Catheter including a bare metal hypotube

摘要

Catheter and methods for designing, making, and using catheters are disclosed. An example catheter is a balloon catheter. The balloon catheter may include a proximal shaft. The proximal shaft may be a bare metal hypotube having a skew value of −1.0 to −2.5. A midshaft may be attached to the proximal shaft. A distal shaft may be attached to the midshaft. A balloon may be coupled to the distal shaft. An inflation lumen may be defined that extends from the proximal shaft, through the midshaft, and into the distal shaft. The inflation lumen may be in fluid communication with the balloon.

1. A balloon catheter, comprising:
a proximal shaft; wherein the proximal shaft is a bare metal hypotube free of a lubricious coating having a skew value of −1.0 to −2.5; a midshaft attached to the proximal shaft; a distal shaft attached to the midshaft; a balloon coupled to the distal shaft; and wherein an inflation lumen is defined that extends from the proximal shaft, through the midshaft, and into the distal shaft, the inflation lumen being in fluid communication with the balloon.
