The reported complaint of lead could not be inserted into the connector was confirmed.Analysis found the atrial (a)- and ventricular (v) -setscrews were down in the in the a- and v-connector ports blocking lead insertion.Analysis found the setscrews had been tightened down by a someone in the field.For analysis testing the setscrews were backed out from the blocking the ports.The is-1 leads could then be fully inserted into the connector ports.Normal insertion force was used to insert the leads.All connector dimensions were within specification.No device anomalies were found that would cause a lead insertion problem.The setscrews blocking the ports were caused by a user in the field.
