In one embodiment, the present invention includes a percutaneous skin connector 1 including a base 3 and a cap 2. The base 3 has a channel 31 extending through it and a plurality of base magnets 24, 29 are positioned around the channel 31 and exposed at a base surface 30. A skirt 21 which allows tissue ingrowth extends from the base 3 to further secure the base 3 to the patient. The connector 1 also includes a cap 2 with a bore 61 extending through it and a plurality of cap magnets 47, 48 positioned around the bore 61 and exposed at a cap surface 42. The base magnets 24, 29 and cap magnets 47, 48 attract and align the cap surface 42 to the base surface 30. The connector 1 further includes a release mechanism adapted to at least partially separate the cap 2 from the base 3 when the cap 2 is rotated relative to the base 3 and out of alignment with the base 3.

A method for monitoring a charge of a battery in a device, comprising providing a low power processor having a wake state and a dormant state, the low power processor configured to periodically change from the dormant state to the wake state. The method further comprises periodically enabling a battery monitor circuit to determine the charge of the battery, the low power processor enabling the battery monitor circuit when the low power processor is in the wake state. The battery monitor circuit has a default safe state in which a digital processor enables the battery monitor circuit and a normal operating state in which the low power processor periodically enables the battery monitor circuit, the battery monitor circuit switching from the default safe state to the normal operating state when the low power processor is detected. The digital processor is different than the low power processor.


An apparatus includes a tubular member defining a lumen and a channel, and a support member. The tubular member has a connection portion configured to be coupled to an organ wall. An outer edge of the connection portion is configured to contact a first portion of an inner surface of the wall when the connection portion is in an expanded configuration such that an interior volume of the organ is in fluid communication with the lumen. The support member is movably disposed within the channel and is configured to minimize movement of the wall relative to the tubular member. An end portion of the support member is disposed within the channel when the support member is in a first configuration. The end portion of the support member configured to contact a second portion of the inner surface of the wall when the support member is in a second configuration.

One aspect of an intravascular ventricular assist device is an implantable blood pump where the pump includes a housing defining a bore having an axis, one or more rotors disposed within the bore, each rotor including a plurality of magnetic poles, and one or more stators surrounding the bore for providing a magnetic field within the bore to induce rotation of each of the one or more rotors. Another aspect of the invention includes methods of providing cardiac assistance to a mammalian subject as, for example, a human. Further aspects of the invention include rotor bodies having helical channels formed longitudinally along the length of the body of the rotor where each helical channel is formed between peripheral support surface areas facing radially outwardly and extending generally in circumferential directions around the rotational axis of the rotor.

In one embodiment, the present invention includes a connector ring assembly 220 to attach a VAD to a heart. The assembly 220 includes a clamp 224 which can rotate completely about the annular wall 222 in a first state and is fixed relative to the annular wall 222 in a second state. The clamp 224 transitions from the first state to the second state via an actuator 234. The actuator 234 can be configured with an axis of rotation 138 generally parallel to the opening 50 of the annular wall 222, thereby allowing manipulation of the actuator 234 through the same surgical accessway as that used to implant the connector ring assembly 220. At least one embodiment provides a connector flange 172 separately from an annular wall 122 to provide greater access to the connector flange 172 during implantation. The annular wall 122 and clamp 124 are attached to the connector flange 172 after the flange is fixed to the heart.
