This study evaluates the safety and performance of the Ladera Medical suture-mediated large bore closure (LBC) system in gaining post procedure hemostasis in subjects undergoing interventional catheterization procedures using a large-bore procedure sheath.

The Ladera Medical suture mediated large bore closure (LBC) system is a vascular closure device intended for use in catheterization laboratories following percutaneous interventional catheterization procedures that use the retrograde common femoral artery access route for large bore interventional devices. The function of Ladera LBC System is to percutaneously close the puncture in the artery wall (arteriotomy) through which the catheters were inserted for the procedure.

The study is being conducted to demonstrate the safety and performance of the LBC System in achieving hemostasis in femoral arterial access sites in subjects undergoing percutaneous interventional catheterization procedures using a large-bore procedure sheath.

Inclusion Criteria:

1. Patient is ≥ 18 years old
2. Patient is scheduled for elective or planned (i.e., not emergent or urgent) percutaneous interventional catheterization procedures involving access through the common femoral artery using 10 to 24 Fr introducer sheaths (i.e., BAV, TAVR/TAVI, PEVAR, TEVAR)
3. Patient is able to undergo emergent vascular surgery if a complication related to the vascular closure necessitates such surgery
4. Patient is willing and able to complete follow-up requirements
5. Patient has the mental capacity to consent for themselves (i.e., does not require the use of a Legally Authorized Representative), and signs a written Informed Consent Form (ICF) prior participating in the study

Exclusion Criteria:

Patients must be EXCLUDED from participation in this study if ANY of the following criteria are met:
