Claim:
1. A medical device for treating an aneurysm, comprising: a tubular member comprising a plurality of braided filaments 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, each of the filaments crossing another of the filaments at a respective crossing point; and an antithrombogenic material distributed over the tubular member such that the pores are substantially free of webs formed by the material such that webs are present at fewer than 5% of the crossing points; wherein the tubular member exhibits an elapsed time before peak thrombin formation that is at least 1.5 times the elapsed time of an identical, uncoated tubular member.
