First Claim
1. A medical device designed to be used with a guide catheter, said medical device including a body having a cross-sectional area that is less than a cross-sectional area of an inner passageway of the guide catheter, said body including an internal passageway having a cross-sectional area that is adapted to be large enough to enable a treatment device to at least partially move within said internal passageway, said body having a longitudinal length that is at least about 10% of a longitudinal length of the guide catheter, said body at least partially formed of a flexible material.

Abstract
A medical device designed to be used with a guide catheter. The medical device has a body and cross-sectional shape and size that enables the guide catheter to be at least partially fed through a guide catheter. The body of the medical device has a longitudinal length that is at least about 10% of a longitudinal length of the guide catheter. The body of the medical device is at least partially formed of a flexible material.

34. A method of treating a diseased area of a body passageway comprising:
-
a. inserting a guide catheter at least partially through a body passageway until one end of said guide catheter is within about 18 inches or less from the diseased area, said guide catheter having an inner passageway; and
,b. inserting a medical device into at least a majority longitudinal length of said inner passageway of said guide catheter, said medical device including a body having a cross-sectional area that is at least 5% less than a cross-sectional area of said inner passageway of the guide catheter, said body including an internal passageway having a cross-sectional area that is adapted to be large enough to enable a treatment device to at least partially move within said internal passageway, said body having a longitudinal length that is at least about 10 cm. - View Dependent Claims (35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47)
