Boomerang ClosureWire Vascular Closure System (VCS)

• The Boomerang device provides immediate hemostasis and allows the arteriotomy to relax back around the Boomerang Wire while normal clotting mechanisms begin.
• The arteriotomy site closes via natural mechanismselastic recoil and thrombosis.
• The original arteriotomy (e.g., 8 Fr. OD for a 6 Fr. arterial sheath) is "down-sized" to diameter of Boomerang Wire (approximately a 20 gauge needle).
• The Boomerang device creates a site-specific compression of both the arteriotomy and tract, unlike manual compression where general pressure is diffused across a broad area.
• Temporary placement of low-profile, conformable disc against the intima provides immediate hemostasis and secure seal in the cath lab in under 30 seconds.
• Precise, targeted compression provides immediate hemostasis and allows the arteriotomy to close naturally and normal clotting mechanisms to begin.

The Boomerang ClosureWire technique creates a site-specific compression between the inside of the arteriotomy and just outside the tissue tract, resulting in a targeted internal compression of both the arteriotomy and tract. The device is deployed, which creates immediate hemostasis and a secure seal in the cath lab in under 30 seconds. With the device in place, the arteriotomy relaxes back naturally around the Boomerang Wire (0.037 inches) while normal clotting mechanisms begin. Natural elastic recoil of the arteriotomy is known as the Boomerang Effect, which returns the arteriotomy to its original puncture size (approximately a 20 gauge needle). Following the procedure, the device is completely removed, leaving nothing in the artery or tissue tract. Final hemostasis is achieved with just a few minutes of occlusive finger pressure to close the remaining needle puncture site left by removing the Boomerang ClosureWire device.
