(b)(4).On (b)(6) 2017, it was reported from (b)(6) hospital that fluid was leaking from the bottom of the cart.(b)(4) was contacted about the cart and dispatched a service technician to be at the site the following day.On 22 february 2017, the technician arrived at the site and confirmed that the cart was leaking fluid.He then discovered upon further inspection that there was a crack in the drain fitting below cylinder #1.An exchange was scheduled for the cart.On 22 february 2017, a new cart (serial # (b)(4)) was shipped from dornoch to the hospital.The cart was confirmed to have arrived at the site on 23 february 2017 and a service technician from (b)(4) was dispatched to the site to perform the exchange.On 24 february 2017, the technician arrived at the site and installed the new cart.The technician verified that the cart was functioning as intended and then placed the cart into service without further incident.The technician then repackaged the device, so that it could be returned to dornoch.The product was noted to have been 28 february 2017 and a returned product investigation was performed on the device on 1 march 2017.It was noted during the investigation that there was a crack at the drain hole on the bottom plate for cylinder #1 and that fluid was leaking out through the bottom of the cylinder plate.Intellicart system, serial number (b)(4), was manufactured on 28 december 2016 and was 2 months old at the time this complaint was generated.The device history record (dhr) review noted no related non-conformances, requests for deviation (rfd), change notices (cn), or any other issues with manufacturing.The dhr review found no issues with the device and all verifications, inspections, and tests were successfully completed.Using crm to query for serial number (b)(4), the device was noted to have not been previously repaired by zimmer biomet surgical.Review of all notifications of defect for the cylinder bottom plate revealed that there was one associated with the drain hole on the cylinder bottom plate having a crack through it ((b)(4)).The work order that the complaint is associated with is listed within the scope of the investigation, so the notification of defect is related to the reported event.No complaint history review from the etq reliance system can be performed since the intellicart is new product that had been only recently released to market.The root cause of the cart leaking from the bottom of the device could not be specifically determined, but was most likely due to a design flaw with a previous version of the cylinder bottom plate as noted in notification of defect (b)(4).The cylinder bottom plate found within the cart was noted to have been associated with an earlier revision of the component.The cylinder bottom plate was also noted to have been updated to add a flat area under the cylinder to prevent flexing and increase the long term reliability of the component as well as had the ribs attached to the drain port and spray head opening raised to increase support to the molding knit lines at the drain port and spray head openings.The lower ribs attached to the drain port and the unflatten surface on the previous version of the cylinder bottom plate would have not allowed the drain port to have the necessary support to withstand the applied force that the molding knit line on the drain port would be exposed to when the device would be operated.When the customer would then attempt to operate the device, the applied force on the drain port could then cause the mold to break down at an accelerated rate at the molding knit line and therefore cause the component to fracture along this line.The fracture drain port would then allow fluid to seep out from the drainage line and therefore out into the basin of the cart.The fluid could then leak out the bottom of the cart through the ventilation ports located in the bottom of the cart.If any information is found which would change or alter any conclusions or information, a supplemental will be filed accordingly.Zimmer biomet will continue to monitor for trends.
