Implant device

Claim 1

An implant device comprising: a. a tubular member having a central longitudinal axial bore therethrough, a pointed elongated annular concavely bevelled implanting end, and a charging end, each of said ends communicating with said bore; b. a plunger having a solid, pointed, elongated annular concavely bevelled end, said plunger being removeably inserted in said bore and slideably movable therein along the longitudinal axis of said tubular member from a first position to a second position at which maximum insertion of the plunger into the bore is obtained and the implanting end of the tubular member and the pointed end of the plunger are aligned to form a complimentary substantially continuous pointed elongated annular concavely bevelled penetration surface; and c. means for aligning said implanting end and said pointed end, said means for aligning being only one semicircular projection on the charging end of the tubular member, said first projection extending for a distance in the axial direction whereby a pill receiving trough is formed for facilitating introduction of an implant dosage form into the bore of the tubular member, and a second semi-circular projection on the plunger, the first and second projections being complimentary and alignable at only the second position, alignment of the first and second projections serving to simultaneously align said implanting end and said pointed end, said first projection being an extension of the charging end and having a first shoulder and a second shoulder, said plunger having a head portion the diameter of which is larger than the diameter of bore of the tubular member, said second projection being an extension of the head portion of the plunger and having a third shoulder and a fourth shoulder, said plunger being movable within said bore from the first position to the second position only when the first and second shoulders are aligned opposed to and in sliding contact respectively with the third and fourth shoulders.
