1. An elongate medical device comprising:
- an elongate shaft having a shaft distal end, a shaft proximal end, and a cross-section, wherein the shaft distal end includes a pull-back sheath;
a stent covered by the shaft distal end; and
a slider captured on the shaft between the shaft distal end and the shaft proximal end and configured to line a percutaneous hole during a percutaneous medical procedure allowing the shaft to advance into and retract from the percutaneous hole, the slider having a maximum outer diameter that is substantially the same as or less than the maximum outer diameter of the shaft distal end,wherein a pull wire is disposed within the shaft attached to the pull-back sheath and is proximally operable.

Abstract
This invention relates to an elongate medical device, with a distal end to be advanced into the body of a patient and then withdrawn from the body and an elongate shaft connecting the distal end with a proximal end that remains outside the body, the shaft extending in use through a hole in the skin of the body characterized by a slider, captivated on a portion of the length of the shaft, which is capable of lining the said hole, as the shaft is advanced and withdrawn relative to said hole and the slider in the hole, said slider having a maximum outer diameter that is substantially the same as or Jess than a maximum outer diameter of the distal end.

3. An elongate medical device comprising:
-
a sheath distal end; an elongate shaft connecting a shaft distal end with a shaft proximal end, the shaft extending percutaneously in use; and a slider captured on the shaft between the shaft distal end and the shaft proximal end and configured to line a percutaneous hole during a percutaneous medical procedure allowing the shaft to advance into and retract from the percutaneous hole, the slider having a maximum outer diameter that is substantially the same as or less than the maximum outer diameter of the shaft distal end, wherein the shaft has a shaft proximal portion having a diameter that is greater than a diameter of a portion of the shaft between the shaft proximal portion and a shaft distal portion, and wherein the shaft proximal portion has a maximum outer diameter that is substantially the same as a maximum outer diameter of the sheath distal end. - View Dependent Claims (4, 5, 6)

7. An elongate medical device comprising:
-
a percutaneously adapted shaft having a distal end including a pull-back sheath adapted for internal placement and a proximal end adapted to remain outside the body wherein the proximal end comprises a single lumen connecting the shaft distal and proximal ends, a stent covered by the shaft distal end; and a slider captured on the shaft between the shaft distal end and the shaft proximal end and configured to line a percutaneous hole during a percutaneous medical procedure allowing the shaft to advance into and retract from the percutaneous hole, the slider having a maximum outer diameter that is substantially the same as or less than a maximum outer diameter of the shaft distal end, wherein the shaft portion includes a pull wire for manipulating the pull-back sheath proximally. - View Dependent Claims (8)

9. An elongate medical device comprising:
-
an elongate shaft comprising a single lumen connecting a shaft distal end with a shaft proximal end, in use the shaft extending percutaneously, a stent covered by the shaft distal end; and a slider captured on the shaft between the shaft distal end and the shaft proximal end and configured to line a percutaneous hole during a percutaneous medical procedure allowing the shaft to advance into and retract from the percutaneous hole, the slider having a maximum outer diameter that is substantially the same as or less than a maximum outer diameter of the shaft distal end, wherein the shaft has a proximal portion having a diameter that is greater than a diameter a middle portion of the shaft that is distal of the shaft proximal portion and proximal of a shaft distal portion, and the shaft proximal portion has a maximum outer diameter that is substantially the same as a maximum outer diameter of the shaft distal end. - View Dependent Claims (10, 11, 12)
