An implantable attaching device includes an annular ring having an axial passageway and a plurality of channels extending radially through the ring. Tissue attaching pins are positioned in the channels and extend radially inward into the axial passageway during implantation. The pins are driven into the native annulus tissue after the ring is positioned. Once the pins are driven into the annulus, the axial passageway of the ring is unobstructed and is adapted to receive a heart valve or other implantable device.
