(b)(4).
Customer returned one used spring-wire guide (swg) with the swg assembly.
A visual inspection of the swg revealed one kink and a bend in the swg body.
Microscopic examination of the guide wire confirmed the kink and bend.
There are offset coils at the kink.
Both welds were present and were observed to be full and spherical.
The kink and bend in the swg were located approximately 2.
0 and 3.
4 cm from the distal end of the swg, respectively.
The swg length and outer diameter were measured and were found to be within specification.
A manual tug test confirmed that both welds remain intact.
The lot number was not reported; however, a device history record (dhr) review was performed based on a lot number from the sales history data of the customer.
No relevant findings were identified.
The instructions-for-use (ifu) provided with this kit describes suggested techniques to minimize the likelihood of guide wire damage during use.
The instructions caution that withdrawing the guide wire against the needle bevel or use of excessive force during removal could damage or break the wire.
The reported complaint that the swg was kinked was confirmed based on visual inspections of the returned sample.
A kink and a bend were both found in the swg body.
The returned guide wire met all relevant dimensional requirements and a dhr review did not identify any manufacturing related issues.
Based on the condition of the guide wire and the report that the damage was observed during use, it was determined that operational context caused or contributed to this event.
Teleflex will continue to monitor and trend for reports of this nature.
