Advanced Intelligent Systems, EarlyView.This work presents a robot‐assisted Doppler optical coherence tomography system for autonomous, wide‐field intraoperative assessment of microvascular anastomoses. Machine‐vision–guided probe positioning and adaptive scan planning enable three‐dimensional structural and hemodynamic imaging over extended vessel segments.

Wireless blood pressure sensor implantation in sheep: A detailed technique
Animal Models and Experimental Medicine, EarlyView.Twelve adult sheep underwent wireless blood pressure sensor implantation. The procedure lasted an average of 36 min, with mean systolic and diastolic blood pressures of 93 ± 6 and 65 ± 5 mmHg, respectively. This rapid, minimally invasive protocol is a powerful platform for cardiovascular device development.

The Dynamics of Pulsatile Blood Flow [PDF]
Circulation Research, 1954 The theory of dynamic fluid motion involving the forces manifested by mass, acceleration, viscous friction and vessel wall tension have been considered and studied when arterial blood flow and pressure are pulsatile. These studies and considerations have resulted in the conclusion that arterial blood pressure is dependent upon all of these parameters ...

Mathematical analysis of blood flow model through channels with flexible walls [PDF]
, 2011 A simplified mathematical model of blood flow through flexible arteries is developed and analyzed. The resulting system of non-linear, non-homogeneous PDE\u27s is analyzed numerically using the Richtmyer Lax-Wendroff method.

Advanced NanoBiomed Research, EarlyView.Despite significant advances, most academic research fails to result in medical products that benefit patients. This guide shares five key steps to help researchers close that gap: set clear goals, test thoroughly, protect ideas, build diverse teams, and partner with industry.
