Abstract
The invention is embodied in an appliance or a prosthesis and a delivery catheter for use in a vein for minimally invasive treatment of chronic venous insufficiency. The system and method of the invention eliminate the need for open surgical valve repair procedures, obviate the need for arm vein transplantation into the leg, and allow patients to return to their former active lifestyles without the limitations currently associated with the treatment of this condition. An incompetent valve to be repaired is identified by injected contrast through the delivery catheter or similar means and the catheter is positioned at that valve, a clip appliance or similar prosthesis is deployed from the catheter and affixed to the valve. Next, the delivery catheter is repositioned and appliances or prostheses are deployed on sequentially lower valves until all desired valves are repaired and functionally competent.

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.
