Expandable stent with markers and stent delivery system

An expandable stent and stent delivery system comprising:

• a delivery system including an elongated core member having a distal portion, a proximal cylindrical member disposed about the distal portion of said elongated core member, and a distal cylindrical member disposed about the distal portion of said elongated core member and generally positioned distally from said proximal cylindrical member and spaced apart from said proximal cylindrical member to define a gap having a longitudinal length;
• an expandable stent comprising a small diameter skeletal tubular member having a thin wall, said wall of said tubular member being cut to define a plurality of cells which are formed by a plurality of interconnected strut members, a first one of said plurality of strut members having threads cut into an edge of said first strut member, a coil being wound onto said threads of said first strut member to thereby define an anchor member, said anchor member having a longitudinal length no greater than the longitudinal length of said gap, and said expandable stent being mounted on at least one cylindrical member and positioned such that said anchor member is disposed within said gap;
• and,
• a deployment catheter having a lumen extending therethrough and disposed about said elongated core member such that said deployment catheter compresses said expandable stent about at least one cylindrical member causing said anchor member to be retained in said gap and thereby causing said expandable stent to be interlocked onto said elongated core member.

An expandable stent comprising:

• a small diameter skeletal tubular member having a thin wall;
• said wall of said tubular member including a plurality of cells which are formed by a plurality of interconnected strut members, a first one of said plurality of strut members being formed with a threaded portion on said first strut member;
• and,
• a radiopaque marker, which takes the form of a coil being wound onto said threaded portion of said first strut member
• in which a second one of said plurality of strut members is formed to create a threaded portion on said second strut member includes a marker, being wound onto said threaded portion of said second strut member.

An expandable stent comprising:

• a small diameter skeletal tubular member having a thin wall;
• said wall of said tubular member including a plurality of cells which are formed by a plurality of interconnected strut members, eight of said plurality of strut members being formed with a threaded portion on each of said eight strut members;
• and,
• eight markers, which take the form of a coil being wound onto each threaded portion of said eight strut members.

• a coil being wound onto said threads of said first strut member.

An expandable stent comprising:

• a small diameter skeletal tubular member having a thin wall;
• said wall of said tubular member being cut to define a plurality of cells which are formed by a plurality of interconnected strut members, eight of said plurality of strut members having threads cut into two opposing edges of said eight strut members;
• and
• eight markers, which take the form of a coil being wound onto each of said threads of said eight strut members.
