## Abstract

A woven tubular endoprosthesis comprising means for locking the endoprosthesis in a deployed configuration is disclosed. The means for locking the endoprosthesis may comprise locking protrusions, notches, a chemical bond, a curable bond, or other mechanism. The woven fibers comprising the endoprosthesis may be hollow and comprise circumferentially oriented polymeric chains, and may be filled with a curable material. A method of treatment using an endoprosthesis according to the invention is also disclosed.

## Claims

### Claim 1

An expandable tubular endoprosthesis comprising a length, an axis extending along said length, and one or more erodible tubular fibers, wherein said one or more fibers is oriented transversely to said axis at an angle of between 10° and 105° to form one or more points of intersection between said one or more fibers, the endoprosthesis also comprising a reduced profile delivery configuration and an expanded profile deployed configuration, said one or more fibers further comprising a plurality of locking elements proximate said one or more points of intersection wherein said locking elements are disengaged when said endoprosthesis is in the reduced profile delivery configuration and said locking elements are engaged when the endoprosthesis is in the deployed configuration and wherein a first locking element is oriented in a first direction and a second locking element is oriented in a second direction that is perpendicular to said first direction wherein during expansion, one or more of said fibers passes over at least one locking element and cannot pass in a reverse direction, thereby engaging said locking element to maintain said endoprosthesis in said deployed configuration.

### Claim 2 (depends on 1)

The endoprosthesis according to claim 1 wherein one or more of said fibers is filled with a curable material.
