Abstract
A method is provided for forming a stent within a body lumen. According to the method, a distal catheter body is advanced within a body lumen to a section of a body lumen at which a stent is to be formed. One or more expandable members attached to the distal catheter body are expanded such that sections of the body lumen proximal and distal to the stent formation section of the body lumen are occluded, the distal catheter body in combination with the body lumen defining a mold space. A fluent pre-stent composition is delivered to the mold space from outside the body lumen which is continuously in fluent state during pre-stent composition delivery from outside the body lumen to the mold space. The fluent pre-stent composition is then transformed within the mold space to a non-fluent stent composition to form a stent within the mold space.
