Details and patient eligibility

About

The objective of this Early Feasibility Study (EFS) is to evaluate the initial safety and preliminary effectiveness of the PerQseal®+ VCD in a small number of subjects when used to achieve hemostasis of common femoral arteriotomies created by 14 to 22 F sheaths (arteriotomy up to 26 F) in subjects undergoing Percutaneous Transcatheter procedures.

Full description

This study is a prospective, multi-center, single arm EFS. Patients undergoing a percutaneous trancatheter procedure, requiring an arteriotomy created by 14 - 22 F sheaths (arteriotomies up to approx. 26 F), via the common femoral artery will be screened against the study inclusion/exclusion criteria. If the patient meets study eligibility requirements, they shall be invited to participate, provide informed consent, and shall subsequently be assigned a study ID number. Enrollment will occur at the point where the PerQseal®+ VCD study device first enters the patient's body.

The planned enrollment is 15 treated patients at a maximum of 5 study sites (minimum of 3) located in the United States.

Enrollment: 15 patients

Sex: All

Ages: 19+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

1. Age ≥ 19 years, 2. Clinically indicated for a large bore interventional transcatheter procedure, e.g., transcatheter aortic valve repair (TAVR) or endovascular abdominal aortic aneurysm repair (EVAR), or thoracic endovascular aneurysm repair (TEVAR) using a percutaneous common femoral arteriotomy created by a 14 to 22 F sheath, 3. Subject is willing and able to provide appropriate study-specific informed consent, follow protocol procedures, and comply with follow-up visit requirements, 4. Females who are not pregnant or lactating and not planning to become pregnant for the duration of the study.

10. Renal insufficiency (Glomerular Filtration Rate ≤ 30 ml/min or baseline serum creatinine > 2.5 mg/dL) or on renal replacement therapy,
11. Known allergy to any of the materials used in the PerQseal®+ device (refer to Instructions for Use),
12. Subject unsuitable for surgical repair of the target leg access site,
13. Subject has undergone a percutaneous procedure greater than 8 F sheath in the target leg, within the 90 days prior to index procedure,
14. Subject has undergone use of an intra-aortic balloon pump through the target leg access site within 90 days prior to the index procedure,
15. Subject has undergone a percutaneous procedure of 8 F sheath or less using an absorbable intravascular closure device for hemostasis, in the target vessel, within the 90 days prior to index procedure,
16. Subject has undergone a percutaneous procedure of 8 F sheath or less using a suture mediated closure device or manual/mechanical pressure for hemostasis in the target leg, within the 30 days prior to index procedure,
17. Evidence of marked tortuosity of the femoral or external iliac artery in the target leg, based on pre-primary procedure CT angiography,
18. Evidence of arterial diameter stenosis > 30% within 15 mm proximal or distal to arteriotomy site based on pre-primary procedure CT angiography,
19. Evidence of anterior wall calcification of the target common femoral artery (other than small, diffuse deposits which in the opinion of the investigator will not impede the vascular closure procedure) within 15 mm proximal or distal to arteriotomy site based on pre-primary procedure CT angiography,
20. Target femoral artery diameter is less than 7 mm in diameter, based on pre-primary procedure CT angiography,
21. Further planned endovascular procedure in the target leg in the 30 days following the index procedure,
22. Subject is enrolled in another investigational medical device or drug study
23. Subject has been previously enrolled in this clinical study.
24. Current COVID-19 infection (with or without symptoms), recent positive test for COVID-19, or recent exposure (within two weeks) to a person with COVID-19 infection.

Procedural Exclusion Criteria If any Procedural Exclusion Criteria listed below, then closure with PerQseal®+ device is not permitted.

1. Initial common femoral arterial access achieved with manual palpation or blind arterial stick access, without use of an image guided approach (ultrasound or angiography).

2. Difficult dilation during initial target femoral artery access (e.g., that damages or kinks sheath dilators) while step-dilating up to the large-bore device,

3. During arterial puncture, the target femoral artery suspected to have experienced a back arterial wall needle puncture or underwent > one needle puncture during the primary procedure.

4. Subject has a tissue tract (i.e., estimated distance from skin entry point to arterial anterior surface at arteriotomy) expected to be greater than 8 cm,

5. Significant blood loss requiring transfusion of blood products during primary procedure or within 30 days prior to index procedure,

6. Activated clotting time (ACT) > 300 seconds immediately prior to sheath removal or if ACT measurements are expected to be > 300 seconds for more than 24 hours after index procedure,

7. Target puncture site is in a vascular graft,

8. Target arteriotomy greater than 26 F,

9. Target arteriotomy 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,

10. Target arteriotomy located at the level or above the inferior epigastric artery and/or beneath or above the inguinal ligament based on bony landmarks (above femoral head on A-P projection),

11. Subjects with an acute hematoma > 4 cm diameter, arteriovenous fistula, pseudoaneurysm, or intraluminal thrombosis at the target access site identified intra-procedurally,

12. Evidence of bleeding around the primary procedure sheath (BARC type 2 or higher),

13. Intra-procedural angiographic evidence of arterial laceration, dissection or stenosis within the femoral artery that would preclude use of the PerQseal®+ device,

14. Uncontrolled hypertension (systolic blood pressure > 180 mmHg or diastolic blood pressure > 110 mmHg) at the time of planned vascular closure,

15. Systolic blood pressure < 90 mmHg at the time of planned vascular closure.
