(b)(4).During processing of this complaint, attempts were made to obtain complete event, patient and device information.Absorb scaffold implanted in a vessel less than 2.5mm diameter.The scaffold remains in the patient.Investigation is not yet complete.A follow up report will be submitted with all relevant information.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 on (b)(6) 2015 was to treat a lesion located in the proximal left anterior descending (lad) artery with 79% eccentric stenosis.Vessel sizing was performed with angiography and determined that the vessel was less than 2.5mm.Predilatation was performed with a 2.5x20mm non-abbott balloon at 10 atmospheres (atm), resulting in 59% residual stenosis.A 2.5x28mm absorb was implanted followed by post-dilatation with a 2.5x15mm non-abbott high pressure balloon at 20 atm.No imaging was performed to confirm the absorb scaffold was fully apposed to the vessel wall.The patient returned on (b)(6) 2015 for a regular follow-up and was prescribed plavix and aspirin for three months per protocol.On (b)(6) 2018, the patient presented with angina and the absorb scaffold was identifed with restenosis and was treated with the implantation of a xience stent.The patient was confirmed to have been compliant with their dual anti-platelet therapy.The final patient outcome was good with timi 3 flow.No additional information was provided.

(b)(4).There was no reported device malfunction and the product was not returned as the scaffold remains in the anatomy.A review of the lot history record and complaint history of the reported device could not be conducted because the lot number was not provided.The reported patient effects of angina and restenosis, as listed in the bioresorbable vascular scaffold (bvs) system, absorb, instructions for use are known adverse events associated with the use of a coronary scaffold in native coronary arteries.Based on the case information, a conclusive cause for the reported patient effects, and the relationship to the product, if any, cannot be determined.There is no indication of a product quality issue with respect to design, manufacture or labeling of the device.
