BioSig Allowed Additional Foundational U.S. Patent for its PURE EP System

BioSig Technologies Inc. announced that the U.S. Patent Office has allowed another foundational patent, including additional 29 patent claims covering its PURE EP System. The patent application number 16/271,466 entitled “Systems and Methods for Signal Acquisition and Visualization,” was filed on May 9, 2018, and subject to an accelerated Track One patent application filed on Feb. 8, 2019.

The allowed claims provide even broader patent coverage for the company’s PURE EP System and address the overall system architecture for filtering biomedical signals during a medical procedure such as an ablation procedure in frequency ranges of interest to the practitioner. The allowed claims address the novel system architecture related to a unique amplifier topology for conditioning cardiac (e.g., ECG and intra-cardiac) and other physiologic signals, specifically to clearly define and record low-amplitude, frequency-specific information, which may be acquired during ablation and other large-signal perturbations, such as pacing. This ensures the acquisition of multiple low amplitude cardiac signals in the presence of numerous sources of electrical noise and environmental interference aside from the large signals injected during ablation and pacing.
 
“We are pleased the US Patent Office continues to quickly recognize the novelty of our advanced PURE EP System and to receive further patent protection for our proprietary technology. BioSig continues to expand its intellectual property estate with three recent patent allowances including this one, and we are pleased to add this additional patent to our growing intellectual property portfolio covering our PURE EP System,” stated Kenneth L. Londoner, founder, chairman and CEO of BioSig Technologies Inc.
 
The PURE EP System is indicated as a computerized system intended for acquiring, digitizing, amplifying, filtering, measuring and calculating, displaying, recording and storing of electrocardiographic and intracardiac signals for patients undergoing electrophysiology (EP) procedures in an EP laboratory under the supervision of licensed healthcare practitioners who are responsible for interpreting the data.

BioSig Technologies is a medical technology company developing a proprietary biomedical signal processing platform designed to improve the electrophysiology (EP) marketplace. Led by a management team and a veteran Board of Directors, BioSig Technologies is preparing to commercialize its PURE EP System. The technology has been developed to address an unmet need in a large and growing market.
 
The company’s first product, PURE EP System, is a computerized system intended for acquiring, digitizing, amplifying, filtering, measuring and calculating, displaying, recording and storing of electrocardiographic and intracardiac signals for patients undergoing electrophysiology (EP) procedures in an EP laboratory. The system is indicated for use under the supervision of licensed healthcare practitioners who are responsible for interpreting the data. This cardiac signal acquisition and display system is engineered to assist electrophysiologists in clinical decision-making during electrophysiology procedures in patients with abnormal heart rates and rhythms. BioSig’s ultimate goal is to deliver technology to improve upon catheter ablation treatments for the prevalent and potentially deadly arrhythmias, atrial fibrillation and ventricular tachycardia. BioSig has partnered with Minnetronix on technology development and received U.S. Food and Drug Administration 510(k) clearance for the PURE EP System in August 2018.
