Abstract

A medical device can include a metal member including a porous first portion with pores extending from a surface of the metal member into the first portion and non-porous second portion. The first portion can have a porosity that varies with distance from the surface of the metal member.

Claims (22)

1. A medical device, particularly an endoprothesis, comprising:
a metal member including a porous first portion with pores extending from a surface of the metal member into the first portion and non-porous second portion;
wherein the first portion has a porosity that varies with distance from the surface of the metal member, particularly wherein the porosity of first portion increases with distance from the surface.
2. The medical device of claim 1, wherein the first portion includes a surface layer of pores with a first representative pore size and an interior layer of pores with a second representative pore size that is greater than the first representative pore size, pores of the surface layer interconnected to provide a plurality of fluid flow paths extending between the surface and the interior layer.
3. The medical device of claim 2, further comprising a therapeutic agent disposed within the interior layer of pores and/or wherein the first representative pore size is between about 0.5 and 5 nanometers, particularly wherein the first representative pore size is between about 1.5 and 3 nanometers and/or wherein the second representative pore size is between about 50 nanometers and 500 nanometers.
4. The medical device of claim 2 or claim 3, further comprising a plug disposed in a bore extending between the surface and the interior layer.
5. The medical device of any of claims 1-4, wherein the metal member is a tubular member having an axis and the first portion is disposed between the second portion and the axis.
6. The medical device of any of claims 1-5, wherein the porous first portion and the non-porous second portion are integrally formed.
7. The medical device of any of claims 1-6, wherein the metal member comprises struts interconnected at junctions and the pores are not present at the junctions.
8. The medical device of any of claims 1-7, further comprising a coating, the coating covering a portion of the surface of the metal member and extending into the pores of the first portion, particularly wherein the coating comprises a polymer or wherein the coating comprises a ceramic.
9. The medical device of any of claims 1-8, wherein the medical device forms at least part of a dental implant.
10. The medical device of any of claims 1-8, wherein the first portion includes a surface layer of pores with a first representative pore size and the first representative pore size is less than about 200 nanometers.
11. The medical device of any of claims 1-8, wherein the medical device forms at least part of a bone implant.
12. The medical device of any of claims 1-8, wherein the medical device forms at least part of an embolic coil.
13. A method of forming an endoprosthesis, the method comprising:
forming a pre-endoprosthesis from a metal; and forming pores in the metal by implanting ions of a noble gas, particularly argon or helium, in the metal.
14. The method of claim 13, wherein forming the endoprosthesis takes place before forming the pores.
15. The method of claim 13, wherein forming the pores takes place before forming the endoprosthesis.
16. The method of any of claims 13-15, wherein the metal is selected from the group consisting of titanium, stainless steel, stainless steel alloy, tungsten, tantalum, niobium, and zirconium.
17. The method of any of claims 13-16, further comprising covering portions of the metal with a sacrificial material which limits ion implantation.
particularly wherein the method further comprises removing the sacrificial layer.
18. The method of any of claims 13-17, wherein implanting the ions comprises applying the ions at an implantation energy of between about 10 kiloelectronvolts and 1 megaelectronvolts.
19. The method of any of claims 13-18, wherein implanting the ions comprises applying the ions at a dose of between about 15 x 10 17 and 50 x 10 18 ions per square centimeter.
20. The method of any of claims 13-19, forming the pores comprises forming a surface layer of pores with a first representative pore size and an interior layer of pores with a second representative pore size that is greater than the first representative pore size, pores of the surface layer interconnected to provide a plurality of fluid flow paths extending between a surface of the metal and the interior layer of pores.
21. The method of claim 20, further comprises:
forming a bore extending from the surface of the metal to the interior layer of pores;
loading a therapeutic agent into the interior layer of pores; and placing a seal material in the bore.
22. The method of any of claims 13-21, further comprising applying a mask to control locations at which pores are formed in the metal.
