The lot number was reviewed for complaint trend, nonconforming reports and capa review.No trends were noted.The device has been received at coloplast; however the evaluation is not yet complete.Without the benefit of examination and testing, coloplast is precluded from commenting on the condition of the device or the cause of the occurrence.Once our evaluation is complete, a follow-up report will be submitted.

This follow-up mdr is created to document the evaluation of the returned device.A titan pump, two cylinders and detached inlet tube with connector were received for evaluation.Examination and testing of the returned components revealed partial separations within abrasion on the longer exhaust tube of the pump and shorter end of the detached inlet tube with connector.Testing revealed these to not be sites of leakage.Abrasion was also noted on the inlet tube of the pump and exhaust tube of cylinder 1.Microscopic examination of the detachment ends revealed the shorter exhaust tube of the pump and exhaust tube of cylinder 2 to be rough and irregular, indicating stress was exerted.No functional abnormalities were noted with the pump, either cylinder or detached inlet tube with connector.Based on examination of the returned product, it was concluded that while in-vivo both the exhaust tubes and inlet tube of the pump had overlapped and abraded against one another.This positioning, in combination with device usage over time, could most likely contribute to sufficient stress(s) to separate the shorter exhaust tubing.A separation of this type would then allow the loss of fluid, making the device inoperable.A review of the device history record confirmed the devices from this lot met all specifications prior to release.A review of the complaint history database, nonconformance's and capas revealed no trends for this lot.
