes used for the different modalities are variously selected from a plurality of electrodes located in distal portions of the implantable electrical leads and on the exterior surface of the implantable device box. An electronic controller of the implantable medical device is wirelessly programmable to appropriately control, e.g., in a patient-specific manner, operations of the pulsed-voltage generator and transitions between different modalities.Type: ApplicationFiled: April 3, 2023Publication date: October 5, 2023Inventors: Brian T.

Patent number: 8774915Abstract: Capacitor packaging according to the disclosure provides advantages particularly in connection to compact and/or complex-shaped medical devices (e.g., having limited interior volume defined by domed and/or irregular exterior surfaces). In addition, capacitors of the type shown and described herein can be utilized in relatively compact external defibrillators, such as automatic external defibrillators or clinician-grade, automated or manually-operated external defibrillators. In one form a plurality of capacitors having substantially flat exterior surfaces are placed in an abutting relationship between at least a pair of major surfaces and the major surfaces are spaced from an opposing or adjacent surface in a non-parallel configuration. In other forms, one or more exterior surface portions have a common and/or complex radius dimension (i.e., the surfaces are curved).Type: GrantFiled: December 23, 2010Date of Patent: July 8, 2014Assignee: Medtronic, Inc.Inventors: Craig L. Schmidt, William L. Johnson, Steven Joseph May, Christian S. Nielsen, John Daniel Norton, Anthony W. Rorvick, Jeffrey A. Swanson, William K. Wenger

Patent number: 8086312Abstract: The invention is directed to designs for capacitors of implantable medical devices (IMDs) such as implantable defibrillators, implantable cardioverter-defibrillators, implantable pacemaker-cardioverter-defibrillators, and the like. The capacitor designs can reduce capacitor volume significantly and may also improve charge holding capacity relative to conventional capacitor designs. Moreover, since capacitors typically comprise a significant portion of the volume of an IMD, significant reductions in capacitor volume can likewise significantly reduce the size of the IMD.Type: GrantFiled: May 28, 2009Date of Patent: December 27, 2011Assignee: Medtronic, Inc.Inventors: Christian S.
