1. An extra-anatomic heart valve apparatus comprising:
- a heart valve having an inflow end, an outflow end and a central axis extending through the inflow and outflow ends;
a substantially flexible stent element disposed substantially coaxially about said heart valve intermediate the inflow and outflow ends of said heart valve;
an elongated outflow conduit extending longitudinally from the outflow end of said heart valve and terminating in a distal end spaced from said heart valve;
at least one resilient support disposed about said outflow conduit intermediate the outflow end of said heart valve and the distal end of said outflow conduit; and
an outer sheath of biological material connected with said outflow conduit and covering said a least one resilient support.

Abstract
An extra-anatomic heart valve apparatus, which may be mounted externally to the heart, includes a heart valve positioned within a generally tubular conduit. An elongated outflow conduit extends from the tubular conduit and terminates in an end spaced from the heart valve. A resilient support and/or corrugations may be added to the outflow conduit to help resist compression of the conduit as well as to facilitate bending thereof.

16. An extra-anatomic heart valve apparatus comprising:
-
a first conduit portion having a substantially cylindrical sidewall with first and second spaced apart ends; a heart valve having inflow and outflow ends mounted within said first conduit portion between the respective first and second ends of said first conduit portion; an elongated second conduit portion extending longitudinally from the second end of said first conduit portion, said second conduit portion having a substantially cylindrical sidewall with a first end connected at the second end of said first conduit portion and terminating in a second end spaced apart from the first end of said second conduit portion; and a plurality of circumferentially extending corrugations formed in the sidewall of said second conduit portion. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23)

28. An extra-anatomic heart valve apparatus comprising:
-
a heart valve having an inflow end, an outflow end and a central axis extending through the inflow and outflow ends; a substantially flexible stent element disposed about said heart valve intermediate the inflow and outflow ends of said heart valve; a generally cylindrical sheath of biological material being mounted coaxially about said valve and said stent element, said sheath having an axial length about equal to or greater than the axial length of said heart valve, said sheath having a first end adjacent said inflow end of said heart valve and a second end adjacent said outflow end of said heart valve; an elongated, flexible outflow conduit having a sidewall connected to and extending longitudinally from the second end of said sheath and terminating in a distal end spaced from said heart valve, a plurality of circumferentially extending corrugations formed in the sidewall of said outflow conduit; a generally rigid, tubular implantation member connected to and extending from the distal end of said outflow conduit, said implantation member having an outer sidewall with an implantation flange extending outwardly from the outer sidewall of said implantation member adjacent the second end of said second conduit portion; and an elongated, flexible inflow conduit connected to and extending longitudinally from the first end of said sheath. - View Dependent Claims (29)
