Claim:
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 at a proximal end of said shaft and 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 relative to said shaft while said shaft orientation remains in a fixed rotational position relative to said base, said base comprising a handle housing, said controller including a knob configured for manual actuation wherein said knob comprises a ring disposed radially outwardly of said handle housing, wherein said knob is configured for movement relative to said handle housing, said controller being responsive to actuation of said knob to effect said relative axial movement and said rotational movement, wherein said first and second components are in a relation selected from the group comprising a first concentric arrangement where said first tubular component is received within a central lumen of said second tubular component; and a second concentric arrangement where said second component is received within a central lumen of said first tubular component, said first and second components are concentric with said shaft over said proximal portion of said shaft including said proximal end and said distal portion of said shaft.
