Evaluation of 3D Curvature and Lead Stress of Transvenous Right Ventricular Leads: The Human Use Conditions Study (HUCS)

September 9, 2023

Author(s)

Jonathan Piccini, Tim Quinn, Lucas Koepke, James Dawson, Nicki Mara, Jason Santelli, Diane Muff, Jordan Savela, Alex Felber, Michael Friedrich, Jens Rump, Felix Tschentscher, Jake Benzing, Charles Swerdlow

Transvenous leads of cardiac implanted electronic device (CIED) systems are meant to last the life of the patient, but they are at risk for conductor fatigue

Multiple Changepoint Analysis of Noisy Nonlinear Data with an Application to Modeling Crack Growth in Additively Manufactured Titanium

December 5, 2019

Author(s)

Lucas N. Koepke, Jolene D. Splett, Timothy P. Quinn, Nikolas W. Hrabe, Jake T. Benzing, Michael R. Frey

Noisy measurement data pose a challenge for changepoint analysis, especially in the presence of multiple changepoints and when the model is nonlinear. We

Hot isostatic pressing (HIP) to achieve isotropic microstructure and retain as-built strength in additive manufacturing titanium alloy (Ti-6Al-4V)

September 23, 2019

Author(s)

Jake T. Benzing, Nikolas W. Hrabe, Timothy P. Quinn, Ryan M. White, Ross A. Rentz, Magnus Ahlfors

Hot isostatic pressing (HIP) treatments are used to seal internal porosity because defects exist in as-built Ti-6Al-4V parts produced by electron beam melting

The Reproducibility of a Proposed Standard Fatigue Test for Cardiac Device Leads

August 1, 2019

Author(s)

Timothy P. Quinn, Jolene D. Splett, Joseph D. McColskey, James Dawson, David Smith, Adam Himes, Daniel Cooke

The Transvenous Cardiac Leads Working Group of the Cardiac Rhythm Management Devices Committee of The Association for the Advancement of Medical Instrumentation

Fatigue Properties of a Titanium Alloy (Ti-6Al-4V) Fabricated Via Electron Beam Melting (EBM): Effects of Internal Porosity and Residual Stress

January 1, 2017

Author(s)

Nikolas W. Hrabe, Thomas H. Gnaeupel-Herold, Timothy P. Quinn

A deeper understanding of microstructural influences on the fatigue properties of Ti-6Al-4V made using electron beam melting (EBM) is necessary before this
