MAUDE Adverse Event Report: BOSTON SCIENTIFIC CORPORATION LATITUDE PROGRAMMING SYSTEM; EXTERNAL PROGRAMMER

Model Number	3300
Medical Device Problem Code	Key or Button Unresponsive/not Working (4063)
Health Effect - Clinical Code	No Clinical Signs, Symptoms or Conditions (4582)
Date of Event	04/11/2025
Type of Reportable Event	Malfunction
Additional Manufacturer Narrative
The device was not returned for product analysis.Boston scientific performed an investigation with all available information.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.The investigation determined that the cause of touchscreens becoming unresponsive during use was due to the water detection feature within the programmer's liquid crystal display (lcd) touchscreen assembly.Various inputs can induce false positive detections of this water detection feature, which then results in an unresponsive touchscreen.
Event or Problem Description
It was reported that this integrated programmer exhibited a screen issue, it was unresponsive.Boston scientific technical service (ts) assisted in troubleshooting but was unresolved.The programmer remains in service.No adverse patient effects were reported.
Event or Problem Description
It was reported that this integrated programmer exhibited a screen issue, it was unresponsive.Boston scientific technical service (ts) assisted in troubleshooting but was unresolved.The programmer remains in service.No adverse patient effects were reported.The programmer was returned and investigated.Field observation of unresponsive touchscreen was confirmed, and error codes were documented.Broken traces attributing to an unresponsive touchscreen is consistent with capa-00006695.
Additional Manufacturer Narrative
Supplemental additional information with product return.This programmer was thoroughly inspected and analyzed upon receipt at our quality assurance laboratory, including functional and baseline testing, and review of device memory.The programmer passed all testing and analysis was unable to confirm the allegation of an unresponsive touchscreen.The touchscreen operated as intended and exhibited no unresponsive behavior.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.
