Implant for treatment of a heart valve, in particular a mitral valve, material including such an implant, and material for insertion thereof
First Claim
1. A method of percutaneously treating a portion of a heart valve positioned between an atrium and a ventricle;
- wherein the portion is selected from the group consisting of an annulus, a cardiac wall adjoining the annulus and both the annulus and the cardiac wall, the method comprising the steps of;
providing an implant comprising a helically wound wire defining a perimeter and an axis, the implant being arranged and configured such that the implant can be screwed into the portion of the heart valve so that at least part of the portion of the heart valve is located in the perimeter of the implant; and
the helically wound wire further defining a first coil having a first dimension and a second coil having a second dimension;
loading the implant within a catheter having a distal opening;
positioning the distal opening proximate the portion of the heart valve; and
moving the implant distally in relation to the catheter while driving the implant in rotation about the axis in order to insert the implant into the portion of the heart valve from the ventricle through the annulus and at least partially into the atrium;
wherein, when inserted, the second dimension is smaller than the first dimension;
wherein once the implant is inserted, the implant is oriented generally perpendicular to a plane that lies across an upper surface of the annulus and the implant contracts the portion of the heart valve located in the perimeter of the implant.

Abstract
Implants formed by a helically wound wire and methods of using same for the treatment of a mitral heart valve. According to the invention, it has dimensions such that it is able to be screwed into the wall of the annulus and/or into the cardiac wall adjoining the annulus such that a portion of the annulus and/or of the wall is located in the perimeter of the implant; and it comprises at least one first coil able, during said screwing of the implant, to insert itself into the wall while having a first dimension and at least one second coil having a second dimension, or adopting this second dimension after implantation, the second dimension being smaller than the first dimension such that the implant, once inserted, enables contraction of the wall portion located in the perimeter of the implant.
