Abstract:
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, and a 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.
