Successful Medtronic Champion 8072 pacemaker pulse generator destructive-replacement for lead-pin/lead-port clip aperture misalignment

摘要

Medtronic introduced low-cost Champion VVI pacing devicesfor use in countries such as India a few years ago and weresubsequently withdrawn. These devices are still beingencountered when patients with devices present themselvesfor battery replacement. Figures 1 and 2 show the method offinger pressure application over the implantable pulsegenerator (IPG) header in order to align the pair of aperturesfor correct lead-pin insertion or removal and Figure 3 depictsa correctly engaged lead-pin. Although very simple in designwe describe a problem faced at pacemaker IPG replacementdue to lead-pin misalignment in the lead-port.
