Abstract

The invention provides for methods of delivering compositions to an individual via the vasculature, and provides for a device that can be used to deliver compositions to an individual via the vasculature.

Claims

1. A device for occluding blood flow in a vessel, comprising:

a catheter body, the catheter body having a proximal portion and a distal portion, wherein the proximal and distal portions define a longitudinal axis, wherein the catheter body has an inner lumen; and

an occlusion member, wherein the occlusion member comprises a bore through which the catheter body is engaged, wherein the occlusion member comprises a distal end and a proximal end.

2. The device of claim 1, further comprising:

an outer sheath, wherein the outer sheath is slidably movable along the longitudinal axis of the catheter body.

3. The device of claim 1, further comprising:

a catheter body sheath, wherein the catheter body sheath is slidably movable along the longitudinal axis of the catheter body, wherein the catheter body sheath is located between the catheter body and the outer sheath, wherein the distal end of the catheter body sheath is engaged with the proximal end of the occlusion member.

4. The device of claim 3, wherein the catheter body sheath further comprises a catheter body sheath flange, wherein the flange is engaged with the proximal end of the occlusion member.

5. The device of claim 1, wherein the occlusion member is cylindrically-shaped or conically-shaped.

6. The device of claim 1, wherein the occlusion member is silicone or foam.

7. The device of claim 1, wherein the occlusion member is biodegradable.

8. The device of claim 1, wherein the occlusion member is impregnated with a bioactive substance.

9. The device of claim 8, wherein the bioactive substance is selected from the group consisting of one or more chemotherapeutic agents, one or more growth factors, or a nucleic acid encoding a growth factor.

10. The device of claim 1, wherein the device is disposable.

11. The device of claim 1, wherein the device is sterilizable.

12. The device of claim 1, wherein the inner lumen of the catheter body comprises a composition selected from the group consisting of stem cells, one or more growth factors, one or more chemotherapeutic agents, a nucleic acid encoding a growth factor, and an anti-inflammatory compound.

13. A method of delivering a composition to a biological target in an individual, comprising:

inserting and advancing the distal portion of the catheter body of the device of claim 1 into a vessel in the vasculature of the individual such that the distal portion of the device is positioned at a delivery site in the vessel;

retracting the outer sheath such that the occlusion member substantially occludes blood flow through the vessel;

delivering the composition to the delivery site via the inner lumen of the catheter body; and

removing the device from the vessel.

14. The method of claim 13, further comprising:

discharging the occlusion member from the distal portion of the catheter body, wherein the discharging is prior to the removing step.

15. The method of claim 13, wherein the occlusion member is foam, silicone, or biodegradable.

16. The method of claim 13, wherein the occlusion member is cylindrically-shaped or conically-shaped.

17. The method of claim 13, wherein the vessel is a vein.

18. The method of claim 13, wherein the composition is selected from the group consisting of stem cells, one or more growth factors, one or more chemotherapeutic agents, a nucleic acid encoding a growth factor, and an anti-inflammatory compound.

19. The method of claim 18, wherein the stem cells comprise a heterologous nucleic acid encoding VEGF.

20. The method of claim 13, wherein the biological target is selected from the group consisting of heart, liver, pancreas, kidney, brain, uterus, ovaries, prostate, testicles, intestines, eyes, vocal chord, and solid cancer tumor.

21. The method of claim 14, wherein the bore in the occlusion member closes following discharging of the occlusion member.

22. The method of claim 13, wherein the delivery site in the vessel is distal to the occlusion member.
