Method of making interventional medical device system having a slotted section and radiopaque marker

A method for manufacturing an interventional medical device system operable while within a body vessel, comprising:

• providing an elongated introducer having a lumen, the introducer being for administration within a body vessel;
• positioning a pusher component within the lumen of the elongated introducer, the pusher component including a generally hollow tubular portion;
• forming at least one slot in the tubular portion;
• providing a pre-assembly radiopaque marker;
• fixedly securing by clamping down and radially compresing the pre-assembly radiopaque marker having an outer surface to at least a portion of the slotted section such that the radiopaque marker is in a connected condition, including partially collapsing the slotted section;
• and
• thereby providing a connected condition at which the outer surface of the radiopaque marker on the partially collapsed slotted section of the pusher component is substantially flush with an outer surface of the tubular portion immediately proximal of the radiopaque marker, immediately distal of the radiopaque marker, or both immediately proximal and immediately distal of the radiopaque marker.

A method for manufacturing an interventional medical device system operable while within a body vessel, comprising:

• providing an elongated introducer having a lumen, the introducer being for administration within a body vessel;
• positioning a pusher component within the lumen of the elongated introducer, the pusher component having a longitudinal axis and including a generally hollow tubular portion;
• forming a plurality of longitudinal slots in the tubular position each having a length greater than a width thereof, the length being substantially parallel to the pusher component longitudinal axis;
• providing a pre-assembly radiopaque marker;
• fixedly securing by clamping down and radially compressing the pre-assembly radiopaque marker having an outer surface and an inner surface, said fixedly securing including overlaying and fixedly securing to at least a portion of the outer surface of the slotted section, such that the radiopaque marker is in a connected condition at which the marker inner surface engages the slotted section outer surface thereby clamping the marker down on and radially compressing same and thus partially collapsing the slotted section;
• and
• thereby providing a connected condition at which the outer surface of the radiopaque marker is on the partially collapsed slotted section outer surface and dimensionally reduced from a pre-assembly, radiopaque marker member that is dimensionally larger than the marker outer surface as thus assembled onto the slotted section outer surface, and the marker at its connected condition is substantially flush with an outer surface of the tubular portion immediately proximal of the radiopaque marker, immediately distal of the radiopaque marker, or both immediately proximal and immediately distal of the radiopaque marker.
