Abstract
A seamless, self-expanding implantable device having a low profile is disclosed along with methods of making and using the same. The implantable device includes a frame cut out of a single piece of material that is formed into a three-dimensional shape. The implantable device may comprise an embolic filter, stent, or other implantable structure. The present invention also allows complicated frame structures to be easily formed from planar sheets of starting material, such as through laser cutting, stamping, photo-etching, or other cutting techniques.
