Abstract
The invention relates to an implantable medical stent having a low profile for delivery through smaller lumens. The stent is constrained during delivery where the helically wrapped points of a diamond cell structure also include at least one crossed joint of intersecting strands to provide a reduced diameter.
Claims23
A medical stent comprising a first tubular body including a first plurality of strands that intersect at helically wrapped joints along the tubular body, the strands also intersecting at a plurality of crossed regions without being helically wrapped at the crossed regions, the tubular body being expandable from a constrained state to an expanded state and having a diameter of 8 French or less in the constrained state.
A method of delivering a stent to a site within a body lumen comprising:
- providing a catheter having a distal end and a proximal end, the stent being positioned at the distal end within a moveable sheath and having a plurality of strands intersecting at helically wrapped joints and also intersecting at crossed regions at which the strands intersect without being helically wrapped, the diameter of the stent within the sheath being 8 French or less;
- delivering the distal end of the catheter to a site within the body lumen;
- and
- moving the sheath to expose the stent such that the stent expands to contact a surface of the lumen.
