Additively Manufactured Diamond for Energy Scavenging and Wireless Power Transfer in Implantable Devices

Advanced Functional Materials, EarlyView.
Additive manufacturing is expanding beyond mechanical prosthetics into microelectronic implants. This work presents a diamond‐titanium hybrid that enables wireless power transfer, localized heating, and flow sensing. The use of additive manufacturing combined with the biocompatibility of the diamond‐titanium hybrid material paves the way toward new ...

Transcatheter closure of a residual shunt with posteroinferior deficient rim after surgical closure of an ASD: a case report

BMC Cardiovascular Disorders, 2020
Background There are few reports in the literature of device closure of residual shunts following initial surgical closure of an atrial septal defect (ASD). This case study reports one such case.

Programmable Compliance in Small‐Diameter Vascular Grafts by Design of Melt‐Electrowritten Scaffold Architectures for In Situ Tissue Engineering

Advanced Healthcare Materials, EarlyView.
Small‐diameter vascular grafts with compliance tunable by design are fabricated via melt electrowriting. By controlling the winding angle of intertwined helical fibers, grafts with compliances matching those of human vessels, from veins to arteries, are realized. This holds the potential of avoiding a compliance mismatch, which has been identified as a

Malignant priapism due to penile metastases. Case series and literature review [PDF]

, 2016
Malignant priapism secondary to penile metastases is a rare condition. This term was originally used by Peacock in 1938 to describe a condition of painful induration and erection of the penis due to metastatic infiltration by a neoplasm.

Anesthetic considerations for video-assisted thoracoscopic surgery in a child with Glenn shunt for thoracic duct ligation and pleurodesis

Saudi Journal of Anaesthesia, 2018
Glenn shunt is an anastomosis between superior vena cava and right pulmonary artery to palliate patients with single ventricle physiology of the heart. Chylothorax is a frequent and troublesome complication after the creation of this shunt, which if not ...

Incidence of and Causes for Ventriculoperitoneal Shunt Failure in Children Younger Than 2 Years: A Systematic Review

Central European Neurosurgery, 2018
Objectives Ventriculoperitoneal (VP) shunting is commonly used to treat pediatric hydrocephalus, but failure rates are high. VP shunt failure in children is mostly caused by infection and/or proximal/distal shunt obstruction.

Plasma‐Polymerized Nanoparticles Presenting Fibrillin‐1 Drive Rapid Re‐Endothelialization of Vascular Grafts

Advanced Healthcare Materials, EarlyView.
Commercial vascular grafts are made from ePTFE, a highly hydrophobic, foreign material that fails at a high rate in small‐diameter applications. Plasma polymer nanoparticles (PPN) are a versatile material functionalisation tool, used here to present fibrillin‐1 fragment PF8 on the graft surface.
