Implant apparatus

Claim 3

The apparatus of claim 1 wherein said carriage exhibits a recess in its front part, which recess is adapted to receive and retain a flanged, detachable needle having a passageway extending the length of said needle.

Claim 4

The apparatus of claim 2 wherein received and retained in said carriage recess is a flanged needle having a barrel with a beveled, sharp end and an enlarged, flanged end; a passageway extending the length of said needle; and at least one pharmaceutically acceptable, implantable pellet in said needle passageway so that when said carriage is propelled rearwardly said rod extends beyond said sharp end of said needle.

Claim 5

The apparatus of claim 3 wherein a plurality of spherical, implantable pellets are in said needle passageway.

Claim 6

The apparatus of claim 3 wherein a flexible finger extends across the front part of said needle passageway to retain said pellet in said passageway.

Claim 7

The apparatus of claim 3 wherein the composition of said needle is nylon and glass particles.

Claim 8

The apparatus of claim 3 wherein said needle is plastic but has a metal tip to aid in penetrating said animal's skin.

Claim 9

The apparatus of claim 1 wherein said propelling means is a helical spring coil which is compressed when said carriage is in the cocked position and which expands when said trigger is actuated to propel said carriage rearwardly.

Claim 10

The apparatus of claim 1 wherein a portion of a metal rod is attached to the front end of said track, the unattached end of said metal rod being sufficiently sharp to penetrate said animal's skin.

Claim 11

The apparatus of claim 3 wherein a portion of a metal rod is attached to the front end of said track, the unattached end of said metal rod being sufficiently sharp to penetrate said animals skin, said metal rod being of substantially the same outside diameter as said needle and being at least as long as the portion of said needle extending beyond the front part of said track.

Claim 12

A process for subcutaneously implanting at least one biologically acceptable pellet in an animal using an apparatus including handle means for grasping said apparatus with one hand; a track attached to said handle means and having front and rear portions, said track being suitable for a carriage to move therealong; a carriage placed within said track and movable therealong with front and rear portions corresponding to the front and rear portions of said track, said carriage having (i) a recess in the front part of said carriage which is adapted to receive and retain a detachable needle having a passageway extending longitudinally through said needle, (ii) a flanged needle received and retained in said carriage recess, said needle having a barrel with a beveled, sharp end and an enlarged, flanged end, a passageway extending the length of said needle, and at least one pharmaceutically acceptable, implantable pellet in said needle passageway, (iii) passageway extending the length of said carriage parallel to the length of said track and corresponding to said needle passageway, and (iv) means to guide and stabilize said carriage along said track; propelling means to propel said carriage along said track from the front part to the rear part of said track; means attached to the rear part of said track to stop said carriage when propelled rearwardly; means attached to the front part of said track to retain said carriage; a straight, retractable rod attached to said stopping means so that the rod extends straight through said carriage passageway; means to retain said rod stationary or allow said rod to be retracted; a finger actuatable trigger attached to said handle which is designed to retain said carriage in a cocked position at the front part of said track and when actuated allows said carriage to be propelled rearwardly along said track and rod by force of said propelling means, which process comprises subcutaneously inserting said beveled, sharp end of said needle in said animal while said carriage is in the cocked position, forcing said needle subcutaneously to a depth corresponding to the tip of said rod, pulling said trigger while holding said handle stationary with one hand to allow said propelling means to move said carriage rearwardly and retract said needle from around said pellet so that said pellet(s) remain(s) subcutaneously implanted in said animal.

Claim 13

A process for subcutaneously implanting at least one biologically acceptable pellet in an animal using an apparatus including handle means for grasping said apparatus with one hand; a track attached to said handle means and having front and rear portions, said track being suitable for a carriage to move therealong; a carriage placed within said track and movable therealong with front and rear portions corresponding to the front and rear portions of said track, said carriage having (i) a recess in the front part of said carriage which is adapted to receive and retain a detachable needle having a passageway extending longitudinally through said needle, (ii) a flanged needle received and retained in said carriage recess, said needle having a barrel with a beveled, sharp end and an enlarged, flanged end, a passageway extending the length of said needle, and at least one pharmaceutically acceptable, implantable pellet in said needle passageway, (iii) passageway extending the length of said carriage parallel to the length of said track and corresponding to said needle passageway, and (iv) means to guide and stabilize said carriage along said track; propelling means to propel said carriage along said track from the front part to the rear part of said track; means attached to the rear part of said track to stop said carriage when propelled rearwardly; means attached to the front part of said track to retain said carriage; a straight, retractable rod attached to said stopping means so that the rod extends straight through said carriage passageway; means to retain said rod stationary or allow said rod to be retracted; a finger actuatable trigger attached to said handle which is designed to retain said carriage in a cocked position at the front part of said track and when actuated allows said carriage to be propelled rearwardly along said track and rod by force of said propelling means, which process comprises subcutaneously inserting said beveled, sharp end of said needle in said animal while said carriage is in the cocked position, forcing said needle subcutaneously to a depth corresponding to the tip of said rod, pulling said trigger while holding said handle stationary with one hand to allow said propelling means to move said carriage rearwardly and retract said needle from around said pellet so that said pellet(s) remain(s) subcutaneously implanted in said animal.

Claim 14

The process of claim 11 wherein a plurality of pellets are in said needle and are implanted in said animal simultaneously.
