Patent ID: 7731654

Claim:
A delivery device for positioning and deploying an implantable device within a lumen comprising: a longitudinal outer tube having proximal and distal ends, wherein the distal end of the outer tube comprises an opening and the implantable device is positioned proximate to the distal end of the outer tube, wherein the implantable device includes a distal end and a proximal end; a longitudinal inner tube positioned within the outer tube and having proximal and distal ends, wherein the outer tube and the inner tube are axially displaceable with respect to one another, and wherein an outer diameter of the distal end of the inner tube is less than an inner diameter of the opening at the distal end of the outer tube; a side opening defined in each of the inner and outer tubes, wherein each side opening is defined proximate to the implantable device and is capable of substantially aligning with the other side opening; and a mechanism coupled to at least one of the inner and outer tubes and operable to axially displace the inner and outer tubes with respect to one another and to deploy the implantable device out of the opening at the distal end of the outer tube and within the lumen, wherein both the inner tube and the outer tube comprise a coil formed longitudinally therein, the coil including proximal and distal ends, positioned within each of the inner and outer tubes having proximal and distal ends, wherein a respective side opening of each of the inner and outer tubes is defined distally of the distal end of each of the respective coils, wherein each of the side openings aligns with each other proximate to the proximal end of the implantable device, and wherein the distal end of the outer tube extends distally of the distal end of the inner tube and proximate to the distal end of the implantable device when the side openings are aligned with one another.
