The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Key exclusion criteria
Baseline

1. Evidence of current systemic bacterial or cutaneous infection, including groin infection
2. Known bleeding disorders including thrombocytopenia (platelet count < 100,000), thrombasthenia, hemophilia or Von Willebrand's disease or known Type II heparin-induced thrombocytopenia
3. Thrombolytics (e.g., streptokinase, urokinase), Angiomax (bivalirudin) or other thrombin-specific anticoagulants planned within 24 hours prior to primary procedure
4. Glycoprotein IIb/IIIa inhibitors planned within 24 hours prior to the primary procedure, during the procedure, or within 48 hours after the primary procedure
5. Planned anticoagulation therapy within 24 hours after the primary procedure such that the activated clotting time (ACT) is expected to be elevated greater than 250 seconds
6. Significant anemia (hemoglobin less than 9 g/dL or hematocrit less than 27%)
7. Significant blood loss requiring transfusion of blood products within 30 days prior to primary procedure
8. Documented left ventricular ejection fraction less than 20%
9. Renal insufficiency (glomerular filtration rate less than 30 ml/min or baseline serum creatinine greater than 2.5 mg/dL) or on renal replacement therapy
10. Significant inflow disease (iliac or artery diameter stenosis greater than 50%) and/or severe peripheral arterial disease (Rutherford Category 5 or 6), as confirmed with pre-primary procedure CT angiography
11. Common femoral artery lumen diameter less than the indicated minimum based on pre-primary procedure CT angiography
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
16. Prior atherectomy, stent, vascular surgery, or vascular graph in the common femoral artery of target leg
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
