Abstract
A method for remodeling a body lumen, such as a coronary artery, having a stenosis to expand the stenosis comprising the steps of increasing the temperature of the body lumen and stenosis at the region of the stenosis for a time period and to a temperature level sufficient to cause a change in the stenosis and body lumen region from a relatively solid state into a softer and more moldable state and thereafter expanding the stenosis and the body lumen region while in the softer and more moldable state to thus reduce the tendency to fracture during expansion, and reducing the temperature of the stenosis and body lumen region while maintaining the expansion for a time period and to a temperature level sufficient to re-establish the relatively solid state thereof so as to increase the tendency to maintain the stenosis and body lumen region in the expanded condition. An improved heat applying balloon catheter is provided including passages for displacing the heated balloon inflating liquid with a cooling liquid to carry out the method.

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.
