The potential for purge cassette recognition issues due to the failure of the purge flag component of the purge pressure sensor assembly.

A potential for introducer sheath leakage from under the sheath cap and along the hub score lines, identified in 14Fr and 23Fr Introducers. These manufacturing issues are not visually detectable by the user, and 14Fr or 23Fr Introducers are provided in every pump set.

Potential for thrombus formation during prolonged use of the introducer.

Exposure to the low purge pressure occurrence may result in persistent low purge pressure alarms and, in some cases, interruption or loss of mechanical circulatory support.

Potential software error in the Automated Impella Controller ("AIC" ) when used in conjunction with left ventricular Impella devices.

A retrospective review identified that there are AIC units requiring specific hardware updates to address potential safety concerns. These hardware updates have been implemented through Abiomed s servicing process; therefore, AICs that have not received service are pending these …

Increased risk of purge leaks with Generation 1 purge cassettes.

Potential that the "Purge System Blocked" alarm display on the Automated Impella Controller (AIC) could be delayed when using first generation Impella 5.5 (0550-0008*) pumps.

Differential pressure (dP) sensor in Impella RP devices may malfunction, causing sensor values to drift.

Device packaged in incorrect outer box carton.

Potential cybersecurity vulnerabilities related to the operating system in the Automated Impella Controller (AIC).

Potential for Automated Impella Controller (AIC) purge pressure issues due to purge retainer failures.

Specific Automated Impella Controllers (AICs) that have a Pump Driver Circuit Assembly do not meet current specifications. This may lead to decreased pump performance or pump stop and trigger an Impella Failure or Impella Stopped Controller Failure alarm.

A potential issue with the Automated Impella Controller (AIC) not detecting an Impella pump when it is connected

Optical Sensors have been damaged due to physical interaction between the inlet and another device resulting in a Placement Signal Not Reliable (PSNR) alarm and loss of Central Venous (CV) Placement Signal, Pulmonary Artery (PA) Placement Signal & Pulmonary Artery Pulse Index (PA…

A potential device interaction between the Shockwave Coronary IVL Catheter and left-sided Impella Pumps during coronary interventions. Currently there is no Abiomed labeling (IFU etc.) content related to this potential interaction, so Abiomed will update the IFU to include inform…

Nine (9) Impella CP pumps failed inspection and were inadvertently released.

New warnings are being added to the Instructions for Use for all affected products to reduce the possibility of fibers being drawn into the Impella, which may result in low flow of the device.

IFU has been updated to include warnings about the risk of the inlet perforating through the myocardial wall of the left ventricle due to operator handling.

The following features have been disabled from the web-based portal because the FDA has not evaluated these features for safety and effectiveness: Notifications via email feature; AIC alarm color on case tile feature; Sort case tiles by AIC alarm color feature; Pump metric dis…

Hole(s) to the outer pouch of the Introducer Kits (both trayed and non-trayed) may compromise the sterile barrier of the Introducer Kits. Non-sterile product exposes patients to the possibility of the introduction of micro-organisms into the vasculature and/or access site, leadin…

Pump not detected as connected to controller due to software issue.

A higher than expected rate of thrombus formation or deposition has been observed. The risk is for thrombus formations or deposits on indwelling central venous lines or cannulas may break free and enter into the Impella RP Flex, resulting in reduced flow, loss of support, or hem…

There is a potential risk for unintentional interaction of the Impella motor housing with the distal stent of a transcatheter aortic valve replacement (TAVR) resulting in destruction of the impeller blades. This has resulted in low flow from the damaged Impella system. Systemic e…

There was one complaint that the sidearm of the device detached during explant of a pump. When the sidearms are subjected to heat, humidity and articulation, a silicone oil contaminant that was unintentionally introduced during manufacturing at the joint between the sidearm and …

The Impella 5.5 pump experienced a heightened complaint rate for purge leaks.

The firm has received complaints of the OXY-1 System Console experiencing a power interruption while in use, which disrupts therapy delivered to a patient on support. Disruption of therapy could lead to prolonged hypoxia.

Retrospective reporting for the release of Technical Bulletin IMP-2643 AIC Version 8.5 Software Update Available. The update resolved an issue in version 8.4 where a pump was not recognized by the AIC.

This one pump shipped with incorrect pump programming, the initial production working version of the program. The pump would have immediately run at P9 for all selected P-levels, rather than a 10 second ramp up period. The pump may have migrated out of position and possibly cause…

Retrospective report of issues remedied in 2019 with firmware and software patches: 1. Defects in optical bench (OPB) firmware V2.19, which affected the accuracy and stability of the pressure signal the AIC system performance depends on. 2. Software defects leading to unreliab…

Retrospective submission for following issues identified: 1. Alarm failures, power-path faults, electrical-short risks, and inaccurate motor-current sensing were identified in certain AIC consoles. 2. There is improper alignment between the purge cassette and the motor drive …
