1. A prosthesis delivery device comprising:
- at least one sheath removably covering a prosthesis therein, said at least one sheath comprising a distal end, a proximal end, an outer surface and a channel extending between said distal end and said proximal end, said channel defining an inner wall;
said prosthesis extending in a compressed state within said channel;
an inner tubular member slidably extending through said prosthesis, said inner tubular member comprising an elongated inner shaft with a distal tip at one end; and
at least two cameras engaged to said delivery device.

Abstract
Various methods and devices are described for imaging a body lumen during delivery and deployment of a medical device. In one example, a delivery device includes at least one sheath, a prosthesis, an inner tubular member and at least two cameras to allow visualization of the prosthesis prior, during and after deployment without the use of an endoscope. The at least one sheath and/or the inner tubular member includes at least two cameras engaged to the delivery device.

16. A method for intraluminally positioning a prosthesis comprising:
-
providing a delivery device comprising at least one sheath removably covering a prosthesis therein, said at least one sheath includes a distal end, a proximal end, an outer surface and a longitudinal channel extending between said distal end and said proximal end, said channel defining an inner wall, said prosthesis extending in a compressed state within said longitudinal channel, an inner tubular member slidably extending through said prosthesis, said inner tubular member comprises an elongated inner shaft with a distal tip at one end, and at least two cameras engaged to said delivery device; activating said at least two cameras to provide images during positioning of said prosthesis; positioning said delivery device within a body lumen; and slidably retracting said at least one sheath relative to the inner tubular member to uncover said prosthesis and allow said prosthesis to radially expand against a wall of body lumen. - View Dependent Claims (17, 18, 19, 20)
