8. Known existing nerve damage in the target leg,
9. Renal insufficiency (Glomerular Filtration Rate ≤ 30 ml/min or baseline serum creatinine > 2.5 mg/dL) or on renal replacement therapy,
10. Known allergy to any of the materials used in the PerQseal device (refer to Instructions for Use),
11. Subject unsuitable for surgical repair of the target leg access site,
12. Subject has undergone a percutaneous procedure greater than 8 F sheath in the target leg, within the 90-days prior to index procedure,
13. Subject has undergone a percutaneous procedure of 8 F sheath or less using an absorbable intravascular closure device for haemostasis, in the target leg, within the 90-days prior to index procedure,
14. Subject has undergone a percutaneous procedure of 8 F sheath or less using a suture mediated closure device or manual/mechanical pressure for haemostasis in the target leg, within the 30-days prior to index procedure,
15. Evidence of marked tortuosity of the femoral or external iliac arteries in the target leg, based on pre-primary procedure CT angiography,
16. Evidence of arterial diameter stenosis > 30% within 15 mm proximal or distal to arteriotomy site based on pre-primary procedure CT angiography,
17. Evidence of anterior wall calcification of the target common femoral artery (other than small, diffuse deposits which in the opinion of the investigator will not impede the vascular closure procedure) within 15 mm proximal or distal to arteriotomy site based on pre-primary procedure CT angiography,
18. Target femoral artery diameter is less than 6 mm or 7 mm, depending on whether S (small) or L (large) PerQseal Introducer will be used for arteriotomy closure, respectively, based on pre-primary procedure CT angiography,
19. Further planned endovascular/catheter-based procedure in the target leg in the 30-days following the index procedure.
20. Subject is enrolled in another investigational medical device or drug study,
21. Subject has been previously enrolled in this clinical study.
22. Current COVID-19 infection (with or without symptoms), recent positive test for COVID-19 within two weeks, or recent exposure to a person with COVID-19 infection within two weeks.

Procedural Exclusion Criteria:

23. If any Procedural Exclusion Criteria listed below are met, then closure with PerQseal device is not permitted.
24. Initial common femoral arterial access achieved with manual palpation or blind arterial stick access, without use of an image guided approach (ultrasound or angiography).
25. Difficult dilation during initial target femoral artery access (e.g., that damages or kinks dilators) while step-dilating up to the large-bore device,
26. During arterial puncture, the target femoral artery suspected to have experienced a posterior arterial wall needle puncture or underwent > one needle puncture during the primary procedure (with a needle larger than a Micropuncture needle (> 21 gauge or > 0.819 mm diameter) )
27. Subject has a tissue tract (i.e., estimated distance from skin entry point to arterial anterior surface at arteriotomy) expected to be greater than 8 cm.,
28. Significant blood loss requiring transfusion of blood products during primary procedure or within 30-days prior to index procedure,
29. Activated clotting time (ACT) > 250 seconds immediately prior to sheath removal or if ACT measurements are expected to be > 250 seconds for more than 24 hours after index procedure,
30. Target puncture site is in a vascular graft,
31. Target arteriotomy greater than 26 F,
32. Target arteriotomy in the profunda femoris or superficial femoral artery or is in common femoral artery, but within 15 mm proximal of the bifurcation of the superficial femoral/ profunda femoris artery,
33. Target arteriotomy located at the level or above the inferior epigastric artery and/or beneath or above the inguinal ligament based on bony/arterial landmarks (above femoral head on A-P projection),
34. Subjects with an acute haematoma > 4 cm diameter, arteriovenous fistula, pseudoaneurysm, or intraluminal thrombosis at the target access site identified intra-procedurally,
35. Evidence of bleeding around the primary procedure sheath (VARC type1/BARC type 2 or higher),
36. Intra-procedural angiographic evidence of arterial laceration, dissection or stenosis within the femoral artery that would preclude use of the PerQseal device,
37. Uncontrolled hypertension (systolic blood pressure > 180 mmHg or diastolic blood pressure > 110 mmHg) at the time of planned vascular closure,
38. Systolic blood pressure < 90 mmHg at the time of planned vascular closure.
