摘要： An apparatus and method is provided for stenting bifurcated vessels. A main-vessel stent and delivery system is provided for implanting a stent in the main vessel of a bifurcated vessel, wherein the main-vessel stent has an aperture bordered by closed stent cells that aligns with the opening to a side-branch vessel to permit substantially unobstructed blood flow between the main vessel and the side-branch vessel. The delivery system includes a catheter assembly having distal and proximal balloons separated by a positioning guide wire exit port located at the distal end of the catheter. The catheter assembly is advanced over a pair of guide wires for delivering, appropriately orienting, and implanting the main-vessel stent.

摘要： A serpentine coiled ladder stent (30) is provided, in which the coil is formed from a wound strip of cells (37), wherein the sides (34, 35) of the cells (37) are serpentine windings, wherein the strip is formed of at least two side bands (34, 35) connected to each other, for example by a series of cross struts (36). The cross struts (36) may be positioned slightly askew. Each side band (34, 35) is formed in a serpentine pattern comprising a series of bends (38), wherein upon expansion of the stent (30), the bends (38) of the side bands (34, 35) open to increase the length of each of the individual cells (37) in the helical direction, thereby lengthening the strip in the helical direction to allow the stent (30) to expand without any significant unwinding of the strip.

摘要： A radially expandible intra vascular stent (20) is provided with improved radially expandible strength due to increased amounts of metal surface area while flexibility is increased due to the unique stent wall surface pattern. In the un-expended form, the stent wall surface pattern (58) resembles a series of linked S-shapes (22) formed radially about the tube with interconnections (21) between the radial rows of S's (22) with alternating adjacent S's. Longitudinally, the un-expanded stent resembles longitudinal rows of pattern series of an S (24), S (24), reverse S (26), reverse S (26) shapes. This series repeats itself along the longitudinal surface of the stent. The longitudinal pattern is interconnected by the radial S's (21). When expanded for implantation within a lumen wall, the stent (20) unfolds to wall surface pattern (60) having linked parallelograms (52) along its longitudinal axis (40) while radially having alternating connected and disjoined struts forming a pattern similar to a butterfly shape (56), along its radial axis (50). The stent (20) can be non-uniform when expanded to accommodate the unique size and shape of the lumen into which it is implanted. The narrow outside diameter of the un-expanded stent eliminates the usual preliminary lumen expansion step. A multi-layer stent (70) is also provided. A method of implantation and a method of manufacture are also provided.

摘要： The invention is directed to an expandable stent (10) for implantation in a body lumen, such as an artery. The stent (10) consists of an elongated stent body formed with a central section (12) positioned between a proximal end section (14) and a distal end section (16), the central section (12) having different expansion characteristics than at least one of the end sections (14, 16). The end sections (14, 16) of the stent are configured to have greater resistance to radial expansion than the corresponding central section (12) such that, when deployed with a balloon catheter device, the central section (12) of the stent expands to an enlarged final diameter to contact the interior walls of the body lumen before or simultaneously with the end sections. The size and the shape of the U-shaped structures control the expansion characteristics of the respective cylindrical elements (18). The U-shaped structures which are designed to be more resistant to circumferential deformation are used to form cylindrical elements (18) that have a greater resistance to radial expansion. The cylindrical elements (18) are arranged strategically along the axial length of the stent (10) to form stent sections which cooperate to control radial expansion.
摘要翻译：本发明涉及用于植入诸如动脉的体腔内的可扩张支架（10）。支架（10）由细长的支架主体构成，该主体形成有位于近端部分（14）和远端部分（16）之间的中心部分（12），中心部分（12）具有不同于至少一个端部部分（14,16）。支架的端部部分（14,16）构造成比对应的中心部分（12）具有更大的径向膨胀阻力，使得当与球囊导管装置一起展开时，支架的中心部分（12）扩张到在终端部分之前或同时与体腔的内壁接触的放大的最终直径。 U形结构的尺寸和形状控制各个圆柱形元件（18）的膨胀特性。被设计成更耐周向变形的U形结构被用于形成具有更大阻抗径向膨胀的圆柱形元件（18）。圆柱形元件（18）沿支架（10）的轴向长度策略地布置，以形成协调以控制径向膨胀的支架部分。

摘要： An expandable stent for implantation in a body lumen, such as an artery, is disclosed. The stent consists of a plurality of radially expandable cylindrical elements generally aligned on a common longitudinal stent axis and interconnected by one or more interconnecting members placed so that the stent is flexible in the longitudinal direction. At least one end of the opposite ends of the stent has fewer interconnecting members than a center section of the stent to provide localized flexibility to a selected region of the stent.

摘要： The invention relates to a stent, specially a coronary stent, consisting of at least one thin-walled, tubular element with an openly reticular outer surface containing recesses, which are defined by narrow weblike elements. Said weblike elements are formed from the remaining material from the tube wall once the material has been removed from the recess area. The cross section of a weblike element is tapered in the proximity of the connection area with another weblike element in such a way that preferably a deformation comes about therein when the end of the weblike element that is distanced from the connecting area is deviated during expansion.
