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.

Cellular events in the mechanisms of prosthesis loosening

Clinical Materials, 1991
The functional restoration of a joint damaged by trauma or disease is obtained by prosthetic surgery. In particular the implantation of hip prostheses is regarded as routine in orthopedic surgery and thorough research has been developed in this field.

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.

A Compliant Mechanism as a Sternum Prosthesis

2020
This paper presents a three-dimensional design of a compliant mechanism as a transmission system for its application in a novel human sternum prosthesis. The proposed compliant mechanism design is able to generate a coordinated movement between ribs during the respiratory process in human beings.

Mechanical failure of a St. Jude Medical prosthesis

The American Journal of Cardiology, 1991
Abstract The St. Jude Medical (SJM) prosthetic cardiac valve is a low-profile, bileaflet mechanical valve with an excellent record of durability and a low overall complication rate.1–3 Mechanical failure is a rare occurrence with this valve.4 We report a case of mechanical failure of a SJM prosthesis due to leaflet fracture with subsequent ...

The Mechanical Testing of a Sliding Meniscus Knee Prosthesis*

Clinical Orthopaedics and Related Research, 1978
A 3-component sliding meniscus knee prosthesis was tested mechanically to evaluate the direct loads and the anteroposterior and mediolateral bending moments on the prosthetic components during the loading phase on a pendulum prosthesis testing machine. The bending moments changed with variation of the component positions.

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

Mechanical Failure of the Repiphysis Expandable Prosthesis

The Journal of Bone and Joint Surgery-American Volume, 2010
The current treatment of osteosarcoma includes neoadjuvant chemotherapy followed by wide resection of the tumor and postoperative chemotherapy. While amputation of the extremity was once the mainstay of treatment, medical and surgical developments over the last several decades have led to the success of limb-salvage surgery1,2.

[Mechanical fatigue of an arterial prosthesis].

Presse medicale (Paris, France : 1983), 1984
This case study reports the analysis of a knitted polyester arterial prosthesis that was implanted in an 18-year old patient for five years following a bicycle accident which injured the left external iliac artery. In spite of the prosthesis, the patient continued to participate in competitive cycling.
