Abstract

A method of treating a target region in a body lumen, said method comprising: directing a uniform dose of ultrasonic energy from an interior of the lumen radially outward over a treatment length of the lumen, wherein the dosage of ultrasonic energy received at any one point along the length varies by no more than plus or minus 6 decibels from that received at any other point along the length.

Claims

1. A method of treating a target region in a body lumen, said method comprising:

directing a uniform dose of ultrasonic energy from an interior of the lumen radially outward over the length of the target region of the lumen, wherein the dosage of ultrasonic energy received at any one point along the length varies by no more than plus or minus 6 decibels from that received at any other point along the length.
