The non-hermetically sealed pacemaker myth, or, Navy-Ribicoff 22,000- FDA-Weinberger o
GF Tyers and RR Brownlee
Although the Secretary of Health, Education and Welfare recently stated
that hermetic sealing of all implanted cardiac pacemakers, as recommended
by the Navy in 1969, is inadvisable, several small manufacturers are
already marketing hermetically sealed devices (CPI, Pacesetter), all of the
over 600 nuclear pacers implanted to date have been hermetically sealed,
and belatedly the major manufacturers are developing hermetically sealed
units. Total hermetic sealing of all implantable electronic devices has
been technically feasible for years, and it is essential that device
legislation include mandatory encapsulation standards.
