ABSTRACT:
An article of manufacture for use as an implant in the animal ear to correct a faulty carriage of the ear occasioned by the presence of a skin-enclosed cartilage fault comprises a spring constructed of non-porous biologically inert material, the spring having outwardly divergent arms terminating in outer free ends and adapted to be forced together to present a narrow elongated spring outline for implantation of the spring in the ear by insertion through a small incision in the skin of the ear with the free ends foremost and into a pocket previously formed between the skin and cartilage over a cartilage fault, so that the spring bridges the fault, the spring arms when free of applied force tending to return to their original divergent dispositions owing to the resiliency of the spring, whereby when the spring is implanted in the ear, the spring arms resist displacement of the spring towards the incision. The article is especially adapted for use as the implant in the implantation method in which a cannula-like sheath is inserted through the incision and into the pocket, so that the sheath bridges the fault, an elongated ear implant is inserted endwise in the sheath, and the sheath is removed from the pocket and from around the implant to deposit the implant in the ear in bridging relationship to the fault.
