Abstract
The present invention enhances the effectiveness of treatment of support tissue structures. Generally, such tissue structures support organs and hold the organs in their proper position for appropriate functioning. When such tissue structures become weak, hyper-elastic, and/or excessively lengthy, the organs of are no longer supported in their proper position. This often leads to physical manifestations such as incontinence, hernias, and the like. Remedies often involve thermal treatment of the support tissue structures, such as thermally inducted controlled shrinkage, contraction, or stiffening of the support tissue structure. To enhance such thermal treatment and diminish the possibility of undesirable heating and damage to nearby tissue surfaces, vasoconstrictive agents are used.
