Users were reporting that the device was not charging as expected. It was discovered that users were unaware that the Cardiosave console was not completely inserted into the hospital cart. If the console is not fully inserted back into the cart the battery(ies) will not charge.
Users were reporting instances of "Gas Loss in IAB Circuit" and "Gas Gain in IAB Circuit" alarms while providing therapy. An internal investigation of the complaints determined that there is a potential trigger for these alarms that was not listed in the IFU: Patient Movement (coughing, general movement, and swallowing). Blood in the circuit, kins and abrasions of the tubing/catheter and certain patient conditions could also trigger these alarms. The HHE also identified hardware issues related to these alarms.

When the control of the operating table was used in Bluetooth mode, the operating table continued moving even after releasing the button on the control. Originally, the root cause was thought to be confined to Bluetooth/wireless communications between the control pendant and the surgical table. However, during investigation, Mizuho discovered that the failure could be replicated even in wired mode if communication between the pendant and table were somehow interrupted. The root cause appears to be: if communication between the controller and table is interrupted while a button is pressed, the table does not know if/when a button is released. This occurs in wireless or wired mode.

Due to a manufacturing issue, when using valve repair systems, intended to repair insufficient mitral and/or tricuspid valves, users experienced resistance when attempting to release the implant from the delivery system by rotating the release knob. Additional torque required to initiate rotation of the release wire from the implant, could cause implant rotation or additional implant implantation.
