Publication number: 20210085850Abstract: A ventricular assist device for use in a human recipient includes a housing within which a series pair of turbine pump segments and at least one set of deswirlers are operative. The series pair of turbine pump segments provides a redundancy in turn enhances the safety factor provided by the ventricular assist device. A controller is powered by a rechargeable battery and is operative to apply appropriate drive signals to the motor drives of the turbine pump segments. The battery may be implanted along with the controller to avoid the need for any external connections to the ventricular assist device. An inductively coupled battery charger for use outside the recipient's body is positioned proximate the battery charger to provide inductively coupled charging for use in driving the ventricular assist device.Type: ApplicationFiled: December 3, 2020Publication date: March 25, 2021Applicant: California Cardiac Solutions, Inc.Inventors: Peter DeSilva, Steve Smith

Patent number: 10722626Abstract: An artificial heart for use in a human recipient includes a housing within which a quartet of turbine pump segments are operative. The quartet of turbine pump segments is configured to provide a pair of redundant input and output turbine pump segment pairs each input and output pair being coupled by a curved passage providing a redundancy which, in turn, enhances the safety factor provided by the artificial heart. Each turbine pump segment includes an impeller forwarded for rotation and having a plurality of impeller blades together with a static deswirler positioned within the impeller output flow to reduce the swirling turbulence of the blood flow induced by the rotating impeller.Type: GrantFiled: September 14, 2018Date of Patent: July 28, 2020Inventors: Peter DeSilva, Steve Smith

Publication number: 20200147282Abstract: An artificial heart for use in a human recipient includes a housing within which a trio of turbine pump segments are operative. Two of the turbine pumps form a series connected pair for redundancy. The redundancy enhances the safety factor provided by the artificial heart. A controller is powered by a rechargeable battery and is operative to apply appropriate drive signals to the motor drives of the turbine pump segments. The battery may be implanted along with the controller to avoid the need for any external connections to the artificial heart. An inductively coupled battery charger for use outside the recipient's body is positioned proximate the battery charger to provide inductively coupled charging for use in driving the artificial heart.Type: ApplicationFiled: October 29, 2019Publication date: May 14, 2020Inventors: Peter DeSilva, Steve Smith
