Stent with selectively covered region

A stent comprising:

• a radially expandable tubular framework having a proximal end, a distal end, and a lumen extending therethrough;
• and
• a covering surrounding the tubular framework, the covering being affixed to the tubular framework at a first affixment location;
• the covering including a proximal region extending proximal of the first affixment location and surrounding a medial region of the tubular framework;
• the covering including a skirt extending distal of the first affixment location and surrounding a distal end region of the tubular framework;
• wherein the skirt is selectively removable from the distal end region of the tubular framework to expose the distal end region of the tubular framework;
• wherein the skirt is convertible from a first configuration in which the skirt surrounds the distal end region of the tubular framework and a second configuration in which the skirt surrounds the proximal region of the covering proximal of the first affixment location.

A stent comprising:

• a radially expandable tubular framework having a proximal end, a distal end, and a lumen extending therethrough;
• a covering surrounding the tubular framework, the covering being affixed to the tubular framework at a first affixment location;
• the covering including a proximal region extending proximal of the first affixment location and surrounding a medial region of the tubular framework;
• the covering including a skirt extending distal of the first affixment location and surrounding a distal end region of the tubular framework;
• wherein the skirt is selectively removable from the distal end region of the tubular framework to expose the distal end region of the tubular framework;
• and
• a preferential tear line configured to selectively separate the skirt from the proximal region of the covering, the preferential tear line extending circumferentially around the covering distal of the first affixment location.

A stent comprising:

• a radially expandable tubular framework having a proximal end, a distal end, and a lumen extending therethrough, the tubular framework including a proximal end region extending to the proximal end of the tubular framework, a distal end region extending to the distal end of the tubular framework, and a cylindrical medial region extending between the proximal end region and the distal end region;
• a covering surrounding the tubular framework, the covering being affixed to the tubular framework at a first affixment location and at a second affixment location, the first affixment location positioned proximate a junction between the distal end region and the medial region of the tubular framework, and the second affixment location positioned proximate a junction between the proximal end region and the medial region of the tubular framework;
• the covering including a proximal region located proximal of the first affixment location and surrounding the medial region of the tubular framework;
• the covering including a skirt located distal of the first affixment location and surrounding the distal end region of the tubular framework;
• wherein the skirt is selectively removable from the distal end region of the tubular framework to expose the distal end region of the tubular framework;
• and
• a drawstring attached to the skirt, wherein the drawstring extends along the tubular framework to the proximal end of the tubular framework, wherein manipulation of the drawstring removes the skirt from the distal end region of the tubular framework.

A stent delivery system comprising:

• an elongate shaft having a handle at a proximal end thereof;
• a radially expandable stent disposed on a distal region of the elongate shaft;
• the stent including:
• a radially expandable tubular framework having a proximal end, a distal end, and a lumen extending therethrough;
• and
• a covering surrounding the tubular framework, the covering being affixed to the tubular framework at a first affixment location;
• the covering including a proximal region extending proximal of the first affixment location and surrounding a medial region of the tubular framework;
• the covering including a skirt extending distal of the first affixment location and surrounding a distal end region of the tubular framework;
• wherein the skirt is selectively removable from the distal end region of the tubular framework to expose the distal end region of the tubular framework;
• a drawstring extending from the skirt to the handle, wherein manipulation of the drawstring removes the skirt from the distal end region of the tubular framework.
