Clinical Study of the Medeon Biodesign XPro™

To access the safety and performance of the XPro System to facilitate hemostasis in patients undergoing percutaneous endovascular procedures utilizing 8-18 Fr introducer sheath via the common femoral.

This is a prospective multi-center, single arm study to assess the safety and performance of the XPro System compared to a historical control developed from published studies of two marketed competitive devices, Perclose ProGlide® and Prostar® XL (both from Abbott Vascular, Inc., Redwood City, CA, USA). The goal of the study is to show that XPro System is non-inferior to the competitors in efficacy and safety. Patients scheduled for percutaneous BAV, TAVR/TAVI, EVAR, or TEVAR procedures using an 8-18 Fr introducer sheath will be screened for study eligibility. Patients will be followed for 30 days post procedure.

Eligibility Criteria:
Inclusion Criteria:

* Patient is \> 18 years old
* Patient is scheduled for percutaneous BAV, TAVR/TAVI, EVAR, or TEVAR involving access through the femoral artery using an 8-18 Fr introducer sheath
* Patient is able to undergo emergent vascular surgery if a complication related to the vascular closure necessitates such surgery
* Patient, or authorized representative, signs a written Informed Consent form to participate in the study, prior to any study mandated procedures
* Patient is willing and able to complete follow-up

Exclusion Criteria:

* Prior intra-aortic balloon pump at access site
* Patients with severe claudication, iliac or femoral artery diameter stenosis greater than 50%

* Access site above the most inferior border of the inferior epigastric artery (IEA) and/or above the inguinal ligament based upon bony landmarks
* Access site in the profunda femoris or superficial femoral arteries, or the bifurcation of these vessels
* Ipsilateral femoral venous sheath during the catheterization procedure
* Common femoral artery calcium, which is fluoroscopically visible
* Patients where there is difficulty inserting the introducer sheath or greater than 2 ipsilateral arterial punctures at the start of the catheterization procedure
* Difficulty in obtaining vascular access resulting in multiple arterial punctures and/or posterior arterial puncture
* Evidence of a pre-existing hematoma, arteriovenous fistula, or pseudoaneurysm at the access site
* Patients with intra-procedural bleeding around access site
* Evidence of active systemic or local groin infection
* Patients receiving glycoprotein IIb/IIIa inhibitors during, or after the catheterization procedure
