An implantable heart assist system includes a compressible pumping chamber including an inlet conduit to be placed in fluid connection with the descending thoracic aorta and an outlet conduit to be placed in fluid connection with the thoracic aorta; and a pump system comprising a first rigid member, a second rigid member positioned so that at least a portion of the pumping chamber may be positioned between the first and second rigid members, a drive system configured to cause the second rigid member to move toward or away from the first rigid member, and a controller in operative connection with the drive system and controlling the drive system, wherein movement of the second rigid member toward the first rigid member results in compresses the pumping chamber and movement of the second rigid member away from the first rigid member expands the pumping chamber.

Thoracic aorta ventricular assist system

An implantable heart assist system, includes a pumping chamber formed of a flexible material and being adapted to be placed in fluid connection with the aorta and a pump system comprising a first rigid member and a spaced apart second rigid member so that at least a portion of the pumping chamber may be positioned therebetween, a drive system comprising a motor. The motor is adapted to cause the second rigid member to move toward the first rigid member to compress the pumping chamber or away from the first rigid member to expand the pumping chamber. A controller is in operative connection with the drive system and controlling the motor.

A system for assisting blood flow in a patient includes an implantable pump system for assisting in blood flow from the heart and an implantable control system for communicative connection with the implantable pump system. The control system includes a pacemaker system that is operative to control heart rate and the pump system interdependently to achieve a determined level of blood flow assist. The control system is adapted to increase the heart rate of the patient to above a normal heart rate for the patient under the present conditions of the patient via the pacemaker while controlling the pump system to achieve the determined level of blood flow assist based upon the increased heart rate and a level of assist provided by the pump system.

Control of blood flow assist systems

In one aspect, an implantable pump system for assisting blood flow in a patient includes a blood flow path comprising a flexible conduit, at least one valve in fluid connection with the flexible conduit, a drive system in operative connection with the valve to move the valve in a reciprocating manner, an implantable control system and at least one sensor in communicative connection with the control system. The sensor is adapted to measure at least one property of blood. The control system is adapted to control movement of the valve on the basis of data regarding position of the valve with respect to time or a derivative thereof (that is, position, velocity, acceleration or a derivative thereof) in combination with data of the measured at least one property of blood from the sensor.

An implant for osteosynthesis used in the stabilization of fractured bone of the mandible. The plate consists of apertures through which the plate is secured to bone using surgical screws. The apertures are connected by (a) two lateral bar sections running approximately parallel to the long axis of the mandible and (b) two cross bar sections intersecting each other near the centroid of the plate and at acute angles to the lateral bar sections. The plate design can be modified to accommodate patient anatomy depending on the type of bone it is designed to stabilize. Design and size parameters of the fixation plate can be customized to each individual patient using a customization software application to determine the least invasive fixation plate that will provide adequate functioning in stabilizing the bone fracture to a degree that will allow safe bone healing. The invention includes a method of design of osteosynthesis plates using shape optimization for different types and locations of fractures.
