Implant deployment catheter

摘要

A rapid exchange implant deployment catheter includes a relatively stiff hypotube (12) and a relatively flexible distal tube (14). A side port (15) for a guide wire is provided towards the distal end of a transition zone (16) between the hypotube (12) and the distal tube (14). The distal end of the hypotube (12) is laser cut to form a plurality of slits (18) between which are formed a plurality of projections (11, 11'). At least one of the projections (11') extends into the distal tube 14 to a point beyond the position of the side port (15).
