  • Patent number: 10856881
    Abstract: In various embodiments, a system for delivering an implantable device inside a body cavity includes: 1) a core cannula; 2) an access sheath; 3) an injection apparatus for filling the implantable device with one or more fluids; and 4) expanding members operatively connected to the core cannula for preventing the core cannula from advancing through a body orifice once the core cannula and expanding members exist the access sheath. According to particular embodiments, a distal end of the core cannula is pre-attached to the implantable device through a device locking member. In one or more embodiments, upon assessment, an injection apparatus is removed using an injection apparatus handle, the implantable device is detached from the core cannula via a device deployment handle (to be implanted), and the access sheath is removed.
