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.

Outcomes
Primary outcome [1] 318866 0
Safety:
Incidence of 30-day MACCE or Stage 3 acute kidney injury assessed through clinical examination, self-reported symptoms, and medical record review.
Timepoint [1] 318866 0
Safety to 30 days post procedure.
Primary outcome [2] 318867 0
Performance:
Defined as the ability to successfully access the aortic arch, position across the aortic arch and retrieve the Emboliner as reported by the investigator.
Timepoint [2] 318867 0
Immediately post procedure.
Secondary outcome [1] 366287 0
Incidence of in-hospital investigational device-related serious adverse events such as:
Air embolism
Introduction of catheter particulate matter
Allergic reaction to the device or study materials
Infection
Acute thrombosis or inflammatory response
Ischemic stroke or TIA
Aortic dissection or perforation
Mural thrombus formation
Access site complications

To be assessed by the study investigator and hospital staff through standard patient care and clinical assessment post TAVR. In adddition, the subject's medical records will be reviewed by the study monitors to understand medical history and any changes that might indicate the occurrence of an SAE post treatment.


Timepoint [1] 366287 0
To hospital discharge.
Secondary outcome [2] 366288 0
Incidence of investigational device-related serious adverse events at 30 days:

Air embolism
Introduction of catheter particulate matter
Allergic reaction to the device or study materials
Infection
Acute thrombosis or inflammatory response
Ischemic stroke or TIA
Aortic dissection or perforation
Mural thrombus formation
Access site complications

To be assessed by the study investigator and hospital staff through standard patient care and clinical assessment post TAVR. In adddition, the subject's medical records will be reviewed by the study monitors to understand medical history and any changes that might indicate the occurrence of an SAE after hospital discharge through the 30 day study contact.

Timepoint [2] 366288 0
To 30 days post procedure.

Statistical methods / analysis
The number and percentage of patients who experience any of the pre-defined 30-day MACCE (consisting of death, stroke and Stage 3 AKI) will be presented. The 30-day MACCE data will be compared against a historical control MACCE rate of 12% from representative TAVR trials as described in Emboline engineering memo EM-0426, Historical MACCE Rates.

The number and percentage of patients in whom the device achieved technical success will be presented. Performance data will be reported by patient.
