Intraluminal stents
First Claim
1. A radially expandable intraluminal stent in the form of a generally tubular wall having open regions that define wall structure comprising:
- a plurality of nodes, each node having a central hub and only three arms extending from the hub, each arm being curved and circumscribing the hub and a segment of an adjacent arm of that node;
each arm being connected, at a transition region, only to a single arm of an adjacent node, the connected arms of adjacent nodes defining an S-shaped link between those nodes.

Abstract
An intraluminal stent placeable in the lumen of the human body. Includes a generally tubular wall having a filigree-like pattern of interconnected links and open work. The pattern includes nodes that have a central hub and three arms connected to the hub. The arms are arranged circumferentially about the hub and lie adjacent the next adjacent arm of the node in a spiral-like fashion. The arms are connected to other components of the stent which, themselves, may comprise other nodes. The nodes are arranged in repeatable clusters. The disclosure also relates to a technique for making a stent and for mounting a stent on a delivery catheter by which the stent may be crimped onto the catheter in its lowest profile configuration.

25. A radially expandable intraluminal stent in the form of a generally tubular wall having open regions that define wall structure comprising:
- a plurality of nodes, each node having a central hub and only three arms extending from the hub, each arm having a root and being curved and circumscribing the hub and a segment of an adjacent arm of that node and lying closely adjacent the segment;
each arm being connected, at a transition region only to a single arm of an adjacent node, the connected arms of the adjacent nodes defining a link between those nodes, the link extending from the root of one of the connected arms to the root of the other, wherein the link curves in one direction from one root to the transition region and in an opposite direction from the transition region to the other root.
- a plurality of nodes, each node having a central hub and only three arms extending from the hub, each arm having a root and being curved and circumscribing the hub and a segment of an adjacent arm of that node and lying closely adjacent the segment;
- 26. In a radially expandable tubular intraluminal stent defined by and having a plurality of interconnected members deformable to a larger diameter tubular configuration, the improvement comprising a plurality of nodes, each defined by a central hub and only three arms, each of the arms in each of the nodes being curved and having a portion that circumscribes the hub and a segment of an adjacent arm of that node and lies closely adjacent the segment, the stent being defined substantially entirely by said nodes, each arm being curved and being connected at a transition region to a single arm of an adjacent node, the connected arms of adjacent nodes defining an S-shaped link between those nodes.

33. A radially expandable intraluminal stent in the form of a generally tubular wall having cut out regions that define wall structure comprising:
- a plurality of nodes, each node being connected only to three adjacent nodes, each by an individual generally S-shaped link, some of which are circumferentially oriented;
the links and nodes being arranged so that when the stent is expanded from its initial diameter to an expanded diameter, circumferentially oriented links will elongate to a greater degree than links oriented in a less circumferential direction.
- a plurality of nodes, each node being connected only to three adjacent nodes, each by an individual generally S-shaped link, some of which are circumferentially oriented;

34. In a radially expandable tubular stent having a wall defined by and having a plurality of interconnected links deformable from a low profile diameter to an expanded diameter, the improvement comprising a plurality of nodes, each node having a central hub and only three arms extending from and circumscribing the hub and a segment of an adjacent arm of that node, the arms being of sufficient length to flex to permit the central hub to be displaced transversely with respect to those regions of the stent wall that surround the transversely displaced hub, each of the arms being connected to an arm of an adjacent node to define an S-shaped link.
