(b)(4).The device was not returned for evaluation.The investigation determined the reported balloon rupture and failure to deploy stent appears to be related to circumstances of the procedure.It should be noted that the absorb, instructions for use (ifu) states: it is not recommended to treat patients having a lesion that prevents complete inflation of an angioplasty balloon, or a lesion with greater than 40% residual stenosis after predilatation by visual estimation.A review of the lot history record (lhr) revealed no manufacturing nonconformities that would have contributed to this complaint.Additionally, a review of the complaint history identified no similar incidents from this lot.It should be noted that the ifu, instructs the physician to: note the product use-by (expiration) date on the package.Based on the information reviewed, there is no indication of a product quality issue with respect to manufacture, design or labeling.The absorb device is currently not commercially available in the u.S.; however, it is similar to a device sold in the u.S.

It was reported that the procedure was to treat a heavily calcified lesion in the mid left anterior descending (lad) artery.Pre-dilatation was done, but due to the calcification, the lesion could not be optimally prepped and more than 40% residual stenosis remained.The 2.5 x 23 mm absorb was advanced to the lesion, but the balloon ruptured during first inflation at nominal pressure.The delivery catheter was removed with the stent still crimped on the balloon.The procedure was successfully completed with a non-abbott drug eluting stent.There was no clinically significant delay in procedure and no adverse patient effects.No additional information was provided.
