Abstract

Modular systems comprising a cannula and at least one clip-on access port adjacent to a distal end of the cannula to provide insertion of one or more therapeutic or diagnostic devices into a vessel or cardiac tissue through a single incision site. The access port can be removably attached to a distal region of the cannula in a fixed orientation or in any desired orientation. The devices can be operated in combination or independently. The systems can be employed to provide multiple therapies, including blood perfusion, filtration, aspiration, vessel occlusion, atherectomy, and endoscopic devices. Methods of using the system for vessel cannulation are also disclosed herein.

Claims

1. A cannula for cardiopulmonary bypass, comprising:

an elongate tubular member having a proximal end, a distal end, and a lumen extending from the proximal to the distal end; and

a port adjacent the distal end of the elongate tubular member, said port having a proximal end adapted to receive a medical device, a distal end, a lumen therebetween, and an arcuate brace extending from the distal end, wherein said arcuate brace is shaped to receive a distal portion of the elongate tubular member.

2. The cannula of claim 1, further comprising a second port adjacent the first port at the distal end of the elongate tubular member, said second port having a proximal end adapted to receive a medical device, a distal end, and a lumen therebetween.

3. The cannula of claim 1, wherein the medical device is selected from the group consisting of a blood filter, a balloon occluder, a pressure monitor, an endoscopic device, an atherectomy device, an aspirator, a drug delivery catheter, an occlusion catheter, an angioplasty catheter, as valvuloplasty catheter, an electrode catheter, an internal vessel segregating or isolating dam, a stent, a graft, a stent-graft, a shunt, a perfusion catheter, and a blood-sampling device.

4. The cannula of claim 3, wherein the blood-sampling device obtains blood for analyzing activated clotting time.

5. The cannula of claim 1, further comprising a second port adjacent the distal end of the elongate tubular member and adjacent the first port, wherein the ports and the distal end of the elongate tubular member are arranged at the vertices of a triangle.

6. The cannula of claim 1, further comprising a second port adjacent the distal end of the elongate tubular member and adjacent the first port, wherein the ports and the distal end of the elongate tubular member are arranged substantially in a line.

7. The cannula of claim 1, wherein the proximal end of the elongate tubular member is adapted for attachment to a bypass oxygenator machine.

8. The cannula of claim 1, wherein the elongate tubular member is flexible.

9. The cannula of claims 5 or 6, wherein the first and the second ports further include hemostatic valves in their lumens.

10. The cannula of claim 1, wherein the elongate tubular member further comprises a suture flange.

11. The method for cannulation of a patient'"'"'s blood vessel or cardiac tissue, comprising the steps of:

providing a cannula having a lumen;

attaching a port adjacent a distal end of the cannula;

inserting the distal end of the cannula and adjacent port into a blood vessel or cardiac tissue;

inserting a medical device through the port into the blood vessel or cardiac tissue;

and

deploying the medical device.

12. The method of claim 11, further comprising the steps of:

inserting a second medical device through the port into the vessel or cardiac tissue; and

deploying the second medical device.

13. The method of claim 11, wherein the first medical device is selected from the group consisting of a blood filter, a balloon occluder, a pressure monitor, an endoscopic device, an atherectomy device, an aspirator, a drug delivery catheter, an occlusion catheter, an angioplasty catheter, a valvuloplasty catheter, an electrode catheter, an internal vessel segregating or isolating dam, a stent, a graft, a stent-graft, a shunt, a perfusion catheter, and a blood-sampling device.

14. The method of claim 11, wherein the blood vessel is an artery.

15. The method of claim 14, wherein the artery is the aorta.

16. The method of claim 11, wherein the cardiac tissue is the right atrium.

17. The method of claim 11, wherein the blood vessel is a vein.

18. The method of claim 11, wherein the blood vessel is the inferior vena cava.

19. The method of claim 11, further comprising the step of infusing blood through the lumen of the cannula.

20. The method of claim 12, wherein the second medical device is selected from the group consisting of a blood filter, a balloon occluder, a pressure monitor, an endoscopic device, an atherectomy device, an aspirator, a drug delivery catheter, an occlusion catheter, an angioplasty catheter, a valvuloplasty catheter, an electrode catheter, an internal vessel segregating or isolating dam, a stent, a graft, a stent-graft, a shunt, a perfusion catheter, and a blood-sampling device.

21. The method of claim 11, further comprising the steps of:

attaching a second port adjacent the distal end of the cannula; and

inserting a second medical device through the second port into the blood vessel or cardiac tissue.

22. The method of claim 11, further comprising the step of inserting an obturator through the port.

23. The method of claim 22, wherein the obturator includes a porous plug.

24. The method of claim 11, wherein the step of attaching a port includes engaging a clip.

25. The method of claim 11, wherein the port is removable.

26. The method of claim 19, wherein the port comprises an arcuate brace at its distal end, said archuate brace shaped to receive a distal portion of the cannula.
