1. A device for measuring temperatures at a predetermined plurality of points along a line of investigation within a body, said device comprising:
- a plurality of temperature sensors, each of said plurality of sensors corresponding to one of said predetermined points,a plurality of expandable mounting members, each mounting member having a first end and a second end thereon, each mounting member having one of said sensors mounted thereon, and,a plurality of spacer members disposed so that each first end and each second end of each of said plurality of expandable mounting members is adjacent to one of said spacers,said spacer members adapted to translate a force exerted along an axis extending through said device into a force directed radially outward relative to said axis, said spacer members also adapted to impress said radially outward directed force into each of said plurality of expandable mounting members to expand said mounting members in a radially outward direction to dispose said sensors in a temperature sensing relationship with said body.

Abstract
A multiple sensor temperature measuring device for measuring temperatures at a predetermined number of points along a line of investigation within a body is described. The device has a plurality of temperature sensors mounted on a corresponding plurality of expandable mounting members, each sensor being surrounded by electrical insulation and being contained within a protective sheath. The mounting members are expanded by suitable spacers to dispose the sheath in an abutting and temperature sensing relationship with the body at each predetermined point of interest therein.

9. A device for measuring temperatures at a predetermined plurality of points along a line of investigation within a body, said device comprising:
-
a plurality of temperature sensors, each sensor corresponding to a predetermined point and each disposed within and electrically insulated from a metallic sheath, a plurality of expandable mounting members each having a central cavity therein, said expandable mounting members comprising a substantially cylindrical member with a first and second end and having a slit extending completely along the length thereof and an opening therein, each mounting member having a sensor mounted on the outer surface of said slit cylindrical member adjacent said first end thereof, each of said sheaths of each sensor extending through said opening in each slit cylindrical member into said central cavity therein, and, means for expanding each of said expandable mounting members to dispose said sensors in a temperature sensing relationship with said body, said expanding means comprising; a plurality of spacer members being disposed so that each first end and each second end of each of said expandable members is adjacent to one of said plurality of spacer members, each of said first ends of said expandable members being disposed so as to overlap a predetermined portion of the spacer member adjacent said first end, each of said second ends of said expandable members being disposed in abutting contact with said spacer member adjacent said second end, said spacer members transferring a force imposed thereon in a direction along an axis extending through said device into each of said expandable members, each of said expandable members responding to said force imposed thereon by displacing in a direction tending to overlap a greater portion of said spacer member adjacent said first end, said displacement of said expandable members relative to said spacer members adjacent said first end so as to overlap said greater portion of said spacer member causing said expandable member to expand in a direction radially outward relative to said axis to dispose said sensor in said temperature sensing relationship with said body.
