Abstract
Abstract A catheter has an electrode tip assembly that is bendable at the selection of the user in two different directions. The electrode tip assembly assumes different asymmetric predetermined curve configurations when bent in the two directions and is manipulated by means of steering wires adjustably connected tangentially to the lateral edges of a rotatable cam located in the catheter handle.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
123 words
A steering assembly for applying bending forces to a flexible body, comprising: a handle; a moveable component moveably connected to said handle; first and second steering wires each having a proximal end attached to said moveable component and a distal end attached to the flexible body, wherein movement of said moveable component in a first direction applies tension to said first steering wire causing the flexible body to bend in a first multitude of selected curved shapes, and movement of said moveable component in a second direction applies tension to said second steering wire causing said flexible body to bend in a second multitude of selected curved shapes, said first multitude of curved shapes being different from said second multitude of curve shapes.
Claim 2
Dependent Claim
123 words
A steering assembly for applying bending forces to a flexible body, comprising: a handle; a moveable component moveably connected to said handle; first and second steering wires each having a proximal end attached to said moveable component and a distal end attached to the flexible body, wherein movement of said moveable component in a first direction applies tension to said first steering wire causing the flexible body to bend in a first multitude of selected curved shapes, and movement of said moveable component in a second direction applies tension to said second steering wire causing said flexible body to bend in a second multitude of selected curved shapes, said first multitude of curved shapes being different from said second multitude of curve shapes.
Claim 3
Dependent Claim
28 words
The steering assembly of claim 1 , comprising a guide tube having a distal end attached to the flexible body and a proximal end attached to said handle.
Claim 4
Dependent Claim

Claim 9
Dependent Claim
143 words
A steering assembly for applying bending forces to a flexible body, comprising: a handle; a moveable component moveably coupled to said handle; first and second steering wires each having a proximal end attached to said moveable component and a distal end attachable to the flexible body, wherein the steering assembly is adapted to cause an attached flexible body to bend in a first multitude of selected curved shapes in response to tension in said first steering wire caused by movement of said moveable component in a first direction, and is further adapted to cause an attached flexible body to bend in a second multitude of selected curved shapes in response to tension in said second steering wire caused by movement of said moveable component in a second direction, said first multitude of curved shapes being different from said second multitude of curve shapes.
Claim 10
Dependent Claim
143 words
A steering assembly for applying bending forces to a flexible body, comprising: a handle; a moveable component moveably coupled to said handle; first and second steering wires each having a proximal end attached to said moveable component and a distal end attachable to the flexible body, wherein the steering assembly is adapted to cause an attached flexible body to bend in a first multitude of selected curved shapes in response to tension in said first steering wire caused by movement of said moveable component in a first direction, and is further adapted to cause an attached flexible body to bend in a second multitude of selected curved shapes in response to tension in said second steering wire caused by movement of said moveable component in a second direction, said first multitude of curved shapes being different from said second multitude of curve shapes.
Claim 11
Dependent Claim
29 words
