Abstract
A catheter includes an elongated tube having a size and shape adapted to be inserted into the cardiovascular system that is composed of a material having a modulus of elasticity providing stiffness to enhance catheter torque control, and a sheath coaxially disposed over and bonded to the tube that is composed of a biocompatible material having a modulus of elasticity providing softness to reduce catheter trauma to the cardiovascular system. An outer portion of the tube defines a plurality of longitudinally-extending ribs protruding radially outward at circumferentially spaced-apart locations, each one of the ribs having a cross sectional area that increases radially inward, for engaging the sheath circumferentially, for defining an outer surface of the tube that generally faces radially outward toward the sheath to thereby facilitate a closely-confronting relationship between the sheath and tube over substantially the entire outer surface, and for extending the outer surface over an enlarged area to thereby facilitate a better bond of the sheath to the tube.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
