  • Patent number: 10939906
    Abstract: The present invention includes a suture article and a suture placement device adapted to insert into opposing tissue surfaces the anchors of a suture article having anchors on its terminal ends, the device comprising in general terms: (a) an optional handle portion; (b) an insertion portion extending from the handle having a distal end comprising anchor-directing portions that diverge from one another so as to form a V-shape, adapted to releasably engage the anchors; and (c) a hollow cinching cannula/suture conduit slidingly engaged by the handle portion so as to be moveable between a position relatively nearer the handle and a position relatively nearer the insertion portion distal end.

  • Publication number: 20180193014
    Abstract: The present invention includes a braided suture article adapted to be inserted through or into a tissue so as be able to exert a force on that tissue, the braided suture material adapted to be moved from an extended configuration to a collapsed configuration forming at least two loops extending substantially perpendicular to its threaded length and having a relatively rigid terminal end length that extends substantially perpendicular to the threaded length. The present invention further includes a suture placement device adapted to insert a length of suture material into or through a tissue to a space beyond a rear surface of said tissue so as to maintain said length of suture material, and a method of placing an expanding suture knot into a tissue.
