Abstract

Disclosed is a focal balloon having at least one reference zone and a focal zone. In one embodiment, the reference zone and focal zone are inflatable to a first generally cylindrical profile at a first pressure. At a second, greater pressure, the focal section expands to a second, greater diameter, while the reference zone remains substantially at the first diameter. In an alternate embodiment, the focal zone and the reference zone are inflatable to their respective predetermined diameters at the inflation pressure, in the absence of constricting lesions or anatomical structures. Multiple lobed and drug delivery embodiments are also disclosed.

Claims

1. A balloon catheter, comprising:

An elongate, flexible tubular body having proximal and distal ends;

a first inflatable balloon on the distal end of the tubular body;

a first inflation lumen extending through the tubular body and communicating with the first inflatable balloon;

a second inflatable balloon surrounding at least a portion of the first inflatable balloon;

a second inflation lumen extending through the tubular body and communicating with the second inflatable balloon;

wherein the second inflatable balloon is inflated to a first inflation profile by inflation of the first balloon, and the second balloon is inflatable to a second profile by inflation of the second balloon.
