Abstract

A system for controlling a hemostasis valve includes a hemostasis valve having a body portion having a proximal end, a distal end and a lumen extending between the proximal end and the distal end. The hemostasis value further includes at least one valve positioned in the proximal end of the body portion and an engagement member operatively coupled to the at least one valve. The system further includes a first drive member coupled to the engagement member and a controller coupled to the first drive member. The controller is configured to control the first drive member to impart movement to the engagement member to open and close the at least one valve.

First claim

What is claimed is:

1. A system for controlling a hemostasis valve comprising:
a hemostasis valve comprising:
a body portion having a proximal end, a distal end and a lumen extending between the proximal end and the distal end;
at least one valve positioned in the proximal end of the body portion; and
an engagement member operatively coupled to the at least one valve;

the body portion of the hemostasis valve being pivoted from a raised position to an-in use position,
a first drive member removably coupled to the engagement member as the body portion of the hemostasis valve is pivoted to the in-use position and uncoupled from the engagement member as the hemostasis valve is pivoted to the raised position; and
a controller coupled to the first drive member, the controller configured to control the first drive member to impart movement to the engagement member to open and close the at least one valve.

2. The system according to claim 1 , wherein the controller is configured to incrementally adjust an amount the at least one valve is opened or closed.

3. The system according to claim 1 , wherein the first drive member imparts rotational movement to the engagement member; the engagement member rotates in a plane perpendicular to the longitudinal axis of the hemostasis valve.

4. The system according to claim 1 , wherein the first drive member imparts linear movement to the engagement member.

5. The system according to claim 1 , wherein the at least one valve is a Tuohy-Borst valve.

6. The system according to claim 1 , wherein the at least one valve is a bleedback valve.

7. The system according to claim 1 , wherein the at least one valve includes a bleedback valve and a Tuohy-Borst valve.

8. The system according to claim 1 further including a base and a support member supporting and pivoting the body portion of the hemostasis valve relative to the base from the raised position to the in-use position, wherein the body portion has a longitudinal axis that is in a first orientation relative to the base in the in-use position and a second orientation that non-colinear with the first orientation in the raised position.

9. A system for controlling a hemostasis valve comprising:
a base, and
a hemostasis valve comprising:
a body portion having a proximal end, a distal end and a lumen extending between the proximal end and the distal end;
at least one valve positioned in the proximal end of the body portion; and
an engagement member operatively coupled to the at least one valve;

the body portion being pivotable between a raised position to uncouple the engagement member to a drive member and an-in use position to couple the engagement member to the drive member, wherein the body portion has a longitudinal axis that is in a first orientation relative to the base in the in-use position and a second orientation that non-colinear with the first orientation in the raised position;
a sensor configured to detect at least one of blood flow or a frictional force; and
a controller coupled to the sensor and the engagement member, the controller configured to automatically control the drive member to operate the at least one valve based on the blood flow or frictional force detected by the sensor.

10. The system according to claim 9 , wherein the controller is configured to incrementally adjust an amount the at least one valve is opened or closed.

11. The system according to claim 9 , wherein the at least one valve is a Tuohy-Borst valve.

12. The system according to claim 11 , wherein the controller rotates the engagement member about a longitudinal axis of the hemostasis valve to increase or decrease a size of an opening of the at least one valve.

13. The system according to claim 9 , wherein the at least one valve is a bleedback valve.

14. The system according to claim 13 , wherein the controller translates the engagement member along a longitudinal axis of the hemostasis valve to open and close the at least one valve.

15. The system according to claim 9 , wherein the at least one valve includes a bleedback valve and a Tuohy-Borst valve.

16. The system according to claim 9 further including a support member moveably supporting the hemostasis valve from the raised position to the in-use position.

17. A system for controlling a hemostasis valve comprising:
a hemostasis valve comprising:
a body portion having a proximal end, a distal end and a lumen extending between the proximal end and the distal end;
at least one valve positioned in the proximal end of the body portion; and
an engagement member operatively coupled to the at least one valve;

a sensor configured to detect a frictional force required to move an elongated medical device; and
a controller coupled to the sensor and the engagement member, the controller configured to control the engagement member to operate the at least one valve based on the detected frictional force, wherein the sensor detects the frictional force required to robotically rotate the elongated device.

18. The system of claim 15 , wherein the controller automatically provides instructions to incrementally open or close the valve when the frictional force required to move the elongated medical device reaches a predetermined value.

19. The system of claim 18 , wherein the instructions to incrementally open or close the valve are based on both the frictional force required to move the elongated medical device through the valve and a patient's blood pressure.
