Exclusion device beams and related methods

A method of making an exclusion device for an anatomical structure, the method comprising:

• obtaining a first beam, a second beam, and a first spring, where the first beam and the second beam each having a dominant beam longitudinal dimension;
• operatively coupling the first spring to the first beam and to the second beam to bias the first beam toward the second beam along a first direction so the first beam predominantly longitudinally overlaps the second beam and allows the first beam to be repositionable with respect to the second beam along the first direction, where a minimum spacing between the first beam and the second beam coincides with a first overall longitudinal length of the exclusion device, and wherein a spacing greater than the minimum spacing between the first beam and the second beam coincides with a second overall longitudinal length of the exclusion device less than the first overall longitudinal length.
