Abstract
An attachment member for securing a graft material to a vessel includes a conduit portion for attachment to the graft material. The attachment member has first and second anchor wings formed on opposite sides of an end of the conduit portion. The anchor wings are biased to extend substantially perpendicular to an axis of the conduit portion. The first and second anchor wings have arcuate shapes around substantially collinear axes for the anchor wings to define a flow path within a vessel on opposite sides of the conduit portion.
Claims7
An apparatus for securing a graft material to a vessel, said apparatus comprising:
- a conduit portion for attachment to said graft material, said conduit portion having first and second ends;
- first and second anchor wings formed on opposite sides of the first end of said conduit portion with said anchor wings biased to extend substantially perpendicular to an axis of said conduit portion;
- said first and second anchor wings having arcuate shapes around a substantially collinear axis for said anchor wings to define a flow path within a vessel on opposite sides of said conduit portion;
- wherein said second end of the conduit portion is sized to extend through a myocardium of a heart.
An implant for defining a blood flow path from a heart chamber to a coronary vessel, said implant comprising:
- a conduit having first and second ends;
- said conduit sized to extend through a heart myocardium to place said first end in fluid communication with a heart chamber;
- said second end of said conduit adapted for connection to a coronary vessel, said second end including at least two anchor wings moveable between a flared position and a collapsed position, wherein said anchor wings are biased toward the flared position.
