1. A catheter adapted for use in the vasculature of a patient, comprising:
- an elongate body having a distal section and a proximal section, said body having a substantially continuous cross-sectional profile of not greater than about 0.135 inches; and
an occlusive device mounted on the distal section of said body, said occlusive device comprising an occlusion balloon coupled thereto and having an activated state for embolic containment and a deactivated state having a lower cross-sectional profile not substantially greater than said cross-sectional profile of said body;
said body comprising;
an inner structure defining a main lumen for slidably accommodating other vascular catheters and the like, said main lumen having a diameter of about 0.05 inches to about 0.12 inches and having a side wall, said side wall characterized by an absence of perforations therethrough;
stiffener material arranged over said inner structure;
an outer peripheral structure surrounding said inner structure and said stiffener material; and
an elongate hollow structure defining a secondary lumen for passing inflation media to said occlusive balloon to activate said balloon, said elongate hollow structure inserted within said outer perimeter structure and over said stiffener material so as to be in side-by-side arrangement with said inner structure to provide additional stiffening thereto, all of said structures being bonded together to form said body, said secondary lumen having a major axis and a minor axis;
said secondary lumen having a proximal section and a distal section, said proximal section having a substantially tubular cross-sectional profile of about 0.008 inches to about 0.018 inches and said distal section having a lower non-circular, substantially oval cross-sectional profile in the vicinity of and proximal to said occlusive device, wherein a ratio of the secondary lumen major axis to the secondary lumen minor axis in the distal section of said catheter is greater than a ratio of the secondary lumen major axis to the secondary lumen minor axis in the proximal section of said catheter, and whereby said catheter has a substantially continuous cross-sectional profile.

Abstract
Disclosed herein is a catheter for use in an emboli containment system. In one embodiment, the catheter has a tubular body with a metallic braid construction. Two lumen extend through the tubular body, the lumen being in a side-by-side configuration. One of the lumen functions as an inflation lumen, and is in fluid communication with an inflatable balloon mounted on the distal end of the catheter. The second lumen is adapted to receive other therapeutic catheters which comprise the emboli containment system.
