Abstract

Improved endoprostheses comprising a delivery configuration and a deployed configuration and methods of manufacture are disclosed. Some embodiments according to the invention comprise woven tubular structures and means for maintaining said structures in their expanded configurations. In one embodiment of the invention, locking elements (12, 14) disposed on one or more fibers (15, 17) maintain said endoprosthesis in its deployed configuration. In alternative embodiments, one or more axial members may maintain said endoprosthesis in its deployed configuration. In yet additional alternative embodiments, a chemical bond or thermocouple may maintain said endoprosthesis in its deployed configuration. Some embodiments according to the invention may comprise erodible material.

Claims (10)

1. An endoprosthesis comprising one or more fibers having a plurality of locking elements protruding from or notched into said fibers and oriented in at least two opposing directions, said fibers configured to define a braid and a generally tubular structure having a delivery configuration and a deployed configuration, wherein when said endoprosthesis is in said delivery configuration, said locking elements are uncoupled, and when said endoprosthesis is in said deployed configuration, said locking elements are coupled, thereby maintaining said endoprosthesis in said deployed configuration.
2. The endoprosthesis according to claim 1 wherein said endoprosthesis comprises one or more erodible materials.
3. The endoprosthesis of claim 1 wherein said one or more fibers comprise a plurality of points of intersection disposed about the circumference of the endoprosthesis when the endoprosthesis is in said deployed configuration, and wherein a plurality of said locking elements engage one or more of said fibers at one or more of said points of intersection.
4. The endoprosthesis of claim 3 wherein said one or more locking elements comprise locking protrusions.
5. The endoprosthesis of claim 3 wherein said one or more locking elements comprise one or more notches.
6. The endoprosthesis of claim 3 wherein said one or more locking elements comprise male and female elements.
7. An endoprosthesis comprising one or more fibers configured to define a braid and a generally tubular structure having a delivery configuration and a deployed configuration, wherein said fibers comprise one or more points of intersection and comprise a chemical bond at said one or more points of intersection when said endoprosthesis is in said deployed configuration, thereby maintaining said endoprosthesis in said deployed configuration, and said fibers are not bonded at said one or more points of intersection when said endoprosthesis is in said delivery configuration.
8. An endoprosthesis comprising one or more fibers having a plurality of locking elements comprising one or more thermocouples, said fibers configured to define a braid and a generally tubular structure having a delivery configuration and a deployed configuration, wherein when said endoprosthesis is in said delivery configuration, said locking elements are uncoupled, and when said endoprosthesis is in said deployed configuration, said locking elements are coupled, thereby maintaining said endoprosthesis in said deployed configuration.
9. The endoprosthesis of claim 1 wherein said endoprosthesis comprises a therapeutic agent incorporated into or upon said endoprosthesis utilizing a solvent in a supercritical state.
10. The endoprosthesis of claim 1 wherein said fibers comprise one or more curable materials.
