Abstract
Ultra-fine fibers, having an average diameter typically in the range of 0.1 to 5 micrometers, are provided which are capable of being dispersed in a liquid medium, such as a freeze dry liquid, to form a free-flowing, non-agglomerating slurry which may be employed to coat a substrate, as to provide an intimal lining for a circulatory assist device. Such ultra-fine fibers are prepared by immobilizing longer fibers in a medium, such as ice, and thereafter shearing the medium with the longer fibers embedded therein at a rate and for a time sufficient to comminute the fibers into appropriately short lengths.
