Abstract
Abstract of the Disclosure Implants may be placed in animals in the field with a system including an implanter and cartridge-like container for a plurality of implants.
The cartridge is transparent and encloses a plurality of enlongated implants arranged side-to-side, transverse to the longitudinal axis of the cartridge. The implants may be moved manually along the longitudinal axis of the cartridge toward one end and stopped in alignment parallel with the end of the cartridge and with one implant aligned with a pair of openings in the cartridge, one opening at each end of the implant. The implanter carries a sharpened tubular needle and a plunger, slidable along an axis aligned with the central axis of the tubular needle. The implanter has an opening into which the cartridge may be fitted and retained. The implanter and cartridge have interfitting surfaces 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 into the animals. The implants thus are protected from contamination until implantation.

This i.n~renti~c n pf.?.rmits thP h~nclJ incJ o.~
implantC- ~t SUC]l rf?mOt.e sites ~`lit}lO~t C-)nt~.mitlation.
In o~e c~SPt?Ct of thi,s in~ention, a plura].it~ of implants are contained in ~ transparent, clean enclosurf?. The i m~lan.ts a~e placecl thf?n in ~he animal with an implantf?r device which includes a sharPened holl.ow tuhe. The contc~iner h~s a p~ir Ols alia,ned o~eninqs at one ~nd, and the impl~r.ter ancl contalnc?r have lnt,f?xfjttinq surfacf?s adapted to pe~mit the container to be positionecl and retained on the implanter. The pluralitY of implants mav be moved o~e-bv-one and stopped in aliqnment parallel with the end of the packaqe and with the pair of openin~s. When the cartrid~e is in Position on the implanter, its pair of openinqs lie in aliqnment with the central a~is of the hollow needle of the implanter. A plun~er is carried within the im~lanter anc~ is slidable alon~ an axis ali~ned with the cen-tral a~is of the sharpene~
hollow tube. The plun~er mav slide through the containf?r openin~s, enqaqe an imp3ant, ~nd move the im~3ant throuqh the sharpene~ hollow tube into the animal. The implants ma~,~ he moved, one after the other, aloncl the cf-!ntral a~i~ of the ~ontainer, permittinq the svstem t-o place the implants, one after another, into animals.
The implanter of the s-c~stem inclu~es c?. bod~
h2vinq a Forw~r~ ~?ortion and a rear ~ortion foxminq a ?0 central bore. The imPlanter hodv also forms an e30n~c~te~ slot betweell the Outel- scllrface ~ r the body and thf? centr~l hor(-? and a rectanqular o~enlnq adiacent the forwarfl portion ot the hodv. The rectan~ular openin~ has its cr?ntral a,~is tran~verse to the a~f?s of the elol~qated slot and centl-al bore. The orward portion of the i~planter bodY is adc~pted to accept and en~a~e a shax!7en.-?cl holl.7w tube and to ~70sition its bore in ali~nmert with the a~is of the central bore of the implanter bodv. ~he plunf~f?r which is slidably carried ~f~
in thf-' central bore of tne bodv includes an elonf~ted rod ~nd a wel~ e~tencling transversf?ly through the elongatQd slo-t. A surrace aclapteci for enqagement bv the thumb or Sinqers of an operator e~ctends transverselv from the web to the outside of the implarter bodv to pf?rmit the plunqer to be operated.
r~hen the ~lunqer is f~perated, the central bore quic~es the forward encl of the elonq~ted rocl through the bore of the hollow tube. In its rearw~rd position, ti1e for~ard end of the elongated rod lies rea.-warc~ly of the rect~nqular o~t~ning of thP implantf-~r bodv.
