Patent ID: 8795320

Claim:
An assembly for deploying an implant into an aneurysm in a vessel, comprising: a tubular member having a longitudinal axis, a wall defining a lumen along the axis, the lumen having a lumen inner cross-sectional dimension, and a distal portion having a distal portion inner cross-sectional dimension smaller than the lumen inner cross-sectional dimension, and a distal end; a coil implant having an enlarged proximal end; and a core wire extending within the lumen and contacting the enlarged end at a point; wherein a length of a line segment extending from an outer surface of the enlarged end, through the point, and to an outer surface of the core wire is greater than the distal portion inner cross-sectional dimension, such that the enlarged end is prevented from moving within the lumen distally entirely past the distal end when the core wire and enlarged end are positioned radially adjacent each other within the lumen; wherein at least a portion of a control member extends proximally from the core wire is attached to a proximal portion of the wall at a distal portion thereof tubular member by a connector, such that while the core wire control member and tubular member are attached, relative axial movement between the core wire and the tubular member is substantially prevented; and wherein, prior to release of the coil implant from the tubular member and when the enlarged end is unable to move within the lumen distally past the tubular member distal portion, the core wire extends through distally and radially inward from a side of the lumen, contacted by the outer surface of the core wire, and into the distal portion and beyond a distal most portion of the distal end.
