1. A system for implanting a prosthesis, comprising:
- a prosthesis delivery device having;
a handle having a longitudinal axis and a lumen control assembly;
an inner lumen having a distal end extending from said lumen control assembly, said inner lumen including a first lumen and a second lumen disposed about said first lumen, wherein said first and second lumens are slidably displaceable with respect to one another;
a nose cone at said distal end of said inner lumen and having a proximal end;
an intermediate lumen having a distal end and extending from said lumen control assembly, said intermediate lumen being disposed about said inner lumen;
a prosthesis sheath having a distal end and extending from said distal end of said intermediate lumen and about said inner lumen for holding therein a prosthesis to be implanted, wherein said distal end of said prosthesis sheath is releasably held under said proximal end of said nose cone;
an outer lumen fixedly connected to said handle with respect to said longitudinal axis and extending about said intermediate lumen; and
said lumen control assembly operable to move said intermediate lumen about said inner lumen with said prosthesis sheath between;
a retracted position in which, when a prosthesis is disposed within said prosthesis sheath, both said prosthesis sheath and the prosthesis are disposed within said outer lumen; and
an extended position in which, when the prosthesis is disposed within said prosthesis sheath, a portion of said prosthesis sheath containing the prosthesis is disposed outside said outer lumen wherein said lumen control assembly includes;
a first state in which said inner lumen moves dependently with said intermediate lumen along said longitudinal axis; and
a second state in which said inner lumen moves independently from said intermediate lumen along said longitudinal axis.

Abstract
A system for implanting a prosthesis includes a prosthesis delivery device having a handle, an inner lumen, a nose cone, an intermediate lumen, a prosthesis sheath at the distal end of the intermediate lumen for holding therein a prosthesis to be implanted, and an outer lumen fixedly connected to the handle. The system can include a lumen control assembly operable to move the intermediate lumen with the prosthesis sheath between a retracted position and an extended position.

9. A system for implanting a prosthesis, comprising:
-
a prosthesis delivery device having; a handle having a longitudinal axis and a lumen control assembly; an inner lumen extending from said lumen control assembly; an intermediate lumen having a distal end and disposed about said inner lumen, connected to said lumen control assembly; a prosthesis sheath extending from the distal end of said intermediate lumen for holding therein a prosthesis to be implanted, said prosthesis sheath disposed about said inner lumen; an outer lumen fixedly connected to said handle with respect to said longitudinal axis and extending about said intermediate lumen; and said lumen control assembly; operable to move said intermediate lumen with said prosthesis sheath between; a refracted position in which, when the prosthesis is disposed within said prosthesis sheath, both said prosthesis sheath and the prosthesis are disposed within said outer lumen; and an extended position in which, when the prosthesis is disposed within said prosthesis sheath, a portion of said prosthesis sheath containing the prosthesis is disposed outside said outer lumen, wherein the lumen control assembly includes a first state in which said inner lumen moves dependently with said intermediate lumen along said longitudinal axis; a second state in which said inner lumen moves independently from said intermediate lumen along said longitudinal axis; and a third state, wherein said inner lumen is fixed along said longitudinal axis when said prosthesis sheath and said intermediate lumen are moved in a proximal direction along said longitudinal axis to unsheath the prosthesis contained in said prosthesis sheath. - View Dependent Claims (10, 11, 12, 13, 14, 15)
