Abstract
An intravascular catheter comprises a plastic tube of a diameter capable of occupying a blood vessel. The plastic tube defines a tapered distal tip. The distal tip comprises an annular, distal end portion having an outer diameter that tapers at a first acute angle to the tube longitudinal axis, distally and inwardly to a thin, annular, distal end surface. The tube also defines a second, tapered, annular portion proximal of and next to the annular, distal end portion. The second portion defines an outer diameter that tapers distally and inwardly down to an outer diameter of essentially no less than the maximum outer diameter of the annular, distal end portion. The second portion tapers at a second acute angle to the longitudinal axis, which is less than the first acute angle. Also, an improved composition for the cannula tube is disclosed.
