Patent ID: 8414638

Claim:
A method of fabricating a stent comprising: crimping a polymer stent to a reduced profile onto a balloon catheter, wherein the stent is constructed of a pattern of a plurality of polymeric structural elements, wherein as the stent is crimped below the glass transition temperature of the structural elements, the structural elements plastically deform resulting in a gripping force on the balloon catheter by the crimped stent, wherein the gripping force retains the crimped stent on the balloon catheter at the reduced profile that is not sufficient to prevent the stent from shifting position or separating from the catheter prior to delivery; and followed by forming at least one breakable connecting element between two structural elements to facilitate retention of the stent at a reduced diameter so that the stent does not shift position or separate from the catheter prior to delivery, wherein upon expansion of the stent the at least one breakable connecting element breaks to allow expansion of the stent due to a radially outward force on the stent, wherein the forming comprises fusing the two structural elements together, wherein the connecting element is formed while the stent is crimped.
