Cellulite treatment system and methods

A system for treating an appearance of cellulite on skin of a patient, the system comprising:

• a handle;
• a first member extending distally from the handle, the first member being configured to be inserted through the skin;
• a second member configured to expand relative to the first member, wherein the second member is generally longitudinally aligned with the first member in a stowed configuration and configured to engage one or more regions of septa subcutaneously when expanded, wherein the second member has a septa hooking structure and a septa severing or disrupting structure;
• and
• a light transmitting assembly coupled to the first member and including a light source, a spherical lens, and a light fiber.

A method for treating an appearance of cellulite on skin of a patient, the method comprising:

• advancing a cellulite treatment system along a superficial path to a target site between tissue layers connected by a septum, the cellulite treatment system having a mechanical septa disrupting element and a septa hooking element;
• deploying the septa hooking element to a first position in which the septa disrupting element is shielded;
• engaging the septum and pulling the septum a distance of about 10 to 20 mm to determine that the septum is associated with the appearance of cellulite;
• transitioning the septa hooking element to a second position to expose the septa disrupting element;
• and
• separating the septum.
