Abstract:
A device for occluding a patient's blood vessel through direct access of the blood vessel, said device comprising:a flexible balloon member having an outer peripheral contact portion for coming in contact with an inner wall of the blood vessel during occlusion, said balloon member being formed of a limited compliance material which limits the expansion of the balloon member to between 1% and 40% radially and between 1% and 50% longitudinally after the balloon member is initially inflated under ambient pressure to its normal, unstretched shape, said balloon member having a diameter, said outer peripheral contact portion being substantially narrower in width than the diameter of the balloon member;a tubular member, said balloon member being attached to the tubular member near a distal end of the tubular member, said tubular member comprising:a first lumen extending axially within the tubular member, said first lumen adapted to carry blood between the patient and an external medical device; anda second lumen extending axially within the tubular member, which conducts fluid to inflate and deflate the balloon member, said second lumen extending to an opening which coincides in position with an interior of the balloon member.
