Publication number: 20240076622Abstract: Methods provided by the present disclosure utilize extracorporeal shockwaves, mechanical impacts and/or principles of lithotripsy to break up a tissue sample into smaller fragments—clusters of cells and/or single cells—after which a desired cellular fraction can be isolated from the sample. Devices provided by the present disclosure deploy focused and/or directed shockwaves, and/or focused and directed mechanical impacts, to break apart a tissue sample. The devices maintain the sample in a sterile, closed environment during exposure to the shockwaves or mechanical impacts. Therefore, the shockwaves and/or mechanical impacts are generated outside of a closed device and are transmitted through one or more walls of the device into its interior, where the sample is located.Type: ApplicationFiled: November 13, 2023Publication date: March 7, 2024Inventors: John Chi, Ben-Chen Chi
