Claim:
1. A method of fastening soft tissue to a bone, the method comprising steps of: preparing a bone hole in the bone for receiving a suture anchor having a length of suture connected thereto, the suture anchor comprising a plurality of plates configured into a stack, the stack having an undeployed configuration, and a deployed configuration in which one or more of the plates is positioned outwardly more laterally with respect to the stack than in the undeployed configuration, and a biasing member between the plates in the stack biasing the one or more plates toward the deployed configuration; holding the suture anchor in the undeployed configuration via a retention member passed through the plates; positioning the suture anchor in the bone hole while the suture anchor is in the undeployed configuration; connecting the suture to the soft tissue; tensioning the suture to draw the soft tissue toward the bone; and deploying the anchor so that the biasing member moves the plates into the deployed configuration to retain the anchor in the bone hole.
