1. A catheter comprising: a rod having a lumen and a distal part, an embolic filter mounted to slide along the distal part of the rod and having an opening for passage of the rod through it, and a porous cellular material forming a storage chamber for the captured emboli, the filter has a folded configuration and a deployed configuration in which the outer periphery of the filter comes into contact with the wall of a blood vessel to direct the flow of blood and potential emboli into the storage chamber, ipro a maximum stop to limit the proximal movement of the embolic filter along the distal part of the rod, or a distal stop to limit the distal movement of the embolic filter along the distal part of the rod, or both of these stops. 2. The catheter according to claim 1, further comprising an elastic seal located inside the opening of the catheter and intended to form a seal around the rod passing through the opening of the filter. 3. The catheter according to claim 1, wherein the porous cellular material comprises a cylindrical outer part and a conical inner part, the conical inner part being located inside the cylindrical outer part and having a wider proximal end connected to the cylindrical outer part and a narrow distal end connected to the hole for the passage of the rod, while the distal end of the embolic filter is open for blood flow between the specified conical inner part and the cylindrical outer part, and The relationship between the conical inside and the cylindrical outside limits1. Катетер, содержащий:стержень, имеющий просвет и дистальную часть,эмболический фильтр, установленный с возможностью скольжения по дистальной части стержня и имеющий отверстие для прохождения через него стержня, и пористый ячеистый материал, образующий накопительную камеру для захваченных эмболов, при этом фильтр имеет свернутую конфигурацию и развернутую конфигурацию, в которой наружная периферия фильтра входит в контакт со стенкой кровеносного сосуда для направления потока к
