ABSTRACT:
A dilatation catheter is described wherein a plurality of oblong perfusion ports are provided in the catheter shaft to provide perfusion flow of blood through the distal section of the catheter. Oblong perfusion ports are preferably provided both proximal and distal to the inflatable dilatation balloon. Orienting the long dimensions of the oblong perfusion ports at an angle from the longitudinal axis of the catheter shaft minimizes kinking of the catheter shaft when passing through tortuous passageways.
