Manufacturer Narrative

A preliminary review showed there were no manufacturing rejects or anomalies of this event type recorded in the device history record.A conclusion is not yet available as the investigation is on-going.

Event Description

Patient was in for an upgrade from a dc pacemaker to a bi-v device.The old system was on the left side, but the vein was occluded so the implanter decided to put the new system on the right side.He decided to keep the old rv lead and use an oscor adapter to bring it over to the right.A new ra and lv lead were implanted on the right.After the pocket was closed, the patient woke up and moved his arms such that there seemed to be some disruption in the rv lead.Lead impedances changed from 551 to >3000 ohms.There was also noise on the lead with pocket manipulation.Doctor went back into the pocket to re-set the rv lead in the adapter.After they did this, the rv impedance was 720 ohms and the noise was gone.However, the doctor and the rep were unhappy that the impedance was now a little higher than the initial 550 and were not sure the adapter was ok.The patient was programmed to voo and will be kept overnight.

Manufacturer Narrative

The device was in use for treatment.The device was not returned for analysis, therefore the clinical observation could not be confirmed.The investigation will focus on a review of product documentation.There were no manufacturing rejects or anomalies of this event type recorded in the device history record.Based on the investigation, a capa is not required as findings did not identify a design, labeling or manufacturing non-conformity.In addition, there was no new failure mode identified and the risk remains acceptable.The event will be re-evaluated if additional information becomes available.Oscor will continue to monitor this event type and risk.Per bipolar is -1 receptacle assembliy in-process & final inspection procedure, devices are inspected 100% as follows: 7.2 electrical/mechanical inspection: check electrical continuity by using multimeter set at normal operation or "buzzer" option.Attach one cable to the extended inner coil and the other cable to the trokar needle.Insert trokar needle straight on the screw head through the seal of the inner part m2 receptacle and check for continuity.Insert the trokar needle into the other screw head through the seal of the anode contact receptacle to assure that there is no electrical connection/short.Leave the trokar needle in contact with the anode contact and attach the red cable to the outer hull to check for continuity.Per instructions for use, (ifu) bis/bis adaptor: the adaptors are implanted in the extremely hostile environment of the human body.Because the adaptors are very small in diameter and must be very flexible, it inevitably reduces their potential performance and longevity.Adaptors may fail to function for a variety of causes, including medical complications, body rejection phenomenon, allergic reaction, fibrotic tissue problem, or a failure of adaptor by damage, fracture, or by breach of their insulation.Despite of all due care in design, component quality, manufacture and testing prior to sale, adaptors may be damaged by improper handling, use, placement or other intervening facts.Oscor inc.Is submitting the above report to comply with 21 cfr part 803, the medical device reporting regulation.The report is based upon information obtained by oscor inc.Which the company may not have been able to investigate or verify prior to the date the report was required by fda.This report does not constitute an admission that the device, oscor inc., or its employees, caused or contributed to the event described in this report.Nor does this report reflect a conclusion by fda, oscor inc., or its employees, that the report constitutes an admission that the device, oscor inc., or its employees caused or contributed to the event described in this report.
