Abstract
An implanter comprising a housing, a hollow needle connected to the housing, a drive pin positioned within the housing and aligned with the hollow needle, and a trigger assembly operably connected to both the housing and the drive pin. The drive pin has a distal end, and further has a retracted position wherein the distal end of the drive pin is in the housing and an extended position wherein the distal end of the drive pin portion extends out of the housing. A pellet is positioned between the needle and the distal end of the drive pin when the drive pin is in the retracted position. The drive pin expels the pellet through the hollow needle when moving from the retracted position to the extended position. The trigger assembly includes a trigger that has a relaxed position and an actuated position. The drive pin moves from the retracted position to the extended position when the trigger moves from the relaxed position to the actuated position. The invention further relates to a method for implanting an object beneath a membrane, comprising the steps of: positioning an object to be implanted between a drive pin and a hollow needle; positioning a plug between the object and the drive …
