Patent number: 11866732Abstract: 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: GrantFiled: March 17, 2017Date of Patent: January 9, 2024Assignee: Synova Life Sciences, Inc.Inventors: John Chi, Ben-Chen Chi

Patent number: 11813161Abstract: A mechanical prosthetic heart valve having a ring, multiple hinges, and multiple leaflets. The hinges are attached to the ring and are evenly spaced from one another along the inner circumference of the ring. Each leaflet is rotably attached to a hinge by an opening located in the center of the lower portion of the leaflets. The ring can include multiple protrusions located along the inner circumference of the ring. The protrusions of the ring limit the opening angle of the leaflets. By limiting the opening angle of the leaflets, wear and tear of the hinges and leaflets, as well as the probability of malfunction of the mechanical prosthetic heart valve are reduced. In addition, limiting the opening angle of the leaflets may increase the opening and closing speed of the leaflets, thus improving performance of the mechanical prosthetic heart valve when the patient is experiencing an elevated cardiac frequency.Type: GrantFiled: December 30, 2021Date of Patent: November 14, 2023Assignee: CLOVER LIFE SCIENCES INC.Inventors: Osvaldo N.
