Abstract

A system comprising a platform assembly comprising a master platform and a slave platform, both the master platform and the slave platform being moveable, the platform assembly further comprising a force feedback control arrangement for applying a force to the master platform in response to a force exerted on a slave device mounted on the platform.

Claims (22)

1. A system comprising:

a platform assembly comprising a master platform and a slave platform, both the master platform and the slave platform being moveable, the platform assembly further comprising a force feedback control arrangement for applying a force to the master platform in response to a force exerted on a slave device mounted on the slave platform,

wherein the master platform is adapted to support a master device, and the slave platform is adapted to support the slave device, and

wherein the slave device includes a catheter and the master device includes a hollow tube, coaxially mounted with respect to the catheter, and in use, axially overlapping with the catheter.

2. A system according to claim 1 comprising a movement control arrangement for causing the slave platform to move in response to movement of the master platform.

3. A system according to claim 1 wherein, in use, the master device is engageable with the slave device.

4. A system according to claim 1 wherein the slave device comprises a key engageable with a keyway formed in the master device.

5. A system according to claim 1 wherein the slave platform and the master platform are both independently moveable.

6. A system according to claim 1 comprises a first actuator operatively connected to the slave device for enabling movement of the slave platform.

7. A system according to claim 1 comprising a movement detector having a first movement component mounted on the master platform, and a second movement component mounted on the slave platform.

8. A system according to claim 1 comprising a strain gauge mounted at a proximal end of the slave device.

9. A system according to claim 1 comprising a force sensor for measuring force between the master device and the master platform.

10. A system according to claim 1 comprising a second actuator operatively connected to the master device for applying resistive force to the master device in response to forces applied to a distal portion of the catheter.

11. A system according to claim 1 comprising a switch for enabling activation/deactivation of the force feedback control arrangement.

12. A method according to claim 1 for inserting a catheter into a vessel in a human or animal body using a system according to any one of the preceding claims.

13. A system according to claim 7 comprising a first controller operatively connected to the movement detector and to the first actuator to form the movement control arrangement.

14. A system according to claim 8 comprising a second controller operatively connected to the strain gauge, the force sensor and the second actuator to form the force feedback control arrangement.

15. A system comprising:

a platform assembly comprising a master platform and a slave platform, the slave platform being adapted to move in response to movement of the master platform, the system further comprising a master device, and a slave device,

wherein the slave device includes a catheter and the master device includes a hollow tube, coaxially mounted with respect to the catheter, and in use, axially overlapping with the catheter whereby, in use, the master device is engageable with the slave device.

16. A system according to claim 15 comprising a force feedback control arrangement for applying a force to the master platform in response to a force exerted on the slave device.

17. A system according to claim 15 comprising a movement control arrangement for causing the slave platform to move in response to movement of the master platform.
