Push and pull medical device delivery system

A delivery system for an implantable prosthesis, said delivery system comprising:

• a first elongated delivery member including a first guidewire limen;
• a constraining member;
• a second elongated delivery member separate from the first elongated delivery member, and configured to be inserted into a body of a patient separately from the first elongated delivery member;
• and
• an expandable device coupled to the first and second elongated delivery members and constrained by the constraining member, wherein a partial deployment of a portion of the expandable device within a bore of the second delivery member and toward engagement with the second delivery member while the expandable device is disposed about an exterior of the first delivery member defines a releasable coupling between the expandable device and the second delivery member, wherein the partial deployment includes releasing the constraining member from the portion of the expandable device, wherein an end of one of the first and second elongated delivery members is configured to be received within an end of the other first and second elongated delivery members.

A system for delivery of a medical device, said system comprising:

• a catheter having a mounting portion;
• and
• a medical device disposed about an exterior of the mounting portion and constrained by a constraining member,
• wherein the catheter further includes an elongated first portion having a first guidewire lumen and configured to exit a body through a first insertion site and an elongated second portion configured to exit the body through a second insertion site that is different from the first insertion site while the medical device is positioned at the treatment site, the second portion being configured to receive the medical device and the constraining member within a bore of the second portion while the medical device is disposed about the mounting portion, and
• wherein at least one of the first and second portions has substantially no column strength, wherein an end of one of the first and second portions is configured to be received within an end of the other first and second end portions.

A system for delivery of a medical device, said system comprising:

• a first elongated delivery member having a first guidewire lumen and configured to exit a body through a first insertion site;
• a second elongated delivery member configured to exit the body through a second insertion site that is different from the first insertion site, the second elongated delivery member being separate from the first elongated delivery member and configured to be inserted into a body of a patient separately from the first elongated delivery member;
• and
• a medical device mounted between the first elongated delivery member and the second elongated delivery member such that the medical device is disposed about an exterior of the first elongated delivery member and constrained by a constraining member such that the medical device, the first elongated delivery member, and the constraining member are disposed within a bore of the second elongated delivery member,
• wherein the first and second elongated delivery members extending outside the body through the respective first and second insertion sites are configured to be manipulated to position the medical device, and
• wherein at least one of the first elongated delivery member and the second elongated delivery member is sufficiently flexible in that it is not capable of being advanced through the body by pushing, wherein an end of one of the first and second elongated delivery members is configured to be received within an end of the other first and second elongated delivery members.

A delivery system for an implantable prosthesis, said delivery system comprising:

• an expandable implantable prosthesis;
• a first catheter having a first guidewire lumen, a first catheter outer wall, and a first catheter inner wall, the first catheter being configured to extend outside of a body from a first percutaneous access site;
• and
• a second catheter having a second catheter outer wall and a second catheter inner wall, the second catheter being configured to extend outside of the body from a second percutaneous access site that is different from the first percutaneous access site, the second catheter being separate from the first catheter and configured to be inserted into a body of a patient separately from the first catheter,
• wherein the first catheter inner wall extends along the second catheter outer wall such that the first and second catheters partially overlap, and
• wherein the expandable implantable prosthesis is constrained at least partially by the first catheter inner wall and constrained at least partially along the second catheter outer wall by a releasable constraining member, wherein an end of one of the first and second catheters is configured to be received within an end of the other first and second catheters.

A system for delivery of a medical device, said system comprising:

• a delivery member including an elongated first portion having a first guidewire lumen and configured to extend outside of a body from a first percutaneous access site, and an elongated second portion configured to extend outside the body from a second percutaneous access site that is different from the first percutaneous access site, the elongated second portion being separate from the elongated first portion and configured to be inserted into a body of a patient separately from the elongated first portion;
• and
• a medical device releasably coupled to the delivery member and releasably retained in a delivery configuration by a constraining member for endoluminal delivery of the medical device toward a treatment site in a human vessel,
• wherein the delivery member allows for positioning of the medical device at the treatment site by manipulation of the first portion and the second portion from outside of the body, and wherein the second portion is releasably coupleable with the first portion such that the first and second portions are coaxially aligned with the medical device, the constraining member, wherein an end of one of the first and second portions is configured to be received within an end of the other first and second end portions.
