1. A filter comprising:
- a seamless frame having a proximal end and a longitudinal axis, said frame having a seamless support member circumscribing said axis and distally spaced from said proximal end, said support member having at least one attachment strut seamlessly extending therefrom and terminating at said proximal end, and a filter media having an open, proximal end cooperating with said support member and a closed end extending distally away from said open end and defining the end of said filter.

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.
