Tissue restraining devices and methods of use

摘要

Tissue restraining systems and devices as well as methods of using these devices are disclosed herein. According to aspects illustrated herein, there is provided a tissue restraining device that may include an annuloplasty member having one or more contact points along a portion of the annuloplasty member in a spaced relation to one another. The tissue restraining device may also include a second anchor for placement in a substantially opposing, spaced relation to the annuloplasty member. A restraining matrix may extend from the contact points of the annuloplasty member to the second anchor.

主权项

1. A tissue restraining device comprising:
an annuloplasty member for attachment to a valve annulus of a cardiac valve, the annuloplasty member defining an opening; an anchor having a loop and situated in a spaced relation to the annuloplasty member on an opposite side of the cardiac valve; a plurality of restraining cords forming a restraining matrix extending from the annuloplasty member into the opening and toward the anchor so that when the tissue restraining device is implanted, the restraining matrix is draped over a leaflet of the cardiac valve, the restraining cords converging at their distal ends to form an apex between the annuloplasty member and the anchor; and a tensioning strand extending distally from the apex of the restraining matrix, passing through the loop, and extending through the annuloplasty member so the restraining matrix is adjustable as a single unit to change a tension in the restraining matrix.
