Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
186 words
A catheter accommodating an electrical wire therein, comprising: an elongated catheter member having a plurality of elongated cavities provided therein, said cavities extending in a longitudinal direction of the elongated catheter member, said elongated catheter member being stretchable form a first length in an unstretched state to a longer length in a stretched state; a sensor arranged in one of said elongated cavities; and an elongated electrical wire arranged in said one of said cavities and electrically connecting to the sensor the length of said electrical wire extending along the length of said one of said cavities and having a length greater than said first unstretched length and being accommodated in said one of said cavities with slack, whereby an excess length of said electrical wire is accommodated in said one of said cavities; an enlargement formed in only a portion of the length of said one of said cavities; and substantially all of said excess length of said electrical wire with respect to the length of the elongated catheter ember in an unstretched state of the elongated catheter member being accommodated slack in said enlargement.
Claim 2
Dependent Claim
186 words
A catheter accommodating an electrical wire therein, comprising: an elongated catheter member having a plurality of elongated cavities provided therein, said cavities extending in a longitudinal direction of the elongated catheter member, said elongated catheter member being stretchable form a first length in an unstretched state to a longer length in a stretched state; a sensor arranged in one of said elongated cavities; and an elongated electrical wire arranged in said one of said cavities and electrically connecting to the sensor the length of said electrical wire extending along the length of said one of said cavities and having a length greater than said first unstretched length and being accommodated in said one of said cavities with slack, whereby an excess length of said electrical wire is accommodated in said one of said cavities; an enlargement formed in only a portion of the length of said one of said cavities; and substantially all of said excess length of said electrical wire with respect to the length of the elongated catheter ember in an unstretched state of the elongated catheter member being accommodated slack in said enlargement.
Claim 3
Dependent Claim
75 words
The catheter of claim 1, wherein; the elongated catheter member includes a catheter body and an extension tube connected to the catheter body; said enlargement comprising an internal diameter-enlarged portion formed in at least part of at least one of said catheter body and said extension tube; and said excess length of said electrical wire corresponding to a maximum elongation of said catheter body and extension tube is accommodated slack in said internal diameter-enlarged portion.
Claim 4
Dependent Claim
93 words
The catheter of claim 1, wherein: the elongated catheter member includes a catheter body, an extension tube, and a connecting body having one end which is connected to said catheter body and another end which is connected to the extension tube; said enlargement comprising an internal diameter-enlarged portion formed in at least one of said catheter body, said extension tube and said connecting body; and said excess length of said electrical wire corresponding to a maximum elongation of said catheter body and said extension tube is accommodated slack in the internal diameter-enlarged portion.
Claim 5
Dependent Claim
34 words
The catheter of claim 3, wherein: at least one of said catheter body and extension tube has said plurality of cavities therein; and wires are accommodated separately in each of said plurality of cavities.
Claim 6
Dependent Claim
29 words
The catheter of claim 1, wherein the length of excess electrical wire accommodated in said enlargement is not less than 10% of a maximum elongation of said catheter member.
Claim 7
Dependent Claim
23 words
The catheter of claim 1, wherein said excess length of electrical wire accommodated in said enlargement is in the form of a coil.
Claim 8
Dependent Claim
51 words
The catheter of claim 1, wherein: said elongated catheter member comprises a catheter body having a distal tip portion and a proximal base portion; said sensor is arranged in said distal tip portion of said catheter body; and said enlargement is formed in said proximal base portion of said catheter body.
Claim 9
Dependent Claim
28 words
The catheter of claim 1, wherein said sensor and said electrical wire are exclusively provided in said one of said elongated cavities which has said enlargement formed therein.
Claim 10
Dependent Claim
19 words
The catheter of claim 1, wherein said enlargement comprises an internal diameter-enlarged portion of said one of said cavities.
Claim 11
Dependent Claim
20 words
The catheter of claim 1, wherein said enlargement comprises an enlarged internal cross-sectional portion of said one of said cavities.
