Abstract

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 tubular 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.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Provisional Patent Application Serial No. 61 / 490,547, filed May 26, 2011, entitled "Catheter With Stepped Skived Hypotube," which is hereby incorporated by reference in its entirety. technical field [0003] The subject matter disclosed herein relates generally to medical devices, and in particular to in vivo devices, such as balloon catheters, for therapeutic or diagnostic use. Background technique [0004] In percutaneous coronary angioplasty (PTCA), a guide catheter is advanced through the patient's vasculature until the distal end of the guide catheter is secured in the desired coronary artery. A guidewire is advanced from the distal end of the guide catheter into the coronary artery until the distal end of the guidewire passes through the dilated lesion. A dilation catheter with an expandable balloon at its distal portion is advanced over a previously introduced guidewire...
