Abstract:

A device for implanting an object into animal tissue and a method for using the same device is provided. The device includes a cannula having a longitudinal axis, a passageway extending therethrough, a proximal end, and an opposite distal end that is insertable into tissue and defines an exit aperture for discharge of the object from the cannula. The device also includes an axially movable plunger disposed and oriented in a non-coaxial relationship within at least a portion of the cannula and a partial barrier disposed within the cannula adjacent to its distal end and configured to at least partially block the passageway, where the partial barrier at least partially defining an object receiving opening that is in communication with the passageway and sufficiently sized to receive the object and the plunger. When the device is in a first position, the partial barrier prevents the object from entering the passageway even when the plunger is inserted into the object receiving opening. When the device is moved to a second position, the passageway is aligned with the object, such that, upon movement of the plunger towards the distal end of the cannula, the plunger engages the object and pushes it through the object receiving opening towards and through the exit aperture.
