Stent Graft Delivery System Handle

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 connected to said lumen control assembly;
• an intermediate lumen disposed about said inner lumen, connected to said lumen control assembly, and having a distal end;
• a prosthesis sheath at said 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 about said intermediate lumen;
• and
• said lumen control assembly:
• operable to selectively move said intermediate lumen with said prosthesis sheath between:
• a retracted 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;
• having a first state in which said inner lumen moves dependently with said intermediate lumen along said longitudinal axis;
• and
• having a second state in which said inner lumen moves independently from said intermediate lumen along said longitudinal axis.

A prosthesis implantation system, comprising:

• a prosthesis;
• and
• a prosthesis delivery device having:
• a handle having a longitudinal axis and a lumen control assembly;
• an inner lumen connected to said lumen control assembly and having a distal end and a guidewire tip at said distal end;
• an intermediate lumen disposed about said inner lumen, connected to said lumen control assembly, and having a distal end;
• a relatively flexible prosthesis sheath at said distal end of said intermediate lumen for holding therein said prosthesis to be implanted, said prosthesis sheath disposed about said inner lumen;
• a relatively stiff outer lumen fixedly connected to said handle with respect to said longitudinal axis about said intermediate lumen and having a length no greater than 65 cm;
• and
• said lumen control assembly:
• operable to selectively move said intermediate lumen with said prosthesis sheath between:
• a retracted position in which, when said prosthesis is disposed within said prosthesis sheath, both said prosthesis sheath and said prosthesis are disposed within said outer lumen;
• and
• an extended position in which, when said prosthesis is disposed within said prosthesis sheath, a portion of said prosthesis sheath containing said prosthesis is disposed outside said outer lumen;
• having a first state in which said inner lumen moves dependently with said intermediate lumen along said longitudinal axis;
• and
• having a second state in which said inner lumen moves independently from said intermediate lumen along said longitudinal axis.
