Published: with international search report (Art. 21(3)) (54) Title: CONVERTIBLE MULTI-STAGE/BI-CAVAL FEMORAL VENOUS CANNULA FIC.5 (57) : A venous drainage cannula, catheter, or other device is in certain embodiments convertible or adjustable for application in cardiac surgery procedures involving cardiopulmonary bypass. Such a convertible cannula device can be modified, for example, for use as both a multi-stage cannula and a bi-caval cannula, so that the same device can be used in multiple different procedures where one or the other cannula type is needed. Such convertible cannula or other device can simplify and reduce a number of parts needed for a bypass procedure, by providing one adjustable and versatile device to serve multiple functions where different cannulae are traditionally required. Various embodiments further provide cannula devices where a variety of different hole or opening arrangements and configurations can be achieved, to adapt to various different procedures.
