Abstract

A device for treatment of mitral annulus dilation is disclosed, wherein the device comprises two states. In a first of these states the device is insertable into the coronary sinus and has a shape of the coronary sinus. When positioned in the coronary sinus, the device is transferable to the second state assuming a reduced radius of curvature, whereby the radius of curvature of the coronary sinus and the radius of curvature as well as the circumference of the mitral annulus is reduced.

Claims11

Dependent claims

A method of treating dilatation of a mitral valve annulus, comprising:

advancing a catheter into a coronary sinus, the catheter carrying an expandable implant that is in a radially collapsed configuration during the advancing, the implant comprising a distal portion, a proximal portion, and a central portion, the implant having a length extending from a proximal end to a distal end of the implant;
positioning the implant in a desired location in the coronary sinus;
expanding the distal and proximal implant sections of the implant in the coronary sinus;
permitting the distal and proximal implant sections to become endothelialized in the coronary sinus;
and
after permitting the distal and proximal implant sections to become endothelialized, decreasing the length of the implant by radially expanding the central section of the implant, thereby altering a shape of the coronary sinus by decreasing the length of the implant, thereby reducing a circumference of the mitral valve annulus.
