Patent ID: 8459266

Claim:
A sterile bag for an intravascular pullback system, comprising: an elongate bag defining a chamber sized to contain an intravascular pullback device having a motor drive and a sled, the motor drive being translatable along a longitudinal axis of the sled during use, the elongate bag comprising: an upper section and an opposing lower section, at least a portion of the upper section defining a plurality of folds adjacent a distal end of the elongate bag, each of the plurality of folds in the upper section extending a plane that is generally parallel to a plane defined by the lower section, the plurality of folds being movable between a folded configuration and an unfolded configuration, wherein in the folded configuration the plurality of folds are oriented in a step-wise manner descending from an uppermost fold positioned closest to the distal end, the plurality of folds being movable between the folded configuration and the unfolded configuration to facilitate expansion of the elongate bag to accommodate longitudinal translation of the motor drive along the sled, wherein the lower section does not include any folds adjacent the distal end of the elongate bag; and an orifice located adjacent to and proximal of the plurality of folds, the orifice sized to allow passage of a proximal portion of an intravascular device into the chamber of the bag in a direction parallel to the longitudinal axis and into engagement with the intravascular pullback device.
