Abstract:
1. An expandable stent and delivery system comprising: an elongated core member having proximal and distal sections; a proximal member radially extending from and disposed about the distal section of said core member; an intermediate member radially extending from and disposed about the distal section of said core member and generally positioned on said core member distally from said proximal member and spaced apart from said proximal member to form a gap having a longitudinal length; a positioning marker disposed about the distal section of said core member and generally positioned distal to said proximal member and having a longitudinal length; an expandable stent having a longitudinal axis, said stent including an anchor member attached to said stent and taking the form of an extension from an end of said stent and having a longitudinal length less than the longitudinal length of said gap and inwardly projected in a direction toward the longitudinal axis of said stent, said stent mounted on at least one member and positioned such that said anchor member interlocks within said gap; and a deployment catheter having a lumen extending therethrough and disposed about said core member such that said deployment catheter constrains said expandable stent about at least one member causing said anchor member to be maintained in said gap and thereby causing said stent to be interlocked onto said core member.
