Devices for treating paravalvular leakage and methods use thereof

Abstract

An aspect of the present teachings includes a method of percutaneously treating a paravalvular leakage. In a preferred embodiment, the method includes providing an anchor having an elongate anchor member and a tensioning member, positioning the anchor through a paravalvular leakage, deploying the anchor wherein at least a part of the distal portion of the elongate anchor member is on one side of the paravalvular leakage, and applying tension to the tensioning member so that at least a part of the distal portion of the elongate anchor member transitions from the elongate configuration to the shortened configuration. Another aspect of the present teachings includes a device that can be used in a method of percutaneously treating a paravalvular leakage.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application is based on and claims priority to U.S. Provisional Patent Application 62 / 128,997, filed Mar. 5, 2015, the entire contents of which is incorporated by reference herein as if expressly set forth in its respective entirety herein.BACKGROUND[0002]Paravalvular leakage is a complication associated with the implantation of a prosthetic valve. It may occur both in traditional surgical or minimally invasive transcatheter approaches. FIG. 1 illustrates an artificial valve 1600 that may include, for example, a multi-leaflet structure 1602 and that may be implemented in an appropriate manner as will be appreciated by those of ordinary skill in the art. Additionally, a small opening or space 1604 between the heart 1606 and the valve 1600 is shown as may occur in some instances of valve replacement. This opening or space 1604 results in undesired leaking during pumping of the heart and is termed a valvular or paravalvular leak.[0003]Ac...

AI Technical Summary

Benefits of technology

[0009]In various embodiments, the anchor includes at least one tensioning member. In some embodiments, the tensioning member causes both ends of the elongate anchor member to move towards each other. This motion can create a shortened distal portion and/or a shortened proximal portion. In certain embodiments, doing so secures the paravalvular leakage between the distal and the proximal portions of the elongate anchor member.

[0010]In embodiments where an anchor of the present teachings includes two elongate anchor members, the tensioning member causes at least one of the two elongate anchor members to move towards the other elongate anchor member. I
