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;
a clip to hold a removably attached port adjacent the distal end of the cannula, said port having a proximal end adapted to receive a medical device, a distal end, and a lumen therebetween;
a medical device inserted through the port and passing through cardiac tissue into a lumen or body cavity.

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.

20. A method for cannulation of a patient'"'"'s blood vessel or cardiac tissue, comprising the steps of:
-
providing a cannula having a lumen;
attaching a removable port adjacent a distal end of the cannula by operating a clip;
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 vessel or cardiac tissue; and
deploying the medical device. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34)
inserting a second medical device through the port into the vessel or cardiac tissue; and
deploying the second medical device.

-
22. The method of claim 20, wherein the clip comprises one or more member that extend between the cannula and the port.
-
23. The method of claim 20, 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 stent-graft, a shunt, a perfusion catheter, and endoscopic devices.
