Abstract
Catheterization employing a cable extending from the catheter to a fixed point of attachment is performed by providing a sensor to detect rotation of the catheter about its longitudinal axis, the rotation causing the cable to form a twist. The cable extends through a cable arranger that operates to remove the twist. A controller receives signals from the sensor and generates control signals to actuate the cable arranger responsively to the signals from the sensor.
Claims10
An apparatus, comprising:
- a catheter adapted for insertion into a living subject, the catheter having a longitudinal axis;
- a cable having one end attached to the catheter and another end at a fixed point of attachment;
- a sensor for detecting a twisting motion of the catheter about the longitudinal axis in a first rotary direction, the twisting motion causing a segment of the cable to form a twist in a portion of the cable;
- a cable arranger comprising a housing and a drive assembly operative for rotating the cable in a second rotary direction that tends to counteract the twisting motion in the first rotary direction for removing the twist from the portion of the cable;
- a controller receiving signals from the sensor and operative for generating control signals to actuate the drive assembly responsively to the signals of the sensor;
- and
- a torsion rod that extends out from the cable arranger, the torsion rod arranged to grip the cable;
- wherein the housing comprises a first radial slot;
- wherein the drive assembly comprises a drive gear with a second radial slot;
- and
- wherein the first radial slot is alignable with the second radial slot to enable ingress and egress of the cable therethrough.
