Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The Cardiva VASCADE VCS consists of a sterile disposable catheter containing a deployable extravascular collagen patch and a clip. The VASCADE VCS is intended to seal a femoral arterial access site at the end of any procedure that uses a 6 or 7 French introducer sheath to access the femoral artery. This is a one time use device. The procedure of deploying the collagen patch takes less than 3-5 minutes.
Intervention code [1] 283841 0
Treatment: Devices
Comparator / control treatment
VASCADE VCS / Manual Compression
Randomization will be 2:1 treatment device to control ratio

Manual compression is the current standard treatment for post-procedure vascular management and involves compression applied by hand to the vascular access site until hemostasis is achieved, according to the Institution's guidelines.
Control group
Active

Outcomes
Primary outcome [1] 286083 0
The primary effectiveness endpoint is the time to achieve arterial hemostasis following device removal for Cardiva VASCADE VCS and sheath removal for manual compression
Timepoint [1] 286083 0
Index procedure
Primary outcome [2] 286084 0
The primary safety endpoint is the 30-day rate of combined access site-related major complications. Major complications include:
- Access site-related bleeding requiring transfusion - assessment of site-related bleeding is via direct observation and excessive blood loss would be determined via Institutional guidelines
- Vascular injury requiring repair - prolonged bleeding would require further assessment for vascular injury using techniques such as ultrasound imaging
- New ipsilateral lower extremity ischemia causing a threat to the viability of the limb and requiring surgical or additional percutaneous intervention - compromised blood flow is documented by subject symptoms, physical exam and/or a decreased or absent blood flow on lower extremity angiogram
- Access site-related infection - assessment made based on subject symptoms and physical exam
- New onset access site-related neuropathy in the ipsilateral lower extremity requiring surgical repair - assessment made based on subject symptoms and physical exam
- Permanent access site-related nerve injury (greater than 30 days) - based on subject symptoms and physical exam
Timepoint [2] 286084 0
Index procedure and 30 day Follow-up post procedure
Secondary outcome [1] 295092 0
The secondary effectiveness endpoint is time to ambulation.
Timepoint [1] 295092 0
Elapsed time between device removal for Cardiva VASCADE VCS and sheath removal for manual compression, and when subject stands and walks 20 feet without evidence of arterial re-bleeding from the access site
Secondary outcome [2] 295094 0
Time to discharge eligibility
Timepoint [2] 295094 0
Elapsed time between device removal for Cardiva VASCADE VCS and sheath removal for manual compression, and when subject is medically able to be discharged based solely on access site assessment.
Secondary outcome [3] 295095 0
Time to hospital discharge
Timepoint [3] 295095 0
Elapsed time between device removal for Cardiva VASCADE VCS and sheath removal for manual compression, and when subject actually is discharged from the hospital, as recorded on the discharge order.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
After each subject has been determined to meet all enrollment criteria, their eligibility criteria will be entered into an electronic database. The subject's randomization assignment then will be determined via central randomization by computer.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The randomization assignment will be determined by the database system based on the randomization scheme submitted by our biostatistician.
Masking / blinding

Summary
Brief summary
The Cardiva VASCADE VCS consists of a sterile disposable catheter containing a deployable extravascular collagen path and a clip.

The objective of the trial is to demonstrate the safety and effectiveness of the Cardiva VASCADE Vascular Closure System (VCS) in sealing femoral access sites and providing reduced times to hemostasis, time to ambulation, and time to discharge eligibility compared with manual compression at the completion of diagnostic or interventional endovascular procedures performed through 6 Fr or 7 Fr introducer sheaths.
