Claim 17:
18. A medical device comprising:
a device body comprising a first section, two or more second sections connected to one end of the first section, and a third section connected to the other end of the first section distal to the first section, wherein, in a first configuration of the device body, the device body has a longitudinally extending configuration, and wherein, in a second, 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 defines a plurality of second section loops forming a three-dimensional non-helical structure,
each second section has a maximum cross-sectional dimension that is smaller than a maximum cross-sectional dimension of the first section, and
the third section defines a third section loop configured to exert a larger radial force against a vessel wall compared to at least one of the first or second sections, the third section loop being larger than at least one first section loop of the plurality of first section loops,

wherein the device body defines a longitudinal axis extending in a direction from the third section to the two or more second sections, and
wherein the two or more second sections are spaced from each other along the longitudinal axis, such that at least one second section trails another second section.
