Patent number: 11938317Abstract: Energy is transmitted to a body lumen or passageway in the form of pulsed electric fields (PEFs) and in a manner which provides focal therapy. In some embodiments, PEFs are delivered through independent electrically active electrodes of an energy delivery body, typically in a monopolar fashion. Such delivery concentrates the electrical energy over a smaller surface area, resulting in stronger effects than delivery through an electrode extending circumferentially around the lumen or passageway. It also forces the electrical energy to be delivered in a staged regional approach, mitigating the effect of preferential current pathways through the surrounding tissue. Focal delivery of PEFs can provide increased tissue lethality by employing precise timing and sequencing of energy delivery to the electrodes.Type: GrantFiled: December 7, 2022Date of Patent: March 26, 2024Assignee: Galvanize Therapeutics, Inc.Inventors: William Sanford Krimsky, Paul Brian Friedrichs, Roman Turovskiy, Robert E.

Publication number: 20230414270Abstract: Devices, systems and methods are provided for treating conditions of the heart, particularly the occurrence of arrhythmias, more particularly atrial fibrillation, atrial flutter, ventricular tachycardia, to name a few. The devices, systems and methods deliver therapeutic pulsed electric field energy to portions the heart to provide tissue modification, such as to the entrances to the pulmonary veins in the treatment of atrial fibrillation. Such tissue modification creates a conduction block within the tissue to prevent the transmission of aberrant electrical signals. Generally, the tissue modification systems include a specialized catheter, a high voltage waveform generator and at least one distinct energy delivery algorithm. Example embodiments of specialized catheter designs are provided and include a variety of delivery types including focal delivery, “one-shot” delivery and various possible combinations.Type: ApplicationFiled: September 7, 2023Publication date: December 28, 2023Applicant: Galvanize Therapeutics, Inc.Inventors: Isidro GANDIONCO, Kirby CHIANG, Curt Robert EYSTER

Publication number: 20230405313Abstract: Devices, systems and methods are provided for delivering molecules, particularly small molecules and/or macromolecules, to cells within the body, particularly to target cells which directly therapeutically benefit from the functionality of the molecules. Example molecules include DNA plasmids, RNAs (e.g. messenger RNA (mRNA), small interfering RNA (siRNA), micro RNA), oligonucleotides, antisense oligonucleotides (ASO), proteins and/or materials which invoke genetic or epigenetic changes in the cellular behavior, to name a few. In such instances, the molecules are driven into the target cells with the use of pulsed electric fields (PEFs) which deliver the molecules through the cell wall of the target cells so that the desired genes are able to carry out the desired effect within the cells. Thus, the molecules are to be delivered to the desired location within the body at a desired time and in a desired concentration relative to the delivery of the pulsed electric fields for optimal outcomes.Type: ApplicationFiled: February 1, 2023Publication date: December 21, 2023Applicant: Galvanize Therapeutics, Inc.Inventors: Chiara Pastori, Robert E.

Publication number: 20230172650Abstract: Devices, systems and methods are provided for delivering pulsed electric field (PEF) energy to tissue through one or more energy delivery bodies, each having one or more electrodes. The PEF energy is generated from a waveform having a variety of features. Waveform delays, such as inter-pulse delays, inter-cycle delays, inter-phase delays, inter-packet delays, inter-bundle delays, may be utilized within a treatment to obtain a desired outcome. In particular, these delays may be specifically manipulated to obtain particular desired outcomes. For example, one, some or all of these delays may be manipulated to control various aspects of PEF therapy so as to mitigate any associated risks, such as gas formation, electrical discharge, cavity formation, muscle contraction, and temperature rise, to name a few. In some embodiments, the delays distribute the period over which PEF energy is delivered, resulting in marked changes and optimization to the treatment delivery outcomes.Type: ApplicationFiled: October 7, 2022Publication date: June 8, 2023Applicant: Galvanize Therapeutics, Inc.Inventors: Quim Castellvi, Robert E.

Patent number: 11638819Abstract: Embodiments described herein relate to signal generators, systems including signal generators, and related methods. A signal generator includes capacitor(s) to store energy used to generate a treatment signal. The signal generator also includes a waveform shaping circuit, a controller, a voltage sense circuit, and a current sense circuit. The waveform shaping circuit is coupled to the capacitor(s) and includes first, second, third, and fourth switches, each of which is configured to be selectively turned ON and OFF, to allow current to pass through the switch when turned ON, and to prevent current from passing through the switch when turned OFF. The controller selectively controls the switches in order to generate the treatment signal. The controller also selectively controls the switches in order to perform certain fault tests, which rely on voltages sensed by the voltage sense circuit and currents sensed by the current sense circuit.Type: GrantFiled: April 9, 2021Date of Patent: May 2, 2023Assignee: Galvanize Therapeutics, Inc.Inventors: Timothy J.

Publication number: 20230082389Abstract: Apparatuses, systems and methods are provided for treating pulmonary tissues via delivery of energy, generally characterized by high voltage pulses, to target tissue using a pulmonary tissue modification system (e.g., an energy delivery catheter system). Example pulmonary tissues include, without limitation, the epithelium (the goblet cells, ciliated pseudostratified columnar epithelial cells, and basal cells), lamina propria, submucosa, submucosal glands, basement membrane, smooth muscle, cartilage, nerves, pathogens resident near or within the tissue, or a combination of any of these. The system may be used to treat a variety of pulmonary diseases or disorders such as or associated with COPD (e.g., chronic bronchitis, emphysema), asthma, interstitial pulmonary fibrosis, cystic fibrosis, bronchiectasis, primary ciliary dyskinesia (PCD), acute bronchitis and/or other pulmonary diseases or disorders.Type: ApplicationFiled: September 9, 2022Publication date: March 16, 2023Applicant: Galvanize Therapeutics, Inc.Inventors: Jonathan Reuben Waldstreicher, William Sanford Krimsky, Denise M.

Publication number: 20220387095Abstract: Damaged, diseased, abnormal, obstructive, cancerous or undesired neural tissue treated by delivering specialized pulsed electric field (PEF) energy to target tissue areas. In some instances, the target tissue includes a tumor, a benign tumor, a malignant tumor, a cyst, or an area of diseased tissue. Most brain and spinal cord tumors develop from glial cells. These tumors are sometimes referred to as a group called gliomas. They arise from the supporting cells of the brain, called the glia. These cells are subdivided into astrocytes, ependymal cells and oligodendroglial cells (or oligos). One difficulty in the treatment of gliomas is that they are behind the blood-brain barrier (BBB) and blood-tumor barrier (BTB) which leads to poor delivery of anti-cancer drugs or immune agents to the tumor-infiltrated brain.Type: ApplicationFiled: May 17, 2022Publication date: December 8, 2022Applicant: Galvanize Therapeutics, Inc.Inventors: Robert E.
