Patent number: 11801312Abstract: A method of treating cancerous tumors is presented herein. The method includes injecting an effective dose of a plasmid encoded for IL-12, B7-1 or IL-15 into a cancerous tumor and subsequently administering at least one high voltage, short duration pulse to the tumor. The electroporation pulses may be administered at least 700V/cm for a duration of less than 1 millisecond. The intratumor treatments with electroporation may be administered in at least a two-treatment protocol with the time between treatments being about 7 days. The intratumor treatments with electroporation may be administered in a three-treatment protocol with a time of four days between the first and second treatments and a time of three days between the second and third treatments. It was found that the intratumor treatments using electroporation not only resulted in tumor regression but also induced an immune memory response which prevented the formation of new tumors.Type: GrantFiled: October 5, 2020Date of Patent: October 31, 2023Assignee: University of South FloridaInventors: Richard Heller, Melinda Lee Lucas

Patent number: 11123554Abstract: A method and system for delivering a molecule to a specific area of a tissue by controlling temperature and impedance is presented. The method is generally comprised of applying heat to a biological structure, such as cells or tissues, to heat the biological structure to a preset temperature after which at least one electroporation pulse is administered to the biological structure. Impedance is measured as a feedback control mechanism after each pulse and pulse parameters are adjusted accordingly until desired impedance is reached. The system generally comprises an electroporation system capable of generating at least one pulse, measuring impedance and measuring temperature. The method may be used to deliver a molecule such as a vaccine or therapeutic to a biological structure, such as for prevention or treatment of SARS-CoV-2 infection.Type: GrantFiled: November 25, 2020Date of Patent: September 21, 2021Assignees: University of South Florida, Old Dominion UniversityInventors: Richard Heller, Loree C.

Patent number: 10881447Abstract: Systems and methods for treating or manipulating biological tissues are provided. In the systems and methods, a biological tissue is placed in contact with an array of electrodes. Electrical pulses are then applied between a bias voltage bus and a reference voltage bus of a distributor having switching elements associated with each of the electrodes. The switching elements provide a first contact position for coupling electrodes to bias voltage bus, a second contact position for coupling electrodes to the reference voltage bus, and a third contact position for isolating electrodes from the high and reference voltage buses. The switching elements are operated over various time intervals to provide the first contact position for first electrodes, a second contact position for second electrodes adjacent to the first electrodes, and a third contact position for a remainder of the electrodes adjacent to the first and second electrodes.Type: GrantFiled: November 30, 2017Date of Patent: January 5, 2021Assignee: Old Dominion University Research FoundationInventors: Karl Schoenbach, Richard Heller

Patent number: 10668278Abstract: Catheter devices can include an elongate housing extending along a major axis, the elongate housing comprising a first end an opening. The catheter devices can also include an electrode assembly disposed in the elongate housing and including deformable electrodes with respective electrode distal ends, where the electrode distal ends each consist of respective member portions and respective tip portions. The electrode assembly is slidably movable within the housing along the major axis to allow the electrode distal end portions to transition between a first retracted position and a second extended position. The catheter device is configured such that an average distance between the tip portions in the second position is configured to be greater than an average distance between the tip portions in the first position the tip portions are positioned substantially in a same plane when the electrode assembly is in the second position.Type: GrantFiled: March 24, 2015Date of Patent: June 2, 2020Assignee: Old Dominion University Research FoundationInventors: Richard Heller, Chen Yeong-Jer

Patent number: 10660693Abstract: Systems and methods for treatment of a biological tissues including target tissues and other tissues. The method includes elevating a temperature of the target tissues above a physiological temperature of the biological tissues to treatment temperature, and generating an electric field extending through at least a portion of the target tissues using a pre-defined sequence of short voltage pulses applied between at least two electrodes.
