Cosserat Rods for Modeling Tendon-Driven Robotic Catheter Systems [PDF]

open access: yesarXiv
Tendon-driven robotic catheters are capable of precise execution of minimally invasive cardiac procedures including ablations and imaging. These procedures require accurate mathematical models of not only the catheter and tendons but also their interactions with surrounding tissue and vasculature in order to control the robot path and interaction.

The involvement of cell-to-cell signals in the development of a bacterial biofilm.

open access: yesScience, 1998
Bacteria in nature often exist as sessile communities called biofilms. These communities develop structures that are morphologically and physiologically differentiated from free-living bacteria.

Clinical and Procedural Effects of Transitioning to Contact Force Guided Ablation for Atrial Fibrillation. [PDF]

open access: yes, 2019
Background: A major innovation in atrial fibrillation (AF) ablation has been the introduction of contact force (CF) sensing catheters. Objective: To evaluate procedural and clinical effects of transitioning to CF-guided AF ablation.

A multiple catheter technique for studies or hepatic metabolism and blood flow in dogs with portacaval transposition [PDF]

open access: yes, 1962
A technique is described for in vivo hepatic metabolic studies, employing a multiple catheterization technique in dogs with chronic portacaval transposition. The animals are studied in the unanesthetized state immediately after the insertion of catheters

Hydrodynamics of catheter biofilm formation [PDF]

open access: yesarXiv, 2009
A hydrodynamic model is proposed to describe one of the most critical problems in intensive medical care units: the formation of biofilms inside central venous catheters. The incorporation of approximate solutions for the flow-limited diffusion equation leads to the conclusion that biofilms grow on the internal catheter wall due to the counter-stream ...
