A delivery system for delivering and deploying a prosthesis comprising a stent or stent graft within a natural or diseased aorta by aligning the prosthesis with a curve of the aorta, comprising: a) a guidewire lumen having a distal end and defining an interior extending along a longitudinal axis of the guidewire lumen; b) an apex release lumen having a distal end and being slidably disposed about the guidewire lumen; and c) an apex capture device, comprising i) a distal apex head fixedly connected to the distal end of the guidewire lumen, the distal apex head having a distal portion, and spokes that each include an outer circumferential surface, a distal surface facing in a distal direction that is disposed in a plane perpendicular to the longitudinal axis and defining a stopping surface portion, and a proximal surface that is tapered, whereby the proximal surface extends along a line that intersects with the guidewire lumen proximal to the distal surface of spokes at an oblique angle, and ii) a proximal apex body fixedly connected to the distal end of the apex release lumen and having fingers extending toward the distal apex head in a distal direction, the fingers defining an interior cavity shaped to receive the spokes therein, the proximal apex body and the distal apex head together defining an opening to hold proximal apices of stents therebetween, and wherein an outer circumference of the spokes of the distal head and the fingers, when the fingers overlay the spokes, define a radial space that has a thickness less than a diameter of the proximal apices of the stents, thereby defining a stent captured state of the stents in which the spokes and proximal apices of stents are received in the interior cavity to thereby constrain the proximal apices of the stents of the prosthesis, while the struts of the stents of the prosthesis spread out radially from between the fingers of the proximal apex body, and the distal apex head closes off the interior cavity along the longitudinal axis of the guidewire lumen. a) a guidewire lumen having a distal end and defining an interior extending along a longitudinal axis of the guidewire lumen; b) an apex release lumen having a distal end and being slidably disposed about the guidewire lumen; and c) an apex capture device, comprising i) a distal apex head fixedly connected to the distal end of the guidewire lumen, the distal apex head having a distal portion, and spokes that each include an outer circumferential surface, a distal surface facing in a distal direction that is disposed in a plane perpendicular to the longitudinal axis and defining a stopping surface portion, and a proximal surface that is tapered, whereby the proximal surface extends along a line that intersects with the guidewire lumen proximal to the distal surface of spokes at an oblique angle, and ii) a proximal apex body fixedly connected to the distal end of the apex release lumen and having fingers extending toward the distal apex head in a distal direction, the fingers defining an interior cavity shaped to receive the spokes therein, the proximal apex body and the distal apex head together defining an opening to hold proximal apices of stents therebetween, and wherein an outer circumference of the spokes of the distal head and the fingers, when the fingers overlay the spokes, define a radial space that has a thickness less than a diameter of the proximal apices of the stents, thereby defining a stent captured state of the stents in which the spokes and proximal apices of stents are received in the interior cavity to thereby constrain the proximal apices of the stents of the prosthesis, while the struts of the stents of the prosthesis spread out radially from between the fingers of the proximal apex body, and the distal apex head closes off the interior cavity along the longitudinal axis of the guidewire lumen. i) a distal apex head fixedly connected to the distal end of the guidewire lumen, the distal apex head having a distal portion, and spokes that each include an outer circumferential surface, a distal surface facing in a distal direction that is disposed in a plane perpendicular to the longitudinal axis and defining a stopping surface portion, and a proximal surface that is tapered, whereby the proximal surface extends along a line that intersects with the guidewire lumen proximal to the distal surface of spokes at an oblique angle, and ii) a proximal apex body fixedly connected to the distal end of the apex release lumen and having fingers extending toward the distal apex head in a distal direction, the fingers defining an interior cavity shaped to receive the spokes therein,
