The Lattice CO2 Laser system functions by delivering precise thermal energy and controlled ablation to vaginal tissue to stimulate deep structural remodeling. It utilizes an array of microscopic laser beams to trigger a natural healing response, ultimately restoring the tissue integrity required to support the urethra and prevent leakage.
Core Insight: The system does not merely tighten surface tissue; it initiates a physiological "repair mode" deep within the vaginal wall. by creating microscopic zones of thermal injury, the laser stimulates fibroblasts to produce new collagen and elastin, reinforcing the pelvic floor support structures that control urinary continence.
How the Laser Energy Interacts with Tissue
The fundamental mechanism relies on fractional micro-pore technology. Instead of treating the entire tissue surface at once, the system creates a pattern of microscopic wounds while leaving surrounding tissue intact.
Controlled Thermal Ablation
The system emits a specific wavelength (typically 10,600 nm) to create micro-ablation zones or "thermal damage islands" on the vaginal mucosa.
Preservation of the Epidermis
Because the energy is delivered in a fractional pattern, the heat penetrates to deep tissues without causing widespread damage to the surface epidermis.
Rapid Healing Response
The intact tissue bridges surrounding the micro-pores allow for a rapid wound-healing response, significantly minimizing recovery time compared to fully ablative procedures.
The Biological Regeneration Process
Once the thermal energy is delivered, it triggers a cascade of biological events known as tissue remodeling. This is where the actual therapeutic change occurs.
Activation of Heat Shock Proteins
The micro-ablative thermal effect induces the expression of heat shock proteins. This signals the body to begin synthesizing the extracellular matrix, which is the structural scaffolding of the tissue.
Collagen and Elastin Synthesis
The thermal injury triggers an inflammatory cascade that stimulates fibroblasts. These cells generate new collagen fibers and elastin, resulting in a thicker, healthier vaginal epithelium rich in glycogen.
Neoangiogenesis and Vasodilation
The process induces local vasodilation (widening of blood vessels) and neoangiogenesis (formation of new blood vessels). This mimics the effects of local estrogen therapy, improving blood supply, metabolism, and overall tissue health.
Restoring Urethral Function
The biological changes described above lead directly to the mechanical improvements necessary to treat stress urinary incontinence (SUI).
Tightening the Vaginal Wall
The synthesis of collagen and the contraction of fibers lead to a physical tightening and shrinking of the vaginal wall tissue.
Increasing Urethral Closure Pressure
By strengthening the connective tissues around the pelvic floor and urethral sphincter, the treatment increases urethral closure pressure. This restores the urethra's ability to stay closed during physical exertion, such as coughing or sneezing.
Understanding the Clinical Context
While the mechanism is highly effective for tissue regeneration, it is important to understand where this technology fits in the broader treatment landscape.
A Non-Surgical Alternative
Unlike invasive procedures such as tension-free vaginal tape (TVT), this mechanism requires no anesthesia or hospitalization. It eliminates risks associated with surgical mesh, such as erosion or chronic pain.
Target Patient Profile
The mechanism is most effective for mild to moderate stress urinary incontinence. It is particularly well-suited for perimenopausal and postmenopausal patients dealing with tissue atrophy or weakened pelvic support.
Making the Right Choice for Your Goals
The Lattice CO2 Laser is a tool for tissue rehabilitation rather than structural reconstruction.
- If your primary focus is safety and minimal downtime: This system offers a non-surgical solution that strengthens natural tissue without the risks of anesthesia or mesh implants.
- If your primary focus is treating mild to moderate leakage: The mechanism provides sufficient collagen remodeling to restore continence and improve symptoms of urgency and frequency.
Ultimately, the Lattice CO2 Laser works by harnessing the body's own regenerative capabilities to biologically reverse the tissue weakening that causes incontinence.
