RMBS 2008
Keywords: radial expansion, stent durability, deflection, mock vessels, coronary artery
Abstract
Coronary artery disease results in hardening of the arteries. The main reason is that cholesterol and plaque build up on the inner walls of the arteries. This results in restricting the blood flow to the heart causing injury to the heart muscle. Recently, non-surgical processes are being used to open up …
Linear Elastic Mechanics of Mock Arteries: Empirical Versus …

Keywords: mock artery, compliance, laser, high speed photography, conversion, linear elastic mechanics, vascular stents, durability
Abstract
The relationship between the pressure inside a cylindrical mock vessel and the change in radius is called radial compliance. It has been postulated that it is the internal change in radius with pressure that has a significant effect on blood flow disturbance…
Frequency Dependent Hysteresis of Silicone and Latex Mock Arteries Used in Stent Testing

RMBS 2005
Keywords: Compliance, Latex, Silicone, Artery, Frequency, Hysteresis, Stent, Testing, Vessels
Abstract
Mock arteries also called as mock vessels are one of the best alternatives available to researchers in evaluating the mechanical characteristics and durability of intravascular medical products without having to use animal and human clinical studies. The behavior of mock arteries depends on the frequency of loading. This makes …

Introduction:
Frequency response characteristics of mock arteries play a very significant role in high frequency durability testing of medical devices such as grafts and stents. In vitro durability testing of stents depends on cyclic load applied by the mock artery on the medical device.
Comparing Several Analytical Methods When Determining Dynamic Compliance of Arteries and Vascular Grafts
by | SFB 2005 | Publications, Compliance, Silicone Mock Arteries
Ramesh, R, Conti JC
SFB 2005
Introduction
Proper evaluation of mechanical characteristics of intravascular medical products often makes it necessary for researchers to conduct animal studies. Silicone mock arteries used in medical device testing have been proven to be the better alternative to animals. Radial compliance of mock arteries depends on radius and internal pressure and plays a critical role in in vitro experiments. Mock arteries are tested for radial compliance according to standards set by the AAMI/ISO committee…

There has been a disturbing number of unexpected mechanical failures in deployed vascular stents and stent grafts. An analysis of the mechanical properties of mock arteries used to carry out standard durability testing on the aforementioned medical products suggests that some of the problems might be related to a frequency dependent change in the properties of these recipient vessels. This could lead to…

The Design, Fabrication and Characterization of Mock Latex Aorto-Iliac Bifurcations
by | SFB 1998 | Publications, Silicone Mock Arteries

SFB 1998
Introduction
Mock arteries made of latex or other materials greatly aids the development of medical products in that certain durability and performance characteristics can be determined in vitro. It is critically important, however, that the dimensions and three-dimensional mechanical properties of these devices be precisely known. Up until now, we have been unable to design aorto-iliac bifurcations to be used …
