Abstract
Apparatus and methods are provided for localized, minimally invasive administration of sclerotherapy in the treatment of varicose veins. A treatment site within a vein is isolated from blood flow through the vain. Sclerotherapeutic agents are delivered to the isolated vessel segment. A substantial portion of the agents are then removed from the vein, and isolation is removed from the treatment site. Inflammation, clotting, scarring, and closure of the varicose vein ensues at the treatment site. In a preferred embodiment, this technique is accomplished with a catheter having an inflatable member. The inflatable member is expandable to a deployed configuration in which its central region is of reduced cross-section as compared to its proximal and distal regions. The central region comprises one or more perforations extending through the inflatable member so that sclerotherapeutic agents may be delivered through the perforations.

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.
