Abstract
An improved catheter insertion assembly having a transparent tubular member open at each end; a plunger assembly slidable within the tubular member having a stem portion at a first end; and at least a partially transparent chamber having a needle base and sealing member on a second end of the plunger assembly; an elongated tubular needle embedded within the needle base and extending there from with the needle in fluid communication with the transparent chamber; a catheter assembly, a transparent cannula and a transparent hub attached to the second end with the tubular needle passing longitudinally through the cannula; a fluid passage formed between the needle and the cannula so that when the plunger is retracted a vacuum is established within the fluid passage and blood is visibly drawn through the fluid passage into the transparent cannula and if volume permits, blood then would be visible in the transparent hub, and then if volume permits blood would be visible in the void of the catheter body (barrel) created by pulling the plunger; and wherein the tubular needle is threaded through a lumen of the cannula; and wherein the sealing member provides a sliding seal between the plunger assembly and the transparent tubular member; and wherein, a fluid communication exists through the needle into the flashback chamber of the plunger apparatus and through a porous vent. The distal end of the catheter device described herein has the addition of an external flange and dual plunger paddles which allow dynamic positioning of the fingers and one handed operation. Furthermore these structures are ergonomically associated to maximize finger surface area operation; and wherein the user can change the orientation of the beveled needle.

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.
