ELITE: Safety and Performance Study for Arterial Large Hole Vascular Closure Device
Study Details
Study Description
Brief Summary
To study will assess safety and performance of the PerQseal Elite Closure Device when used with the 18F PerQseal Elite Introducer to percutaneously close femoral artery punctures and to induce arterial haemostasis in patients undergoing endovascular procedures requiring an arteriotomy created by 14 to 22 F sheaths.
Note, for reference purposes, it is expected arteriotomies created with 14 to 22 F sheaths will create an arteriotomy in the range of 16 - 26 F (being the outer diameter of these sheaths).

Detailed Description
This study will be a prospective, multi-centred, non-randomized study to investigate the safety and performance of the PerQseal Elite. The study shall not be blinded prior to, during or post the procedure. All patients undergoing an endovascular procedure requiring an arteriotomy created by 14 to 22 F sheaths, via the common femoral artery will be screened against the inclusion/exclusion criteria.
All subjects shall have a pre-discharge, 30-Days ± 7-Days and 180-Days ± 30-Days follow-up assessment. All safety data from the study will be assessed by the Data Safety Monitoring Committee on a continuous basis.

Outcome Measures
Primary Outcome Measures
- Primary Safety Endpoint - Major access site complications [through 30 Days]
Rate of major access site complications attributable to the PerQseal Elite device
- Primary Effectiveness Endpoint - Time to Haemostasis [20 Minutes]
Time to Haemostasis (TTH) defined as elapsed time in minutes from PerQseal Elite (Introducer-sheath and Delivery-device) removal to first observed cessation of common femoral artery (CFA) bleeding, excluding cutaneous or subcutaneous oozing, and in the absence of a developing haematoma.
Secondary Outcome Measures
- Secondary Safety Endpoint - Incidence of Minor Access Site Complications [Through 30 Days]
The Incidence of minor access site complications attributable to the PerQseal Elite device
- Secondary Effectiveness Endpoint - PerQseal Elite Technical Success Rate [10 Minutes]
Defined as the number of PerQseal Elite devices that are deployed and achieve haemostasis (i.e., cessation of arterial bleeding excluding cutaneous or subcutaneous oozing) without need for more than 10 minutes of firm, adjunctive manual compression or alternative treatment (other than adjunctive endovascular ballooning) at target access site, divided by the total number of PerQseal Elite devices where deployment was attempted, within the mITT population
- Secondary Effectiveness Endpoint - PerQseal Elite Treatment Success Rate [through 30 days]
Defined as the number of subjects who meet PerQseal Elite Technical Success without experiencing a device related Major Access Site Complication (based on CEC adjudication) through 30-days, divided by the total number of subjects where PerQseal Elite device deployment was attempted, within the mITT population.
- Secondary Effectiveness Endpoint - Time to Device Deployment [20 Minutes]
Defined as the time from insertion of the PerQseal Elite delivery device into the PerQseal Elite Introducer sheath to complete removal of the PerQseal Elite (delivery device and introducer-sheath) from the subject following PerQseal Elite deployment.
- Secondary Effectiveness Endpoint - Time to Ambulation [through 24 hours]
Defined as the elapsed time from PerQseal Elite removal from the subject post deployment until the subject can walk 20 feet/6 meters without arterial re-bleeding at the target access site. This endpoint will be evaluated only for subjects who are ambulatory (e.g., not confined to wheelchair or bed) at the time of enrolment.
- Secondary Effectiveness Endpoint - Total Closure Time [40 Minutes]
Total Closure Time is defined as: Time to Haemostasis (TTH) plus Time to Device Deployment (TTDD).
