Introducing The UnBalloon Non-Occlusive Modeling Catheter. Unlike a balloon catheter, The UnBalloon catheter allows the modeling of aortic stent grafts without occluding blood flow. The nitinol mesh expands, allowing modeling of the stent graft snugly to the vessel wall. Blood flows freely - giving ample time to model the stent graft or repair an endoleak while minimizing the risk of stent graft migration during modeling.** The NEW UnBalloon Non-Occlusive Modeling Catheter Features: Non-Occlusive nitinol mesh design eliminates blood pressure spikes, which minimizes risk of stent graft migration during modeling** Radiopaque flexitip for effective trackability Nitinol mesh design offers the radial force of a balloon without the occlusion. Nitinol mesh and radiopaque bands are visible under fluoroscopy without contrast.** Compatible with .035” and .038” guidewires for effective trackability. Non-Occlusive design allows the physician to optimize radial force for stent graft modeling due to its tactile feedback.
