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, each of the plurality of arcuate sections including an expandable section that provides radial expandability to the arcuate section such that the plurality of arcuate sections have an unexpanded insertion size and a larger expanded size, the expandable section including a plurality of struts that extend in different directions with respect to the longitudinal axis of the stent, the expandable section further including a peak and a trough arranged between three individual struts of the plurality of struts; and at least one connector connecting one of the plurality of struts of one arcuate section to one of the plurality of struts of an axially spaced adjacent arcuate section, the at least one connector being made from a material that is bioresorbed upon exposure to biological tissue 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 predetermined period of time.
