ABSTRACT:
Dilatation catheters for use in administering treatments to relieve stenotic regions within a body lumen while maintaining blood flow past the dilatation balloons are described. According to the present invention, perfusion ports are provided in both a guidewire lumen and in a bypass lumen in several alternative embodiments in order to provide increased blood flow past the dilatation balloon.
