Abstract:
1. A cardiovasculature simulator system suitable for training and testing medical devices comprising: a cardiac system module for simulating cardiac functioning of a patient having an atrium assembly for simulating blood flow through an atrium of a heart and a ventricle assembly for simulating blood flow through a ventricle of a heart, said atrium assembly comprising a rigid outer casing sized and shaped to receive a pressurized pneumatic fluid, an expandable member positioned within said rigid outer casing, and a flexible, blood simulating fluid filled inner atrium chamber operatively coupled to said expandable member, said flexible, blood simulating fluid filled inner atrium chamber constructed and arranged to contract when said expandable member expands, thereby causing said blood simulating fluid stored within to be ejected out, and expand when said expandable member is depressurized, said ventricle assembly comprising a flexible ventricle assembly inner member fluidly coupled to said flexible inner atrium chamber whereby said blood simulating fluid exiting said flexible inner atrium chamber is received by said flexible ventricle assembly inner member and a rigid ventricle assembly outer member surrounding said flexible ventricle assembly inner member, said ventricle assembly inner member and said rigid ventricle assembly outer member being separated by a space therebetween, whereby pneumatic pressurized fluid inserted within said space exerts a force upon said flexible ventricle assembly inner member causing said flexible ventricle assembly inner member to eject said blood simulating fluid stored within, said flexible ventricle assembly inner member expanding when said pneumatic pressurized fluid exits said space between said inner flexible member and said outer rigid member; a vasculature system module comprising at least one tubing adapted to have anatomical or physiological characteristics of a normal or diseased human artery or vein and fluidly connected to at least a portion of said cardiac system module; a pneumatic supply module comprising a device for generating said pressurized pneumatic fluid fluidly connected to at least a portion of said atrium assembly and to at least a portion of said ventricle assembly whereby pressurized pneumatic fluid is delivered to said atrium assembly independently of delivery of pressurized pneumatic fluid to said ventricle assembly; and a control unit comprising one or more logic chips configured to control or modify one or more operational parameters of the cardiovasculature simulator system; whereby said cardiovasculature simulator system provides an anatomically and physiologically accurate representation of a cardiovasculature system in normal or diseased states.
