Abstract
A method of making an endovascular prosthesis comprises the steps of applying a first layer of polymer to a portion of a deformable matrix, contacting a stent with the polymer to deform the matrix, applying a second layer of polymer over at least a portion of the stent and first layer, solidifying the layers of polymer to form the endovascular prosthesis, and removing the matrix.
Claims17
A method of making an endovascular prosthesis having a desired shape comprising:
- applying a first layer of polymer onto a portion of a deformable forming member;
- contacting a stent with the polymer to deform the forming member;
- applying a second layer of polymer over at least a portion of the stent and first layer;
- solidifying the layers of polymer to form the endovascular prosthesis;
- removing the forming member;
- and
- wherein the deformable forming member exhibits plasticity during application of the polymer layers and stent.
