The present invention includes various embodiments of methods of circulating blood in a mammalian circulatory system, and various blood circulation assemblies adapted to perform such circulation. In one embodiment of the present invention, a blood circulation assembly includes a blood circulation device having an inlet and a discharge; a first cannula including a proximal portion in communication with the inlet, the proximal portion having a wall extending around a first longitudinal axis and having outer and inner faces, said inner face defining a bore, and a distal portion including an outer face tapering distally toward said axis and at least two openings extending from said outer face and merging with one another to form a hollow space within said distal portion, said hollow space communicating with said bore of said proximal portion; and a second cannula including a proximal portion in communication with the discharge, the proximal portion having a wall extending around a first longitudinal axis and having outer and inner faces, said inner face defining a bore, and a distal portion including an outer face tapering distally toward said axis and at least two openings extending from said outer face and merging with one another to form a hollow space within said distal portion, said hollow space communicating with said bore of said proximal portion.

In one embodiment, the present invention includes a connector ring assembly to attach a VAD to a heart. The assembly includes a clamp which can rotate completely about the annular wall in a first state and is fixed relative to the annular wall in a second state. The clamp transitions from the first state to the second state via an actuator. The actuator can be configured with an axis of rotation generally parallel to the opening of the annular wall, thereby allowing manipulation of the actuator through the same surgical accessway as that used to implant the connector ring assembly. At least one embodiment provides a connector flange separately from an annular wall to provide greater access to the connector flange during implantation. The annular wall and clamp are attached to the connector flange after the flange is fixed to the heart.

In one embodiment, the present invention includes a percutaneous skin connector including a base and a cap. The base has a channel extending through it and a plurality of base magnets are positioned around the channel and exposed at a base surface. A skirt which allows tissue ingrowth extends from the base to further secure the base to the patient. The connector also includes a cap with a bore extending through it and a plurality of cap magnets positioned around the bore and exposed at a cap surface. The base magnets and cap magnets attract and align the cap surface to the base surface. The connector further includes a release mechanism adapted to at least partially separate the cap from the base when the cap is rotated relative to the base and out of alignment with the base.
