Abstract:
1. A stent comprising: a plurality of arcuate sections circumscribing a longitudinal axis from a first portion to a second portion to define a portion of a tube, the plurality of arcuate sections spaced apart along the longitudinal axis to form at least one continuous helical path about the longitudinal axis from the first portion to the second portion, each arcuate section including a plurality of struts that extend in different directions with respect to the longitudinal axis; and at least one connector connecting at least one of the plurality of struts of one arcuate section to at least one of the plurality of struts of an axially spaced adjacent arcuate section, the at least one connector made from a material that is bioresorbed upon exposure to biological tissue or fluid such that the stent has a first spring constant in an unimplanted condition and a different second spring constant in an implanted condition after a period of time, and such that the at least one continuous helical path is maintained after the material is bioresorbed.
