| 摘要 |
The present invention is of a cryotherapy apparatus which provides multiple cryoprobe operating tips in a configuration which enhances flow of exhaust gasses and thereby facilitates achieving cold temperatures and high thermal transfer capacity. The apparatus comprises a plurality of operating tips insertable in a body, each with a distal gas input lumen, a cryogen expansion chamber and a distal gas exhaust lumen, and a medial portion also insertable in a body and which comprises a medial gas exhaust lumen formed as a manifold communicating with the plurality of distal gas exhaust lumens.
