Abstract
Abstract An endoprobe includes a tubular element having a proximal end and a distal end. At least one optical fiber element is disposed within the tubular element. A plurality of laser light outlets are defined through a side wall of the tubular element. The at least one optical fiber element is adapted to conduct laser light from the proximal end of the tubular element to the plurality of laser light outlets, thereby to direct laser light radially of the tubular element. The tubular element is arcuately curved along a portion of its length, adjacent its distal end and the laser light outlets are defined along a radially inner portion of the curved portion.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
110 words
An endoprobe comprising: a tubular element having a proximal end and a distal end; at least one optical fiber element disposed within said tubular element; and a plurality of laser light outlets defined through a side wall of said tubular element, said at least one optical fiber element being adapted to conduct laser light from said proximal end of said tubular element to said plurality of laser light outlets, thereby to direct laser light radially of the tubular element, wherein said tubular element is arcuately curved along portion of its length, adjacent its distal end, said laser light outlets being defined along a radially inner portion of said curved portion.
Claim 2
Dependent Claim
110 words
An endoprobe comprising: a tubular element having a proximal end and a distal end; at least one optical fiber element disposed within said tubular element; and a plurality of laser light outlets defined through a side wall of said tubular element, said at least one optical fiber element being adapted to conduct laser light from said proximal end of said tubular element to said plurality of laser light outlets, thereby to direct laser light radially of the tubular element, wherein said tubular element is arcuately curved along portion of its length, adjacent its distal end, said laser light outlets being defined along a radially inner portion of said curved portion.
Claim 3
Dependent Claim
20 words
An endoprobe as claimed in claim 1, wherein a plurality of optical fiber elements are disposed within said tubular element.
Claim 4
Dependent Claim
54 words
An endoprobe as claimed in claim 1, further comprising means for transporting fluids near a surgical area, said fluid transporting means being disposed within said tubular element and permitting fluids to be delivered to said surgical area for cooling thereof, said fluid transporting means permitting unwanted fluids to be removed from said surgical area.
Claim 5
Independent Claim
155 words
An apparatus for shrinking and coagulating body tissue comprising: an optical fiber endoprobe including a tubular element having a proximal end and a distal end, at least one optical fiber element being disposed within said tubular element, a plurality of laser light outlets being defined through a side wall of said tubular element, said at least one optical fiber element being adapted to conduct laser light from said proximal end of said tubular element to said plurality of laser light outlets, thereby to direct laser light radially of the tubular element; and a laser system coupled to said optical fiber endoprobe for delivering at least one laser light beam to said optical fiber endoprobe so as to shrink and coagulate the body tissue, wherein said tubular element is arcuately curved along a portion of its length, adjacent its distal end, said laser light outlets being defined along a radially inner portion of said curved portion.
Claim 6
Independent Claim
155 words
An apparatus for shrinking and coagulating body tissue comprising: an optical fiber endoprobe including a tubular element having a proximal end and a distal end, at least one optical fiber element being disposed within said tubular element, a plurality of laser light outlets being defined through a side wall of said tubular element, said at least one optical fiber element being adapted to conduct laser light from said proximal end of said tubular element to said plurality of laser light outlets, thereby to direct laser light radially of the tubular element; and a laser system coupled to said optical fiber endoprobe for delivering at least one laser light beam to said optical fiber endoprobe so as to shrink and coagulate the body tissue, wherein said tubular element is arcuately curved along a portion of its length, adjacent its distal end, said laser light outlets being defined along a radially inner portion of said curved portion.
Claim 7
Dependent Claim
57 words
An apparatus as claimed in claim 4, wherein said endoprobe further includes: means for transporting fluids near a surgical area, said fluid transporting means permitting fluids to be delivered to said surgical area for cooling thereof, said fluid transporting means being disposed within said tubular element and permitting unwanted fluids to be removed from said surgical area.
