Abstract
Apparatus and method according to the disclosure relate to a substantially transparent shroud member and a substantially clear header portion adapted to mechanically and electrically couple to an implantable medical device (IMD). The assembly is used to provide a subcutaneous cardiac activity sensing device via at least a pair of electrodes mechanically coupled to the shroud member. The assemblies provided according to the disclosure allow complete visual inspection of all exterior components of an IMD, and for clamshell-type IMD housings provide increased hermeticity to the assembled device.
