Claim:
A multi-luminal delivery system comprising: an outer catheter comprising a distal end and a wall that encloses an outer lumen; an inner catheter movably disposed within the outer lumen and having an inner lumen, the inner catheter having a distal end disposed proximally of the distal end of the outer catheter; a balloon-tipped catheter movably disposed within the inner lumen of the inner catheter and having a distal end and a proximal end, wherein the distal end of the balloon-tipped catheter comprises an expandable balloon tip that is disposed distally of the distal end of the inner catheter, the balloon tip being expanded into contact with the wall of the outer catheter near the distal end of the outer catheter so as to provide a seal to prevent bodily fluids from entering the outer lumen of the outer catheter; and a deployable device disposed within the outer lumen proximally of the expanded balloon tip.
