Stents that are adapted to be balloon-expanded and include a plurality of rings of repeating cells, wherein adjacent rings are connected by s-shaped or omega-shaped crosslink connectors or a combination of both connectors. The configurations, materials, and/or dimensions of these devices, including the unit cells and/or crosslink connectors allow the stents to be expanded to a greater extent (e.g., up to or greater than 12 mm of diameter), and optionally with reduced foreshortening and without increasing the strain on the materials forming the crosslink connectors and unit cells. The biphasic arrangement of trapezoidal unit cells, as well as the configuration and arrangement of the s-shaped connectors, may allow these stents to expand while maintaining their radial compression strength and longitudinal compression strength with minimal recoil and stent foreshortening.

A stent assembly comprises a stent formed by a network of struts, the stent having an internal surface and an external surface, a covering material covering at least a transverse section of at least one of the internal surface and the external surface, and a polymer binder mediating between the struts and the covering material to bind therebetween. The polymer binder encapsulating at least 80%, by length, of the combined lengths of the struts of the network within the transverse section to a first binder thickness. The polymer binder selectively has a second binder thickness that is at least twice the first binder thickness at multiple binder-locations circumferentially-displaced along a circumference of the transverse section and occupying in aggregate, at least 5% and not more than 75% of the circumference with no location-location spacing being greater than one-third of the circumference.

A stent for use in a medical procedure having opposing sets of curved apices, where the curved section of one set of apices has a radius of curvature that is greater than the curved section of the other set of apices. One or more such stents may be attached to a graft material for use in endovascular treatment of, for example, aneurysm, thoracic dissection, or other body vessel condition.

This invention is directed to an expandable stent for implantation in a body lumen, such as an artery, and a method for making it from a single length of tubing. The stent consists of a plurality of radially expandable cylindrical elements generally aligned on a common axis and interconnected by one or more links. A Y-shaped member is comprised of a U-shaped member and a link having a curved portion and a straight portion to improve the flexibility and thereby improve the fatigue performance of the Y-link junction.

A flow diverter including a self-expanding tubular member having a plurality of expandable cells, each of the expandable cells having interconnected struts and bridges. The tubular member has a constrained configuration having a first outer diameter of at least 1.0 mm sized for delivery using a flow diverter delivery system and an expanded configuration having a second outer diameter larger than the first outer diameter. The tubular member has a proximal end zone, a distal end zone, and a middle zone located between the proximal end zone and the distal end zone. At least the middle zone of the tubular member is laser-cut to have a material coverage of at least 25% when the tubular member is in the expanded configuration. Related devices, systems, and methods of treating disease, particularly intracranial and cerebral aneurysms by deploying implantable expandable devices, are provided.

Disclosed is an injection molding method for a degradable intravascular stent with a flexible mold core structure. The injection molding method includes the following steps: Step 1, winding a metal rod with a flexible metal film, and applying an inward bending stress to the flexible metal film; Step 2, fixing the flexible metal film to the metal rod, and processing a complementary structure of the degradable intravascular stent on the surface of the flexible metal film; Step 3, performing injection molding processing; Step 4, ending the injection molding, removing the mating body of the flexible metal film and the metal rod and the degradable intravascular stent formed on the surface of the flexible metal film by injection molding, performing cooling, separating the metal rod from the flexible metal film, withdrawing the metal rod, and then removing the flexible metal film to obtain a formed degradable intravascular stent.

Apparatus and methods are described, including a stent configured to be placed in a lumen. The stent includes a generally cylindrical stent body including a plurality of struts, at least one electrode post protruding from the stent body, and a plurality of antenna posts protruding longitudinally from an end of the stent body. The antenna posts are longitudinally separated from the electrode post. An antenna is disposed annularly on the antenna posts, such that the antenna posts separate the antenna from the end of the stent body, and at least one electrode is coupled to the stent by being placed on the electrode post. Additional embodiments are also described.

An implant includes a tubular discontinuous structure formed of a plurality of webs that at least partially extend in a longitudinal direction. The plurality of webs includes at least one joint element having a main web substantially extending in the longitudinal direction. There is a continuous gap in the main web. At least one bridge web is arranged next to the main web in a circumferential direction (U) and connected to the main web in the longitudinal direction (A) in front of and behind the gap.

A stent includes a high radial/crush force segment and a highly flexible segment. In an aspect, a plurality of first ring struts connected such that each of the plurality of first rings comprises a sinusoidal pattern having a plurality of apices and troughs, each first ring connected to an adjacent first ring by at least one connector. The connector extends from a ring strut of the first ring from a position near an apex of the first ring to a ring strut of the adjacent first rings near an apex of the adjacent ring, and a second stent segment comprises a plurality of second rings connected to one another to form a series of second rings

A stent made from a material comprising a polymer is disclosed. The stent has a pre-crimp diameter and a wall thickness such that a ratio of the pre-crimp diameter to the wall thickness is between 30 and 60. The stent has a pattern of interconnected elements. The interconnected elements including a plurality of rings connected by links, wherein each ring includes struts and crowns, and the struts are configured to fold at the crowns when the stent is crimped to the balloon.
