Abstract
A horseshoe-shaped guide catheter for stent angioplasty of the ductus arteriosus in newborn and infants with ductal-dependent cardiopathies, characterized by a long, straight, hollow first section merged at the distal end thereof to a second section formed by a curved portion shaped as a circle section with radius (Ra) of 7.5 mm to 9 mm, arc (b) of 180° to 280° and distance (d) between the tip of the second section and the straight part of the first section without deformations of 7 mm and 15 mm. The angioplasty makes it possible to insert one or more stents that keep the ductus open in extrauterine life, improving survival of the newborn and young infants, allowing weight gain and undergo corrective surgery a few months later with safer and with better outcomes.
