A medical implant device includes a shaft, an expandable member coupled to the distal end portion of the shaft, a sleeve and a detachment mechanism. The expandable member is configured to move between a collapsed configuration and an expanded configuration, and can be used to deliver a medicament, a therapeutic substance and/or a structural member into the body. The sleeve is coupled to the distal end portion of the shaft, and is configured to move relative to the shaft between a first position and a second position. The sleeve is configured to be disposed about the expandable member when in the first position and disposed apart from the expandable member when in the second position. The detachment mechanism is coupled to the distal end portion of the shaft, and is configured to detach the expandable member from the shaft when the sleeve is in the second position. |
