Prosthesis delivery device

A prosthesis delivery system comprising a delivery device having:

• an introduction end configured to be introduced into a lumen of a patient during use,
• an operator end configured to remain outside of a patient during use,
• a rotatable inner cannula having a cannula lumen, the rotatable inner cannula extending from the operator end to the introduction end,
• a positioner disposed at least partially over the inner cannula,
• a prosthesis retention section,
• a prosthesis retained on the prosthesis retention section, the prosthesis having a first end disposed toward the introduction end and a second end disposed toward the operator end,
• a retractable sheath slidably disposed at least partially over the prosthesis, the positioner, and the inner cannula,
• a first end attachment and release mechanism comprising a coil disposed on the inner cannula and rotatably engaged to the first end of the prosthesis,
• a second end attachment and release mechanism comprising a capture wire disposed on the positioner and releasably engaged to the second end of the prosthesis,
• wherein rotation of the inner cannula relative to the positioner releases the first end of the prosthesis from the first end attachment and release mechanism and from the delivery device, and retraction of the sheath from over the second end attachment and release mechanism automatically releases the second end of the prosthesis from the second end attachment and release mechanism and from the delivery device,
• wherein the capture wire has first end attached to the positioner, a free region, a free end, a capture position, and a release position, and
• wherein the positioner comprises a recess in an outer surface of the positioner configured to receive the free end of the capture wire in the capture position.

A prosthesis delivery system comprising a delivery device having:

• an introduction end configured to be introduced into a lumen of a patient during use,
• an operator end configured to remain outside of a patient during use,
• a rotatable inner cannula having a cannula lumen, the rotatable inner cannula extending from the operator end to the introduction end,
• a positioner disposed at least partially over the inner cannula,
• a prosthesis retention section,
• a prosthesis retained on the prosthesis retention section, the prosthesis having a first end disposed toward the introduction end and a second end disposed toward the operator end,
• a retractable sheath slidably disposed at least partially over the prosthesis, the positioner, and the inner cannula,
• a first end attachment and release mechanism comprising a coil disposed on the inner cannula and rotatably engaged to the first end of the prosthesis,
• a second end attachment and release mechanism comprising a capture wire disposed on the positioner and releasably engaged to the second end of the prosthesis,
• wherein rotation of the inner cannula relative to the positioner releases the first end of the prosthesis from the first end attachment and release mechanism and from the delivery device, and retraction of the sheath from over the second end attachment and release mechanism automatically releases the second end of the prosthesis from the second end attachment and release mechanism and from the delivery device,
• wherein the capture wire has a first end attached to the positioner, a free end, a capture position, and a release position and when in the capture position, the capture wire is disposed at least partially over the positioner and in the release position the capture wire is disposed away from the positioner and toward the first end of the delivery device.

A prosthesis delivery system comprising a delivery device having:

• an introduction end configured to be introduced into a lumen of a patient during use,
• an operator end configured to remain outside of a patient during use,
• a positioner,
• a rotatable inner cannula having a cannula lumen, the rotatable inner cannula extending from the operator end to the introduction end, wherein the positioner is disposed at least partially over the rotatable inner cannula and the rotatable inner cannula is axially slideable and rotatable relative to the positioner,
• a prosthesis retention section,
• a prosthesis retained on the prosthesis retention section, the prosthesis having a first end disposed toward the introduction end and a second end disposed toward the operator end,
• a retractable sheath slidably disposed at least partially over the prosthesis, the positioner, and the inner cannula,
• a first end attachment and release mechanism disposed on the inner cannula and rotatably engaged to the first end of the prosthesis,
• a second end attachment and release mechanism different from and independently operable from the first end attachment and release mechanism, disposed on the positioner and releasably engaged to the second end of the prosthesis,
• wherein rotation of the inner cannula relative to the positioner rotates the first end attachment and release mechanism to release the first end of the prosthesis from the first end attachment and release mechanism and from the delivery device, and
• wherein movement of the positioner relative to sheath exposes the second attachment and release mechanism and automatically releases the second end of the prosthesis from the second end attachment and release mechanism and from the delivery device.
