Abstract

Medical device delivery systems, components, and methods are provided.

Claims

1. A method for flushing an implantable medical endoprosthesis delivery system, the method comprising:

providing an implantable medical endoprosthesis delivery system comprising;

an inner member having a first lumen defined therein;

an outer member disposed about the inner member;

wherein a second lumen is defined between the inner member and the outer member,

a hub having a bore formed therein that is in fluid communication with the first lumen and the second lumen,

wherein a proximal end of the inner member is attached to a first portion of the bore,

wherein a proximal end of the outer member is attached to a second portion of the bore, and

wherein the first portion of the bore has a first inner diameter, wherein the second portion of the bore has a second inner diameter, and wherein the first inner diameter is smaller than the second inner diameter;

attaching a fluid introduction device to the hub; and

introducing a fluid into the hub with the fluid introduction device so as to simultaneously flush the first lumen and the second lumen.

2. The method of claim 1, wherein the bore defines a first fluid pathway in fluid communication with the first lumen and a second fluid pathway in fluid communication with the second lumen.

3. The method of claim 1, wherein a counterbore flush slot is defined between the inner member and the outer member.

4. The method of claim 3, wherein the counterbore flush slot is in fluid communication with the second lumen.

5. The method of claim 1, wherein the hub defines a single flush slot that is in fluid communication with the first lumen and the second lumen.

6. The method of claim 1, wherein the hub defines a plurality of flush slots.

7. The method of claim 6, wherein at least some of the flush slots are arc-shaped.

8. The method of claim 1, wherein a collar is attached to the inner member and to the hub.

9. The method of claim 1, further comprising disposing a flow restrictor adjacent the first lumen.

10. The method of claim 9, wherein the flow restrictor is removable from the implantable medical endoprosthesis delivery system.

11. The method of claim 9, wherein the flow restrictor comprises a pin that is inserted into the first lumen.

12. A method for flushing an implantable medical endoprosthesis delivery system, the method comprising:

providing an implantable medical endoprosthesis delivery system comprising;

an inner member having a first lumen defined therein;

an outer member disposed about the inner member;

wherein a second lumen is defined between the inner member and the outer member,

a hub having a bore formed therein, the bore defining a first fluid pathway in fluid communication with the first lumen and a second fluid pathway in fluid communication with the second lumen,

wherein the inner member is attached to a first portion of the bore,

wherein the outer member is attached to a second portion of the bore, and

attaching a fluid introduction device to the hub; and

introducing a fluid into the bore of the hub with the fluid introduction device so as to simultaneously flush the first lumen and the second lumen by passing the fluid along both the first fluid pathway and the second fluid pathway.

13. The method of claim 12, wherein the first portion of the bore has a first inner diameter, wherein the second portion of the bore has a second inner diameter, and wherein the first inner diameter is smaller than the second inner diameter.

14. The method of claim 12, wherein a counterbore flush slot is defined between the inner member and the outer member.

15. The method of claim 12, wherein the hub defines a single flush slot that is in fluid communication with the first lumen and the second lumen.

16. The method of claim 12, wherein the hub defines a plurality of flush slots.

17. The method of claim 12, wherein a collar is attached to the inner member and to the hub.

18. The method of claim 12, further comprising disposing a flow restrictor adjacent the first lumen.

19. A method for simultaneously flushing multiple lumens, the method comprising:

introducing fluid into a hub having a proximal end of an inner member and a proximal end of an outer member attached thereto, the hub being in fluid communication with a first lumen and a second lumen, the first lumen being disposed within the inner member, the second lumen being disposed between the inner member and the outer member, the outer member at least partially surrounding the inner member; and

pressurizing the fluid to introduce the fluid into the first and second lumens to simultaneously flush the first and second lumens.

20. The method of claim 19, further comprising attaching a flow restrictor to the hub.
