A catheter assembly ( 10 ) includes a catheter ( 20 ) having a proximal end and a distal end； an expandable device ( 30 ) releasably attached to the catheter near the distal end； a generally tubular constraining sleeve ( 40 ) extending around and compressing the device to an outer peripheral dimension suitable for endoluminal delivery； a tip ( 50 ) fixedly secured to the distal end of the catheter； and a bridge member ( 60 ) disposed between the tip and the expandable device so as to fill a gap (G) therebetween as the catheter assembly is bent during endoluminal delivery of the expandable device to a treatment site.
