Devices and Methods for Percutaneous Tricuspid Valve Repair

摘要

The present teachings provide devices and methods of treating a tricuspid valve regurgitation. Specifically, one aspect of the present teachings provides devices and methods of identifying a suitable location on the tricuspid annulus, another aspect of the present teachings provides devices and methods of placing a wire across the tricuspid annulus at such an identified location, another aspect of the present teachings provides devices and methods of deploying a tissue anchor across such an identified location, and yet another aspect of the present teachings provides devices and methods of applying tension to two or more of such tissue anchors and reducing the circumference of the tricuspid annulus. As a result, a regurgitation jet is reduced or eliminated.

主权项

1. A method for anchoring tissue within a heart of a patient comprising the steps of:
locating a first tissue location inside a right ventricle; deploying a distal portion of a first tissue anchor at the first tissue location such that the distal portion is deployed into the right ventricle; deploying a proximal portion of the first tissue anchor at the first tissue location such that the proximal portion is deployed inside the right atrium; locating a second tissue location inside the right ventricle; deploying a distal portion of a second tissue anchor at the second tissue location such that the second anchor tissue is deployed into the right ventricle; deploying a proximal portion of the second tissue anchor at the second tissue location such that the proximal portion is deployed inside the right atrium; and plicating the tissue by changing the distance between the first and second tissue anchors.
