Benefits of technology

The present invention relates to an anchor used to treat paravalvular leakage. The anchor includes at least one tensioning member that causes both ends of the elongate anchor member to move towards each other. This movement creates a shorter distal or proximal portion of the anchor, thereby securing the paravalvular leakage between these parts. The technical effect of this invention is increased effectiveness and accuracy in the treatment of paravalvular leakage.

Problems solved by technology

This opening or space 1604 results in undesired leaking during pumping of the heart and is termed a valvular or paravalvular leak.

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...
