Abstract
Abstract Implants (50) may be placed in animals in the field with a system including an implanter (10) and cartridge-like container (30) for a plurality of implants. The cartridge is transparent and encloses a plurality of elongated implants arranged side-to-side, transverse to the longitudinal axis of the cartridge. The implants may be moved manually (33) along the longitudinal axis of the cartridge toward one end and stopped in alignment parallel with the end (39) of the cartridge and with one implant aligned with a pair of openings (37, 38) in the cartridge one opening at each end of the implant. The implanter carries a sharpened tubular needle (25) and a plunger, slidable along an axis aligned with the central axis of the tubular needie. The implanter has an opening (20) into which the cartridge may be fitted and retained. The implanter and cartridge have interfitting surfaces (28a. 28b. 27, 31c, 31d) to position the cartridge with its pair of openings lying upon the central axis of the hollow needle and to retain the cartridge in the implanter so that the plunger may be passed repeatedly through the pair of openings in the cartridge and move the implants, one after the other, through the sharpened tubular needle (25) into the animals. The implants thus are protected from contamination until implantation.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
219 words
An implanter, comprising: an implanter body (11) having a forward portion and a rearward portion and forming a central bore, an elongated slot (12) formed between the outer surface of the body and the central bore, a rectangular opening (20) adjacent the forward portion of the body between the central bore and the outer surface of the body, said rectangular opening having a central axis that is transverse to the elongated slot and central bore, the forward portion of the implanter body being adapted so as to be capable of detachably engaging a hollow tube (25) having a sharpened forward end (25a) so as to position its bore in alignment with the axis of the central bore of the implanter body (11), and a plunger, including an elongated rod (14) and a web (15) extending transversely through said slot, slidably carried in the implanter body and having a surface of the web (16) outside of the implanter body, the central bore guiding the forward end of the elongated rod along an axis extending through the positioned bore of the hollow tube (25) when the plunger slides forwardly within the implanter body, and the forward end of the elongated rod lying rearwardly of the rectangular opening (20) of the implanter body when the plunger slides rearwardly within the implanter body.
Claim 2
Dependent Claim
219 words
An implanter, comprising: an implanter body (11) having a forward portion and a rearward portion and forming a central bore, an elongated slot (12) formed between the outer surface of the body and the central bore, a rectangular opening (20) adjacent the forward portion of the body between the central bore and the outer surface of the body, said rectangular opening having a central axis that is transverse to the elongated slot and central bore, the forward portion of the implanter body being adapted so as to be capable of detachably engaging a hollow tube (25) having a sharpened forward end (25a) so as to position its bore in alignment with the axis of the central bore of the implanter body (11), and a plunger, including an elongated rod (14) and a web (15) extending transversely through said slot, slidably carried in the implanter body and having a surface of the web (16) outside of the implanter body, the central bore guiding the forward end of the elongated rod along an axis extending through the positioned bore of the hollow tube (25) when the plunger slides forwardly within the implanter body, and the forward end of the elongated rod lying rearwardly of the rectangular opening (20) of the implanter body when the plunger slides rearwardly within the implanter body.
Claim 3
Dependent Claim
111 words
An implanter as claimed in claim 1 in which the forward portion of the implanter body comprises a split, conical, and threaded outer surface (22, 22a) surrounding the central bore, and a coaxial inner surface adapted to engage the hollow tube and to position its bore (21a, 23) in alignment with the axis of the central bore of the implanter body, and a threaded cap (24) having an inner conical surface (24a) which mates with the split, conical, and threaded surface of the body to compress the surface as the cap is threaded on the forward end of the implanter body to engage and retain the hollow tube (25) in position.
Claim 4
Dependent Claim
91 words
An implanter as claimed in claim 1 or 2 in which the implanter body comprises, at its central slot, and the web (15) of the plunger, interengaging surfaces (llc, lld) to retain the plunger with the forward end of the elongated rod lying rearwardly of the rectangular opening and having interengaging surfaces at a mid-point of the central slot to impede the travel of the plunger and hold the plunger with the forward portion of the elongated rod within and spaced rearwardly of the forward end of the hollow tube .-
Claim 5
Dependent Claim
71 words
An implant container comprising: a cartridge (30), including a rectanqular tray-like portion (31), containing a plurality of implants (50) and a slotted top (32) and an implant pusher (33) between the tray-like portion and top with an outwardly projecting button (34) extending throuqh the slotted top to permit movement of the pusher, the tray-like portion forming two sides having aligned openings (37, 38) larger than the cross-sectional area of the implants.
Claim 6
Dependent Claim
71 words
An implant container comprising: a cartridge (30), including a rectanqular tray-like portion (31), containing a plurality of implants (50) and a slotted top (32) and an implant pusher (33) between the tray-like portion and top with an outwardly projecting button (34) extending throuqh the slotted top to permit movement of the pusher, the tray-like portion forming two sides having aligned openings (37, 38) larger than the cross-sectional area of the implants.
Claim 7
Dependent Claim
49 words
An implant container as claimed in claim 4 wherein the pusher comprises a surface which forms a pointer (33b) and the cartridge comprises a sequence of numbers (32b) related to the number of implants within the cartridge whereby said pointer indicates the number of implants remaining within the cartridge.
Claim 8
Dependent Claim
43 words
The container as claimed in anv one of claims 4-5 wherein the cartridge tray-like portion, the top, and the pusher are adapted to impede the advancement (31e, 33a) and retraction of the implant pusher and to retain the pusher against movement by gravity.
Claim 9
Dependent Claim
40 words
The container of claim 6 wherein the tray-like portion includes a plurality of detents (31e) spaced equally in a row a distance equal to the thickness of an implant, said implant pusher including ratchet teeth (33a) to engage the detents.
Claim 10
Dependent Claim

The implant container of claims 4-7 comprising a projecting tab (31c, 31d) on the sides of the cartridge tray-like portion adjacent the aligned openings.
Claim 11
Dependent Claim
