摘要： Balloon catheters and methods for manufacturing catheter shafts are disclosed. In one example, a balloon catheter may include an outer tubular member disposed about an inner tubular member. In some cases, a fluid (e.g. cryogenic fluid) can be provided between the inner tubular member and the outer tubular member and may cool the inner tubular member. To help provide a relatively uniform temperature distribution around a circumference of the inner tubular member, two or more spacers, protrusions, or gap-maintaining members can be positioned between the outer tubular member and the inner tubular member to maintain a gap therebetween. In some cases, the spacers, protrusions, or gap-maintaining members may be attached to an inner surface of the outer tubular member or, in other cases, to an outer surface of the inner tubular member. In other embodiments, a step-down in an outer diameter of the outer tubular member is disclosed.

摘要： Methods and devices for biasing a balloon catheter are disclosed. In one example, a medical device may include a catheter shaft and a balloon assembly coupled to a distal region of the catheter shaft. The balloon assembly can define a chamber configured to be inflated and deflated using a fluid supplied from the catheter shaft. A biasing member may be positioned in the chamber of the balloon assembly and may be configured to bias the balloon assembly to a longitudinally extended state without obstructing an exhaust lumen of the catheter shaft. In some cases, the biasing member may be a spring. In other cases, the biasing member may be a coiled portion of a fluid supply line.
