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

providing a cannula having a lumen that communicates distally with a first port;

attaching a second port to a distal end of the cannula radially adjacent the first port;

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

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

deploying the medical device.

2. The method of claim 1, further comprising the steps of:

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

deploying the second medical device.

3. The method of claim 2, 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.

4. The method of claim 1, 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.

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

6. The method of claim 5, wherein the artery is the aorta.

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

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

9. The method of claim 1, wherein the blood vessel is the inferior vena cava.

10. The method of claim 1, further comprising the step of infusing blood through the lumen of the cannula.

11. The method of claim 10, wherein the port comprises an arcuate brace at its distal end, said arcuate brace shaped to receive a distal portion of the cannula.

12. The method of claim 1, further comprising the steps of:

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

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

13. The method of claim 1, further comprising the step of inserting an obturator through the second port.

14. The method of claim 13, wherein the obturator includes a porous plug.

15. The method of claim 1, wherein the step of attaching a second port includes engaging a clip.

16. The method of claim 1, wherein the second port is removable.
