Abstract
The improved balloon catheter includes a first tubular segment, which has multiple zones of differing malleability along its length. The catheter further includes a coaxially aligned hypotube formed of a malleable material, which is positioned within the lumen of the first tubular segment and extends from the distal end of the first tubular segment. In one embodiment the hypotube runs the length of the first tubular segment; while in another embodiment, the hypotube runs along only a portion of the length of the first tubular segment. A portion of the outer circumferential surface of the hypotube is permanently affixed and sealed to an inner circumferential surface of the first tubular segment in the vicinity of the distal end of the first tubular segment. The outer circumference of the distal end of the first tubular segment is gently tapered along its length so as to smoothly transition to the circumference of the hypotube. The hypotube terminates with an atraumatic tip and includes a balloon dilator affixed near the tip. An aperture near the tip of the hypotube fluidly connects the interior of the balloon with the lumen of the hypotube enabling the balloon to selectively expand and contract.

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.
