Reason

During initial set-up and/or replacement of the dispenser batteries, the touch dispenser touchscreen can inadvertently lose calibration. This issue can also occur if the touchscreen is pressed when the device is powered on in preparation for a balloon administration. As a result, the touchscreen can become unresponsive and balloon inflation cannot be initiated.

Root cause

Software design

Action

To ensure that customers would receive the recall notification bulletin, and to ensure that the bulletin would not be lost in an email inbox, customers were contacted by telephone beginning on 5/23/2019 to notify them that they would be receiving an email containing the notification bulletin. These emails, first sent on 5/23/2019, contained Customer Bulletin no. LIT-7410-0025-01. The bulletin notified customers of the unintended functionality of the touchscreen during power-up, provided instructions to contact Obalon Customer Service immediately it this situation occurs, and contained updated instructions as to how to handle the device issue. Customers were instructed to contact the Obalon Customer Service/Technical Support department to obtain instructions for re-calibrating the touchscreen such that the device will function as designed and the balloon administration may proceed. Customers were requested to immediately report any events that occur with use of the system such that the firm can inform regulatory bodies and customers of any new device information and update labeling materials, where appropriate. Customers were informed that a permanent fix has been identified and once it has been reviewed and approved by FDA, all dispensers will be updated accordingly.
