Penile prosthesis surgery plays a vital role in the treatment of erectile dysfunction (ED). As far as outcome is concerned, it is one of the most rewarding procedures for both patients and surgeons. We describe our surgical technique for implantation of the three-piece inflatable penile prosthesis and point out the major surgical pitfalls accompanying this procedure and their specific managemen...

purpose: to determine the efficacy of primary placement of a titanium sleeve and peg on hydroxyapatite (ha) orbital implants. methods: this retrospective non-comparative interventional case series was performed on 34 patients undergoing enucleation. a standard enucleation technique with primary ha implantation was performed, in which titanium sleeve and peg were placed primarily during the init...

The development of ischemic gangrene of the penis following implantation of prosthesis is unusual, and very few cases are available in the literature. As a result, no established treatment protocol is available. We report our experience within a case of gangrene of the glans following implantation of a three-component prosthesis. We present a 53-year-old male, smoker with diabetes and hyperchol...

We review recently obtained results for CMOS (Complementary Metal Oxide Semiconductor) imaging devices used in biomedical applications. The topics include dish type image sensors, deep-brain implantation devices for small animals, and retinal prosthesis devices. Fundamental device structures and their characteristics are described, and the results of in vivo experiments are presented. key words...

BACKGROUND Percutaneous aortic valve implantation by an antegrade transvenous approach has been described but is problematic. Retrograde prosthetic aortic valve implantation via the femoral artery has potential advantages. Percutaneous prosthetic aortic valve implantation via the femoral arterial approach is described and the initial experience reported. METHODS AND RESULTS The valve prosthes...

Transcatheter aortic valve implantation (TAVI) has evolved as a routine procedure to treat selected high-risk patients with severe aortic stenosis. The new J-Valve prosthesis is designed for antegrade transapical implantation, it is characterized by a porcine aortic prosthesis attaching to a self-expandable Nitinol stent. The key feature of the device are three U-shape anatomically oriented dev...

Transvenous endocardial pacemaker (PM) implantation is contraindicated in patients with a mechanical tricuspid prosthesis. These patients usually undergo epicardial lead implantation. This case shows the implant of left ventricular (LV) pacing lead through the coronary sinus (CS) in a patient with high surgical risk. A 77-year-old woman with slow atrial fibrillation, left anterior hemiblock and...

Given the loading characteristics of the joint and given the bone in which the prosthesis has to be implanted, stress values may be limited by using an optimal prosthesis design) a prosthesis and interconnecting layer with optimal material properties and an optimal implantation procedure as to its mechanical consequences. It has been recognized recently in orthopaedic research literature that t...

BACKGROUND Severe peripheral arterial disease may pose a limitation to the applicability of trans-arterial aortic valve implantation in patients who are otherwise candidates. For this reason, transapical aortic valve implantation has been proposed as a possible alternative. OBJECTIVE To evaluate the acute safety and performance of a specially designed delivery system, the CoreValve Tranzap de...

INTRODUCTION AND OBJECTIVES Conduction disturbances often occur after CoreValve transcatheter aortic valve implantation. The aim was to analyze which cardiac conduction changes occur in patients with aortic stenosis treated with this type of prosthesis. METHODS A total of 181 patients with severe aortic stenosis treated with this prosthesis and studied by electrocardiography between April 200...
