简要总结
The purpose of this study is to evaluate the safety and performance of the MANTA Vascular Closure Device (VCD) to close the arteriotomy following percutaneous cardiovascular procedures utilizing large bore sheaths for purposes of supporting a CE Mark (Conformite Europeenne--"European Conformity") and other regulatory submissions. The study will assess whether the MANTA VCD is safe and performs as intended for large-bore vascular closure after interventional procedures.
详细描述
The purpose of this study is to evaluate the safety and performance of MANTA in achieving hemostasis in femoral arterial access sites in patients undergoing percutaneous transcatheter interventional procedures using a 10-18F procedure sheath (such as Transcather Aortic Valve Replacement (TAVR), Balloon Aortic Valvuloplasty (BAV) and Endovascular Aneurysm Repair (EVAR)) for purposes of obtaining a CE Mark in the European Union.
The study will evaluate hemostasis success, time to hemostasis and ambulation, treatment success, and the rate of access-site-related complications in comparison to published literature on other hemostasis techniques for closing these large bore punctures (primarily, surgical closure and suture-mediated percutaneous closure.

入选标准
- •Candidate for non-emergent transcatheter interventional procedure via a 10-18F femoral sheath (e.g., transcatheter aortic valve replacement [TAVR], balloon aortic valvuloplasty [BAV], Abdominal Aortic Aneurysm [AAA] stent-graft placement)
- •Eligible for sheath removal in the catheterization lab
- •Age ≥18 years
- •Understand and sign the study specific written informed consent form
- •Able and willing to fulfill the follow-up requirements
- •In the Investigator's opinion, the patient is suitable for the MANTA vascular closure device, conventional hemostasis techniques and participation in an investigational trial

研究组 & 干预措施
MANTA Vascular Closure Device
The MANTA device, developed by Essential Medical, Inc., is a vascular closure device (VCD) intended for use in catheterization laboratories following percutaneous cardiac or peripheral procedures that use the retrograde common femoral artery access route for large bore (10-18F) interventional devices.

结局指标
主要结局
Number of Participants With Major Complications
时间窗: Within either the first 30 days (plus or minus 7 days) after the procedure or the first 60 days (plus or minus 14 days) after the procedure
Composite endpoint that includes any of the following adverse events: * Access site-related bleeding requiring blood transfusion or vascular repair * Vascular injury requiring repair (e.g. perforation, dissection, arterio-venous fistula, retroperitoneal bleed, pseudoaneurysm) * Femoral artery stenosis at the access site requiring intervention * New ipsilateral lower extremity ischemia causing a threat to the viability of the limb * Access site-related infection requiring intravenous antibiotics and/or extended hospitalization * New onset access site-related neuropathy in the ipsilateral lower extremity requiring surgical repair * Permanent access site-related nerve injury (lasting\>30 days)
Hemostasis Success
时间窗: Within the first 10 minutes of cutting the MANTA suture
Hemostasis at the puncture site within 10 minutes of cutting the MANTA suture without need for manual or mechanical compression and without later re-bleeding (trivial or subcutaneous oozing will not be considered bleeding; light finger pressure to control subcutaneous oozing will not be considered manual compression)
次要结局
- Time to Hemostasis(Time between MANTA deployment and first observed and confirmed arterial hemostasis up to ten (10) minutes after MANTA device is deployed.)
