A novel power supply system for puborectails ‐like artificial anal sphincter
This article presents a new designed PSS includes a new tr anscutaneous energy transfer (TET) system, a heat reduction system, and a safety usage system. The new PSS reduces the total size of PAAS by at least 30%. New designed TET system can satisfy Qi standard, and render a power of 3w to fulfill the requirement of fast charging and normal use of PAAS at t he distance of 15.5mm when frequency of TET system is 110kHz, which previous TET system can hardly achieve. Heat reduction system helps to reduce the heat generated during TET charging. It can reduce heat by 40% during the same period of time of TET charging. Safety usa...

In Vitro Study on the Dynamics of Blood Flow Impelled by an Alternating Current Magnetohydrodynamic Blood Pump
This study demonstrated several findings: (i) Continuous sheep blood flow can be achieved; (ii) The blood cell counts remained unchanged after 3 h of exposure to an alternating magnetic field; (iii) Compared with the c ontrol group, the high‐ and low‐shear viscosities of the whole blood from the sheep significantly decreased after 3 h of exposure to an alternating magnetic field (P< 0.05 andP< 0.01, respectively). Plasma viscosity was significantly reduced after exposure to high ‐intensity alternating magnetic fields (P< 0.001); (iv) The cytoplasm of blood cells (especially erythrocytes) became lighter in co...

Device exchange versus nonexchange modalities in left ventricular assist device ‐specific infections: A systematic review and meta‐analysis
AbstractNo standardized treatment algorithm exists for the management of continuous ‐flow left ventricular assist device (CF‐LVAD)‐specific infections. The aim of this systematic review and meta‐analysis was to compare the outcomes of CF‐LVAD‐specific infections as managed by device exchange to other treatment modalities not involving device exchange. Electronic search was performed to identify all studies in the English literature relating to the management of CF‐LVAD‐specific infections. All identified articles were systematically assessed for selection criteria. Thirteen studies with 158 cases of CF‐LV...

Application of polycaprolactone, chitosan, and collagen composite as a nanofibrous mat loaded with silver sulfadiazine and growth factors for wound dressing
AbstractFabrication of nanofibrous biomaterials composed of natural and synthetic materials that incorporated with antibiotic and growth factors with controlled release manner is an attractive topic in wound healing. The purpose of this study was to prepare optimal composite of materials as biomimetic nanofibrous mats for application in wound healing. The mat was prepared of polycaprolactone (PCL) in the bottom, chitosan/poly ethylene oxide (Cs/PEO) in the middle, and PCL/collagen (PCL/Coll) in the top layer. A panel of standard characterization tests of nanofibrous mat was performed and its compatibilities in strength and...

Multi ‐Objective Genetic Algorithm Assisted by an Artificial Neural Network Metamodel for Shape Optimization of a Centrifugal Blood Pump
AbstractA centrifugal blood pump is a common type of the pump used as a left ventricular assist device (LVAD) in the medical industries. The reduction of the LVADs hemolysis level to reduce the blood damage is one of the major concerns in designing of such devices. Also, the enhancement of the LVADs efficiency to decrease the battery size is another design requirement. The blood damage critically depends on the state of the blood being pumped. Besides the blood state, the blood damage also depends on the pump impeller and volute geometries. In this research, a multi ‐objective optimization of a centrifugal blood pump is ...

A New Template and Teleoperation System for Human ‐Guided Spine Surgery
In this study, a new method was introduced to consider the issues and we tried to reduce the risk of pedicle screw placement and drilling process. To put pedicle screws in the correct position and orientation, a specific drill guide is designed and fabricated by additive manufacturing technology. In addition, since the drilling process is remarkably important and it is usually dependent on surgeon skill, therefore a teleoperation system is proposed to perform this task. In order to let the surgeon to have better control on the patient, a control scheme including position and velocity signals along with surgeon force and re...

Efficacy of an artificial pancreas device for achieving tight perioperative glycemic control in living donor liver transplantation
In this study, we aimed to control the perioperative glucose levels consecutively for 24  hours from the induction of anesthesia. The average blood glucose level in the artificial pancreas group was significantly lower than that in the sliding scale group (118 vs. 141 mg/dL,P  <  0.05). The postoperative bacterial infection rate of the artificial pancreas group was significantly lower than that of the sliding scale group within one month after LDLT (35.7% vs. 78.6%,P  <  0.05). Multiple regression analysis showed non‐application of artificial endocrine pancreas as a significant risk factor of posttransplant i...

Three ‐Dimensional Numerical Simulations of Aspiration Process: Evaluation of Two Penumbra Aspiration Catheters Performance
AbstractAcute ischemic stroke (AIS) is the leading cause of mortality and disability worldwide. AIS occur while cerebral arteries become blocked by embolism or thrombosis. Aspiration thrombectomy is a promising interventional device to extract massive clots from occluded cerebral arteries. The aim of this article is to develop a computer ‐aided method to clarify the performance of aspiration catheter and identify the risks of aspiration for each specific AIS patient. In order to simulate the aspiration process, a three‐dimensional fluid‐structure interaction (FSI) method was developed. The blood clot was modeled as a...

Minimally Invasive Left Ventricular Assist Device Implantation: A Comparative Study
AbstractLeft ventricular assist device (LVAD) is now a routine therapy for advanced heart failure. Minimally invasive approach via thoracotomy for LVAD implantation is getting popular due to its potential advantage over the conventional sternotomy approach in terms of reduced risk at re ‐operation due to sternal sparing. We compared the approaches (thoracotomy and sternotomy) to determine the superiority. Minimally invasive approach involved fitting of the LVAD inflow cannula into left ventricle apex via left anterior thoracotomy and anastomosis of outflow graft to ascending aort a via right anterior thoracotomy. In the ...
