This report is being submitted as follow up no.1 to provide additional information in section b5, to update section h3, and to provide the completed investigation results.One 90 cm 6fr destination was returned for product evaluation.Visual inspection revealed that there was damage noted along the sheath.The sheath was flattened from 29cm to 41 cm from the hub.The sheath shaft was inspected under microscope and there were several scratches noted along the sheath and the flattened portion was imprinted with an unknown patterned.The tip of the sheath was viewed under a microscope and a small tear was noted.Based on the provided information and investigation results, there is no definitive evidence that this event was related to a device defect or malfunction.The exact cause of the reported event cannot be definitively determined based on the available information.

Additional information was received on (b)(6)2020.Resistance was felt during insertion or withdrawal of sheath.The dilator could not be inserted inside the sheath.No damage was noted before sheath insertion however, the when the sheath was removed and replaced with another sheath the damage was noted.A new 7 fr 90 cm destination sheath was used and the dilator was inserted in the sheath.The physician's note, comments and observations stated the following: "the patient's abdominal aorta was widely patent with no obvious flow limiting lesions.The patient's renal arteries bilaterally were widely patent with no flow limiting lesions.The patient did have some mild stenosis of the right common iliac artery but did not appear to be flow limiting.Left common iliac artery is widely patent and the right was entirely normal.Left cfa had a high grade stenosis of questionable significance, bilateral hypogastric arteries were patent.Bilateral external iliac arteries were patent, and the right was entirely normal.Left cfa had a high grade stenosis of questionable significance.Bilateral profunda femoris were widely patent with no flow limiting lesions.Bilateral sfas were widely patent with sporadic diseases throughout of questionable significance.There does not appear to be any flow limiting lesions in the sfa.Bilateral popliteal arteries were widely patent with not flow limiting lesions.Anterior tibial artery was patent proximally and then occluded for short segment in its upper third portion and then reconstituted.The right posterior tibial artery had a high grade 95% stenosis at its origin, and the remainder of the vessel was free of any diseases with a direct in line blood flow to the end of the foot.Incomplete pedal arch foot.The patient's tibial peroneal trunk was occluded on the right side with collateral filling the peroneal artery." the operative notes stated the following: "the patient was taken to the deaconness cardiac cath lab in evansville, in, and placed in the supine position on the table.After adequate sterile prep and drape, a time-out was taken.Next, lidocaine was used to anesthetize the skin in the left groin.A micro puncture technique was used to gain access to the left cfa in retrograde fashion.A 5 fr short sheath was placed.There was some plaque identified in the cfa on the left side.Next, a stiff guidewire was then used to place an omniflush catheter at level t12 and an aortagram was obtained.I then withdrew the omniflush cath to the level of the bifurcation and completed the run-off.A french 90 cm sheath was then placed with the assistance of the omniflush cath to gain contra iliac access, and the sheath was placed with fluoroscopic guidance.Right lower extremity angiogram was obtained from the right popliteal artery using a 6 fr 90 cm sheath with hand injection of 10 cc of half and half contrast.I then used an 0.014 command wire to try and recanalize the at without success.I remained in the subintimal place and was unable to re-enter.Therefore, i did abort this, and focused on the pt.After about 45 minutes worth of effort i was able to finally get a wire down through the proximal (b)(4) stenosis and balloon angioplastythe right pt with a 3 x 300 balloon.Final angiogram revealed excellent flow to the pt.The patient does have single vessel run-off into the foot via the pt.He has excellent would healing potential even with the incomplete arch.If the patient does not heal, i recommend a retrograde right dorsalis pedis approach to recanalize the at.We will see him back in three weeks in the office for follow up.I did do a sheath shot in the groin before leaving, and it looked like a good stick.Of note, when i did remove the 690 sheath i did have to pull in it a little bit more than usual, and i noticed that the sheath was flattened upon removal.The patient remained hemodynamically significant throughout the case, and i cannot account for the flattening of the sheath or the difficulty removal around the bifurcation.We will watch this patient closely as he is an inpatient.The patient tolerated the procedure well.".