The impl~nt f~-?nC105Urf.? ~ or cont~inf?r, comprises a cartridc~f-? for use with thf~ implanter. The cartridclf? includes a tray-li3ce portion and a slotted ~on wit31 ~n im;~l~n~ ~ushf~r bf?twf?en thf? tr~v-likf-?
porticn and thf top. Thf? pusher has an outwardl~
proiectinq t;?b f~tenc?.ing throuah the slot in thf~ top to permit the user to mot~e the pusher manuallv. The pusher con~enif?ntl~ incluc~es a surfacf? t~hich form~s a n ~ointer, ancl the cartridqe oreff?rablv includes a sfquencf of numbe~s related to thf-' num~er ~l imPlants rema;nillcr wlthin the c~rtridqe. The tr~v-lilce port~ion of the cartridc~t? forms t~c~ sic~ ?s haV;.IlC~ aliqnf?d op-?ninc~s larqer than thf* cross-sec~tional. arf~ of thf~?
im~lants that it cont~ins. The c~rtridc~e and the cont3int--?d pusher ma~ be ac~pted to precluc1e thf?
advancement and retraction of the pusher and to retain the l?usher ac~ainst mot~ement by qra~itv in order that the implants mav ~e retained in their ~rallel 3~3~
side-bv-side arrarqement. One mannf?l^ of acco~plishinq this is to ~rovide rhe trav-li]ct? ?ortion with a pluralitv o~ detents spaced equallv in a row at a dista~ce equal to the thlckness o~ an implant ~nd pxovidin~ tne im~lant ~usher with r~tchet teeth to en~aqf the detents.
For use in the field, it is desirable that the implant plunger be retained rearwardly within the implanter so that its forwardmost end is rearward of the rectanqul~r openinq into which the c~rtridqe fits.
The cartrid~t? a~d imp]ants are thus free ~f interfl?renct? as thev are placed within the lmpl~ntt?r.
:tn use, the shar~ened tuhe will he inserted into and e~becldf?d in the animal's hod~, preferab]y the lS animal's ear. Because user.s mav want to wit~draw the impla~ter as the implant ls beinq pushed from its interior and are unable to see the tuhe openin~, the user wlll want to }cnow when the implant is leavin~ the fcrward end of the hollow tube. It is advisa~le therefcre, to si.~nal the us*r when the imnlal~t is ~bout to be e~ell~d from t.he forward ~nd of the sharpenecl tube into ~h~ animal. It is a~lvis~hl* also to retain the movement of the plun~er ln a ~oslt:ion wher~? the impl<ant is not ver e~cposed ~t th~?. forward portlon of ~he hollow tube to ~re~ent the implant frcm be-nq e~osed, or expellecl accidentallv from the implanter.
Tc ac~omplish 'hesQ qoals, the imp!anter, at its centr~! ~]ot an~ at the web of the plunger, preferablv is nrctided witn interenqaginq surfaces adjacent the rear ol the central slot to retain the plunger with its lorward end l.vina rearwardltt of the rectangular openinq in the implanter. In addition, such interenclaginq surfaces mav be provided al a mid-point in the central slot, positioned to impede the travel of the plunger and to hold the plunger in position with the forward portion of its eiongated rod within and spaced rearwardly from the forward end of the hollow tube a distanoe about equal to the length o an implan-t.
TJ-;ing the svstem of this invention, a plurality of implant~s cc~.n be pro~rided t~ithin a closed container that can be maintained freeQ. of contamin~nts and transportQd to a remote site for use. At such a site, the container can be opened and placed in position on t'ne imp1anter so thc~t the implants within the container are protected from dirt and contamination at the site. With the container in position on the implanter, the implants can be placed one af-ter another into a plurality of animals. S~lch a svstem and method maintains the implant in a clean condition during its trans~ortation and ha~dlinq, and ~ermits the implant to he placed iIl an animal t~ithout contamitnation.
The implanter is 1inhtweiclht ~nd easy to use.
Its ~eatures ~erm.it the st.raic3ht-line application of force ~ith one han(l along the a~is of `he implanter.
The container, with its plu-alitv of doses, pe~mits the -tr~atment of a plurality o~ animals without e~te~sive container h~ndlincT and at a reasonc~ble cost per dose.
The containers are small and are sealed against cont~mination, ?nc~ a number of con~-tiners mav b~ eac..ily carried bv users to the remote site of use.
