An appropriate catheter and inflating apparatus havingbeen selected, the next step is the technique of inserting theinstrument. The plan which seems most simple will be firstdescribed, after which other methods will be detailed. The inflating bulb is held in the palm of the right hand,while the catheter, having been properly connected with it, isgrasped lightly between the thumb and index and middle fin-gers of this hand, much asa pen is held.
