US 2003/0216801 A1 · Transmyocardial implant with natural vessel graft and method

Abstract

A transmyocardial implant includes a hollow rigid conduit having a vessel portion and a myocardial portion. The vessel portion is sized to be inserted into a blood vessel segment taken from a non-coronary artery or vein. The myocardial portion is sized to extend from the vessel portion and through a myocardium into a heart chamber. The conduit has open vessel and myocardial ends on respective ends of the vessel and myocardial portions to define a blood flow pathway within an interior of the conduit between the vessel and myocardial ends. The myocardial portion is formed of a conduit material sufficiently rigid to resist deformation and closure of the pathway in response to contraction of the myocardium. The vessel portion has a radial compliance approximating a radial compliance of the vessel.

Claims21

Dependent claims

A method revascularizing a coronary vessel of a patient comprising:

inserting a hollow conduit through a heart wall so that a first end of the conduit extends into a heart chamber and a second end of the conduit extends beyond the heart wall;
connecting the second end of the conduit with a first end of a natural vessel graft wherein the first end of the natural vessel graft is outside the heart wall;
and
attaching a second end of the natural vessel graft to the coronary artery.
