Abstract

An endovascular delivery device (1) has a portion, such as the nose cone dilator (8), being formed from a radiopaque material and that portion has a selected transverse profile such as a notch (26) so that in a selected rotational orientation of the endovascular delivery device the nose cone dilator can be observed by radiographic means during an endovascular procedure to be in that selected rotational orientation. The selected transverse profile can be a notch, protrusion or aperture. The notch or aperture can be filled with a radio-transparent material to provide a sooth outer surface.

Claims

1. An endovascular delivery device comprising a part thereof being formed from a radiopaque material and in use the part being intended to be deployed into a human or animal body, the part being of a selected transverse profile whereby in a selected rotational orientation of the endovascular delivery device the part can be observed within the human or animal body by radiographic means during an endovascular procedure to be in that selected rotational orientation.

2. An endovascular delivery device as in claim 1 wherein the selected profile is transversely offset from the longitudinal centre of the part.

3. An endovascular delivery device as in claim 1 wherein the selected profile is selected from a group comprising a lateral protrusion, a through aperture, a V-shaped notch or a U-shaped notch on the part.

4. An endovascular delivery device as in claim 1 wherein the part is a nose cone dilator and the selected profile comprises a transverse notch in the nose cone dilator.

5. An endovascular delivery device as in claim 4 wherein the notch comprises a V-notch or a U-shaped notch.

6. An endovascular delivery device as in claim 1 wherein the part is formed from a material selected from the group comprising vinyl radiopaque thick wall tubing or urethane radiopaque tubing.

7. An endovascular delivery device as in claim 4 wherein the nose cone dilator comprises a longitudinal groove to receive an indwelling catheter therein and the transverse notch is at the proximal end of the longitudinal groove.

8. An endovascular delivery device as in claim 1 wherein the part is a delivery catheter and the selected profile comprises a transverse notch in the delivery catheter.

9. An endovascular delivery device as in claim 1 wherein the selected transverse profile is a notch or an aperture through the part of the delivery device and the notch or aperture is filed with a radio-transparent material so that the part provides a smooth outer surface for passing through the vasculature but at the same time allowing for radiographic observation of the notch.

10. An endovascular delivery device comprising a delivery catheter, a guide wire catheter extending through and proximally of the delivery catheter, a nose cone dilator at the proximal end of the guide wire catheter and a handle at the distal end of the delivery catheter, at least the nose cone dilator being formed from a radiopaque material and the nose cone dilator being of a selected transverse profile whereby in a selected rotational orientation of the endovascular delivery device the nose cone dilator can be observed by radiographic means during an endovascular procedure to be in that selected rotational orientation.

11. An endovascular delivery device as in claim 10 wherein the selected profile of the nose cone dilator comprises a transverse notch in the nose cone dilator.

12. An endovascular delivery device as in claim 11 wherein the notch comprises a lateral protrusion, a through aperture, a V-shaped notch or a U-shaped notch, the transverse notch being transversely offset from the longitudinal centre of the dilator.

13. An endovascular delivery device as in claim 10 wherein the nose cone dilator comprises a longitudinal groove to receive an indwelling catheter therein and the transverse notch is at the proximal end of the longitudinal groove.

14. An endovascular delivery device as in claim 10 wherein the nose cone dilator is formed from a material selected from the group comprising vinyl radiopaque thick wall dilator tubing or urethane radiopaque tubing.

15. An endovascular delivery device as in claim 10 wherein the selected profile is a notch or a aperture through the part of the delivery device and the notch or aperture is filed with a radio-translucent material so that the part provides a smooth outer surface for passing through the vasculature but at the same time allowing for radiographic observation of the notch.
