Patent number: 11918481Abstract: The present invention provides expandable devices and insertion tools for deploying the expandable devices. The expandable devices are capable of increasing in height and width when expanded from a closed configuration to an open configuration to occupy a larger volume and to present a larger surface area. The expandable devices are lockable and are capable of rigidly occupying a space after expansion. In some embodiments, the expandable devices are useful as interbody devices for spinal fusions.Type: GrantFiled: April 8, 2021Date of Patent: March 5, 2024Assignee: MUSC Foundation for Research DevelopmentInventors: Stephen Kalhorn, Mark E. Semler, Joseph Ruscito, Christopher Hapstack

Patent number: 11813131Abstract: A declogging assembly (20) is configured for use with a suction conduit (10). The suction conduit has a head (14) at a first end (15) and a vacuum tube connection (16) at a second end (17). The assembly includes a body (30). The body defines a first aperture (32), a second aperture (34), and a third aperture (36). The assembly also includes a plug (40) disposed within the body (30). The plug has a surface (42) configured to contact the head (14) of the suction conduit (10) so as to move the plug from a first position, in which the first aperture (32) is in fluid communication with the second aperture (34), to a second position, in which the first aperture (32) is in fluid communication with the third aperture (36). The assembly (20) also includes a biasing member (50) configured to bias the plug into the first position.Type: GrantFiled: August 24, 2021Date of Patent: November 14, 2023Assignee: MUSC Foundation for Research DevelopmentInventors: Stephen P.
