Abstract
An endoprosthesis for deployment within a body passage includes an external tubular framework disposed about a tubular member, e.g., a metallic film having a thickness of about 50 μm or less. The tubular member may be sandwiched between the external tubular framework and an internal tubular framework located internally of the external tubular framework and the tubular member. Whether or not the internal tubular framework is included, the endoprosthesis can be self-expanding. During deployment of the endoprosthesis using a deployment device, the external tubular framework prevents substantial frictional contact between the deployment device and the tubular member.
Claims20
An endoprosthesis for deployment within a body passage, comprising:
- a tubular framework;
- and
- a metallic film having a thickness of about 50 μm or less and disposed internally of the tubular framework.
A self-expanding endoprosthesis for deployment within a body passage, comprising:
- a first tubular framework;
- a tubular member disposed around the first tubular framework;
- and
- a second tubular framework disposed around the tubular member.
A delivery device for deploying an endoprosthesis within a body passage, comprising:
- an elongate inner member;
- a self-expanding endoprosthesis disposed about a distal portion of the inner member, the endoprosthesis comprising a tubular framework disposed about a deposited metallic film;
- and
- an outer sheath surrounding the elongate inner member and the self-expanding endoprosthesis, wherein the tubular framework prevents substantial frictional contact between the tubular member and the outer sheath.
