By a News Reporter-Staff News Editor at Politics & Government Week -- From Washington, D.C., VerticalNews journalists report that a patent application by the inventor Nardeo, Mahase (Oaks, PA), filed on , was made available online on .

The patent's assignee is VascuTech Medical LLC.

News editors obtained the following quote from the background information supplied by the inventors: "Dialysis catheters are generally inserted into the blood vessels using two different techniques: percutaneously (i.e., over a guide wire), and using a tearaway sheath. Catheters with a hard durometer can be easily inserted percutaneously because they have excellent column strength and do not kink easily during the insertion procedure. However, catheter with soft durometers cannot be easily inserted unless a stylet is fitted into the lumens to strengthen the create column.

"Additionally, it is even more difficult to insert a catheter with a split tip because both lumens are separated and need to be properly attached together in order to be inserted easily. In this regard, the invention described herein addresses these problems."

As a supplement to the background information on this patent application, VerticalNews correspondents also obtained the inventor's summary information for this patent application: "The following discloses a simplified summary of the specification in order to provide a basic understanding of some aspects of the specification. This summary is not an extensive overview of the specification. It is intended to neither identify key or critical elements of the specification nor delineate the scope of the specification. Its sole purpose is to disclose some concepts of the specification in a simplified form as to prelude to the more detailed description that is disclosed later.



"Some embodiments of the present invention comprise a venous lumen that is in a side-by-side configuration with an arterial lumen, wherein the two lumens are held together via a catheter hub. Each of the lumens comprises a stylet therein, further wherein the stylets extend beyond the proximal and distal ends of each of the lumens. The stylet for the venous lumen comprises an aperture near the distal end thereof so as to receive the distal end of the stylet for the arterial lumen therethrough, thereby connecting the venous and arterial lumens together. In this way, the stylets are configured to create column strength for dual-tip catheters such as split tip and step tip catheters.

"It is, therefore, an objective of the present invention to provide a new and improved catheter insertion assembly for use with catheters with separated distal ends or dual-tips (e.g., split tip and step tip catheters).

"It is another objective of the present invention to provide a new and improved catheter insertion assembly that increases the ease of inserting dialysis catheter with soft durometers.

"It is still another objective of the present invention to provide a new and improved catheter insertion assembly that can temporarily attach the distal ends of split tip or step tip catheter together in order for the catheter to be inserted easily into the body.

"It is still yet another objective of the present invention to provide a new and improved catheter insertion assembly that can properly attach the distal ends of split tip or step tip catheter together without requiring an additional fastening mechanism.

"A final objective of the present invention to provide a new and improved catheter insertion assembly that can be retroactively installed in existing split tip or step tip catheters.

"In the light of the foregoing, these and other objectives are accomplished in accordance with the principles of the present invention, wherein the novelty of the present invention will become apparent from the following detailed description and appended claims."
