The renal double curve catheter is an angiographic selective access catheter, designed for catheterization and subselection of acutely originating renal arteries 1 through a femoral approach, in order to secure access, advance, exchange devices, or deliver contrast.
It can also be used for the catheterization of the celiac trunk, superior mesenteric artery, or inferior mesenteric artery.

Instructions for vascular access
secure femoral vascular access with a sheath catheter
flush the renal double curve catheter and the navigation guidewire (Glidewire®)
insert the Glidewire in the RDC catheter and then place the assembly in the sheath catheter
advance the the Glidewire until reaching the the target ostium, bony landmarks can be used as reference
advance the catheter over the Glidewire until reaching the tip of the wire.
retract the wire to allow the tip of the catheter to form
advance and retract the catheter until the target ostium is catheterized
advance the Glidewire in the target vessel and then secure the catheter by advancing it on the wire
Precautions
To decrease the risk of vascular injury
catheters should always be inserted and withdrawn over wires, as the tip of catheters moving within a vessel can cause dissection
always verify the catheter pressure rate limit while using the power injector since surpassing these thresholds can damage both the catheter and the blood vessel
in case of resistance while advancing or withdrawing the catheter, it is important to stop and identify the underlying cause of the resistance before proceeding further
avoid bending or kinking the catheter before its placement, as doing so may damage the catheter and lead to injury for the patient
