Abstract
A structure for in vivo implantation which includes an elongate section terminating in one end in an enlarged portion and being at least partially of a biocompatible porous material having characteristics of promoting ingrowth of tissue. The structure is adapted to be implanted in place of at least a portion of the bony chain of the middle ear, to serve as a plug for a tube, or to serve as an implant electrode. The same structure including a means for closing the pores of the intermediate portion of such structure may be used in place of all or a portion of the bony chain between the ear drum and the vestibule.
