Implantable attaching ring
First Claim
Patent Images
1. An implantable apparatus for receiving a heart valve, comprising:
- an annular ring having an inner wall and an outer wall, the inner wall defining an axial passageway;
a plurality of channels displaced circumferentially about the ring, each channel extending from the inner wall to the outer wall; and
a plurality of tissue attachment pins each pin being movable in a respective one of the channels between a first position, wherein a first end of each pin is positioned in its respective channel adjacent the outer wall and a second end of each pin extends into the axial passageway during implantation, and a second position wherein the first end of each pin extends beyond the outer wall for tissue attachment, and the second end of each pin is moved toward the channel and out of the axial passageway.

Abstract
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.
