Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
148 words
Apparatus suitable for hyperthermic treatment of tumours in the vicinity of the anal body cavity whereby the cavity mucosa and the cavity walls are cooled while simultaneously heating said tumours, said apparatus comprising: probe means (101) arranged to be insertable into the body cavity and including; a housing having forward and intermediate surfaces (102, 104); radiation-producing antenna means (108; 130) disposed in said housing; and cooling conduit means (116) disposed peripherally of said housing and arranged to receive cooling fluid for cooling body tissue disposed in propinquity thereto, said cooling conduit means comprising a flexible conduit, characterized by said flexible conduit (116) being coiled about the outside forward peripheral surface (102) of said housing, whereby it may be compressed upon insertion into the anal cavity and expanded forwardly of the sphincter muscle when coolant passes therethrough for secure engagement in said cavity, thus retained by the sphincter muscle.
Claim 2
Dependent Claim
148 words
Apparatus suitable for hyperthermic treatment of tumours in the vicinity of the anal body cavity whereby the cavity mucosa and the cavity walls are cooled while simultaneously heating said tumours, said apparatus comprising: probe means (101) arranged to be insertable into the body cavity and including; a housing having forward and intermediate surfaces (102, 104); radiation-producing antenna means (108; 130) disposed in said housing; and cooling conduit means (116) disposed peripherally of said housing and arranged to receive cooling fluid for cooling body tissue disposed in propinquity thereto, said cooling conduit means comprising a flexible conduit, characterized by said flexible conduit (116) being coiled about the outside forward peripheral surface (102) of said housing, whereby it may be compressed upon insertion into the anal cavity and expanded forwardly of the sphincter muscle when coolant passes therethrough for secure engagement in said cavity, thus retained by the sphincter muscle.
Claim 3
Dependent Claim
16 words
Apparatus according to claim 1 and wherein said coiled conduit (116) defines a ribbed outer surface.
Claim 4
Dependent Claim
44 words
Apparatus according to claim 1 and wherein said housing defines a relatively broad cross section forward portion (102) and a narrower intermediate portion (104), said forward portion having said antenna means (108, 130) defined therein and being surrounded by said cooling conduit means (166).
Claim 5
Dependent Claim
16 words
Apparatus according to claim 1 and wherein said probe means also comprises temperature sensing means (12).
Claim 6
Dependent Claim
35 words
Apparatus according to claim 4 and wherein said temperature sensing means (12) comprise means for sensing the temperature at tissue adjacent said probe means along the radiation path between said antenna means and a tumour.
Claim 7
Dependent Claim
26 words
Apparatus according to claim 4 and wherein said temperature sensing means (12) comprise means for sensing the temperature in the vicinity of or inside said tumour.
Claim 8
Dependent Claim
23 words
Apparatus according to claim 4 and wherein said temperature sensing means (12) comprise means for sensing the temperature within said cooling conduit means.
Claim 9
Dependent Claim
31 words
Apparatus according to claim 4 and also comprising means (14, 16, 18) for governing the power radiated by said antenna means in accordance with the temperature sensed by temperature sensing means.
