VALLECILLA ERAZO, Carolina et al. Development and evaluation of a balloon-coil device for occlusion by catheterization techniques of the arteriosus ductus. rev.ing. [online]. 2005, n.21, pp.40-45. ISSN 0121-4993.

The Patent Ductus Arteriosus (DAP) is a vascular congenital defect. The goal of this project was to develop a universal, low cost balloon-coil device (BCD) to close DAP and to evaluate its safety and efficiency in an animal model. The design and fabrication of the BCD were improved developing a device that fits different DAP diameters. It can be managed with conventional catheterism techniques. All the procedures related with BCD ended in a utility patent application. The experimental model was implemented in newborn calves. 14 experiments were performed. Optimal guidelines for pre, in and post surgery procedures were established. Successful implantation and proper liberation of the device was achieved in three experiments. A complete successful implantation of BCD and a complete occlusion was accomplished in one experiment. More successful experiments have to be done.

Keywords : Ductus Arterioso Persistente (DAP); Dispositivo Balón Coil (DBC).
