Manufacturer Narrative

Device is not accessible for testing as it remained implanted in the patient.A review of the complaint device history records, indicated that the graft was processed and inspected according to established procedures and was therefore released following acceptable quality inspections and tests.Specifically, no anomaly was evidenced in the collagen coating records.Moreover, the review of the water permeability testing records of products coated on the same day as the complaint device indicated values well within product specifications (< 5 ml/cm²/min).One retention sample coated on the same day and under the same conditions as the involved device underwent water permeability testing.The test result indicated a value well within product specifications (< 5 ml/cm²/min).The review of post-marketing historical data indicated that no other similar complaint was reported for the same product family and the same lot number.A video of the surgery was provided by the user, showing evidence of the blood leakage.A review by our corporate medical officer is pending.The investigation is still ongoing.A follow-up report will be sent upon completion of the investigation.

Event Description

The customer reported that the graft was bleeding during surgery.He mentioned spots where there was discrete bleeding along the length of the graft.It required the application of surgical sealant (coseal) to try to minimize blood loss.A video is available.

Manufacturer Narrative

(4112/213) a video of the surgery was provided by the user, showing evidence of the blood leakage.Below is the assessment of our corporate medical officer: "the complaint describes the use of an intergard woven graft sutured to, what i assume from the video provided, is the subclavian artery for a post-cardiotomy circulatory assistance.The graft was tunneled through the chest wall and connected with the circuit's arterial line with several silk tights.From the video provided, a minimal oozing from the graft can be observed in few very limited areas of the graft.The procedure was completed using the same graft and with the application of a surgical sealant.Intergard woven grafts are not indicated for arterial cannulation during circulatory assistance.The minor graft oozing observed could be due to several causes.The graft manipulation required to tunnel it through the chest and the high flow to which the graft is subjected are among the most important factors.The amount of oozing seen in the video should be considered expected for this type of application." (67) the conducted investigation and testing performed suggest that the product was not defective at the time of manufacturing.(24) please note that, as per the product instructions for use, the use of an intergard woven graft as a conduit for cannulation is not an approved indication.Indeed, intergard woven vascular grafts are indicated for surgical repair, bypass, or replacement of arteries in the treatment of aneurysmal and occlusive disease of the aorta, both thoracic and abdominal, visceral arteries, and proximal peripheral arteries.
