Abstract
In at least one embodiment of the present invention a balloon catheter is provided. The balloon catheter comprises a shaft having a lumen formed therethrough. Connected to the shaft is an inflatable balloon. The inflatable balloon has a balloon wall defining a balloon interior surface and a balloon exterior surface that is opposite the interior surface. In fluid communication with the balloon wall is the lumen for inflating the balloon to define an inflated state and for collapsing the balloon to define a deflated state. The balloon wall is textured in the deflated state such that the balloon interior surface is spatially registered with the balloon exterior surface. The balloon in the inflated state is tensioned to have a surface roughness substantially less than a surface roughness of the balloon in the deflated state.
