To evaluate the safety and effectiveness of direct carotid access for stenting using
the Neuroguard IEP® Direct System in subjects at elevated risk for adverse events
following carotid endarterectomy (CEA).

Patients with large abdominal aortic aneurysms (AAA) (>5.5cm) are recommended to have surgery, but there is no therapy for small AAA (3-5cm). The purpose of this study is to collect ultrasound images and blood from patients with normal abdominal aorta as well as from patients with small AAA. Study participants include patients scheduled for an aortc ultrasound aorta and may fall into one of these categories. By analyzing the aortic wall ultrasound images and the blood levels of particular proteins, we hope to identify a target for drug therapy to stop AAA growth. Voluntary participation in this study does not change the original intent of the ultrasound and does not change patient treatment. The pictures gathered here are in addition to the standard ultrasound and cause no additional risk. Participation would include the standard aorta ultrasound, specific extra pictures (less than 5 minutes to collect), and collection of a blood sample. If a participant's aorta is within normal limits, no additional ultrasound visits or study visits will be indicated. If the participant has a small AAA, standard of care would be to return once per year for repeat ultrasound. Ongoing participation in the study will be to have the extra ultrasound images captured and repeat blood sampling, for a total of 3 years.

The purpose of this registry is to collect safety data in patients undergoing aortic aneurysm repair, peripheral vascular intervention, hemodialysis access intervention or peripheral embolization with an eligible Medtronic market-released product(s), including but not limited to balloon catheters, peripheral or carotid stents, stet grafts, and coils, in a real-world setting.

This is a study comparing the new class anticoagulants factor XIa to the FDA approved Apixaban. The study is to determine if Milvexian is as effective and safe with preventing clots for patients with A-fib and to determine if Milvexian is better at reducing the chances of bleeding.

This study is for patients that have Critical Limb Ischemia (CLI), a form of Peripheral Arterial Disease (PAD) in which an artery (blood vessel) in their lower leg (calf) may have become blocked. This study involves the use of an investigational devices called a stent (a small mesh tube typically used to hold open blood vessels). The study device (stent) that will be used in this study is called the Bare Temporary Spur Stent System. It is intended to be used for treatment of Critical Limb Ischemia (CLI). The stent portion is made of nitinol, a metal commonly used in stents. It is unique from other similar approved devices, such as balloons and stents, because it consists of a delivery system that can deliver and re-capture the Bare Temporary Spur Stent and balloon, so that no metal is left behind in the body. The Bare Temporary Spur Stent has small spurs (spikes) on the outer surface of the stent, which pierce the inner lining of the artery. Together, the spurs and the stent may help to support the artery as it rebounds after the balloon inflation. The purpose of this is to help the artery stay open so that there is a channel for blood flow to the foot.

The study is to evaluate real world usage of the ENROUTE® Transcarotid Stent System when used with the ENROUTE® Transcarotid Neuroprotection System in patients with significant carotid artery disease who are at standard risk for adverse events from carotid endarterectomy (CEA). The devices used in the study are not investigational and have been approved for use by the Food and Drug Administration (FDA).

The purpose of this research study is to find out if AMDS is safe and effective in the treatment of acute dissection (sudden tear). For patients whose aortic anatomy is suitable for treatment with AMDS, the use of this device may promote healing of the aortic walls and possibly reduce the need for additional aortic surgeries. If conventional surgery, in combination with AMDS, is effective, it is believed that this could lead to improved aortic healing; an improvement in healing could reduce the risk of hospitalization and reoperation in the chest compared to conventional surgery alone.

The types of balloons being studied in this clinical study is similar to other balloon devices that are routinely used in angioplasty procedures; however, it has a unique technology inside the balloon which is designed to deliver sonic energy (sound) to disrupt the hard, calcified elements of vascular blockages. With the balloon inflated at a low pressure, the probe will be activated to disrupt the calcium that is restricting the expansion of the artery.

This study will compare WATCHMAN FLXTM ("DEVICE") to a category of OAC called non-vitamin K antagonist oral anticoagulation, also known as NOACs ("CONTROL"). NOAC medications include Pradaxa® (dabigatran), Eliquis® (apixaban), Xarelto® (rivaroxaban), or Savaysa® (edoxaban).The study will research the safety and effectiveness of the WATCHMAN FLXTM device compared to treatment with NOAC therapy to determine if it works for patients with your type of atrial fibrillation who require treatment for potential blood clot formation (thrombus) in the LAA.
