Barbed anchor

An endoluminal prosthesis includes a support structure including a curvilinear portion (85) having a first strut (82) and a second strut (88) that meet at an apex (83). Disposed on the support structure is an anchor (120; 220; 320) with an anchor body (125; 225) and one or more barbs (121a, 121b; 22...

More Information
Summary:An endoluminal prosthesis includes a support structure including a curvilinear portion (85) having a first strut (82) and a second strut (88) that meet at an apex (83). Disposed on the support structure is an anchor (120; 220; 320) with an anchor body (125; 225) and one or more barbs (121a, 121b; 221a, 221b; 326) extending outwardly from the anchor body (125; 225). The anchor body (125; 225) can fit at least partially about, and can conform to the first strut (82), second strut (88), and the apex (83). A curved portion (134; 234) of the anchor (120; 220; 320) and the curvilinear portion (85) of the support structure can be co-formed, resulting in a secure interference fit so that welding, soldering, or other joining mechanisms can be avoided. Cutouts (150; 250; 260) can be formed along the curved portion (134; 234) of the anchor (120; 220; 320) to relieve stress or strain during the co-forming process.
