Model Number	3300
Medical Device Problem Codes	Nonstandard Device (1420); Failure to Power Up (1476)
Health Effect - Clinical Code	No Clinical Signs, Symptoms or Conditions (4582)
Date of Event	08/19/2025
Type of Reportable Event	Malfunction
Additional Manufacturer Narrative
This programmer was thoroughly inspected and analyzed upon receipt at our quality assurance laboratory, including visual inspection, functional and baseline testing, and review of device memory.Analysis confirmed the programmer touchscreen was unresponsive due to not detecting touch inputs.Broken traces were noted on a flexible cable within the touchscreen assembly, which resulted in the clinical observation of an unresponsive touchscreen.An unresponsive touchscreen is a known and anticipated potential hazard that can occur during use of the device which is accounted for in device risk documentation and labeling.Boston scientific has received similar reported events where the latitude programmer screen became unresponsive to touch and a complaint review confirmed that the occurrence of harm associated with these events is low.Investigation of this behavior has not found any commonalities (i.E., device serial numbers, date of the event, date of manufacture, etc.) in the reports received.Investigation determined that the most common cause of the touchscreen becoming unresponsive during use was the water detection feature within the programmer's liquid crystal display (lcd) touchscreen assembly.The purpose of this water detection feature is to detect the presence of water on/near the programmer screen.If water is detected, this feature is designed to disable the touchscreen to prevent water droplets from causing false positive touch inputs during use.Specifically, the investigation determined that various inputs could induce false positive detections of this water detection feature, which then results in an unresponsive touchscreen.Boston scientific's investigation also identified additional potential causes independent of the water detection feature.These include a variety of unrelated root causes such as hardware, environmental, software, and user-related causes that can be intermittent and not reproducible during laboratory analysis.A review of the device history record (dhr) was performed.The review of the dhr identified that there were no process related non-conformances, scrap, or rework performed during the production that could explain the event.The reviews ensure each device meets specification prior to release for use.There is no indication the device manufacturing process contributed to the reported complaint.Review of labeling determined the complaint situation was listed in the manual.There was no indication in the complaint that the product was not used in accordance to labeling.The manual was unlikely to be the cause of the reported complaint; translation, wording, or graphics does not require further review.A risk review was completed and confirmed that the event of failure to power-up using battery was defined in the risk documentation.This event type has been accounted for during product risk analysis to support acceptable benefit risk for the product.Based on a thorough review of the reported complaint, boston scientific has assigned an investigation conclusion code of cause traced to device design based on the analysis of the returned product which was found to be consistent with capa-00006695 3300 programmer unresponsive screen during threshold testing, that is evidence of an unresponsive touchscreen.The capa investigation deemed this a design failure.
Event or Problem Description
It was reported that this integrated programmer was unable to power up even if charging the battery.Boston scientific technical services consultant advised for product return.Additional information indicated that the reported anomaly with this prm was resolved.This programmer was out of service and returned for repair, and a replacement was ordered.There was no patient involvement.
