A method for securing an anchor to tissue includes positioning the anchor in an area of the tissue. The anchor can include a flexible first tubular member, a flexible second tubular member, and a first suture member. The first tubular member can include a first wall defining a first passage between first and second ends. The second tubular member can include a second wall defining a second passage between first and second ends. The first suture member can couple the first tubular member and the second tubular member. The first suture member can pass through the first wall and the first passage and the second wall and the second passage. The first tubular member and the second tubular member can engage each other and deform to form an anchoring mass upon tensioning the first suture member.
