TRANSSEPTAL CANNULA, TIP, DELIVERY SYSTEM, AND METHOD

摘要

A transseptal cannula assembly (224) for directing blood from the heart (104) of a patient and a minimally invasive method of implanting the same. The transseptal cannula assembly (224) includes a flexible cannula body (226) having proximal and distal portions with a lumen there between, a tip (228) coupled to the distal portion of the flexible cannula body (226), and first and second anchors (230, 232) coupled to the tip (228). The anchors (230, 232) can be configured to be deployed from a contracted state to an expanded state and are configured to engage opposite sides of the heart tissue (102) when in the expanded state. The anchors (230, 232) resist movement of the cannula assembly (224) along a lengthwise central axis of the flexible cannula body (226).
