Coated medical devices and methods of making and using same |
摘要 |
Coating methods and related devices are provided. Such devices can include stents. For example, the device can comprise a sidewall and a plurality of pores in the sidewall that are sized to inhibit flow of blood through the sidewall into an aneurysm to a degree sufficient to lead to thrombosis and healing of the aneurysm when the tubular member is positioned in a blood vessel and adjacent to the aneurysm. The device can also comprise an anti-thrombogenic coating distributed over at least a portion of the device such that the pores are substantially free of webs formed by the coating. |

1. A medical device for treating an aneurysm, comprising:
a tubular member comprising a plurality of braided filaments, each of the filaments crossing another of the filaments at a respective crossing point, that form a sidewall and a plurality of pores in the sidewall that are sized to inhibit flow of blood through the sidewall into an aneurysm to a degree sufficient to lead to thrombosis and healing of the aneurysm when the tubular member is positioned in a blood vessel and adjacent to the aneurysm, the pores having an average pore size that is less than or equal to about 500 microns when the body is in the expanded state; and an antithrombogenic material distributed over the tubular member wherein the pores are substantially free of webs formed by the material such that webs are present at fewer than 5% of the crossing points. |
