Since usage of Multichannel-Cochlear Implants (=CI) a lot research-efforts has been put into to improve technology implants. Various reasons can result reimplantation. In this case old models will be exchanged latest generation The question arises whether newest give more benefit for users.

We investigated whether pulmonary surfactant in rat lung transplants recovered during the first week post-transplantation, along with symptoms of the reimplantation response, and whether this recovery was affected by early surfactant treatment. The severity of pulmonary injury was varied by transplanting left lungs with 6-h and 20-h ischemia (n = 12 and 19, respectively). Half of the transplant...

BACKGROUND The approach to treat device infection in patients with implantable cardioverter defibrillator (ICD) or cardiac resynchronization therapy defibrillator (CRT-D) is a challenging procedure. Optimal treatment is complete extraction of the infected device. To protect these patients from sudden cardiac arrest while waiting for reimplantation and to avoid recurrent infection, a wearable ca...

2 Department of Orthopaedic Surgery, Harvard Medical School, Boston, MA Revision of the glenoid component in total shoulder arthroplasty (TSA) remains an unresolved problem. Even with meticulous surgical technique, available bone stock may preclude the implantation of a new glenoid component. Multiple studies have demonstrated that patients in whom a new glenoid can be placed have improved pain...

Introduction More than 50,000 people in Germany use a cochlear implant (CI). Potentially, revision surgery may become necessary any patient due to technical defect, medical or other reasons. The aim of the present study is analyze reasons leading CI reimplantation and calculate cumulative survival rate.

The present work compared the local injection of mononuclear cells to the spinal cord lateral funiculus with the alternative approach of local delivery with fibrin sealant after ventral root avulsion (VRA) and reimplantation. For that, female adult Lewis rats were divided into the following groups: avulsion only, reimplantation with fibrin sealant; root repair with fibrin sealant associated wit...

Achievement of optimal valve geometry in valve-sparing aortic root repairs is a prerequisite for favorable valve function and, therefore, the simplification of these procedures is of utmost importance. The aim of the study was to determine the feasibility of the new vascular graft for aortic valve reimplantation technique and evaluate the early and intermediate functional results. Five patients...

OBJECTIVES Sinuses of Valsalva are important in assuring the physiological function of the aortic valve. This study evaluates short-term clinical results of the reimplantation technique for aortic valve-sparing root replacement using a new prosthesis with three separate sinuses of Valsalva (sinus prosthesis). METHODS Between February 2009 and February 2011, a total of 23 patients (20 m/3 f; m...

BACKGROUND Progress in oncology could improve survival rate in children, but would probably lead to impaired fertility and puberty. In pre-pubertal girls, the only therapeutic option is the cryopreservation of one ovary. Three births have been reported after reimplantation of cryopreserved mature ovary. Conversely, reimplantation of ovary preserved before puberty (defined as immature ovary) has...

BACKGROUND Combined aortic valve repair and aortic valve-sparing surgery requires an approach determined by the leaflets and aortic root anatomy. METHODS Among patients referred for aortic root aneurysm, 114 patients underwent an aortic valve-sparing procedure in which a reimplantation or remodelling technique was used. The Gelweave Valsalva prosthesis (Sulzer Vascutek, Renfrewshire, UK) was ...
