Patent number: 7070617Abstract: A stent is made flexible along its length. The stent initially starts as a metal sheet. It is rolled in its central region to a specified wall thickness. Thereafter, the stent is photochemically etched to produce the desired cell pattern of the design of the stent. Then, the stent is folded and the metal is joined to give rise to a stent with multiple wall thickness. For instance, larger wall thicknesses at the end of the stent versus smaller wall thicknesses at its center. Various other possible manufacturing methods are useful with respect to this stent.Type: GrantFiled: July 1, 2004Date of Patent: July 4, 2006Assignee: Cordis CorporationInventors: John S. Kula, James E. Umbach, Andreina Gomez

Publication number: 20060052860Abstract: The invention is directed to an expandable stent for implanting in a body lumen, such as a coronary artery, peripheral artery, or other body lumen. The invention provides for an intravascular stent having a plurality of cylindrical rings connected by undulating links. The stent has a high degree of flexibility in the longitudinal direction, yet has adequate vessel wall coverage and radial strength sufficient to hold open an artery or other body lumen. The stent can be compressed or crimped onto a catheter to a very low profile since the peaks that are adjacent the curved portion of the undulating link are shorter than other peaks in the same cylindrical ring to prevent overlap yet still achieve a very low profile, tightly crimped stent onto a catheter.Type: ApplicationFiled: August 31, 2005Publication date: March 9, 2006Inventors: Andreina Gomez, Diem Ta

Patent number: 6979349Abstract: The present invention provides an improved stent design for repairing a vessel. The stent design incorporates crimpable, short non linear links which are flexible in three dimensions and which include flexible arms. The ability to accommodate both small deformations that occur during delivery and larger deformations that occur upon expansion within the vessel is enhanced without sacrificing stent crimp diameter. The link may incorporate a short flexible link with a perpendicular transition to provide added flexibility.Type: GrantFiled: August 14, 2003Date of Patent: December 27, 2005Assignee: Advanced Cardiovascular Systems, Inc.Inventors: Kenny L. Dang, Andreina Gomez, Su-Wen Ueng
