Abstract
A cryosurgery apparatus is disclosed. The cryosurgery apparatus an introducer having a hollow and a distal portion, the distal portion being sufficiently sharp so as to penetrate into a body, the hollow of the introducer being designed and constructed for containing a plurality of cryoprobes each of the cryoprobes being for effecting cryoablation, such that each of the plurality of cryoprobes is deployable through the distal portion of the introducer when the distal portion is positioned with respect to a tissue to be cryoablated.
Claims49
A cryosurgery apparatus comprising:
- a) a sheath forming a first hollow and having a distal portion, said distal portion being sufficiently sharp so as to penetrate into a body, said first hollow being designed and constructed for containing a plurality of cryoprobes each of said cryoprobes being controllably operable in itself for effecting cryoablation, wherein said first hollow further comprises
- i) a first Joule-Thomson heat exchanger having a first Joule-Thomson orifice, for heating and cooling said first hollow;
- and
- ii) a first heat exchanging configuration;
- and
- b) said plurality of cryoprobes, wherein at least one of said cryoprobes comprises
- iii) a second Joule-Thomson heat exchanger having a second Joule-Thomson orifice, for heating and cooling said cryoprobe;
- and
- iv) a second heat-exchanging configuration for pre-cooling and pre-heating high-pressure gas delivered to said second Joule-Thomson orifice;
- said plurality of cryoprobes being deployable through said distal portion of said sheath when said distal portion is positioned with respect to a tissue to be cryoablated, and each of said cryoprobes being controllably operable in itself for exerting said cryoablation when so deployed.
