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