Controlling hysteresis in superconducting constrictions with a resistive shunt

, 2015
We demonstrate control of the thermal hysteresis in superconducting constrictions by adding a resistive shunt. In order to prevent thermal relaxation oscillations, the shunt resistor is placed in close vicinity of the constriction, making the inductive ...

Endovascular laser treatment of mixed shunt

Veins and Lymphatics, 2017
In this paper we present our endovascular LASER treatment of mixed shunts. This technique is built according the CHIVA’s important principles: diastolic reflux is interrupts at its proximal origin by flush LASER obliteration while centripetal systolic ...

A Distinct Scenario of a Patient with Parkinson’s Disease and Comorbid Normal Pressure Hydrocephalus

Indian Journal of Neurosurgery, 2020
In literature, patients with coexistence of normal pressure hydrocephalus (NPH) and Parkinsons’s disease (PD) have been rarely reported. Herein, I illustrate the evaluation processes of a remarkable patient with PD and comorbid NPH from my experience ...

Shunt Infection

Archives of Pediatric Neurosurgery, 2021
The improvement in the management of hydrocephalus comes from the following: early diagnosis, radiological investigation, better knowledge of mechanisms, quality of material, surgical technique of implantation, less shunt complications (e.g.infections ...

Shunt-capacitor-assisted synchronization of oscillations in intrinsic Josephson junctions stack

, 2010
We show that shunt capacitor stabilizes synchronized oscillations in intrinsic Josephson junction stacks biased by DC current. This synchronization mechanism has an effect similar to the previously discussed radiative coupling between junctions, however,

Feasibility of an antegrade-retrograde single-sheath inverse technique via vertical puncture in dysfunctional hemodialysis arteriovenous fistula angioplasty

CVIR Endovascular
Background Stenosis resulting in dysfunctional dialysis access may occur simultaneously on the anastomotic and central venous side. The purpose of this study was to retrospectively evaluate the feasibility of a single sheath inverse technique using the ...

Carotid endarterectomy: to shunt or not to shunt. [PDF]

Stroke, 1988
Because of controversies in the cerebrovascular literature regarding the use of an intraluminal shunt in carotid endarterectomy, we report a randomized prospective study of 118 consecutive symptomatic patients receiving surgery within a single neurosurgical practice.

Multimodal Simulation of a Novel Device for a Safe and Effective External Ventricular Drain Placement

Frontiers in Neuroscience, 2021
BackgroundExternal ventricular drain (EVD) placement is mandatory for several pathologies. The misplacement rate of the EVD varies widely in literature, ranging from 12.3 to 60%.
