1. A catheter actuation handle assembly adapted to manipulate one or more distally-extending members that connect to the catheter handle and extend from the handle to locations distal from the handle for realizing translation, articulation and/or rotation of these distally-extending members using a combination of components comprising at least a moveable component that is connected to a distally-extending member and is actuated by an associated actuation component that can be manually manipulated, said handle assembly comprising:
at least a pair of mating exterior shell halves, each exterior shell half having an exterior shell outer surface and an exterior shell inner surface, the pair of exterior shell halves being mateable with one another to form a generally cylindrically-shaped actuation handle housing having a cross-sectional shape selected from circular and ovular, and the housing defines an exterior shell cavity and a handle longitudinal axis; at least a moveable component positioned inside the exterior shell cavity whereby the moveable component is enabled for linear movement along, and/or rotational movement about, the longitudinal axis, by engagement with one or more actuation components of the assembly; at least a connection between the moveable component and a distally-extending member; and, one or more access ports through the actuation handle housing providing access into the exterior shell cavity for manipulating the moveable component and/or the actuation component from outside the actuation handle housing; also wherein:
the actuation component comprises a pair of mating interior shell halves forming a cylindrically-shaped interior shell segment that is sized to fit inside and rotate within the exterior shell cavity;the moveable component comprises at least a first moveable driver;threading along an interior shell inner surface engages corresponding threading along an outer surface of the moveable driver whereby rotation of the interior shell segment via an associated access port causes linear movement of the moveable driver along the handle longitudinal axis; andthe handle assembly further comprises corresponding circumferential rib projections along the inner surfaces of the exterior shell halves and also along the outer surfaces of the interior shell halves to facilitate positioning and rotation of the interior shell inside the exterior shell cavity, and one or more knob features along the outer surface of the interior shell at locations where the knob features align with and project at least partly into or through an access port.
