A new simplified cryosurgical instrument: the Foster Froster.
The authors report in detail the development of a simplified, yet highly efficient cryosurgical instrument. It is lightweight, portable, inexpensive, and easy to use. Studies show it to be comparable in most instances to a popular contemporary unit. Its chief drawback appears to be that it cannot serve as a liquid nitrogen reservoir for extended periods, although it can be used for multiple procedures without re-filling.
