Abstract
A method and several assemblies for the reducing of mineralization of cardiovascular tissue in vivo is provided. The method involves contacting cardiovascular tissue, such as a valve or a vessel, with an acidic treatment solution. One apparatus is a balloon catheter assembly for the infusion of an acidic treatment solution into a define area of a cardiovascular tissue. A second apparatus is a flexible cup which forms a defined area with the wall of a vessel for the introduction of an acidic treatment solution for the reduction of mineralization of a vessel. A third apparatus is an assembly for the introduction of an acidic treatment solution on one side of a valve, and the removal of the acidic treatment solution from the opposite side of the valve. Each apparatus can take the form of an elongated catheter for use in minimally invasive procedures or as hand held devices for use in an open surgical field.

15. A method for infusing a demineralization solution into a cardiovascular tissue of a subject, comprising:
-
inserting a catheter into the cardiovascular tissue so that the catheter defines a blood flow passage, occluding a region within said cardiovascular tissue by inflating a first and a second balloon, wherein said first balloon defines the proximal end of said region and said second balloon defines the distal end of said region, infusing an acidic treatment solution having a pH of less than about 4 for a period of time sufficient to reduce mineralization. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22)
