A bioabsorbable stent for placement at the locus of a stenotic portion of a body passage, such as a blood vessel, which is flexible and compliant for safe and effective delivery to the site of the stenotic portion of, for example, a blood vessel, and so as to avoid the disadvantages of chronic implantation, such as arterial rupture or aneurism formation while exposed to the continuous stresses of a beating heart. The stent is formed from a bioabsorbable material and is porous or has apertures defined there through to facilitate tissue ingrowth and encapsulation of the stent. The stent is encapsulated and biodegrades or bioabsorbs within a period of days, weeks or months as desired following encapsulation to thereby minimize the likelihood of embolization or other risks of the dissolved material and to avoid the disadvantages of chronic implantation.

A method of forming pores on the surface of a stent, the stent including a tubular main body portion having a first end, a second end, and a flow passage defined therethrough from said first end to said second end, said tubular main body portion being sized for intraluminal placement within a body passage, said main body portion being one of porous and apertured, at least in part, said main body portion being one of expandable and self-expanding from a first, reduced cross-sectional dimension to a second enlarged cross-sectional dimension whereby said main body portion can be transported intraluminally to a targeted portion of a body passage and expanded to a second enlarged diameter so as to engage and support said targeted portion of said body passage, the method comprising the steps of: i) contacting material from which said stent is formed with a solvent that swells said material under conditions such that swelling of an outer layer of said material is effected; and ii) contacting said material resulting from step (i) with an agent that is a nonsolvent for said material, which agent forms a solution with said solvent, under conditions such that said agent diffuses into said swollen outer layer of said material thereby causing phase separation and pore formation in said outer layer of said material.
