About

This clinical trial will collect data on the safety and efficacy of the miraDry treatment when High Volume Anesthesia (Tumescent Anesthesia) is used as an alternate method of anesthetizing the axilla prior to the miraDry System being used. MiraDry system was FDA cleared in 2011 for the treatment of primary axillary hyperhidrosis. The miraDry system is also CE-marked.

Full description

Hyperhidrosis is a condition defined as sweating beyond what is physiologically required by the body (excessive sweating). Hyperhidrosis sufferers have been shown to suffer from anxiety, social and occupational impairment and limitation of exercise, recreation, and leisure. In addition to psychological and social issues, hyperhidrosis sufferers see significant financial burden from their condition. The costs of treatments which need to be repeated chronically and replacing clothing which is permanently stained and unwearable can amount to significant expenditures over time.

Many physicians using the miraDry System are using alternative methods for anesthetizing the axilla; the most common is infiltrative local tumescent anesthesia (LTA) at a high volume. miraDry often calls this method as High Volume Anesthesia (HVA) and the two terms are used interchangably. Tumescent anesthesia is commonly used for various dermatologic surgery procedures. This method involves using a larger volume of fluid with a lower concentration of lidocaine; the fluid is introduced under the skin through a few small injection sites and infiltrated into the desired region. For this application using the tumescent technique, between 100 and 300 cc's of fluid per axilla would be introduced subcutaneously, depending on the size of the axilla.

This clinical trial will collect data on the safety and efficacy when High Volume Anesthesia is used as an alternate method of anesthetizing the axilla prior to the miraDry System being used. The investigators participating in this study are experts in the administration of tumescent anesthesia for dermatologic applications.
