Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
56 words
A catheter, comprising: (a) a housing having a transverse inner dimension of at most about two millimeters; and (b) a coil arrangement including at least five coils and at least five solid cores, each of said coils being wound around one of said cores, said coils being non-coaxial, said coil arrangement being mounted inside said housing.
Claim 2
Dependent Claim
56 words
A catheter, comprising: (a) a housing having a transverse inner dimension of at most about two millimeters; and (b) a coil arrangement including at least five coils and at least five solid cores, each of said coils being wound around one of said cores, said coils being non-coaxial, said coil arrangement being mounted inside said housing.
Claim 3
Dependent Claim
12 words
The catheter of claim 1 , wherein said solid cores includes ferrite.
Claim 4
Dependent Claim
28 words
The catheter of claim 1 , wherein said coils have an axis, said axes of at least three of said coils being substantially mutually perpendicular to each other.
Claim 5
Dependent Claim
25 words
The catheter of claim 1 , wherein each of said coils has a center, said centers of said coils lying on a substantially straight line.
Claim 6
Dependent Claim
108 words
A probe for interacting with a body cavity, comprising: (a) a substantially cylindrical catheter; (b) a satellite; being part of a sensing probe; (c) a flexible pocket having an aperture therein, said flexible being rigidly, attached to said catheter, said flexible pocket being configured for receiving said satellite therein; and (d) a tether passing through said aperture, said tether being attached to said satellite, such that, after said catheter and said satellite have been inserted into the body cavity, said tether is withdrawn, thereby pulling said satellite into said flexible pocket so as to reversibly secure said satellite at a fixed position and orientation relative to said catheter.
Claim 7
Dependent Claim
108 words
A probe for interacting with a body cavity, comprising: (a) a substantially cylindrical catheter; (b) a satellite; being part of a sensing probe; (c) a flexible pocket having an aperture therein, said flexible being rigidly, attached to said catheter, said flexible pocket being configured for receiving said satellite therein; and (d) a tether passing through said aperture, said tether being attached to said satellite, such that, after said catheter and said satellite have been inserted into the body cavity, said tether is withdrawn, thereby pulling said satellite into said flexible pocket so as to reversibly secure said satellite at a fixed position and orientation relative to said catheter.
Claim 8
Dependent Claim
25 words
The probe of claim 5 , wherein said mechanism includes: (i) a sleeve, rigidly secured to said tether and adapted to slide along said catheter.
Claim 9
Dependent Claim
20 words
The probe of claim 5 , wherein said sensor is configured for sensing a position and orientation of said catheter.
