20100161034 | STENTS WITH ATTACHED LOOPED ENDS - An open frame prosthesis is formed with looped end terminations at its proximal and distal ends. At one end of the prosthesis, the filaments or strands are welded together in pairs to form strand couplings. A plurality of loop segments are connected to the strand couplings, one loop segment for each pair of adjacent strand couplings. In one version of the prosthesis, strands at the opposite end are bent to form looped ends. In another version, loop segments are connected to pairs of strand couplings at both ends of the prosthesis. The loop segments can be connected to the couplings by welding, fusion bonds, or tubes, which are either crimped or heat shrunk. | 06-24-2010 |
20110265908 | APPARATUS AND METHOD FOR MANUFACTURING A SINGLE WIRE STENT - A mandrel for manufacturing a stent from a single wire includes a cylindrical member having a plurality of pins at a proximal end region, a plurality of pins at a distal end region, and a plurality of indentations between the proximal pins and the distal pins. These indentations form a helical pattern on the outer surface of the cylindrical member. The single wire is wrapped around every proximal pin and distal pin on the mandrel by following the indentations in the mandrel. The single wire is slid through the indentation under any crossing section of wire and over the next crossing section of wire in an under-over pattern. | 11-03-2011 |

20130190758 | MEDICAL DEVICES WITH MULTIPLE DEGREES OF FREEDOM AND RELATED METHODS OF USE - Embodiments of the disclosure are directed to a medical device. The medical device may include a shaft having a proximal end and a distal end. A positioning mechanism may be disposed adjacent the distal end of the shaft. The positioning mechanism may include an outer member and an inner member coupled to an end-effector. The outer member may be pivotably attached to the distal end of the shaft and the inner member may be pivotably attached to the outer member. | 07-25-2013 |
20130269506 | Atraumatic Stent and Method and Apparatus for making the same - A method of braiding a stent includes braiding a number of elongate filaments around a mandrel using tensioned braiding carriers without spooling the filaments to the tensioned braiding carriers to form a braided stent having atraumatic ends. | 10-17-2013 |
20140074220 | Stent With Reduced Weld Profiles and a Closed-End Wire Configuration - A prosthesis including a composite wire forming a mesh, the mesh having a variable diameter wherein at least one end region has a larger diameter than a middle portion; the mesh having an exterior surface and an interior surface, wherein at least one of the surfaces is covered with silicone; and a retrieval loop positioned at at least one end of the mesh. | 03-13-2014 |
