Abstract
A delivery catheter for a stent. The delivery catheter may comprise a distal end and a proximal end. The distal end includes a stent attachment region adapted to receive a stent. The stent may be of the self-expanding type. The catheter further comprises a handle at its proximal end and at least one sheath which may at least partially circumferentially cover said stent such as to retain it in a collapsed configuration. The sheath is coupled at its proximal end to an actuator located on said handle portion.

24. A delivery catheter for delivery of a valve stent,
comprising a distal end and a proximal end, said distal end including a stent attachment region adapted to receive a stent, preferably of the self-expanding type; -
said proximal end comprising a handle portion; and at least one sheath configured to at least partially circumferentially cover said stent such as to retain said stent in a collapsed configuration, said sheath being coupleable at its proximal end to an actuator located on said handle portion such as to be moved along said stent at least one of feedback means and braking means to indicate when the distal end of the sheath has reached a defined position on the stent during proximal and/or distal movement of said sheath along said stent and/or to cause a braking effect once the distal end of the sheath moves beyond a defined position along the stent. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42)

43. A delivery catheter for a stent comprising a distal end and a proximal end, the distal end including a stent attachment region adapted to receive a stent, the catheter further comprising a handle at its proximal end and at least one sheath configured for at least partially circumferentially covering said stent such as to retain it in a collapsed configuration, the sheath being coupled at its proximal end to an actuator located on said handle for actuating movement of the sheath, the delivery catheter further comprising a removable stop for obstructing actuator displacement beyond a certain position, the removable stop comprising first and second parts movable relative to one another and having spaced apart portions that, when squeezed one towards the other, are configured to release the stop from the handle.
