Cannulated anchor and system

A cannulated anchor as part of a system for installing at least one flexible member into tissue, the anchor comprising:

• an essentially cylindrical inner core anchor portion, having a core length, defined along a longitudinal system axis, the length extending between a leading end and a trailing end, the inner core anchor portion comprising:
• a cannulation centrally disposed along the axis, the cannulation sized to accept a guidewire therethrough along the core length, the cannulation sized to engage an installer therethrough along a trailing portion of the core length;
• at least one recess disposed circumferentially about the core anchor portion, the at least one recess sized to accept a recess portion of the at least one flexible member;
• and
• a plurality of channels, each channel disposed essentially along the axis, each channel extending from the trailing end and in communication with the at least one recess, each channel sized to accept a channel portion of the at least one flexible member;
• and
• an outer anchor portion having an outer length defined along the system axis and an outer surface;
• such that the outer surface is capable of effecting anchoring of the cannulated anchor into the tissue.
