Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
85 words
A medical appliance (1, 31, 61 101) for the treatment of a portion of body vessel by ionizing radiation, comprising radioactive radiation means (2, 32, 62, 102) and manipulation means (3, 33, 63, 103), characterized by at least a part (4, 34, 64, 104) of the radioactive radiation means making part of a detachable interlocking engagement (5, 9, 55, 99; 34, 36; 69, 66, 67, 68; 105, 106) between the radioactive radiation means (2, 32, 62, 102) and the manipulation means (3, 33, 63, 103).
Claim 2
Dependent Claim
45 words
A medical appliance according to claim 1, comprising proximal recess means (99, 67) and stone means (9, 66) on said radioactive radiation means (2, 62) for cooperation with distal recess means (5, 69) and stone means (55, 68) arranged on said manipulation means (3, 63).

Dependent Claim
27 words
A medical appliance according to claim 2, wherein said stone means (9) on said radioactive radiation means (2) is elastically connected to the radioactive radiation means (2).
Claim 4
Dependent Claim
33 words
A medical appliance according to claim 1, comprising proximal and distal wall means (104) on said radioactive radiation means (102) for cooperation with distal recess means (106) arranged on said manipulation means (103).
Claim 5
Dependent Claim
22 words
A medical appliance according to claim 4, wherein said distal recess means is formed by a deformation of said manipulation means (103).
