Inflow / outflow cannula anchors

A cannula comprising:

• a conduit having an exterior surface and an interior surface, a proximal end and a distal end;
• an anchoring structure attached to the conduit adjacent an end of the conduit, the anchoring structure including:
• a first anchor portion having a plurality of first contact features and a first stent element extending along the exterior surface of the conduit toward the distal end of the conduit, and
• a second anchor portion having a plurality of second contact features and a second stent element extending along the exterior surface of the conduit toward the proximal end of the conduit, the first stent element being configured to facilitate folding of the first anchor portion toward the exterior surface of the conduit and adjacent the second stent element and the second stent element is configured to facilitate folding of the second anchor portion toward the exterior surface of the conduit and adjacent the first stent element in a delivery configuration.

A cannula comprising:

• a conduit having an exterior surface and an interior surface;
• an anchoring structure arranged adjacent an end of the conduit configured to engage with tissue and anchor the conduit, the anchoring structure including:
• a first anchor portion having a plurality of first contact features extending longitudinally outward relative to the exterior surface of the conduit and a stent portion extending along the exterior surface of the conduit to facilitate folding of the first anchor portion toward the exterior surface of the conduit and in a first direction in a delivery configuration, and
• a second anchor portion having a plurality of second contact features extending longitudinally outward relative to the exterior surface of the conduit and a stent portion extending along the exterior surface of the conduit to facilitate folding of the second anchor portion toward the exterior surface of the conduit and in a second direction opposite the first direction in the delivery configuration.
