What is this?

Alerts provide important information and recommendations about products. Even though an alert has been issued, it does not necessarily mean a product is considered to be unsafe. Safety Alerts, addressed to health workers and users, may include recalls. They can be written by manufacturers, but also by health officials.

  • Extra notes in the data
    In consultation with our Patient Safety Deliberative Council, Boston Scientific recommends NO change to clinical follow-up due to this unique event. Specifically for patients with S-ICD systems: • Continue to use the S-ICD system to detect and treat ventricular tachyarrhythmias at risk of death; • Keep LATITUDE ™ programmed and / or in clinical follow-ups; and • Follow the precautions identified in the S-ICD user manual when radiation therapy is prescribed. In addition, Boston Scientific DOES NOT recommend the following: • Early or out-of-cycle follow-up. This type of memory corruption can not be detected, so additional S-ICD checks do not reduce the potential for behavior of this device. • Prophylactic substitution or explant of S-ICD. The risks associated with such an additional surgical procedure significantly outweigh the risk of recurrence of the behavior of this device. Until software mitigation update is available, this S-ICD behavior represents a small additional risk that should be considered when assessing the relative risks associated with all available DCI therapy options. If you wish to notify technical complaints and adverse events use the following channels: Notivisa: Notices of adverse events (AE) and technical complaints (QT) for products subject to Sanitary Surveillance should be made through the NOTIVISA System. To access the System, you must register and select the Health Professional option, if you are a liberal professional or the Institution / Entity option, if you are a professional of an institution / entity. Technovigilance System: Patient or citizen can notify through the Technovigilance System / SISTEC access through the link Additional information: - Date of identification of the problem by the company: 06/30/2017 - Date of notification notice to Anvisa: 06/07/2017 The company that owns the affected product is responsible for contacting its customers in a timely manner. to ensure the effectiveness of the Field Action in progress. It stands out the joint responsibility of the distribution chain and use of health products in maintaining its quality, safety and efficacy, as well as the effectiveness of the Field Action, expressed by RDC 23/2012: "(...) Art 2 ° A holder of registration of health product is the holder of the registration / registration of health product with Anvisa. Single paragraph. The registration holder, as well as other agents involved from the production to the use of the product, or discarding it when applicable, are jointly and severally responsible for maintaining the quality, safety and efficacy of the health products to the final consumer.

  • Reason
    Boston scientific reports on a unique and isolated event with the s-icd pulse generator that resulted in the death of a patient related to the device in may of this year. boston scientific engineers determined that this patient's s-icd repeatedly delivered an atypical amount of energy (similar to the arrhythmia induction function) because a memory location was corrupted by the radiation inside the environment. this repeated delivery of atypical energy avoided the detection / treatment of arrhythmia by s-icd and contributed mainly to the death of the patient. the investigation of the root cause of this event identified a single scenario that might lead to this behavior in an s-icd. boston scientific engineers simulated this scenario by corrupting two adjacent adjacent bits of memory in representative s-icds within a laboratory configuration. the tests demonstrated an energy output similar to the arrhythmia induction function, correlated with the information available from this event. additional simulations were performed in attempts to produce this behavior and no other scenarios were identified. boston scientific concluded that the corruption of the two adjacent memory locations in this event were due to single-event adversity.

    “We take a patient-first approach to assessing the applicability of every recall and communicate to regulatory bodies in all geographies where the recalled device is sold,” Boston Scientific said in a statement to ICIJ. “We have coordinated several recalls across many countries in a timely manner,” the company said, adding that it complies with all national laws, which can often vary and require different processes for reporting information or taking action on recalls. The company said it uses a rigorous and uniform process to take action on recalls and that “when we initiate a field action (e.g. recall, safety alert), every customer who has received an affected product receives a communication that includes a letter for the physician.”
