OUTBACK Elite Re-Entry Catheter
OUTBACK Elite Re-Entry Catheter
The OUTBACK Elite Re-Entry Catheter is Cordis’s purpose-built device for true lumen re-entry following subintimal dissection in peripheral arterial intervention — a technique increasingly employed in complex femoropopliteal and iliac CTO recanalization when antegrade intraluminal wire crossing fails.
Mechanism of Action
The OUTBACK Elite resolves one of subintimal angioplasty’s most technically challenging moments — the re-entry step — by delivering a deployable nitinol needle at a precise 90-degree angle from the catheter’s distal tip, guided by real-time fluoroscopic orientation using the device’s L-shaped radiopaque marker system.
The operator aligns the L-marker under fluoroscopy to confirm lateral needle direction toward the true lumen, then deploys the needle to puncture back through the subintimal dissection plane, re-establishing guidewire access to the distal true lumen for balloon delivery and stenting. The system accepts standard 0.014” guidewires and is compatible with 6Fr or larger guiding sheaths.
