A 3D‐Printed Blister Test Platform for Quantifying Biointerface Adhesion Mechanisms
Advanced Materials Interfaces, EarlyView.A 3D‐printed blister platform enables energy‐resolved characterization of soft hydrogel–rigid interfaces. Integrating precision pressure control with hyperelastic modeling directly quantifies adhesion energy (G) and R‐curve toughening. Results reveal that modulating hydrogel concentration and surface roughness drives a tunable transition from cohesive ...

An Injectable Electroactive Hydrogel Engineered for Stable Bioelectronic Interfaces
Advanced Materials Interfaces, EarlyView.Injectable electroconductive hydrogels enable soft, conformal, and stable bioelectronic interfaces for electroceutical therapies. A catechol‐modified hyaluronic acid/alginate/edge‐functionalized graphene platform combines wet adhesion, shear‐thinning injectability, tissue‐matched mechanics, and electrochemical functionality.

To implant or not to implant: emergency orbital eviscerations with primary orbital implants
Eye, 2021To evaluate the outcomes of orbital evisceration with primary implant placement in acutely infected/inflamed eyes, using implant exposure/extrusion as a surrogate of success. To contextualise this with previously published literature.A retrospective case series of all patients with acutely infected/inflamed eyes undergoing urgent orbital evisceration ...

The Bioceramic Implant: Evaluation of Implant Exposures in 419 Implants
Ophthalmic Plastic & Reconstructive Surgery, 2010To compare the rate of exposure in the immediate 3-month postoperative follow-up period with the rate of exposure after the immediate postoperative period in 419 anophthalmic patients with a bioceramic (aluminum oxide) orbital implant.This is a retrospective, clinical case series of 419 patients who received a bioceramic orbital implant.

For simple constructions a mechanical analysis to determine internal stresses and deformation is possible using theoretical formulas. However, for complex constructions, like joint prostheses, this is not possible. Numerical simulation of internal stresses and deformations offers a solution for these constructions. The so-called Finite Element Analysis

Current Pharmaceutical Biotechnology, 2013
Cochlear implants have evolved to become the treatment of choice for severely hearing-impaired patients. Speech signals are picked up by a microphone, processed and then delivered to the stimulating electrodes (the current maximum number being 22) that are placed on an electrode array implanted into the scala tympani of the cochlea. The target cells of

The Totally Implantable Cochlear Implant
Ear & Hearing, 2007The concept of a totally implantable cochlear implant (TICI) offers the following advantages over the present generation of semi-implantable cochlear implants. These advantages include (1) cosmetics: deafness can be "hidden," because there is no external hardware during use; (2) no external hardware (e.g., cables, speech processor) to fail or be ...

Implants and implant reactions
Diagnostic Histopathology, 2016Abstract Total joint arthroplasty is one of the most successful of all operations, but arthroplasty failures do occur. By evaluating the retrieved devices and periprosthetic tissues, pathologists can often recognize clues about the mechanism of arthroplasty failure, information that can be of value to treating physicians, manufacturers and regulatory ...

The Development Of Implants And Implantable Materials
Otolaryngologic Clinics of North America, 1995Biomaterials are the building blocks of implant technology. They enable implants to function properly and endure the harsh environment of the human body but they are often the cause of implant failure. To reduce failure rates and substantially improve implant function, new biomaterials must be developed.
