Cryosurgical System with Low Pressure Cryogenic Fluid Supply

Abstract

A liquid cryogen fluid system for providing cryogenic liquid to a cryoprobe in a cryosurgical system for treating fibroadenomas and other lesions in the body. The system includes a cryoprobe to cryoablate a fibroadenoma with a treatment regimen that takes less time and consumes less cryogen than currently accepted regimens.

A fibroadenoma is a benign tumor found in women's breasts. They are small, solid, round, rubbery masses that are typically found in breast self-exams or mammography. Fibroadenomas are harmless, but may be painful, palpable and emotionally bothersome, and the may mask other lesions that would otherwise be visible to mammography. Fibroadenomas are removed to alleviate pain and to alleviate the emotional burden of living with a breast lump. Even when the breast lump is confirmed to be a benign fibroadenoma, many women elect removal for thes...

Problems solved by technology

Fibroadenomas are harmless, but may be painful, palpable and emotionally bothersome, and the may mask other lesions that would otherwise be visible to mammography.

Open surgical recision requires a fairly large incision, creates an unsightly scar on the breast and a scar inside the breast that interferes with mammography, and it requires general anesthesia.
