Abstract
The cryosurgical probe assembly with multiple deployable cryoprobes includes a) a housing assembly; b) a plurality of elongated structural support elements, each securely connected at a first end to the housing assembly; c) a tip member securely connected to second ends of the plurality of elongated structural support elements, the tip member including a plurality of cryoprobe openings; and, d) a plurality of cryoprobes each having a shaft thereon, each shaft being deployable through a respective cryoprobe opening during operation to a deployed position used for ablating tissue. In an alternate embodiment, a cylindrical housing is utilized rather than elongated structural support elements.
