Expandable delivery appliance particularly for delivering intravascular devices
First Claim
1. A delivery appliance for delivering an expandable annular device to a desired location in a lumen, comprising:
- an annular array of supporting strips extending from a proximal end of the annular array to a distal end of the annular array, to define an annular supporting surface for said expandable annular device, each of said supporting strips being laterally deformable to radially expand or radially contract said annular array and said annular supporting surface defined thereby;
and a connecting stem passing through said annular array of supporting strips;
said connecting stem having a distal end coupled to said supporting strips at the distal end of the annular array for axial movement therewith, and a proximal end passing through the proximal end of the annular array of supporting strips for axial movement with respect thereto;
said proximal end of the connecting stem being axially movable in one direction to move said distal end of the annular array axially away from said proximal end of the annular array to radially contract said annular supporting surface;
said proximal end of the connecting stem being axially movable in the opposite direction to move said distal end of the annular array axially towards said proximal end of the annular array to radially expand said annular supporting surface.

Abstract
A delivery appliance for delivering an expandable annular device, particularly an expandable intravascular device, to a desired location in a lumen, includes an annular array of supporting strips extending from a proximal end of the annular array to a distal end of the annular array, to define an annular supporting surface for the expandable annular device. Each of the supporting strips is laterally deformable to radially expand or radially contract the annular array and the annular supporting surface defined thereby. A connecting stem passes through the annular array of supporting strips and has a distal end coupled to the supporting strips at the distal end of the annular array for axial movement therewith, and a proximal end passing through the proximal end of the annular array of supporting strips for axial movement with respect thereto. The proximal end of the connecting stem is axially movable in opposite directions to move the distal end of the annular array axially away from or towards, the proximal end of the annular array to radially contract or radially expand the annular supporting surface.

15. A delivery appliance for delivering an expandable intravascular device to a desired location in a lumen, comprising:
-
an annular array of supporting strips dimensioned to receive said expandable intravascular device and extending from a proximal end of the annular array to a distal end of the annular array, to define an annular supporting surface for said expandable intravascular device, each of said supporting strips being laterally deformable to radially expand or radially contract said annular array of supporting strips, and said annular supporting surface defined thereby;
and a connecting stem passing through said annular array of supporting strips;
said connecting stem having a distal end coupled to said supporting strips at the distal end of the annular array for axial movement therewith, and a proximal end passing through the proximal end of the annular array of supporting strips for axial movement with respect thereto;
said proximal end of the connecting stem being axially movable in one direction to move said distal end of the annular array axially away from said proximal end of the annular array to radially contract said annular supporting surface, and thereby to permit the intravascular device to be received thereon, to be delivered via the lumen to a desired location therein, and to be removed from the lumen after delivering the intravascular device to said desired location therein;
said proximal end of the connecting stem being axially movable in the opposite direction to move said distal end of the annular array axially towards said proximal end of the annular array to radially expand said annular supporting surface and said intravascular device supported thereon. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)
