Abstract: Embodiments of the present invention relate to constructive disposition introduced in an indeflator device applied in coronary angioplasty interventions for bi-arterial treatment and the kissing balloon technique. New introduced disposition in the indeflator and/or insuflator device is used in coronary angioplasty interventions especially to treat multiple bifurcation and bi-arterial lesions at the same time. Administering liquids or fluids at the indicated pressure used during surgical interventions, to inflate, control the pressure and also deflate balloon catheters, where this procedure is widely used in angioplasty interventions, enables the implementation of double endoprosthetic, also known as stent.
