Patent number: 8870552Abstract: A pump assembly and estimation and control system therefor, the pump adapted for continuous flow pumping of blood. In a particular form, the pump is a centrifugal pump wherein the impeller is entirely sealed within the pump housing and is exclusively hydrodynamically suspended therein against movement in three translational and two rotational degrees of freedom as the impeller rotates within the fluid urged by electromagnetic means external to the pump cavity. Hydrodynamic suspension is assisted by the impeller having deformities therein such as blades with surfaces tapered from the leading edges to the trailing edges of bottom and top surfaces thereof.Type: GrantFiled: August 24, 2012Date of Patent: October 28, 2014Assignee: Thoratec CorporationInventors: Peter Joseph Ayre, Geoffrey Douglas Tansley, Peter Andrew Watterson, John Campbell Woodard

Patent number: 8002691Abstract: A fluid pressure generating means (10) for a heart assist device having blood pumping means. The pressure generating means (10) includes a housing (11), defining an interior volume (18), and having a substantially rigid first housing portion (12), a substantially rigid second housing portion (14), a flexible third housing portion (16) extending between the first (12) and second (14) housing portions and an inlet/outlet port (15) adapted for fluid communication with the blood pumping means. The pressure generating means (10) also includes a fluid filling the housing and a motor (20) disposed within the housing (11) and connected between the first (12) and second (14) housing portions. Actuation of the motor (20) moves the first (12) and second (14) housing portions relative to one another to generate fluid pressure changes at the inlet/outlet port (15). A related heart assist device and method for the treatment of congestive heart failure, myocardial ischemia and like conditions are also disclosed.Type: GrantFiled: October 11, 2007Date of Patent: August 23, 2011Assignee: Sunshine Heart Company Pty Ltd.Inventors: William Suttle Peters, Hans Hansforth Henrichsen, Peter Andrew Watterson
