The Cardiva Medical Boomerang™ Wire is intended to promote hemostasis at arteriotomy sites as an adjunct to manual compression. The Boomerang™ Wire is indicated for use in patients undergoing diagnostic femoral artery catheterization procedures, using 5 or 6 Fr introducer sheaths.
The Boomerang™ Wire consists of a sterile disposable Boomerang Wire and a sterile disposable Boomerang Clip (refer to the detailed Figures 1,2,3 in Section VIII). In conjunction with manual compression, the Boomerang Wire provides hemostasis at a femoral access site after femoral arterial catheterization while allowing continued distal perfusion. After completion of catheterization, the Boomerang Wire is inserted into the artery through the existing introducer sheath. After insertion, the distal tip of the Boomerang Wire is deployed, which opens the ffat, low-profile Boomerang Disc within the lumen of the femoral artery. The Boomerang Disc is then pulled back gently to the distal end of the introducer sheath. The introducer sheath is then removed from the vessel over the Boomerang Wire and the low-profile Boomerang Disc is positioned against the inside of the arteriotomy. Gentle upward tension is applied to the Boomerang Wire, which conforms the Boomerang Disc to the contours of the vessel and secures it against the intima, sealing the arteriotomy. The tension is then held in place by the external Boomerang Clip at the surface of the skin at the puncture site. The tension between the Boomerang Disc and the Boomerang Clip creates a site-specific compression of the arteriotomy and tract and establishes temporary hemostasis. This allows natural recoil of the smooth muscle of the vessel wall to occur at the arteriotomy site while the body's natural clotting process begins. Following the procedure, the Boomerang Disc is collapsed and the Boomerang Wire is completely removed from the artery. No part of the device is left behind nor is there any material introduced to alter the body's own natural clotting process. Final closure of the vessel occurs with manual compression to close the remaining needle puncture site left by removing the Boomerang Wire.
I am sorry, but the provided text does not contain the detailed information necessary to answer your request. The document describes the Boomerang™ Wire device, its intended use, predicate devices, and the fact that performance testing (bench, biocompatibility, animal, and post-market clinical data) was performed to demonstrate substantial equivalence. However, it does not specify the acceptance criteria for these tests, the reported device performance against those criteria, or details regarding sample sizes, data provenance, expert involvement, adjudication methods, or specific study designs (like MRMC or standalone studies).
Therefore, I cannot create the table or provide specific answers to questions 1 through 9.
