Improvements in or relating to implanters

摘要

An implanter 1 for introducing an implant 6 under the skin of a human or animal body comprises a needle holder 3 for a hollow needle 4 having a tip 5 within which the implant 6 is accommodated and by means of which the implant 6 is introduced under the skin, a plunger 7 for relative movement within the needle 4, and a depth guide in the form of a hollow sleeve 15 for contacting the surface of the skin during introduction of the needle tip 5 under the skin. The hollow sleeve 15 serves to effect relative movement between the needle 4 and the plunger 7 when the needle tip 5 has been introduced under the skin to a required depth in order to cause the implant 6 to be left at the required depth when the needle tip 5 is withdrawn. Such an implanter 1 allows the implant 6 to be located accurately within the body and thus avoids the problems associated with incorrect placing of the implant. <IMAGE> <IMAGE>
