rack it very carefully with your syphon. no really.
Some racking canes have this nifty widget on the botom of the cane to prevent shmenk from getting in.
One other option, is to rack it to another vessel for another 5-7 days then into a keg.
The hops that do escape to the keg wil settle out, and if in the event the hops get clogged in the line, may easliy be remedied by taking the gas input, and putting it on the output for second or two to blast the hops out of the line.
