摘要： An improved implantable infusion device for delivering precisely regulated doses of fluid into the body of a patient. The device utilizes a resilient non-compliant pump bellows (13) that is directly coupled by a gear train (15, 17, 19, 21) to a motor (23). The bellows (13) is biased toward the expanded position and this factor, combined with the mechanical inertia of the gear train (15, 17, 19, 21) substantially eliminates the danger of an overdose of infusate being released into the patient.

摘要： A biventricular circulatory support system for a human patient. A mechanical first pump (49) for assuming at least a part of the pumping load of the patient's left ventricle is implanted in the patient. A second pump (55) for assuming at least a part of the pumping load of the patient's right ventricle is also implanted. The second pump (55) includes a surgically prepared skeletal muscle pedicle (33) with nerves and blood supply substantially intact. The muscle pedicle (33) is applied directly to the right ventricle (55) or is applied to an artificial pump sac (55). Electrical signals are applied to the first and second pumps (49), (55) as appropriate to cause pumping action in a predetermined relationship.

摘要： An actuator (12) and sac (14) for use in a pump having a pump chamber whose contents are expelled by movement of a pair of pusher plates (30, 32) toward one another. The actuator includes opposed solenoid armatures (50, 52) which are operable for movement between open and closed positions. The armatures are each operatively connected to an associated pusher plate by a main spring (90, 92) which is attached at one end to the back end of the armature, extends through a front-to-back slot in an armature core, and is connected at its opposite end to the pusher plate. A pair of preload springs (114, 116) carried on each armature and disposed on either side of the associated main spring acts to hold the main spring in a prestressed condition prior to solenoid actuation. With closure of the armatures, and with the sac still in an expanded condition, the main springs are disengaged from the associated preload spring and placed in a more stressed, more planar configuration, with the increased stress in each main spring being relieved by movement of the pusher plates toward one another. The sac has an annular side wall which is held in a rigid condition, and a pair of opposed circular walls, each joined to the annular side wall through a flexible annular wall portion. A circular pusher plate acting against each circular wall has an initial deflection position at which the associated flexible wall portion in the sac takes the form of a circumferentially uniform roll having an outwardly convex, bulged cross sectional curvature. The rolls in the sac maintain their circumferentially uniform, bulge-like character as the pusher plates are moved toward inwardly moved positions.

摘要： A heart-assist system and a method for operating same in which a pump (1) is connected to a ventricle (3) to receive output therefrom. An actuator comprising plates (15, 17), springs (27, 33), frame (61) and solenoid armatures (63, 65) operates to cause the pump to conduct a fill cycle in which it receives output from the ventricle (3) to which it is connected, and to conduct an eject cycle in which the contents of the pump (1) are expelled. The time of initiation of at least one of the fill cycle and the eject cycle is varied in relation to systole of the ventricle to which the pump is connected to thereby vary the loading of the ventricle. Several techniques for detecting termination of systole are described including a compliant stop on the pump.

摘要： A biventricular circulatory support system wherein a first pump (10) supports left ventricular circulation (systemic) and a second pump (110) for supporting right ventricular circulation (pulmonary). Both pumps are implanted in a patient, and each pump is enclosed in a sac (11, 111) defining a pumping chamber (13, 113).

摘要： Novel process for producing covalently bonded laminated structures composed of polyurethane elastomer and vulcanized rubber layers. As the joining means for covalently bonding the polyurethane elastomer and vulcanizable rubber laminates the process utilizes novel grafted polyurethane joining compositions comprised of polyurethane elastomer, a polyisocyanate, and a hydroxyl containing polybutadiene difunctional linker molecule. In practicing the process of the invention, the grafted polyurethane joining composition is first prepared by means that create covalent chemical bonds between the polyurethane elastomer and a first functional (NCO) group on the polyisocyanate, as well as between a hydroxyl on the polybutadiene difunctional linker molecule and a second functional (NCO) group on the polyisocyanate. This novel grafted polyurethane composition is then used to bond layers of polyurethane elastomer to layers of vulcanizable rubber. In constructing a laminated product, the grafted polyurethane joining composition is interposed between the polyurethane elastomer and vulcanizable rubber layers. The resulting assembly is then heated at a temperature sufficient to allow formation of covalent bonds.
