Abstract
A method of handling an endoprosthesis includes providing an endoprosthesis having a deposited metal film with a thickness of about 50 microns or less and reducing the diameter of the endoprosthesis by sequentially collapsing different portions of the prosthesis. The collapsed endoprosthesis can be positioned with a lumen of an endoprosthesis delivery device. Different portions of the endoprosthesis can be sequentially and radially collapsed. For example, the endoprosthesis can be disposed within a hollow form of varying diameter.
Claims24
A method of handling an endoprosthesis, comprising:
- providing an endoprosthesis including a deposited metal film having a thickness of about 50 microns or less, and
- reducing the diameter of the endoprosthesis by sequentially collapsing different portions of the prosthesis.
A method of handling an endoprosthesis, comprising:
- providing an endoprosthesis including a deposited metal film having a thickness of about 50 microns or less, and
- reducing the diameter of the endoprosthesis by disposing the endoprosthesis in a polymer tube, and
- reducing the diameter of the tube.
A method of handling an endoprosthesis, comprising:
- providing a stent,
- reducing the diameter of the stent,
- providing a stent cover, the stent cover including deposited metal film having a thickness of about 50 microns or less,
- disposing the stent cover over the stent with the stent in a reduced diameter form, and
- disposing the covered stent in a collapsed condition to a delivery catheter.
A method for delivering an endoprosthesis, comprising:
- providing a stent and a stent cover, wherein at least one of the stent and stent cover includes a deposited metal film having a thickness of about 50 microns or less, and sequentially deploying the stent and stent cover in a body lumen.
The method of clam 19 wherein the stent and stent cover are loaded into a common delivery catheter.
An apparatus for handling an endoprosthesis, comprising:
- a support mandrel including a series of protrusions and an endoprosthesis including a deposited metal film having a thickness of about 50 microns or less, the protrusions supporting the film.
