Patent number: 9700713Abstract: The present invention relates to active implantable medical stimulation devices. An active implantable medical stimulation device comprises an electrically non-conductive support member, one or more electrically conductive stimulation electrodes disposed on the support member and a cover covering the support member and the one or more electrodes. At locations where the cover covers the electrodes, the cover comprises one or more openings dimensioned such that the one or more openings which facilitate electrical conduction to allow stimulation of tissue and/or measurement of electrical signal s by the electrodes while preventing tissue ingrowth. The support member can be of an advantageous structure, that would not be usable without the cover since tissue in-growth would not allow the removal of the implant. At the same time, the cover still allows the stimulation of the tissue so that the functionality of the device is not prevented by the cover.Type: GrantFiled: November 26, 2012Date of Patent: July 11, 2017Assignee: SALUDA MEDICAL PTY LIMITEDInventors: David Robinson, Mark Fretz, David Thomas, John Luis Parker
