A device to release from an implant bed in the device a self-expanding implant by pulling back proximally, the length of the implant, a rolling membrane with an inner sleeve that extends distally to the distal end of the implant and an outer sleeve that extends proximally, from the distal end of the inner sleeve, the outer sleeve, during said release, pulling the distal end of the inner sleeve back proximally over the abluminal surface of the remainder of the inner sleeve, proximal of its distal end, the device having a slitter, that is caused to move proximally contemporaneously with the outer sleeve, to slit the inner sleeve progressively, starting at a distal point in the inner sleeve, and progressing proximally along the length of the inner sleeve. |

1. An implant delivery device, comprising:
an inner tubular member; a rolling membrane with
an inner sleeve connected to the inner tubular member wherein the inner sleeve connects proximally of a proximal end and extends distally of a distal end of an implant positioned over an implant bed,andan outer sleeve that extends proximal of a proximal end of the inner sleeve; and a slitter comprising a wire that runs an entire length of the implant bed, then passes radially outwardly through a hole in the inner sleeve and runs back proximally between the inner sleeve and the outer sleeve to a point proximal of the implant bed, the slitter configured to move proximally when the outer sleeve portion moves proximally, the slitter slitting the inner sleeve beginning at a distal point of the inner sleeve and progressing proximally along a length of the inner sleeve, wherein the slitter is a wire that runs an entire length of the implant bed, then passes radially outwardly through a hole in the inner sleeve and runs back proximally between the inner sleeve and the outer sleeve to a point proximal of the implant bed. |
