Modular systems comprising a cannula (44) and at least one clip-on access po rt (20) adjacent to a distal end of the cannula (44) 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 (20) can be removably attached to a distal region (40) of the cannula (44) 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, vesse l occlusion, atherectomy, and endoscopic devices. Methods of using the system for vessel cannulation are also disclosed herein. |
