• •12. Evidence of marked tortuosity of the femoral or external iliac arteries in the target leg, based on pre-primary procedure CT angiography
• •13. Evidence of arterial diameter stenosis (greater than 30%) within 15 mm proximal or distal to arteriotomy site based on pre-primary procedure CT angiography
• •14. 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
• •15. Prior target artery closure with any closure device within 90 days prior to the primary procedure, or closure with manual/mechanical compression within 30 days prior to the primary procedure

• •17. Known existing nerve damage in the target leg
• •18. Unsuitable for surgical repair of the target leg access site
• •19. Connective tissue disease (e.g., Marfan's Syndrome), or significant scarring of the target access site which in opinion of the Investigator, would preclude use of the investigational device in accordance with the IFU
• •20. Recent (within 60 days) cerebrovascular accident or Q-wave myocardial infarction
• •21. Morbidly obese or cachectic (BMI greater than 40 kg/m2 or less than 20 kg/m2)
• •22. Planned major intervention or surgery, including planned endovascular/catheter-based procedure, in the target leg in the 30 days following the primary procedure
• •23. Ipsilateral or contralateral lower extremity amputation
• •24. Non-ambulatory (confined to bed or wheelchair)
• •25. Known allergy to any of the materials used in the LBC System (refer to Instructions for Use)
• •26. Pregnant, lactating, or planning to become pregnant within 30 days following the primary procedure
• •27. Would refuse blood transfusion if it were to be needed
• •28. Current enrollment in another investigational medical device or drug study
• •29. Previous participation in this study
• •30. Other medical, social, or psychiatric condition that in the opinion of the Investigator would interfere with participation in the study
• •Intra-Procedural
• •1. Access site tissue tract (i.e., estimated distance from skin entry point to arterial anterior surface at arteriotomy) expected to be greater than the indicated maximum
• •2. Initial common femoral arterial access for the primary procedure achieved with manual palpation or blind arterial stick access, without use of an image guided approach (ultrasound or angiography)
• •3. During arterial puncture for the primary procedure, the target femoral artery suspected to have experienced a posterior arterial wall needle puncture or need for greater than 2 ipsilateral arterial punctures
• •4. Primary procedural access site in the profunda femoris or superficial femoral artery or the bifurcation of these vessels
• •5. Primary procedural access site located at the level or above the inferior epigastric artery and/or above the inguinal ligament based on bony/arterial landmarks (above femoral head on A-P projection)
• •6. Difficult dilation during initial target femoral artery access (e.g., that damages or kinks dilators) while step-dilating up to the primary procedural sheath
• •7. Primary procedural access site is in a vascular graft
• •8. Primary procedural sheath ID greater than the indicated size, or primary procedural device greater than the indicated size if an expandable sheath is used
• •9. Significant blood loss requiring transfusion of blood products during primary procedure
• •10. Evidence of overt, actionable bleeding around the primary procedure sheath
• •11. Primary procedure sheath in place longer than 6 hours
• •12. Evidence of an acute hematoma (greater than 2 cm in diameter), arteriovenous fistula, pseudoaneurysm, or intraluminal thrombosis at the primary procedure access site
• •13. Angiographic evidence of laceration, dissection or stenosis in the femoral artery that would preclude use of the investigational device
• •14. Ipsilateral femoral venous sheath during the primary procedure
• •15. Activated clotting time (ACT) greater than the target immediately prior to primary sheath removal and planned vascular closure or if ACT measurements are expected to be greater than the target seconds within 24 hours after primary procedure
• •16. Uncontrolled hypertension (systolic blood pressure greater than the systolic maximum or diastolic blood pressure greater than the diastolic maximum) at the time of primary sheath removal and planned vascular closure
• •17. Systolic blood pressure less than the systolic minimum at the time of primary procedural sheath removal and planned vascular closure
