Summary

This study will be a prospective, multi-centred, non-randomized study to investigate the safety and performance of the PerQseal® + in up to 90 patients in up to 8 European investigational sites. The PerQseal® + shall be indicated for the percutaneous closure of femoral artery punctures and to induce arterial haemostasis in patients undergoing endovascular procedures requiring an arteriotomy created with 14 - 22F sheaths (arteriotomy up to 26 F).

Description

The study will be designed to be a phased study with an initial enrolment of 25 subjects in phase 1. An interim analysis may be performed after phase 1 and the remainder (up to 65 subjects) may be enrolled as part of phase 2.

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. If the patient meets the requirements of the clinical investigation, they shall be invited to participate, provide informed consent and shall subsequently be assigned a 'Subject Number'. The closure will be percutaneous. An optional adjunctive endovascular balloon may be used to control bleeding. All safety data from the study will be assessed by the Data Safety Monitoring Committee on a continuous basis.

The Purpose of the Study is to assess safety and performance of the PerQseal® + Closure Device when used with the L PerQseal® 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.

Eligibility

 Yes No Not Sure

Inclusion Criteria

Over 18 years of age
Subject is willing and able to provide appropriate study-specific informed consent, follow protocol procedures, and comply with follow-up visit requirements
Clinically indicated for an endovascular procedure using a common femoral arteriotomy created by a 14 - 22 F sheath

Exclusion Criteria

Severe acute non-cardiac systemic disease or terminal illness with a life expectancy of less than four months
Evidence of systemic bacterial or cutaneous infection, including groin infection
Known bleeding diathesis (including sever liver disease), definite or potential coagulopathy, platelet count < 100,000/µl or patients on long term anticoagulants with an INR greater than 2 at time of procedure or known type II heparin-induced thrombocytopenia
Previous groin surgery within the region of the ipsilateral access
Severe; claudication or peripheral vascular disease (e.g. Rutherford category 3 or greater or ABI < 0.5), documented untreated iliac artery diameter stenosis > 50% or previous bypass surgery/stent placement in the common femoral artery of ipsilateral limb
Known allergy to any of the materials used in the PerQseal® + or PerQseal® Introducer (refer to Investigator's Brochure for materials list)
Subject has undergone a percutaneous procedure using a non-absorbable vascular closure device (excluding suture mediated) for haemostasis in the ipsilateral target leg
Patients that have undergone a percutaneous procedure in the ipsilateral leg, within the previous 30 days
Patients that have undergone a percutaneous procedure using an absorbable intravascular closure device for haemostasis, in the ipsilateral leg, within the previous 90 days
Evidence of arterial diameter stenosis > 20% or anterior or circumferential calcification within 20 mm proximal or distal to target arteriotomy site based on pre-procedure CT angiography
Females who are pregnant or lactating or in fertile period not taking adequate contraceptives. A pregnancy test may be performed
Patients that have a lower extremity amputation from the ipsilateral or contralateral limb
Target puncture site is located in a vascular graft
Procedural Exclusion Criteria
Arterial access other than common femoral artery obtained for ipsilateral target leg
Subject has a tissue tract expected to be greater than 10 cm
Significant blood loss/transfusion (defined as requiring transfusion of 4 or more units of blood products) during index procedure or within 30 days prior to index procedure
Unstable blood pressure or heart rate, symptoms of shock or systolic blood pressure greater than 160 mmHg (maybe controlled by pacing or pharmacologically eg. vasodilator such as nitrates etc.)
Activated clotting time (ACT) > 350 seconds immediately prior to sheath removal or if ACT measurements are expected to be > 350 seconds for more than 24 hours after index procedure
Target arteriotomy is in the profunda femoris or superficial femoral artery or is in common femoral artery, but within 15 mm proximal of the bifurcation of the Superficial Femoral /Profunda Femoris artery
PerQseal® Introducer-sheath to ipsilateral femoral artery diameter ratio is greater than or equal to 1.05. (vessel lumen diameter of less than 7 mm.)
Subjects with an acute haematoma of any size, arteriovenous fistula or pseudoaneurysm at the target access site; or any evidence of arterial laceration or dissection within the external iliac or femoral artery before the use of the PerQseal® + Closure Device
Use of thrombolytic agents within 24 hours prior to or during the endovascular procedure which causes fibrinogen < 100 mg/dl
