Abstract
A multilumen catheter assembly and methods for making and inserting the same are provided. The catheter assembly includes a unitary catheter and at least two distal end tubes which extend distally from the unitary catheter. The at least two lumens in the unitary catheter are in fluid communication with passageways through the distal end tubes. The catheter assembly may be made by extruding a unitary catheter tube having internal longitudinally extending lumens, then splitting the tube on its distal end portion to form distal end tubes. The tubes are then ground and polished to form a smooth surface on the exterior of the tubes. The catheter assembly may also be made by forming an outer layer on at least two longitudinally extending catheters while leaving two distally extending portions of the tubes outside the outer layer to form the distal end tubes. The multilumen catheter assembly may be inserted in a patient for acute and chronic catheterization and subcutaneously tunneled and inserted using a single insertion procedure while leaving the distal end tubes within the vessel capable of free movement and sealing the insertion site into an area to be catheterized.

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.
