In February, Boston Scientific initiated a recall for its Obsidio Conformable Embolic device, a product designed to block blood flow in target vessels. This recall was driven by reports of seven injuries and two deaths associated with the product’s use. Originally, the Obsidio device was noted for its capability to act like a liquid under force, turning into a soft solid once the force was removed, effectively blocking the intended blood vessels. This quality was particularly valued for its potential applications in managing emergency situations like gastrointestinal (GI) bleeding.
However, complications arose shortly after the product, developed by Obsidio—a company acquired by Boston Scientific in 2022—received FDA authorization. Despite its innovative design, Boston Scientific and medical professionals noticed unintended consequences when Obsidio was used in the GI area using specific techniques. Initially, these adverse effects were primarily associated with the use of the aliquot technique during lower GI treatments. In response to emerging evidence of these risks, Boston Scientific discouraged this specific application method in February.
Further evaluation led Boston Scientific to discover additional risks associated with using Obsidio for any GI bleeding treatment. Updated findings showed that the device could potentially lead to off-target embolization—where the blocking agent moves and affects unintended areas. This could result in diminished blood and oxygen flow to vital organs, potentially necessitating additional medical interventions like bowel resection or colostomy, extended hospital stays, or in severe cases, death.
Boston Scientific responded to these findings by revising the instructions for the use of Obsidio. Updated guidelines now advise against using the aliquot technique or pushing the device with saline during embolization procedures for any GI bleeding. The company stressed the importance of avoiding forceful injections into or near the embolic agent, as this could alter its properties and elevate the risk of inadvertently blocking off-target vessels.
The FDA, which initially posted a Class I recall notice in April, has been actively involved in communicating these updates to ensure patient safety. The latest notice from the agency reflects an increase in the reported impact of these issues, with the total reaching 15 injuries and four deaths. This updated information follows Boston Scientific’s improved guidelines and recommendations for healthcare professionals, which underscore adherence to the revised procedures to mitigate the risk of complications.
Overall, Boston Scientific’s ongoing efforts to refine the use instructions for Obsidio reflect a commitment to patient safety amid challenges encountered in the practical application of this innovative medical device. The updated guidelines and continuous monitoring are crucial steps in addressing the complexities of medical device management and ensuring that the benefits of such technologies are realized without compromising health outcomes.
