Non-Invasive Diagnostics For Ventrical Assist Device

US Patent:
2013004, Feb 21, 2013
Filed:
Aug 15, 2011
Appl. No.:
13/209814
Inventors:
Alexander Medvedev - Ann Arbor MI, US
Muhammad K. Sami - Ypsilanti MI, US
Masamichi Yanai - Ann Arbor MI, US
Assignee:
TERUMO KABUSHIKI KAISHA - Tokyo
International Classification:
A61M 1/10
US Classification:
600 16
Abstract:
A circulatory assist system has a pump with a motor coupled to rotate the pump at a selectable speed. A controller drives the motor at a target speed and collects blood flow measurements during operation of the pump. An impaired flow condition is identified when a plurality of successive blood flow measurements are between an expected minimum flow and a low flow threshold, such that the low flow would necessitate issuing an alert. During the impaired flow condition, it is detected whether an inflow obstruction exists by determining whether a reduction in speed of the pump is correlated with a predetermined increase in the blood flow measurements. If the inflow obstruction is detected, then the speed of the pump is further reduced to further increase the blood flow measurements.

Pressure/Flow Characteristic Modification Of A Centrifugal Pump In A Ventricular Assist Device

US Patent:
2021011, Apr 22, 2021
Filed:
Dec 28, 2020
Appl. No.:
17/135425
Inventors:
- Pleasanton CA, US
Muhammad Sami - Ypsilanti MI, US
Assignee:
TC1 LLC - Pleasanton CA
International Classification:
A61M 60/50
F04D 13/06
F04D 15/00
F04D 29/22
A61M 60/205
A61M 60/148
Abstract:
A ventricular assist device is disclosed. The ventricular assist device may include a centrifugal pump and a controller. The controller may be configured to cause the centrifugal pump to operate at a first speed above a predetermined flow rate. The controller may also be configured to cause the centrifugal pump to operate at a second speed below the predetermined flow rate, wherein the predetermined flowrate is indicative of a crossover point between systole and diastole phases of a person's cardiac cycle.

Blood Pump And Method Of Suction Detection

US Patent:
2016005, Mar 3, 2016
Filed:
Aug 25, 2015
Appl. No.:
14/834757
Inventors:
- Pleasanton CA, US
J. Bradford Rainier - Chelsea MI, US
Muhammad K. Sami - Ypsilanti MI, US
International Classification:
A61M 1/10
Abstract:
A system and method for detecting and mitigating a suction condition are disclosed. The method may include estimating a flow waveform of the pump, identifying pulses in the flow waveform, determining a negative flow based on a valid identification of a pulse, and evaluating a characteristic of the pulse for an existence of a suction condition. In various embodiments, a suction marker is located based on a minimum in a diastolic phase, and the suction marker location is used to identify a probability of a suction condition. A speed of the pump may be adjusted to mitigate the suction condition. A system and method for estimating flow is further disclosed. The method may include interpolating data sets defining pump power to flow for various pump speed values.

Blood Pump And Method Of Suction Detection

US Patent:
2016005, Mar 3, 2016
Filed:
Aug 25, 2015
Appl. No.:
14/834771
Inventors:
- Pleasanton CA, US
J. Bradford Rainier - Chelsea MI, US
Muhammad K. Sami - Ypsilanti MI, US
International Classification:
A61M 1/10
Abstract:
A system and method for detecting and mitigating a suction condition are disclosed. The method may include characterizing pump waveform signal, identifying and evaluating a characteristic of the waveform for an existence of a suction condition. In various embodiments, a change in harmonic spectral distribution will identify a probability of a suction condition. A speed of the pump may be adjusted to mitigate the suction condition.
