1. A balloon catheter, comprising:
- a catheter shaft having a longitudinal axis with a proximal end and a distal end, said catheter shaft having an inflation lumen extending within at least a portion of a distal shaft section; and
a balloon comprising a material having a microstructure of interconnected fibrils, said balloon having a longitudinal axis, said material oriented helically with respect to the balloon'"'"'s longitudinal axis, wherein the balloon is mounted on the distal section of the catheter shaft with an interior chamber in fluid communication with the inflation lumen;
said balloon further comprising an elastomeric material.

Abstract
Balloon catheters having the strength and maximum inflated diameter characteristics of an angioplasty balloon and having the recovery characteristics during deflation of an elastic embolectomy balloon. The balloon catheter can be made in very small sizes and has a lubricious and chemically inert outer surface. The balloon catheter is easy to navigate through tortuous passageways, is capable of rapid inflation and deflation and has high burst strengths. Balloon covers having these same characteristics are also described for use with conventional embolectomy balloons or angioplasty balloons.
