In other embodiments of the invention, the endoscope or other visualization means is inserted into the chest cavity through an additional, optional port, wholly independent of the capture instruments and delivery tube. In this case, the endoscope or other visualiztion means need not be transferred from one port to another during the procedure. Regardless of the port the endscope or other visualization means is inserted through, the endoscope or other visualization means permits the medical professional to view the cardiac assist device and various instruments, tethers, anchoring devices and procedures involved in the systems and methods of the invention in an unobtrusive manner.
Of course, where the optional port 303 (FIG. 4) is provided, the endoscope, or other visualizing means, may be initially inserted through the optional port 303. In this case, the endoscope need not be transferred into the port 300 vacated by the removal of the delivery tube 105 from port 300. Rather, removal of the delivery tube 105 from port 300 permits port 300 to be removed as well using conventional port removal techniques. In this embodiment, therefore, viewing of the procedures according to the invention occurs via the endoscope or other visualizing means inserted through optional port 303. The artisan should appreciate that insertion of the endoscope or other visualizing means into the optional port 303 is achieved similarly to the insertion of the endoscope 400 through either of ports 300-302, thus illustration of the insertion of the endocope or other visualizing means through optional port 303 is omitted.
