1. A medical device comprising:
a device body comprising:
a first section;
a plurality of second sections; and
a third section connected to the first section on an opposite side of the first section from the plurality of second sections,
wherein the device body defines a longitudinal axis extending in a direction from the third section to the plurality of second sections, and
wherein, in a deployed configuration of the device body:
the first section defines a plurality of first section loops forming a three-dimensional non-helical structure configured to anchor the device body in vasculature of a patient,
each second section of the plurality of second sections defines a plurality of second section loops forming a three-dimensional non-helical structure, the three-dimensional non-helical structure of each second section being an approximately polyhedral structure having three or more sides,
each second section of the plurality of second sections has a maximum cross-sectional dimension that is smaller than a maximum cross-sectional dimension of the first section, and
the third section forms a different sized and shaped structure than the three-dimensional non-helical structures formed by the first and second sections and defines a third section loop larger than at least one first section loop of the plurality of first section loops.
