摘要： A stent (10) formed from cannula and having flexible segments (11) and high hoop strength segments (12) alternating therealong. Axial tie bars (21,22) interconnect the segments; minimal length reduction would occur upon expansion. In the high hoop strength segment (12), struts (16) are initially parallel in the unexpanded strut condition, while in the flexible segment (11), struts (14) extend from a respective bight (15) to converge at distal ends when unexpanded. In one embodiment, certain adjacent struts (16) of the hoop segment are spaced apart by a large gap (20) while others are spaced apart by a small gap (18). In another embodiment all the struts (16) of the hoop segment are spaced apart uniformly from each other (or from an axial tie bar) by a small gap (23), resulting in minimizing the occurrence of fatigue of high-stress sites upon expansion/contraction cycles from continuous pulsatile events.

摘要： An expandable endovascular stent comprises a flexible, tubular body (1) with a longitudinal axis, the wall of which is formed by interconnected, closed lattice cells (2) arranged with at least two cells adjacent to each other in the circumferential direction. Filament-shaped lattice material capable of transmitting compressive forces in the axial direction of the filament extends continuously from one lattice cell directly into the lattice cell following in the longitudinal direction. The stent can be expanded from a radially compressed state into a radially expanded state having a larger diameter. In the expanded state of the stent, the pressure transmitting lattice material in several of the lattice cells (2) forms a heart-like or arrowhead-like shape with at least two interconnected diverging, angle .beta. cell sides (5) positioned opposite to and interconnected with at least two mutually converging, angle .alpha. longer cell sides (3). For stability during expansion and compression of a self-expanding stent, the sum of the first angle .alpha. and the second angle .beta. should be in the range of 345.degree. to 360.degree., preferably at 360.degree. to maintain a constant axial stent length.
摘要翻译：可扩张的血管内支架包括具有纵向轴线的柔性管状体（1），其壁由相互邻近的至少两个细胞在圆周方向上布置的互连的闭合晶格单元（2）形成。能够沿着灯丝的轴向传递压缩力的丝状网格材料在纵向方向上从一个晶格单元直接延伸到晶格单元中。支架可以从径向压缩状态扩展到具有较大直径的径向膨胀状态。在支架的膨胀状态下，几个晶格单元（2）中的压力传递晶格材料形成心形或箭头状形状，其具有至少两个相互连接的发散的角β单元侧（5）与至少两个相互收敛的角度α更长的单元侧（3）相互连接。对于自扩张支架的膨胀和压缩期间的稳定性，第一角度α和第二角度β的总和应在345°至360°的范围内，优选在360°，以保持恒定的轴向支架长度。

摘要： A stent structure (30) particularly for use in treating cerebral aneurysms is provided with a fibrous coating (34) which reduces the permeability of the underlying stent (32) to an extent that the flow through the stent structure is sufficiently suppressed to allow for resorbtion of an aneurysm while still providing sufficient flow through the stent structure to allow for flow into the perforator vessels. The fibrous coating may have different permeabilities in different zones of the underlying stent (32). The coating could be applied to other devices such as filters and occluders.

摘要： A deployment assembly (10) for an introducer used for introducing into a patient a stent or other device, the deployment assembly including a housing 30 carrying a sprung loaded (90) actuator (44,50). The actuator includes a toothed wheel (50) carrying a spool (48) around which a retraction strap (44) can be wound. The strap (44) is coupled to a body member (26) of the introducer and through this to the outer sheath (14) thereof. A trigger (16) is provided for operating the actuator (44, 50). When the trigger (16) is pressed, the actuator winds, under the force produced by the spring (90), the strap (44) to thereby retract the outer sheath (14) so as to expose and then deploy the device carried on the introducer. The mechanism is such that a surgeon need not expend his own energy to retract the outer sheath (14) since this force is provided by the spring (90). Furthermore, the spring (90) acts in a plane other than that of the direction of retraction of the sheath (14), which minimizes the risk of inadvertent movement of the introducer as the sheath (14) is being retracted.

摘要： A stent (10) is provided with a plurality of stent rings (12) formed of a plurality of interconnected struts (14). Adjacent stent rings (12) are coupled to one another by a plurality of tie bars (16). Within each tie bar (16) there is provided a hinge (36) which facilitates the curving of the stent (10) in its longitudinal direction and minimizes the generation of returning force to a non-curved configuration by the stent (10). The hinge could, for example, be formed by heat treating a portion of the tie bar (16). This arrangement is particularly suitable for stents or other medical devices intended to be placed in delicate vessels, such as cerebral vessels.

摘要： A rapid exchange balloon catheter having a proximal end and a distal end, said catheter comprising: a tubular metal shaft body extending from the proximal end along a majority of the total length and having an inflation lumen arranged therein, a plastics distal end portion bonded to the metal body in extension thereof, said distal end portion being provided with an inflation lumen in communication with a balloon, and a guide wire lumen, said guide wire lumen extending from a proximal side port to a distal end opening. To reduce the resistance to kinking, the metal body comprises a transitional region having reduced stiffness at the position of bonding to the plastics distal end portion compared to a more proximal position along the metal body.

摘要： A prosthesis (110) comprises a plurality of stent members which are formed of strut elements (120) connected by apexes, wherein at least the proximal apexes of the first stent member or the distal apexes of the second stent member have a shaped portion which is flat or concave. The proximal apexes (122) of a first stent member (116a) are arranged to engage the distal apexes (124) of an adjacent second stent member (116b) when the prosthesis is subjected to longitudinal compression forces. The shaped portion of the apexes prevents interdigitation of the stent members, which could lead to lateral deflection of the prosthesis.
