Abstract
An aspiration baffle comprises an outer tube and an inner core wire. Microholes are provided in the outer tubular member to permit passage of gas but inhibit the passage of liquids. The aspiration baffle is used in a catheter having a balloon or other inflatable structure to assist in priming of the structure. After evacuating the inflatable structure by applying a vacuum, the aspiration baffle can collect and trap residual gas which remains during the priming of the inflatable structure.
