Methods and devices useful in stage cementing operations are provided. One example of an apparatus may comprise a catcher tube assembly and a deformable device. One example of a method is a method of stage cementing a casing string comprising: positioning a catcher tube on top of a float collar; pumping a first fluid through the casing string; placing a first deformable device in the casing string; and pumping a second fluid through the casing string, thereby causing the first deformable device to translate downward in the casing string and into the catcher tube.
