Interventional medical device system having a slotted section and radiopaque marker and method of making the same

摘要

An interventional medical device system (10) operable while within a body vessel. The system (10) comprises an elongated introducer (16) having a lumen, said introducer being adapted for administration within a body vessel; a pusher component (12) positioned within said lumen of the elongated introducer (16), said pusher component (12) including a generally hollow tubular portion and a slotted section (22) having at least one slot (24); and an arcuate radiopaque marker (30) having an outer surface, said radiopaque marker overlaying at least a portion of said slotted section (22). Said outer surface of the radiopaque marker (30) as thus assembled onto the pusher component (12) is substantially flush with an outer surface of the tubular portion immediately proximal of the radiopaque marker (30), immediately distal of the radiopaque marker (30), or both immediately proximal and immediately distal of the radiopaque marker (30). A method of manufacturing such a system is also disclosed.
