The Her Option® Cryoablation Therapy System is a closed-loop cryosurgical device that is used to ablate the endometrial lining in pre-menopausal women with menorrhagia (excessive menstrual bleeding) due to benign causes. This is a non-incisional procedure, which can be perfomed in a physicians office with minimal sedation.

Initial FDA clinical studies were conducted with a two-freeze treatment pattern consisting of a 4 minute freeze with the Cryoprobe positioned in one cornu followed by a second freeze of 6 minutes with the Cryoprobe repositioned in the contralateral cornu.

Since completion of the early studies, many physicians have experimented with varying freeze patterns using longer freeze durations and/or additional freezes at the fundus and the lower uterine segment. The results, as reported in the literature, indicate that these extended freeze patterns produce significantly better results than the original regimen.

Further study details as provided by American Medical Systems:

Primary Outcome Measures:
  • Evaluate the efficacy of the study treatment in reducing menstrual bleeding levels.

Secondary Outcome Measures:
  • Relieving pain/discomfort attributed to abnormal uterine bleeding (AUB) and improving quality of life.
  • Monitor the occurrence of side effects and/or complications associated with the study treatment.

Estimated Enrollment: 76
Study Start Date: April 2004
Estimated Study Completion Date: March 2008
Detailed Description:
American Medical Systems, Inc. (AMS) believes that the original treatment pattern used to support a previous FDA approval for the Her Option® Cryoablation Therapy System for Treatment of abnormal uterine bleeding was not optimal and that extended freeze regimens will result in improved outcomes for patients.
