1. A delivery catheter handle assembly comprising:
- a proximal handle attached to a proximal end of an axially elongated inner member;
an intermediate handle attached to a proximal end of an axially elongated intermediate member, at least one of said proximal and said intermediate handles being designed to accommodate and engage the other of said proximal and said intermediate handles; and
a distal handle attached to a proximal end of an axially elongated external member overlying at least a portion of said intermediate member.

Abstract
A catheter handle assembly for delivering stent includes a proximal handle attached to an axially elongated inner member with a distal tip and an intermediate handle attached to an axially elongated intermediate tube with a stent basket at its end. The intermediate tube overlies at least a portion of the inner member. A distal handle is attached to an axially elongated external member overlying at least a portion of the intermediate tube are disclosed.

17. An apparatus for loading and delivering a prosthesis, the apparatus comprising:
-
a prosthesis; a core segment including a proximal handle, an axially extended inner member formed integral with said proximal handle; a middle segment including an intermediate handle, an axially elongated intermediate member formed integral with said intermediate handle, wherein one of said proximal and said intermediate handles are designed to assume and engage other of said proximal and said intermediate handles; and an external segment including a distal handle, an axially elongated external member formed integral with said distal handle and overlying at least a portion of said intermediate member. - View Dependent Claims (18)

19. A method for loading prosthesis onto a delivery system, the method comprising:
-
providing a prosthesis delivery system including a proximal handle attached to an inner member, an intermediate handle attached to an intermediate member, one of said proximal and said intermediate handles being designed to accommodate and engage another of said proximal and said intermediate handles, and a distal handle attached to an external member overlying at least a portion of said intermediate member, said proximal handle having a releasable locking mechanism for releasably engaging said intermediate handle; providing a prosthesis in a unconstrained condition; positioning said intermediate handle in a position away from said proximal handle and loading said prosthesis; moving said distal handle distally to constrain said prosthesis within said external member; and retracting said prosthesis basket into said axially elongated intermediate member by sliding said intermediate handle in a proximal direction until it locks into said proximal handle via said releasable locking mechanism and said basket is no longer in contact with said prosthesis. - View Dependent Claims (20, 21)
