In certain examples, marks along the catheter shaft provide visual verification to the physician of the relative position of the therapeutic element of the catheter. Embodiments of indexing devices may include pairs of rings and/or hinged arms that move a catheter a desired indexed position between successive treatments.

An interactive control unit is disclosed. The interactive control unit includes an interactive touchscreen display, an interface configured to couple the control unit to a surgical hub, a processor, and a memory coupled to the processor. The memory stores instructions executable by the processor to receive input commands from the interactive touchscreen display located inside a sterile field and transmit the input commands to the surgical hub to control devices coupled to the surgical hub located outside the sterile field.

A surgical instrument comprising a housing, a shaft, a loading unit, a firing member configured to perform a firing stroke, a motor, a battery, a firing trigger, a control system, an electronic lockout, and a firing trigger lockout is disclosed. The electronic lockout is configured to prevent the firing member from performing the firing stroke when the loadinq unit is not attached to the shaft. The electronic lockout is further configured to prevent the firing member from performing the firing stroke when the loading unit is attached to the shaft and the loading unit has been at least partially fired. The firing trigger lockout is in a locked position when the loading unit is not attached to the elongate shaft. The firing trigger lockout is in the locked position when the loading unit is attached to the elongate shaft and the loading unit has been at least partially fired.
