Abstract

Modular systems comprising a cannula and at least one access port adjacent to a distal end of the cannula provide insertion of one or more therapeutic or diagnostic devices into a vessel or cardiac tissue through a single incision site. Other embodiments include a vessel introducer or multi-port introducer. 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 method for cannulation of a patient'"'"'s blood vessel or cardiac tissue, comprising the steps of:

making an incision on the aortic arch;

providing an arterial return cannula having an arterial return lumen and a first port and a second port adjacent a distal end;

inserting the distal end of the cannula through the incision into a vessel or cardiac tissue;

infusing oxygenated blood through the arterial return lumen;

inserting a first medical device through the first port into the vessel or cardiac tissue such that the first medical device extends beyond the first port;

inserting a second medical device through the second port into the vessel or cardiac tissue such that the second medical device extends beyond the second port;

deploying the first medical device; and

deploying the second medical device.

2. The method of claim 1, wherein the first medical device is selected from the group consisting of a blood filter, an occlusion catheter, an aspirator, an angioplasty catheter, a valvuloplasty catheter, an electrode catheter, internal vessel segregating or isolating dams, an endoscopic camera, a pressure monitor, a stent, a graft, a shunt, a perfusion catheter, and endoscopic devices.

3. The method of claim 1, wherein the vessel is an artery.

4. The method of claim 1, wherein the artery is the aorta.

5. The method of claim 1, wherein the cardiac tissue is the right atrium.

6. The method of claim 1, wherein the vessel is a vein.

7. The method of claim 6, wherein the vein is the inferior vena cava.

8. The method of claim 1, wherein the second medical device is selected from the group consisting of a blood filter, an occlusion catheter, an aspirator, an angioplasty catheter, a valvuloplasty catheter, an electrode catheter, internal vessel segregating or isolating dams, an endoscopic camera, a pressure monitor, a stent, a graft, a shunt, a perfusion catheter, and endoscopic devices.

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

providing an arterial return cannula having an arterial return lumen and a first port and a second port adjacent a distal end;

inserting the distal end of the cannula into a vessel or cardiac tissue;

infusing oxygenated blood through the arterial return lumen;

inserting a first medical device through the first port into the vessel or cardiac tissue such that the first medical device extends beyond the first port;

inserting a second medical device through the second port into the vessel or cardiac tissue such that the second medical device extends beyond the second port;

deploying the first medical device; and

deploying the second medical device.

10. The method of claim 9, wherein the first and medical device are selected from the group consisting of a blood filter, an occlusion catheter, an aspirator, an angioplasty catheter, a valvuloplasty catheter, an electrode catheter, internal vessel segregating or isolating dams, an endoscopic camera, a pressure monitor, a stent, a graft, a shunt, a perfusion catheter, and endoscopic devices.

11. The method of claim 9, wherein the vessel is an artery.

12. The method of claim 11, wherein the artery is the aorta.

13. The method of claim 9, wherein the cardiac tissue is the right atrium.

14. The method of claim 9, wherein the vessel is a vein.

15. The method of claim 14, wherein the vein is the inferior vena cava.
