Abstract
A method of manufacturing a porous elastic membrane that may be used in a balloon assembly of a balloon catheter is described. In the method, an elastic membrane material is expanded beyond an intended deployment expansion to a hyper-expanded state. Apertures are then formed in the hyper-expanded material. After contraction, the now-porous membrane can be used to form the outer wall of the balloon assembly. An aperture formed in the hyper-expanded membrane will have a smaller diameter than when the balloon is inflated to a smaller deployment expansion in the patient's body.
