Thrombosis of Mechanical Mitral Valve Prosthesis

Journal of Cardiac Surgery, 2005
Obstruction of mechanical valve prostheses is a rare but potentially lethal complication following valve replacement surgery. Identifying the etiology and differentiation between thrombus, pannus, and vegetation obstructing the valve prosthesis can pose a diagnostic challenge.

Mechanical failure of omniphase penile prosthesis

Urology, 1988
We report a case of mechanical failure due to cable breakage in both cylinders of an OmniPhase penile prosthesis. The failure occurred six weeks after implantation and was manifested by inability to activate the device. X-ray films showed cable fracture at the point of insertion into the activator mechanism bilaterally.

Mechanical Failure with Malleable Penile Prosthesis

Urology, 2007
Mechanical failure with a malleable penile prosthesis is very rare, and no mechanical failure has been reported with the AMS 650 malleable penile prosthesis. A 67-year-old man, using the AMS 650 malleable penile prosthesis without a problem since 1999, presented with right penile deformity and difficulty in sexual intercourse for the preceding 2 months.

Finite element modeling of retinal prosthesis mechanics

Journal of Neural Engineering, 2009
Epiretinal prostheses used to treat degenerative retina diseases apply stimulus via an electrode array fixed to the ganglion cell side of the retina. Mechanical pressure applied by these arrays to the retina, both during initial insertion and throughout chronic use, could cause sufficient retinal damage to reduce the device's effectiveness. In order to
