FIELD: medicine.SUBSTANCE: group of inventions refers to medicine, namely to cardiovascular surgery. A catheter for coronary artery catheterisation comprising some integral parts: proximal (IV), distal (I-II) with a tip and intermediate (III) parts in between. In the catheter for left coronary artery catheterisation, a junction point of the proximal (IV) and intermediate (III) parts forms a proximal bend. The distal (I-II) part is bent so as to provide a position of the tip catheter at the coronary artery mouth. The distal (I-II) part bend and the proximal bend face one way and are found on one side from the intermediate (III) part. The distal (I-II) and intermediate (III) parts bend face oppositely. In the catheter for right coronary artery catheterisation, a junction point of the proximal (IV) and intermediate (III) parts forms a proximal bend. The distal (I-II) part is bent so as to position the catheter tip at the coronary artery mouth with the distal (I-II) part bend and the proximal bend face one way and are found on many sides from the intermediate (III) part. The distal (I-II) and intermediate (III) parts bend face oppositely. A method for coronary artery catheterisation is implemented by the declared catheters.EFFECT: group of inventions enables providing the coronary artery catheterisation from the venous approach where it is impossible to deliver the catheter through the artery by the original design of the catheters.11 cl, 17 dwg, 2 tbl |
