Apparatuses and methods for percutaneously implanting objects, such as radioactive seeds or markers, in patients. In one embodiment, a device for percutaneously implanting an object in a patient includes a handle, a cannula projecting outwardly from the handle, and an actuator movably disposed relative to the handle. In one aspect of this embodiment, the cannula can be configured to releasably hold the object and percutaneously penetrate the patient. In another aspect of this embodiment, the actuator can be operably connected to the cannula and operable to move the cannula relative to the handle and release the object within the patient. In a further aspect of this embodiment, the cannula can include a tip portion having a restriction configured to releasably hold the object for implantation in the patient.
