Abstract
An intraluminal prosthesis composed of a self-expandable stent and a biodegradable constraining element being capable of biodegrading in vivo over a predetermined period of time to permit radial expansion of the stent. The constraining elements are applied to the stent to produce a compressed configuration. Dissolution of the constraining elements in vivo allows for expansion of the stent to an expanded configuration.
Claims11
A method of repairing a diseased tubular organ comprising the steps of:
- a. providing a radially self-expanding tubular stent defining a lumen therein comprising first and second ends and a medial portion therebetween;
- b. placing a biodegradable constraining element on said stent to constrain said medial portion of said stent to maintain said stent in a compressed state and preventing said stent from diametrically changing to a radially expanded state;
- and
- c. implanting said stent into said diseased tubular organ.
