1. A medical assembly comprising:
two medical leads having distal electrodes;
a multiple lumen catheter configured to insert the two medical leads through a single opening to a defined space within a patient and further configured to be removed while the two medical leads remain inserted for subsequent delivery of stimulation pulses by the distal electrodes to the defined space, wherein the multiple lumen catheter comprises a distal end with a pre-formed bend, wherein the multiple lumen catheter comprises at least two lumen bodies; and
trocar present within a lumen of a first lumen body of the multiple lumen catheter, the trocar being positioned within the lumen at the distal end of the multiple lumen catheter such that the pre-formed bend is held straight.
