Abstract: An extractable device is used to insert a flowable material into a vertebral body. The device comprises a filling member and a flowable material. The filling member is made of a flexible wall which includes a holding portion and an injection port via which the flowable material is injected into the holding portion after insertion into the vertebral body. The holding portion is provided with an opening which is releasably closed by a closure device so as to make the opening substantially resistant to the passage of material there through. Once the flowable material in the holding portion increases in viscosity, the closure device is released, thereby enabling the filling member to be extracted from the vertebral body so as to leave only the material in the vertebral body. The flowable material should be a material capable of setting to a hardened condition.

Abstract: 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.
