1. A robotic catheter rotatable device cartridge having a longitudinal axis, the cartridge comprising:
- a housing member configured for removable attachment to a drive head and a drive mechanism configured to rotate both the cartridge and a catheter attached to the cartridge around the longitudinal axis of the cartridge;
a first slider block generally slidable relative to the housing along the longitudinal axis, wherein the first slider block is engaged with a first steering wire and is configured for engagement with a first portion of the drive head such that movement of the first portion of the drive head along the longitudinal axis is configured to cause corresponding movement of the first slider block along the longitudinal axis, and wherein the first slider block is configured to move linearly along the longitudinal axis to cause deflection of the catheter in a first direction transverse to the longitudinal axis, anda second slider block generally slidable relative to the housing along the longitudinal axis, wherein the second slider block is engaged with a second steering wire and is configured for engagement with a second portion of the drive head such that movement of the second portion of the drive head along the longitudinal axis is configured to cause corresponding movement of the second slider block along the longitudinal axis, and wherein the second slider block is configured to move linearly along the longitudinal axis to cause deflection of the catheter in a second direction transverse to the longitudinal axis, wherein the second direction is different than the first direction.

Abstract
A robotic catheter rotatable device cartridge may include a housing member attachable to a drive mechanism for rotating the cartridge and a catheter attached to the cartridge along an axial direction of the catheter. A slider block may be generally slidable relative to the housing and engaged with one or more steering wires for controlling movement of the catheter in a transverse direction relative to the axial direction. The catheter may include the steering wire(s) engaged therewith and movable in the transverse direction when the slider block is linearly driven in a predetermined direction.
