摘要： This invention relates generally to expandable intraluminal medical devices for use within a body passageway or duct, and more particularly to an optimized stent having asymmetrical strut and loop members. In one embodiment of the invention the stent includes one or more members each having at least one component. The component has non-uniform cross-sections to achieve near-uniform stress distribution along the component when the component undergoes deformation.

摘要： Accordingly, it is a object of the invention to create a stent which comprises structurally strong radial rings which are connected by structurally weak connectors. These connectors then separate within the body so that they are able to cause the stent to be emplaced exclusively at selected points within the lumen with a clear separation made between each of these radial rings.

摘要： In accordance with the present invention, there is provided a stent for insertion into a vessel of a patient the stent is a tubular member with a predetermined a thickness. The member has front and back open ends and a longitudinal axis extending therebetween. The stent has a first smaller diameter for insertion into the vessel, and a second larger diameter for deployment into the vessel. The tubular member includes a plurality of adjacent hoops extending between the front and back ends. The hoops are made from a plurality of longitudinal struts and a plurality of loops connecting adjacent struts. The member further includes a plurality of bridges connecting adjacent hoops to one another. The individual struts have lengths, as measured parallel to the longitudinal axis. The stent is constructed so that the ratio of the number of struts per hoop to the length of a strut, as measured in inches, is greater than about 400.

摘要： A composite stent device comprises a shape memory alloy stent sleeve which is treated so that it can exert an outward force on a lumen in which the stent device is to be deployed, and a restraint element which restricts the maximum transverse dimension to which the stent sleeve can expand outwardly. The restraint sleeve can minimize damage to a lumen by a stent located within it. It can be arranged to allow the stent device to be deformed in a bending mode, for example when the lumen in which the device is located is subjected to a transverse flattening deformation, relying on the enhanced elastic properties of the shape memory alloy stent sleeve to recover to the open, generally rounded configuration.

摘要： A composite material in rod, tube, strip, sheet or plate shape with reversible thermomechanical properties is produced by joining of at least two parts consisting of a total of at least one shape memory alloy having a two-way effect, whereby each part has a memory effect by itself. In the case of at least two shape memory alloys (1, 2) with different transition temperatures but the same mode of movement, the joining of the individual parts can take place prior to the deformation in the low temperature range necessary to inducing the two-way effect. In the case of differing types and degrees of movement of the individual parts (25, 26), their joining can first be accomplished only after the individual deformations of each part for itself in the low temperature range are accomplished regardless of how many shape memory alloys with different transition temperatures are used in the structure of the composite material.

摘要： A delivery apparatus including an outer sheath, made from an elongated tubular member having distal and proximal ends. The apparatus further includes a self-expanding stent located within the distal end of the sheath along a load area. The stent makes frictional contact with the inner layer of said sheath. Lastly, the apparatus includes a readily removable member or keeper, which is disposed along the outer sheath along at least a portion of the load area. The member has sufficient rigidity to prevent the outer sheath from expanding along the load area prior to delivery of the stent.

摘要： A noticeable two-way effect can be induced in a component consisting of a shape memory alloy exhibiting only a one-way effect by inhomogeneous deformation of the cross-section so that one part of the component cross-section is deformed sufficiently to hinder the free movement of the one-way effect in the lesser deformed part.

摘要： A stent having marker tabs formed from a micro-alloyed combination of materials provides for more precise placement and post-procedural visualization in a vessel, by increasing the radiopacity of the stent under X-ray fluoroscopy. A unique micro-alloying process is utilized to form the tabs, comprising a first alloy and a second alloy, wherein one of these alloys is radiopaque. This substantially eliminates the possibility of galvanic action between the tab and the stent. This process is also applicable to other medical devices.
