1. A probe device, comprising:
- a.) a collection fiber, said collection fiber comprising;
i.) a proximal end;
ii.) a distal collection end opposite said proximal end of the collection fiber, the distal collection end adapted to collect radiation; and
iii.) a conductive core located between said proximal end of the collection fiber and said distal collection end, said conductive core comprising a bend proximate to said distal collection end;
b.) a sheath encasing a portion of said collection fiber, said sheath comprising;
i.) a proximal end;
ii.) a distal end opposite said proximal end of the sheath; and
iii.) a core region located between said proximal end of the sheath and said distal end of the sheath, said core region of the sheath having an orifice in the wall of the sheath; and
c.) an anchoring balloon disposed on said sheath such that said orifice in said core region of the sheath is disposed inside the balloon and said distal end of the sheath is not disposed inside the balloon, said balloon having a wall,wherein said collection fiber is moveably disposed in said sheath, and wherein said bend deploys radially when said distal collection end is advanced through said orifice in said core region of the sheath thereby causing said distal collection end of said collection fiber to move into the interior of the balloon.

Abstract
Balloon probes, adapted for use in endoscopy and other medical procedures, are useful to obtain spectroscopic information reflected or emitted from a tissue of interest in the infrared spectral region. The information collected by the probe is useful in the diagnosis and treatment of disease. The invention also relates to methods utilizing these probes to analyze a surface of interest, in a minimally invasive manner, in connection with the diagnosis and treatment of disease.

17. A probe device, comprising
a.) a plurality of collection fibers, each respective collection fiber in said plurality of collection fibers comprising: -
i.) a proximal end; ii.) a distal collection end opposite said proximal end of the collection fiber, the distal collection end adapted to collect radiation; and iii.) a conductive core located between said proximal end of the collection fiber and said distal collection end, said conductive core comprising a bend proximate to said distal collection end, b.) a sheath, wherein said sheath encases a portion of each collection fiber in said plurality of collection fibers, said sheath comprising; i.) a proximal end; ii.) a distal end opposite said proximal end of the sheath; and iii.) a core region located between said proximal end of the sheath and said distal end of the sheath, said core region of the sheath having an orifice in the wall of the sheath; and c.) an anchoring balloon disposed on said sheath such that said orifice in said core region of the sheath is disposed inside the balloon and said distal end of the sheath is not disposed inside the balloon, said balloon having a wall, wherein each respective collection fiber in said plurality of collection fibers is moveably disposed in said sheath, and wherein the bend of each respective collection fiber in said plurality of collection fibers deploys radially when the distal collection end of the respective collection fiber is advanced through said orifice in said core region of the sheath thereby causing the distal collection end of the respective collection fiber to move into the interior of the balloon. - View Dependent Claims (18, 19, 20)
