Abstract:
1. A catheter configured for omni-directional deflection of a distal portion, comprising: a first tubular component having a distal portion and a proximal portion, said proximal portion being substantially linear in shape and said distal portion including a preformed curvilinear section; a second tubular component having a distal portion and a proximal portion, said second component being configured for individual slidable movement and common rotational movement relative to said first component, to thereby allow said distal portion of said second component to slidably bear against said preformed curvilinear section of said first component; a shaft having a shaft orientation and a distal portion and a proximal portion and an inner lumen configured to accommodate said first and second tubular components; a controller including a base and configured (i) to effect a relative axial movement between said first and second tubular components and (ii) to effect a rotational movement of said first component and said second component while said shaft orientation remains in a fixed rotational position relative to said base; wherein said controller is housed in a catheter handle disposed at a catheter proximal end, said base comprising a handle housing, and wherein said shaft is fixed relative to said housing, said controller including a knob configured for manual actuation, said controller further including a first mechanism responsive to actuation of said knob configured to axially move said second tubular component relative to said first tubular component; wherein said housing has a cylindrical portion, said knob comprising an elongate ring radially outwardly of said cylindrical portion and wherein said ring has an internal gear disposed in an inner circumference thereof, said first mechanism including an input gear in mesh with said internal gear of said knob such that rotation of said knob causes rotation of said input gear, and wherein said first mechanism further includes: a spline shaft having a transfer gear in mesh with said input gear such that rotation of said input gear causes rotation of said spline shaft, said spline shaft further including a spline gear portion; a drive shaft having a spur gear in mesh with said spline gear portion of said spline shaft such that rotation of said spline shaft causes rotation of said drive shaft; said first tubular component being coupled to said drive shaft for rotation such that rotation of said drive shaft causes rotation of said first tubular component.
