Abstract

A device for gripping a catheter, including a first jaw having a first exterior side and a first radial passage. The device has a second jaw having a second exterior side, opposite the first exterior side, and a second radial passage. The device also has a resilient joint connecting the first and second jaws so that manual compression of the first exterior side toward the second exterior side causes relative rotation between the first and second jaws that mutually aligns the first and second radial passages, such that the catheter can be inserted through the first and second radial passages, and so that releasing the manual compression causes the first and second jaws to rotate so that the first and second radial passages are no longer mutually aligned and so that the catheter passes through and is gripped by the device along mutually aligned first and second central axes.

First claim

We claim:

1. An assembly for gripping a catheter, the assembly comprising:
a central axis;
a first jaw body having:
a first grip surface on a first exterior side of the first jaw body,
a first opening extending through the first jaw body along an axis parallel to the central axis, and
a first passage;

a second jaw body having:
a second grip surface on a second exterior side of the second jaw body,
a second opening extending through the second jaw body along an axis parallel to the central axis, and
a second passage; and

a resilient joint;
wherein, in an assembled state, the resilient joint connects the first jaw body to the second jaw body in such a way that the first and second openings are aligned with the central axis;
wherein the first passage extends radially away from the first opening through the first jaw body to a first exit point on the first grip surface;
wherein the second passage extends radially away from the second opening through the second jaw body to a second exit point on the second grip surface;
wherein in a compressed state the first and second passages and the first and second exit points are mutually aligned, such that the catheter can be inserted through the first and second exit points along the first and second passages to the first and second openings; and
wherein in an uncompressed state the first and second passages and the first and second exit points are no longer mutually aligned and a portion of the first opening and a portion of the second opening are in alignment to form a tube-like opening, the tube like opening aligned with the central axis and dimensioned to grip a catheter in alignment with the central axis when the catheter is arranged through the tube-like opening.

2. The assembly according to claim 1 , wherein the first jaw body comprises a first plurality of first jaw leaves, and the second jaw body comprises a second plurality of second jaw leaves which interleave with the first jaw leaves.

3. The assembly according to claim 1 , wherein the first and second jaw bodies have identical geometric forms.

4. The assembly according to claim 1 , wherein the first grip surface comprises a first set of ridges and indentations, and the second grip surface comprises a second set of ridges and indentations.

5. The assembly according to claim 4 , wherein the first set and the second set of ridges and indentations align in a region in proximity to the first exit point and the second exit point upon release of the manual compression.

6. The assembly according to claim 4 , wherein the first jaw body, the second jaw body, and the resilient joint connecting the jaw bodies form a catheter grip, the device further comprising a cradle which is configured to receive the catheter grip.

7. The assembly according to claim 6 , wherein the cradle comprises a pawl which is configured to engage with at least a first indentation selected from the first and second sets of indentations and ridges so as to lock the catheter grip in place in the cradle.

8. The device assembly to claim 1 , wherein the catheter has a catheter diameter, and wherein release of the manual compression causes the first and second exterior sides to form a curved surface having a diameter at least 15 times greater than the catheter diameter.

9. The assembly according to claim 1 , wherein each one of the first and second openings comprises first and second half-circles separated by a preset distance, the first half-circle of the first opening defining a first opening portion of the tube-like opening and the second half-circle of the second opening defining a second opening portion of the tube-like opening.

10. The assembly according to claim 9 , wherein the preset distance is equal to the width of respective first and second passages.

11. The assembly according to claim 9 , wherein the half-circles have equal diameters corresponding to the diameter of a catheter to be grasped by grip.

12. A method for gripping a catheter, comprising:
providing an assembly comprising:
a first jaw body having:
a first grip surface on a first exterior side of the first jaw body,
a first opening extending through the first jaw body along an axis parallel to the central axis, and
a first passage extending radially away from the first opening;

a second jaw body having:
a second grip surface on a second exterior side of the second jaw body,
a second opening extending through the second jaw body along an axis parallel to the central axis, and
a second passage; and
a resilient joint;

wherein, in an assembled state, the resilient joint connects the first jaw body to the second jaw body in such a way that the first and second openings are aligned with the central axis;
wherein the first passage extends radially away from the first opening through the first jaw body to a first exit point on the first grip surface;
wherein the second passage extends radially away from the second opening through the second jaw body to a second exit point on the second grip surface;

manually compressing the assembly to cause a relative rotation between the first and second jaw bodies that misaligns the first and second openings with respect to the central axis, and mutually aligns the first and second radial passages and the first and second exit points with each other;
inserting a catheter through the first and second exit points and along the first and second radial passages to the first and second openings; and
releasing the manual compression to cause the first and second jaw bodies to rotate so that the first and second passages are no longer mutually aligned and portions of the first and second openings are arranged to form a tube-like opening;
wherein releasing the manual compression with the catheter located in the first and second openings causes the catheter to be gripped in alignment with the central axis by the tube-like opening.

13. The method according to claim 12 , wherein the first jaw body comprises a first plurality of first jaw leaves, and the second jaw body comprises a second plurality of second jaw leaves which interleave with the first jaw leaves.

14. The method according to claim 12 , wherein the first and second jaw bodies have identical geometric forms.

15. The method according to claim 12 , wherein the first grip surface comprises a first set of ridges and indentations, and the second grip surface comprises a second set of ridges and indentations.

16. The method according to claim 15 , wherein the first set and the second set of ridges and indentations align in a region in proximity to the first exit point and the second exit point upon release of the manual compression.

17. The method according to claim 15 , wherein the first jaw body, the second jaw body and the resilient joint connecting the jaw bodies form a catheter grip, the method further comprising providing a cradle which is configured to receive the catheter grip.

18. The method according to claim 17 , wherein the cradle comprises a pawl which is configured to engage with at least a first indentation selected from the first and second sets of indentations and ridges so as to lock the catheter grip in place in the cradle.

19. The method according to claim 12 , wherein the catheter has a catheter diameter, and wherein release of the manual compression causes the first and second exterior sides to form a curved surface having a diameter at least 15 times greater than the catheter diameter.

20. The method according to claim 12 , wherein each one of the first
