A method for forming a stent in situ involves manipulating a delivery
system to provide a mold within a lumen of a living body, and injecting a
settable, biocompatible phase invertible composition into the mold. After
the biocompatible phase invertible composition is set, the delivery
system is removed. The stent provides a micro-porous support structure
with good tensile strength that is adhesively bound to the lumen. The
biocompatible phase invertible composition may be a composition concocted
from albumin and collagen, for example, and may be infused with an
anti-restenosis agent.
