Abstract
Abstract A surgical device for volumetric localization, biopsy and surgical procedures consists of a tubular shaft containing an array of filaments which are preformed and preloaded as springs. The filaments when deployed by extension from the tubular shaft, after insertion through or adjacent to a tumor or other tissue mass, form a predetermined, i.e., substantially closed loop, configuration outlining, encasing and excluding a known volume of tissue, i.e., tumor or other tissue mass, from the human body for the purpose of localization, biopsy or surgical removal. The filament array configuration, when outlining, enclosing and excluding the tumor or other tissue mass, limits tissue exposure to conventional and nonconventional forms of surgery to that within the encircling filaments.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
142 words
A surgical device for volumetric localization, biopsy and surgical procedures comprising a straight hollow tubular shaft of a size easily inserted into the human body through or adjacent to a tumor or tissue mass, a filament array positioned in said straight hollow shaft comprising a plurality of filaments of a spring deformable material having a substantially curved shape when unstressed and when straightened and positioned in said shaft being preloaded by the spring properties of the filaments, and means supporting said array of filaments and operable to move the same relative to said hollow shaft to extend said filaments from said hollow shaft to an unstressed position where said filaments assume said substantially curved shape for outlining, encasing and excluding a known volume of tumor or other tissue mass from the human body for the purpose of localization, biopsy or surgical removal.
Claim 2
Dependent Claim
142 words
A surgical device for volumetric localization, biopsy and surgical procedures comprising a straight hollow tubular shaft of a size easily inserted into the human body through or adjacent to a tumor or tissue mass, a filament array positioned in said straight hollow shaft comprising a plurality of filaments of a spring deformable material having a substantially curved shape when unstressed and when straightened and positioned in said shaft being preloaded by the spring properties of the filaments, and means supporting said array of filaments and operable to move the same relative to said hollow shaft to extend said filaments from said hollow shaft to an unstressed position where said filaments assume said substantially curved shape for outlining, encasing and excluding a known volume of tumor or other tissue mass from the human body for the purpose of localization, biopsy or surgical removal.
Claim 3
Dependent Claim
35 words
A surgical device according to claim 1 in which said supporting means comprises a stylet movable longitudinally in said hollow shaft and supporting said filament array for movement into and out of said hollow shaft.
Claim 4
Dependent Claim
20 words
A surgical device according to claim 1 in which said filaments have an unstressed configuration comprising a substantially closed loop.
Claim 5
Dependent Claim
47 words
A surgical device according to claim 1 in which said supporting means comprises a stylet movable longitudinally in said hollow shaft and supporting said filament array for movement into and out of said hollow shaft, and said filaments have an unstressed configuration comprising a substantially closed loop.
Claim 6
Dependent Claim
50 words
A surgical device according to claim 1 in which said supporting means comprises a stylet movable longitudinally in said hollow shaft and supporting said filament array for movement into and out of said hollow shaft, and said hollow shaft, filament array and stylet are formed of surgical steel or plastic.
Claim 7
Dependent Claim
113 words
A surgical procedure for volumetric localization, biopsy or surgical excision utilizing the surgical device of claim 1 which comprises inserting said hollow shaft into human body through or closely adjacent to a tumor or tissue mass with said filament array inside said hollow shaft, moving said filament array relative to said hollow shaft to extend said filaments from said hollow shaft to an unstressed position where said filaments assume said substantially curved shape outlining, encasing and excluding said tumor or tissue mass form the human body for the purpose of localization, biopsy or surgical removal, and subjecting the filament-encased tumor or tissue mass to removal or disintegration by a surgical or biopsy instrument.
Claim 8
Dependent Claim
23 words
A surgical procedure according to claim 6 in which said tumor or tissue mass is removed by a conventional surgical or biopsy instrument.
Claim 9
Dependent Claim
21 words
A surgical procedure according to claim 6 in which said tumor or tissue mass is removed by a laser surgical instrument.
Claim 10
Dependent Claim
21 words
A surgical procedure according to claim 6 in which said tumor or tissue mass is removed by a sonic surgical instrument.
Claim 11
Dependent Claim
39 words
A surgical procedure according to claim 6 in which said tumor or tissue mass is removed by manipulation of said tumor or tissue mass encasing fibers to cause said fibers to cut or shred said encased mass for removal.
Claim 12
Dependent Claim
21 words
A surgical procedure according to claim 6 in which said encased tumor or tissue mass is removed through said hollow shaft.
Claim 13
Dependent Claim
24 words
A surgical procedure according to claim 6 in which said fibers are removed after encasing said tumor or tissue mass through said hollow shaft.
Claim 14
Dependent Claim
24 words
A surgical procedure according to claim 10 in which said hollow shaft is removed and the encased tumor or tissue mass then surgically removed.
Claim 15
Dependent Claim
67 words
A surgical procedure according to claim 6 in which said hollow shaft is inserted through said tumor or tissue mass and said filament array moved to extend said filaments from said hollow shaft to an unstressed position where said filaments assume said substantially curved shape outlining, encasing and excluding said tumor or tissue means from the human body for the purpose of localization, biopsy or surgical removal.
Claim 16
Dependent Claim
71 words
A surgical procedure according to claim 6 in which said hollow shaft is inserted closely adjacent to but outside said tumor or tissue mass and said filament array moved to extend said filaments from said hollow shaft to an unstressed position where said filaments assume said substantially curved shape outlining, encasing and excluding said tumor or tissue mass from the human body for the purpose of localization, biopsy or surgical removal.
Claim 17
Dependent Claim
117 words
A surgical procedure for volumetric localization, biopsy or surgical excision utilizing the surgical device of claim 8 which comprises inserting said hollow shaft into a human body through or closely adjacent to a tumor or tissue mass with said filament array inside said hollow shaft, moving said filament array supporting stylet longitudinally relative to said hollow shaft to extend said filaments from said hollow shaft to an unstressed position where said filaments assume said substantially curved shape outlining, encasing and excluding said tumor or tissue mess from the human body for the purpose of localization, biopsy or surgical removal, and subjecting the filament-encased tumor or tissue mass to removal or disintegration by a surgical or biopsy instrument.
Claim 18
Dependent Claim
23 words
A surgical procedure according to claim 16 in which said tumor or tissue mass is removed by a conventional surgical or biopsy instrument.
Claim 19
Dependent Claim
43 words
A surgical procedure according to claim 16 in which said tumor or tissue means is removed by manipulation of said tumor or tissue mass encasing fibers by the supporting stylet to cause said fibers to cut or shred said encased mass for removal.
Claim 20
Dependent Claim
67 words
A surgical procedure according to claim 16 in which said hollow shaft is inserted through said tumor or tissue mass and said filament array moved to extend said filaments from said hollow shaft to an unstressed position where said filaments assume said substantially curved shape outlining, encasing and excluding said tumor or tissue mass from the human body for the purpose of localization, biopsy or surgical removal.
