Abstract

The present teachings provide devices and methods for treating tricuspid regurgitation. Specifically, one aspect of the present teachings provides an apparatus and method for identifying a suitable location on the tricuspid annulus with a positioning line at the identified suitable location Translating the positioning line across the tricuspid annulus Traversing and placing one tissue anchor, placing two or more tissue anchors, and coupling the tissue anchor to the flexible tension member and applying tension to the flexible tension member coupled to the two or more tissue anchors Tissue is folded between each pair of two or more tissue anchors on the tensioning member and the circumference of the tricuspid annulus is reduced. As a result, back jetting is reduced or eliminated.

Description

technical field [0001] The present teachings generally relate to novel tissue anchors and their use in percutaneous flap repair. Background technique [0002] Tricuspid valve disease involves symptoms of an improperly functioning valve between the two right heart chambers (ie, the right ventricle and right atrium), and these diseases often occur with other heart valve problems. Examples of tricuspid valve disorders include tricuspid regurgitation, tricuspid stenosis, tricuspid atresia, and Eberstein's anomaly. In tricuspid regurgitation, the tricuspid valve does not close properly and blood flows back into the right atrium; in tricuspid stenosis, the tricuspid valve narrows and reduces the amount of blood flowing into the right ventricle; in tricuspid atresia, congenital In heart disease, a solid wall of tissue prevents blood from flowing between the two right heart chambers; in Eberstein's anomaly, the malformed tricuspid valve sits lower than its normal position within th...
