Boston Scientific has identified a tooling error in manufacturing which may have caused delamination of the inner lumen of the sheath shaft in a subset of POLARSHEATH devices. This could result in the embolization of a fragment during use (such as flushing of the sheath or introduction of the dilator or ablation catheter).
Teleflex is initiating this voluntary recall for the above-mentioned products due to reports received indicating a potentially defective component. The complaints received relate to resistance of the guidewire handle/chamber during use. The possible immediate health consequences of the component issue are arterial vasospasm and vessel injury arising from multiple arterial punctures with repeated attempts.
