    The patent rights in these inventions have been assigned to the 
Government of the United States of America. The prospective exclusive 
patent license territory may be worldwide and in a field of use limited 
to catheter-based intramyocardial ablation, for treating ventricular 
arrhythmia in a human.
    This patent license covers two patent estates as shown above, 
namely the invention described in the E-017-2024 estate, and the 
invention described in the E-061-2022 estate. ``Intramural substrates'' 
are the crux of the clinical challenge addressed by the subject patent 
estates and the proposed field of use. Specifically, these intramural 
substrates are the electrically conducting and hard-to-reach 
arrhythmogenic tissue located within the depth of the myocardial wall--
the mid-myocardium--rather than on the endocardial (inner) or 
epicardial (outer) surfaces. The inventions being exclusively licensed 
herein provide a catheter-based system and method to access these 
intramyocardium tissues, and a synchronous circumferential 
intramyocardial resynchronization and pacing (SCIRP) system intended to 
improve cardiac resynchronization therapy. Both of these inventions 
together provide a new and improved device, system and method to enable 
electrophysiologists to access and treat arrhythmogenic intramural 
substrates located within the ventricular myocardial wall, which 
currently is not systematized.
    The invention described in E-017-2024, for which we have 3 
provisional applications, 3 PCT applications, a pending U.S. national 
stage application and a pending European national stage application, 
covers a catheter-based system and method for performing ablation 
directly within the intramyocardium and particularly targeting 
ventricular tachycardia that is otherwise difficult to reach using 
existing ablation devices and methods. The system, referred to as 
VINTAGE (Ventricular Intramyocardial Navigation for Tachycardia 
Ablation Guided by Electrograms), principally uses a small flexible 
ablation microcatheter that tracks coaxially over a steerable, 
electrically insulated guidewire. Proximal to the catheter tip are 
mapping electrodes and a conductive ablation electrodes with 
perforations that can elute irrigants directly into the surrounding 
myocardial tissue. The physician navigates to the desired deep target 
using fluoroscopy, ultrasound, electroanatomic mapping and/or 
electrogram-based depth navigation (EDEN); once the ablation electrode 
reaches the target, irrigant is delivered through its openings and 
radiofrequency energy applied while irrigation continues, producing a 
controlled lesion in the abnormal tissue responsible for the 
arrhythmia. The irrigant may be an electrolyte acting to alter the 
electrical and/or physicochemical characteristics of the target 
myocardial substrate (such as increasing ionic conductivity), act as a 
thermo-conductive ``virtual ablation electrode'', or may alternatively 
be a caustic agent intended to effect adjunctive chemoablation.
    The invention described in E-061-2022, for which we have a PCT 
application, a pending U.S. national stage application, a pending 
Isreali national stage application and a pending European application, 
covers a synchronous circumferential intramyocardial resynchronization 
and pacing (SCIRP) system intended to improve cardiac resynchronization 
therapy by placing a flexible, multi-electrode pacing lead inside the 
ventricular myocardium rather than on an endocardial or epicardial 
surface. The lead contains multiple small ring electrodes and is 
implanted along a curved trajectory that can extend at least 180 
degrees--and potentially substantially around the circumference--of the 
left ventricle, including through the interventricular septum near the 
His bundle or left bundle branch. Of particular import is the ability 
to introduce these electrodes into the ventricular intramural spaces 
through a navigated guidewire introduced through the myocardium using 
electrograms or pace mapping, and leaving the electrode-bearing lead 
embedded in the heart muscle. A multichannel pulse generator then 
energizes selected myocardium implanted electrodes in unipolar or 
bipolar configurations directly stimulate ventricular muscle and, where 
appropriately positioned, the native His/LBB conduction system. In 
essence, instead of trying to resynchronize the ventricle from a few 
conventional surface pacing sites, the invention creates an 
intramyocardial array of pacing sites distributed around the ventricle, 
intended to re homogenize synchronization.
    This notice is made in accordance with 35 U.S.C. 209 and 37 CFR 
part 404. The prospective exclusive patent license will be royalty 
bearing and may be granted unless within thirty (30) days from the date 
of this published notice, the NHLBI receives written evidence and 
argument that establishes that the grant of the license would not be 
consistent with the requirements of 35 U.S.C. 209 and 37 CFR part 404.
    Complete applications for a license in the prospective field of use 
that are timely filed in response to this notice will be treated as 
objections to the grant of the contemplated exclusive patent license. 
Comments and objections submitted to this notice will not be made 
available for public inspection and, to the extent permitted by law, 
will not be released under the Freedom of Information Act, 5 U.S.C. 
552.
