Thesis (Ph.D.)--Drexel University, 2005.

Although blood pressure measurements are well developed, the existing technology in the field of Arterial Blood Pressure (ABP) measurements is not sufficient in terms of long-term ABP waveform assessment. To overcome existing limitations this dissertation proposes, models, designs and tests a new technique of ABP measurements: implantable arterial tonometry.

520 $a Although blood pressure measurements are well developed, the existing technology in the field of Arterial Blood Pressure (ABP) measurements is not sufficient in terms of long-term ABP waveform assessment. To overcome existing limitations this dissertation proposes, models, designs and tests a new technique of ABP measurements: implantable arterial tonometry.
520 $a The scope of this dissertation is to study how the geometry of the tonometer and its mechanical properties influence sensor output and stress/strain distribution inside the arterial wall. Two models of tonometer, analytical and numerical, are developed. The relationship between the tonometer response and its effective stiffness is calculated using a lumped parameter model. The contact pressure between the artery and the tonometer as well as the arterial wall stress/strain distribution is studied using a Finite Element numerical model.
520 $a Based on the theoretical results three prototypes are developed. The piezoelectric dual mode transducer is designed to measure the tonometer-arterial wall contact pressure. The series of in-vitro and in-vivo experiments test the static and dynamic responses of the tonometer.
520 $a The results indicate the tonometer's effective stiffness necessary to achieve less than 1% error in the dynamic response of the sensor. The geometry of the tonometer's measurement area is found, which results in less than 1% of error in quasi-static response of the sensor. In effort to find potential tissue remodeling areas, the internal arterial wall stress/strain distribution generated by the tonometer is found.
520 $a The experimental results complement the numerical analysis. The static and dynamic characteristics of the prototype tonometer obtained in-vitro and in-vivo are presented. The explanted tunica media remodeling effect is compared with FE analysis results.
520 $a The presented work states and solves basic problems of implantable arterial tonometry. In addition it provides the in-vitro and in-vivo examination of the theoretical results. The thesis develops tools of modeling, designs, and testing procedures for future researchers willing to develop implantable tonometers.
520 $a The thesis concludes with a novel design of the implantable tonometer.
