Abstract
A device and method for inflating and deflating a balloon, used to protect the cerebrum against emboli, during carotid stenting, is provided wherein the device comprises a balloon carried on a guide wire and wherein inflation can be accomplished without the need of a port on the guide wire, so that coaxial systems may be applied over the guide wire. The device comprises a guide wire having an interior lumen and a balloon that communicates with the lumen. A core segment is inserted into the open end of the guide wire, and serves as a piston to inflate the balloon after saline is introduced into the lumen. A locking mechanism is provided to retain the core segment in position during the procedure. Coaxial systems, such as balloon catheters and stent delivery systems, can be applied over the guide wire without deflating the guide wire balloon.
