The purpose of this study is to test an investigational device called the Echopulse for treatment of breast fibroadenomas in women. Fibroadenomas are benign (noncancerous) breast tumors that are made of glandular and fibrous breast tissue. These lumps can occur alone, in groups, or as a complex of lumps together. Sometimes women feel these in the breast when doing regular self breast exams, or they may be found during a routine mammogram. Some are small (less than an inch in size), and others are quite large (the size of a lemon or larger).

This is a study about the Echopulse device, a computer driven system which uses ultrasound to guide a high intensity focused ultrasound beam to a targeted area (the fibroadenoma in the breast). The high intensity focused ultrasound (HIFU) heats the targeted site which causes the cells to die and allows the possibility to treat the fibroadenoma without the need for surgery.

Inclusion Criteria:

• Diagnosis of fibroadenoma with histological confirmation of fibroadenoma of the breast
• Fibroadenoma is palpable
• Fibroadenoma is 1 cm or greater at its largest dimension and no less than 9 mm in the anterior-posterior dimension
• Fibroadenoma volume is between 2 cc and 10 cc
• Patient must give written informed consent (personally signed and dated) before completing any study-related procedure

Exclusion Criteria:

• Patient is pregnant or nursing
• Patient with breast implants in the target breast
• Patient with a breast cyst within the fibroadenoma to be treated
• Patient participating in another clinical trial involving an investigational drug, device or biologic
