Expandable implant and implant system

A system comprising:

• a backbone, coupled to a pusher wire, the backbone including primary and secondary states;
• and
• a monolithic shape memory polymer (SMP), covering a majority of the backbone, the monolithic SMP including:
• (a) (i) primary and secondary states, (a) (ii) first and second portions, and (a) (iii) a first joint located between the first and second portions;
• wherein (b) (i) in a first configuration the backbone is coupled to the pusher wire, the monolithic SMP and the backbone are both in their respective secondary states and configured to be advanced through vasculature, and the first and second portions are generally collinear with one another;
• and (b) (ii) in a second configuration the backbone is decoupled from the pusher wire, the monolithic SMP and the backbone are both in their respective primary states and configured to both be included in an aneurysm, and the first and second portions are non-collinear with one another based on the first portion pivoting about the first joint relative to the second portion.
