Study type
Interventional
Description of intervention(s) / exposure
In the Catheterization lab, provided no bleeding around the introducer sheath is observed and appropriate sterile technique is used, the Boomerang Catalyst VI Wire will be inserted through the indwelling 6F or 7F introducer sheath at the puncture site according to the Instructions for Use. After temporary hemostasis is achieved, imaging of the vessel will be performed to confirm correct placement of the device disc immediately prior to deployment of the extravascular collagen patch; the puncture site will then be observed for oozing blood and or signs of hematoma formation. At some point after hemostasis and prior to discharge, another ultrasound of the vessel will be performed and a digital image recorded as a baseline for the appearance of the collagen patch in proximity to the arteriotomy site.
Intervention code [1] 4435 0
Treatment: Devices
Comparator / control treatment
time to haemostasis using manual compression. no control group. Compared with average times for manual compression. As this is a safety and feasibilty study, no comparision will be made with other closure device times for haemostasis. A further Randomised Controlled Trial (RCT) will then be undertaken.
Control group
Uncontrolled

Outcomes
Primary outcome [1] 5826 0
The primary safety endpoint is the incidence of major adverse events of the image-guided investigational device did not exceed those of manual compression alone as reported in literature.
Timepoint [1] 5826 0
discharge and 30 days post procedure
Primary outcome [2] 5827 0
The primary effectiveness endpoint is to demonstrate a superior (reduced) hold time till haemostasis with the Boomerang Catalyst VI System image-guided, extravascular patch as compared to literature controls for manual compression alone.

Summary
Brief summary
The Boomerang Catalyst VI System is designed to help in controlling bleeding (gaining haemostasis) following an arterial puncture made for the purpose of completing a coronary angiogram or angioplasty (procedures done in the cardiac catheter laboratory to look for or treat narrowings in the coronary arteries). This puncture is usually made in the femoral artery in the groin. Often haemostasis is gained by manual compression (using the fingers or hand) and the literature reported average time for this technique will be compared the time it takes to gain haemostasis using the wire and collagen patch components of the device, as well as compression. There are several other closure devices used in New Zealand, and more than 50% of procedures would now have these used.

The device is placed into the femoral artery in the catheter laboratory once the angiogram has been completed, followed by a minimum of one minute of manual compression.

100 consecutive patients at 5 sites (20 per site) will be enrolled. The time taken to control the bleeding, time till the participant can stand and walk around, and the time till they are fit for discharge will be recorded. Also adverse, serious adverse and device adverse events will be recorded. Participants will be seen prior to discharge and again at 30 days and at these time points ultrasound will be used to assess the position of the collagen patch to the puncture site.
