Abstract:
1. An endoscopic cannulation assembly for remotely cannulating a heart at a cannulation site, the cannulation assembly comprising: a trocar; an endoscopic shaft for guiding functional components of the cannulation assembly to the cannulation site, the endoscopic shaft defining a distal end, a proximal end, an outside surface between the distal end and the proximal end, and a lumen; a fluid stasis assembly concentrically and slidably mounted about the outside surface of the endoscopic shaft, the fluid stasis assembly configured to slide with respect to the endoscopic shaft, the fluid stasis assembly comprises an occlusive device, wherein the occlusive device comprises at least one de-airing port configured to emit fluid to help remove bubbles and debris; a coring assembly concentrically and slidably mounted about the outside surface of the endoscopic shaft, the fluid stasis assembly and the coring assembly each being mounted adjacent the outside surface of the endoscopic shaft, the coring assembly being adapted to core the heart, wherein the fluid stasis assembly is capable of being deployed prior to or concurrent with operation of the coring assembly; a core retainer positioned on the coring assembly or the endoscopic shaft for retaining the core that is cut from the heart; a guard situated between the occlusive device and the coring assembly to protect the occlusive device from contact with the coring assembly; and a cannula sized and configured to insert into the hole formed by the coring assembly to provide a seal to enable de-airing.
