Patent ID: 7918884

Claim:
A stent comprising: a lattice defining a substantially cylindrical configuration having a proximal end section and a distal end section, and a middle section between the proximal end section and the distal end section, the lattice being movable from a crimped state to an expanded state, the lattice having a plurality of adjacent hoops; a plurality of bridges connecting adjacent hoops; a plurality of extensions on the lattice; the extensions comprise a center arm terminating in a bifurcation; each of the hoops and bridges defining a cell, the extensions having one end integrally formed with the lattice and another end extending into the cell; and the proximal end section and the distal end section of the lattice having at least one cell respectively and the middle section of the lattice having at least one cell, the at least one cell of the middle section having spacing between adjacent hoops that is greater than spacing between adjacent hoops of the at least one cell of the proximal end section and the distal end section respectively.
