The Balloon in Balloon (BIB®) Stent Placement catheters are an innovative technology pioneered by NuMED to insert stents in a two-stage implantation process. This enables stents to be opened or expanded evenly and positioned correctly within the vessel. The inner balloon of the BIB® catheter is half the diameter of the outer balloon and is 1.0 cm shorter in length. The BIB® stent placement balloon catheter is available in 12.0-30.0 mm diameters and 2.5-6.5 cm lengths.
