Methods of manufacture and use of endoluminal devices

摘要

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.

主权项

1. An embolic protection filter, comprising:
a unibody and seamless frame that includes a support member and a plurality of struts that extend in a generally proximal direction from the support member to a connecting member that is coupled to a guide wire; a filter media that includes a base portion and a closed tapered portion, the base portion defining an open proximal end of the filter media and extending in a generally distal direction from the support member, wherein the closed tapered portion of the filter media is inverted toward the open proximal end of the filter media, and wherein an end region of the closed tapered portion of the filter media is located proximal of the open proximal end of the filter media.
