Robotic catheter rotatable device cartridge
First Claim
Patent Images
1. A rotatable device cartridge for a robotic catheter system, the cartridge comprising:
- a housing having a longitudinal axis and configured for removable attachment to a drive head mechanism configured to rotate both the cartridge and a catheter coupled to the cartridge around the longitudinal axis;
a first slider block disposed along a first channel in the housing, wherein the first slider block is engaged with a first steering wire and is configured to move linearly parallel to the longitudinal axis to cause deflection of the catheter in a first direction; and
a second slider block disposed along a second channel in the housing, wherein the second slider block is engaged with a second steering wire and is configured to move linearly parallel to the longitudinal axis to cause deflection of the catheter in a second 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.

8. A robotic catheter rotatable device cartridge comprising:
-
a housing having a longitudinal axis and configured for removable attachment to a drive head configured to rotate the cartridge around the longitudinal axis; a first element disposed along a first channel of the housing and generally linearly movable parallel to the longitudinal axis, wherein the first element is engaged with a first steering wire and is configured to cause deflection of a surgically insertable device in a first direction; and a second element disposed along a second channel and generally linearly movable parallel to the longitudinal axis, wherein the second element is engaged with a second steering wire and is configured to cause deflection of the surgically insertable device in a second direction. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17)
