Kit for preventing distal embolism during endovascular interventions and method for preventing distal embolism during endovascular interventions using said kit

Abstract

Devices and methods are disclosed for preventing distal embolisms during endovascular interventions. Representative devices are kits that include a first catheter comprising a proximal part and distal part having a principal through lumen, at least one lumen for filling at least one balloon, at least one inflated balloon that closes the lumen of the right or left carotid artery, and a proximal end configured to allow blood to flow through the principal lumen but to block the passage of emboli. The kits include a second catheter in the form of a single-lumen tube with a proximal end and a distal end. The proximal and distal parts of the first catheter may have diameters that are sufficient to allow passage through the lumen of the second catheter and may be sufficiently long when combined to allow at least the distal part of the first catheter to extend beyond the limits of the distal end of the second catheter, when the first catheter passes through the second catheter. Moreover, the internal diameter of the lumen of the second catheter may exceed the external diameter of the distal part of the first catheter.
