Abstract: Materials and methods related to blood pump systems are described. These can be used in patients to, for example, monitor arterial pressure, measure blood flow, maintain left ventricular pressure within a particular range, avoid left ventricular collapse, prevent fusion of the aortic valve in a subject having a blood pump, and provide a means to wean a patient from a blood pump.

Abstract: Connectors and related methods for fluidly coupling a blood pump with an aorta facilitate implantation of the blood pump. A method of fluidly coupling a blood pump with an aorta includes positioning a connector device defining a passageway extending between a proximal opening and a distal opening. The connector device includes a support member surrounding the distal opening. The support member is interfaced with a wall of the aorta so that the distal opening is at a desired location of an inlet opening in the aorta. The support member is attached to the aorta around the distal opening so as to form a fluid seal and stabilize the connector device. A slit is incised in the wall of the aorta to form the inlet opening in the aorta. A proximal opening of the tubular connector is fluidly coupled with an outflow graft tube of the blood pump.

Abstract: A blood pump system includes a pump housing and an impeller for rotating in a pump chamber within the housing. The impeller has a first side and a second side opposite the first side. The system includes a stator having drive coils for applying a torque to the impeller and at least one bearing mechanism for suspending the impeller within the pump chamber. The system includes a position control mechanism for moving the impeller in an axial direction within the pump chamber to adjust a size of a first gap and a size of a second gap, thereby controlling a washout rate at each of the first gap and the second gap. The first gap is defined by a distance between the first side and the housing and the second gap is defined by a distance between the second side and the pump housing.

Abstract: An implantable wireless sensor is provided for determining a pressure of a lumen in a body. The sensor comprises a sensor body comprising a plurality of substrates, at least a portion of the substrates comprising a first dielectric material. An LC resonant circuit is contained with the sensor body. A capacitance of the LC resonant circuit is configured to vary in response to changes in pressure in the lumen. A first anchoring element is coupled to a proximal end of the sensor body and a second anchoring element is coupled to a distal end of the sensor body. The first and second anchoring elements are configured to lodge the sensor body within the lumen. A second dielectric material, different than the first dielectric material, is provided over at least a portion of at least one of the plurality of substrates.

Abstract: A catheter system includes a catheter, a recovery sheath, and an outer sheath assembly. The catheter includes an elongate body having an expandable medical device coupled with a distal end thereof. The recovery sheath is disposed around a proximal section of the catheter body, and is sized and shaped to receive the expandable medical device therein. The recovery sheath is axially movable relative to the catheter body. The outer sheath assembly includes an outer sheath disposed over the catheter body. The outer sheath includes an elongate body that extends from a proximal end to a distal end, where the proximal end of the outer sheath body is positioned distally of the recovery sheath. The outer sheath includes a retention section sized and shaped to receive the expandable medical device therein and constrain the expandable medical device in a stored configuration. The outer sheath is removable from the catheter body.
