HIGH PRESSURE PRE-BURST FOR IMPROVED FLUID DELIVERY

摘要

A needle with multiple injection ports is used in connection with a high-pressure injection system to infuse a treatment solution into a treatment area below the dermis of the skin. The needle has multiple tines that extend outwardly from the injection ports while inside the treatment area to disrupt tissue in the treatment area and to create multiple pathways of infusion. The tines are withdrawn and the needle is partially withdrawn, and solution is injected from the needle into the treatment area at high pressure to infuse the tissue within the treatment area. The burst, infusion, and a treatment such as an energy or third solution may be interleaved and repeated multiple times.
