  • Reason
    Boston scientific corporation received 16 reports distributed in n = 5 of slow deflation and = 11 non-deflation for the 20,000 units of talon product distributed worldwide since the product was introduced in the market five years ago. twelve of these incidents were reported by customers in japan in 2005. likewise, 6 slow-deflation events and 3 non-deflation events were reported for the symmentry product, which has 92,000 units distributed worldwide since its introduction which occurred 5 years ago, were all reported in japan and 7 of them occurred in 2005. in all reported cases the balloons were fit to be deflated by traditional standard methods. none of the patients required medical intervention to remove the balloon. in none of the cases there was an adverse event, complications and extension in the procedure time. investigations of these reports by boston scientific corporation revealed that in at least 3 of the cases, the balloon catheter was intentionally inflated to more than 3 atmospheres ("atm") above the recommended maximum burst pressure ("rbp"). balloon rupture)) as described in the instructions for use of the product. not enough information was available to determine if the balloons were over-inflated in other cases. analyzes of a failed product unit determined the potential cause of the collapse of the thin wall material (crevice) at the tip interface and the inner lumen of the catheter wall. this may have prevented the exit of the insufflation solution from the balloon.
  • Action
    In order to thoroughly investigate the cause of these slow-deflating and non-deflating events, Boston Scientific Corporation conducted an engineering study in which the Talon and Symmetry product balloons were repeatedly inflated to RBP (15 atm) and deflated according to instructions contained in the Instructions for Use. All products tested passed the disinflation / inflation test according to the criteria of the product specification.
