In nine dogs submitted to a severe myocardial ischaemic challenge, multiple prosthetic implants running from the descending aorta to myocardial tunnels were successful in sustaining effective ventricular contraction for a mean period of 27 minutes. A control series of five dogs and five animals, in which the prostheses clotted, developed ventricular fibrillation within six minutes of the ligati...
Introduction Titanium implants can be regarded as the current gold standard for restoration of sound transmission in the middle ear following destruction of the ossicular chain by chronic inflammation. Many efforts have been made to improve prosthesis design, while less attention had been given to the role of the interface. We present a study on chemical nanocoating on microstructured titanium ...
Due to the simplicity of their manufacture and placement, middle-ear prostheses are generally constructed using only a single 'ossicle'. The variety of pathologies frequently make it necessary to devise individual solutions and the results are often unsatisfactory. Many methods of improving the prostheses have been tried, with very mixed results. Even until recently, the fundamental assumptions...
