Abstract
Medical devices that include a tubular member with a plurality of braided filaments, each filament crossing another of the filaments at a respective crossing point forming 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 have an average pore size that is less than or equal to about 500 microns when the tubular member is in an expanded state, the filaments possessing antithrombogenic surfaces to increase antithrombogenicity of the medical device with pores substantially free of webs formed by antithrombogenic material, such that fewer than 5% of the crossing points have webs formed by antithrombogenic material thereby permitting the pores to be substantially free of webs.
