1. An implantable frame defining a lumen extending between a proximal end and a distal end along a longitudinal axis, the implantable frame having a substantially cylindrical exterior surface area with a plurality of openings, the implantable frame moveable between a compressed state and an expanded state, the implantable frame comprising:

  • a plurality of longitudinally-spaced hoop members comprising a first hoop member and a second hoop member axially adjacent to the first hoop member; and

    a plurality of (n) longitudinal connecting members joining the first hoop member to the second hoop member, the plurality of (n) longitudinal connecting members comprising a first longitudinal connecting member closely-spaced with respect to a second longitudinal connecting member such that an angle less than (2π

    /n) radians is subtended by a hypothetical arc extending circumferentially along the exterior surface area of the implantable frame between a first radius extending from the longitudinal axis to the first longitudinal connecting member and a second radius extending from the longitudinal axis to the second longitudinal connecting member, where (n) is an integer equal to 2 or greater.
