Internal investigations have identified an issue with the durability of the connecting cable near the connection to the Venous Bubble Sensor. Excessive bending of the connecting cable can lead to full damage of the Venous Bubble Sensor or loose cable contact, which may trigger the errors Ven. bubble sensor defective or Ven. bubble sensor disconnected on the connected medical device. These errors can occur temporarily when the connecting cable is moved or permanently if the connection is fully compromised.

HKH 8820 Wall Holder does not comply with standard DIN EN 1789:20 and has the potential to detach.

Heart-Lung Machine GUI touchscreen may go dark for 10-15 seconds, safety/performance functions remain operational before reset, control maintained through backup control panel, but second reset may occur, may lead to gas blender standby, then gas blender must be reactivated using user interface on blender, sensors deactivated until new case started; GUI reset can lead to Hypoxia and Hypoperfusion.

The firm identified that the measured patient leakage current in some devices significantly exceeded expected levels.

The Bubble Sensor optional accessory to the CARDIOHELP-i extracorporeal life support system includes an incorrect UDI Device Identifier (DI) provided with the label attached to the device.

CARDIOHELP-i System was not properly tested to measure leakage current

Firm received complaints of breaks in the insulation, shielding, or wires of the venous probe connection cable. Fracture of the venous probe cable may influence the management of extracorporeal support. Patient may be exposed to inappropriate blood flow, blood temperature, or hematocrit/hemoglobin levels as a result of the CARDIOHELP-i not receiving information from the venous probe.

Certain factory settings for the device were incorrectly described in the IFU-related to the warning limits for PVen and PAux, and the default settings for the venous bubble sensor (VBS) and the automatic lock in the Minimized Extracorporeal Circulation (MECC) ThApp

It was found that the fixation (weld) employed by the supplier of the nut bolt to the slide rail plate was insufficient. The deficient weld allows the nut bolt to break off from the slide rail plate with slight manual force.

Product removal due to possible blocking or impairment of the CARDIOHELP Emergency Drive. This issue can lead to the patient being exposed to inappropriate low blood flow. Potential associated harms are ischemia and hypoxia.

1. An accessory may be improperly placed during packaging, causing creases and damage to the accessory's sterile pouch. 2. Product packaging may exhibit holes, cracks, dents, and crushed areas. Both issues may compromise the sterile barrier of the packaging, and exposure to non-sterile product may result in inflammation, infection, sepsis, and ischemia.

The ratchet and pawl had an out of tolerance geometry which exhibited as the left bobbin would not lock.

Potential for a loose cylindrical pin on the Transport Guard that may result in the jamming of the locking mechanism causing the Transport Guard to not open or, if the locking pin is fully disengaged from the assembly, a full disassembly of the Transport Guard may occur, resulting in a delay of support if a product exchange is necessary.

intermittent failure causes a blender initialization fault upon start-up, or during an EPGS calibration attempt following the 15-minute warm-up period. The control sliders on the Central Control Monitor (CCM) are disabled and the gas system can only be controlled by the local control knobs

Internal testing at the supplier, revealed that a crimped wire was placed into an air bubble detector (ABD) sensor connector backwards, preventing the crimped wire from locking into the mating wire connector. This intermittent connection may result in false air bubble alarms.

These roller pumps were assembled with pump shafts that may fail at the location of the thread where a locknut is installed. The failure is associated with a noise that is atypical of roller pump operation. The noise is caused when an unsecured shaft end contacts the rotating pulley of the roller pump. Prolonged use of a roller pump in this condition could lead to an eventual pump stop, resulting in the inability to create pump flow due to pulley loosening and drive belt damage.
