CATHETER WITH STEPPED SKIVED HYPOTUBE

摘要

Catheter having a hypotube with a skive defined by a first angled cut, an axial cut, and a second angled cut. A midshaft member includes a guidewire lumen and an inflation lumen in fluid communication with an inflation lumen of the hypotube, the inflation lumen of the midshaft member configured to receive at least a portion of the hypotube. A distal tabular shaft member extends distally from the midshaft member. The distal tubular shaft member has a guidewire lumen and an inflation lumen defined therein, the guidewire lumen of the distal tubular shaft member in fluid communication with the guidewire lumen of the midshaft member. The inflation lumen of the distal tubular shaft member is in fluid communication with the inflation lumen of the midshaft member and a balloon is coupled to the distal tubular shaft member and in fluid communication with the inflation lumen.
