Claim Text:
1. An endovascular occlusion system for occluding a major vessel of a patient, the endovascular occlusion system comprising: a catheter member having a proximal section and a distal section and plural lumens within the catheter member, the plural lumens passing longitudinally from the proximal section to the distal section along a longitudinal axis, the catheter member having a main diameter; an occlusion balloon connected to the catheter member and being in fluid communication with a first lumen of the plural lumens within the catheter member; a curved distal tip at a leading end of the distal section, the occlusion balloon positioned proximally along the catheter member relative to the curved distal tip, the curved distal tip having a distal tip shaft between the occlusion balloon and a curved portion of the curved distal tip, a tip diameter measured on the longitudinal axis through the distal tip shaft, the curved portion of the curved distal tip being configured to prevent departure from a vessel path as the curved distal tip and the catheter member are advanced together from an insertion puncture in the patient to a predetermined location in the major vessel, the curved portion of the curved distal tip including a maximum spaced portion spaced at a lateral distance radially from the longitudinal axis, the lateral distance being greater than the tip diameter, the curved portion of the distal tip being sufficiently flexible to straighten from a curved configuration; a distal pressure sensor port positioned on the catheter member between the occlusion balloon and the distal tip, the distal pressure sensor port being in communication with a pressure lumen of the plural lumens; a hypotube extending substantially parallel to the longitudinal axis within the catheter member, the hypotube including a lumen therein; and a multi-port and valve assembly in fluid communication with a proximal end of a pressure sensor lumen of the plural lumens within the catheter member.
