Catheter having a plurality of integral radiopaque bands
First Claim
1. A guide catheter comprising:
- an elongate, tubular, polymeric body including one or more structurally significant axial bends defined thereon and a plurality of other tubular sections;
at least one tubular first segment forming a portion of said tubular polymeric body having a first radiopacity, said at least one tubular first segment overlaying at least a portion of a corresponding one of the structurally significant bends, anda plurality of tubular second segments having a second radiopacity and overlaying at least a portion of the plurality of other tubular sections of the tubular polymeric body with none of the at least one first segments positioned to significantly overlap the other tubular sections,wherein said first and second segments abut one another and wherein said first radiopacity is different than said second radiopacity with said radiopacity difference provided primarily by a radiopaque material incorporated into said polymeric tubular body.

Abstract
A tubular member for manufacture of medical devices insertable into body lumens. The tubular member includes an inner tubular member, and outer tubular member, and a lumen through the inner tubular member. The outer tubular member has a plurality of radiopaque segments formed of radiopaque material incorporated into the tube polymeric material. One tubular member has highly radiopaque segments separated by less radiopaque segments at intervals greater than the radiopaque segment length, such that the radiopaque segments serve as marker bands. Another tubular member has long radiopaque segments separated by less radiopaque segments at intervals less than the radiopaque segment length, such that the less radiopaque segments serve as marker bands. Marker bands can be located at either regular intervals to aid in measuring internal dimensions or at significant structural locations to aid in catheter positioning.

9. A tubular assembly for a guide catheter comprising:
-
one or more structurally significant bends and one or more other tubular sections, one or more highly radiopaque segments abutting one or more less radiopaque segments, said one or more highly radiopaque segments having a higher radiopacity than said less radiopaque segments, wherein said highly radiopaque segments are formed of polymeric material, and have said higher radiopacity resulting primarily from loading said polymeric material with a radiopaque material, and each of the highly radiopaque segments positioned to overlay at least part of one of the structurally significant bends, with none of the highly radiopaque segments significantly overlaying the one or more other tubular sections. - View Dependent Claims (10, 11, 12, 13)

14. A tubular assembly for a guide catheter comprising:
-
one or more structurally significant bends and one or more other tubular sections, one or more highly radiopaque segments abutting one or more less radiopaque segments, said one or more highly radiopaque segments having a higher radiopacity than said less radiopaque segments, wherein said highly radiopaque segments are formed of polymeric material, and have said higher radiopacity resulting primarily from loading said polymeric material with a radiopaque material, and each of the less radiopaque segments positioned to overlay at least part of one of the structurally significant locations, with none of the less radiopaque segments significantly overlaying the one or more other tubular sections.
