Abstract
A cryogenic probe design is provided containing, for example, an inner coil injection tube with a continuous flow of circulating liquid and an outer jacket enclosing the inner coil injection tube. A transducer may monitor parameters in the region between the inner coil injection tube and the outer jacket. An outer jacket serves to prevent gas leakage. One or more embodiments of a probe design provide continuous flow for example via a continuous and controlled path from inlet to outlet and an expanded thermally transmissive region. Expanding a thermally transmissive region of the cooling zone may be provided, for example, in one or more embodiments of injection tube designs.
Claims31
A cryogenic probe comprising:
- an elongated tube comprising an injection tube, a coil and a return tube, wherein the coil comprises a first end a second end, said first end in fluid communication with said injection tube, and said second end in fluid communication with and directly and mechanically coupled to a distal end of said return tube;
- an outer jacket enclosing said coil, said outer jacket having an inner surface and an outer surface;
- an inner jacket comprising a proximal end and a distal end disposed within said outer jacket and forming a probe chamber, wherein said distal end of said inner jacket is disposed entirely within said outer jacket and wherein said distal end of said inner jacket is sealed, said inner jacket having an inner surface and an outer surface, wherein a space exists between the outer surface of said inner jacket and the inner surface of said outer jacket forming a jacket chamber;
- and
- a tip at the distal portion of the probe.
