1. A tissue modification device for the treatment of a tissue, comprising:
an elongate element having a proximal end and a distal end, wherein the elongate element is configured to be inserted into the tissue;
a first lumen in the elongate element configured to deliver a fluid into a working space in the tissue to flush the working space;
a pressure sensor to measure a pressure of the fluid and maintain the pressure of the fluid within a range;
an energy source disposed within the elongate element, wherein the energy source is configured to modify a volume of tissue through the working space; and
a second lumen in the elongate element to remove tissue products treated with the energy source.
