Pulsatile Fluid Delivery System

US Patent:
7842003, Nov 30, 2010
Filed:
Dec 9, 2005
Appl. No.:
11/297989
Inventors:
Kenneth A. Jones - McKinney TX, US
Cristo Suresh Corera - McKinney TX, US
Richard S. Hayes - McKinney TX, US
Assignee:
Quest Medical, Inc. - Allen TX
International Classification:
A61M 37/00, F04B 43/12, A61N 1/362
US Classification:
604 611, 604 401, 4174771, 600 16, 600 17
Abstract:
A system for delivering blood, cardioplegia solution, and other medications or fluids in a pulsatile flow pattern to a patient during cardiopulmonary bypass is disclosed. In a preferred embodiment, a pumping apparatus having at least one chamber is utilized in which a pumping action is achieved by compressing one of the chambers with a piston mechanism, while allowing the other chamber to fill with fluid via retracting its respective piston. The instantaneous flow rate of either of the chambers is determined by the speed of the piston. In a preferred embodiment, a pulsatile flow of fluid is achieved by cyclically alternating the velocity of the piston between two different speeds. A desired average flow rate and/or delivery pressure and/or constant pulse pressure is maintained by adjusting the alternating velocities at the desired frequency and duty cycle. The calculations necessary to obtain a desired average flow rate are performed by a microprocessor, which also controls the movement of the pistons.

Targeted Sanguinous Drug Solution Delivery To A Targeted Organ

US Patent:
2004011, Jun 10, 2004
Filed:
Dec 3, 2003
Appl. No.:
10/726463
Inventors:
Richard Hayes - McKinney TX, US
Jakob Vinten-Johansen - Grayson GA, US
International Classification:
A61K009/22
US Classification:
604/890100
Abstract:
A system and method for precisely controlling the delivery of two fluids to a specific organ or region of a patient when one of the fluids breaks down the other fluid. The fluids are separately metered and are maintained in separate delivery lines until a point very near the target organ, preferably within twelve inches of the delivery site. In an exemplary embodiment, blood and a cardioplegic agent are supplied to the heart via the coronary arteries or coronary veins while adenosine, which provides a powerful protective influence on the myocardial cells during ischemia, is provided in a separate delivery line to prevent the breakdown of adenosine, which has a half-life of 13 seconds in the blood.
