Toposcopic access and delivery devices
First Claim
1. A toposcopic deployment system, comprising:
- a filling catheter;
a sleeve having a proximal end and a distal end and configured to be delivered within a body lumen, the sleeve at least partially inverted within the filling catheter, wherein the proximal end of the sleeve is removably connected to the distal end of the filling catheter;
wherein the sleeve comprises a plurality of tail elements on its distal end such that the distal end of the sleeve can be closed to promote eversion of the sleeve; and
a grasping member configured to be attached to the said tail elements of the sleeve and mechanically promote eversion of the sleeve.

Abstract
Disclosed herein are elongate flexible medical devices which are capable of axial elongation through the mechanism of eversion or toposcopic expansion. In general, this may be accomplished by providing a flexible tubular device having a proximal end and a distal end. Retraction of the distal end in a proximal direction through the tubular body inverts the tube upon itself, causing an axial shortening of the overall length of the device. The original length of the device can be restored by coupling a pressurized media to the proximal end of the sleeve. If the distal end of the sleeve is temporarily restricted or closed, the pressurized media causes the distal end of the sleeve to travel distally until the full length of the sleeve has been restored.
