Description of intervention(s) / exposure
The EmbolinerTM embolic protection catheter, manufactured by Emboline, Inc., is a temporarily-implanted aortic embolic filter for use during interventional cardiology procedures, such as transcatheter aortic valve replacement (TAVR). The Emboliner system consists of a single-use, sterile, heparin-coated Nitinol filter attached to a catheter, a delivery/retrieval sheath and dilator, a peelaway inserter, and a braid loading tool. The Emboliner is introduced through a femoral access site using the included delivery sheath and dilator. In TAVR procedures, the contralateral access site is used. The filter of the Emboliner is deployed across the aortic arch to prevent embolic debris that are generated during the procedure from reaching the cerebral circulation, and other vulnerable areas of the body. The integrated 6-Fr compatible lumen of the Emboliner catheter allows guidewires and diagnostic catheters to be introduced through the Emboliner during the procedure. The expandable access port of the Emboliner allows passage of catheters and delivery systems through the filter during the procedure. The use of the Emboliner device is expected to add minimal time to the overall TAVR procedure (approximately 15-30 minutes). The Emboliner device is used by the interventionalist performing the TAVR Procedure. At the end of the interventional procedure, the Emboliner is retrieved by withdrawal into the delivery/retrieval sheath, which is then removed from the body.

Summary
Brief summary
A known complication of TAVR and similar procedures is the dislodging of embolic particles. Those particles may include blood clot, valvular tissue, or foreign material such as calcium. Once these particles have entered the bloodstream, it is possible that they might travel to the brain and cause neurological problems or stroke; or they may travel to other parts of the body, such as the kidneys, and cause damage; or they may lead to death.

The device being investigated in this study, the Emboliner embolic protection catheter, is a temporarily-implanted aortic embolic filter for use during cardiology interventions. The filter of the Emboliner is intended to stop these dislodged particles (embolic particles) from entering the bloodstream and travelling to other parts of the body. It is made of a metal called nitinol and is coated with a medication (heparin) that helps to prevent blood clotting on the device. The Emboliner is positioned in the aorta and is expanded so that it fits snuggly against the wall of the aorta. It is designed to filter the blood and capture any embolic particles. The device is then able to be retrieved and removed from the body, along with any embolic particles that may have been collected.

The objective of study is to evaluate the safety and performance of the Embo-liner embolic protection catheter.
