Abstract
A vascular dilator for controlling blood flow in a blood vessel, includes an elongate body for inserting into a blood vessel and a generally tapered distal end portion and a proximal end portion, and a plurality of inflatable members positioned adjacent the distal end portion. The inflatable members are longitudinally spaced from one another by a predetermined distance.

A dilator-introducer sheath complex for allowing repair of an aneurysm in an arterial blood vessel of a subject by first stopping the flow of blood through the arterial blood vessel, consisting of:
- a) a dilator, consisting of:
- i) an elongate generally rigid body having a length, a proximal end portion and distal end portion;
- ii) a tapered distal end portion;
- iii) a plurality of inflatable members positioned adjacent the distal end portion on the elongate generally rigid body;
- iv) the plurality of inflatable members being longitudinally spaced from one another by a distance of 2 cm to less than 5 cm and being proximal to the tapered distal end portion;
- and
- v) the elongate generally rigid body having a solid tubular structure with a generally uniform diameter throughout the length thereof, and including a plurality of peripherally oriented lumens in fluid communication with the respective plurality of inflatable members and a central channel for extending a guidewire therethrough;
