Abstract
A balloon dilatation catheter defines an inflation lumen communicating with its balloon, and a guidewire lumen extending along the catheter. An aperture portion is defined in the catheter shaft between the guidewire lumen and the catheter exterior, the aperture portion being covered by a frangible wall that is typically thinner than the rest of the tubular catheter shaft wall. The catheter may be used in either the conventional over-the-wire technique or the "rapid exchange" technique of balloon angioplasty.
