Tetrahydrofuran (co)polymers as potential materials for vascular prostheses.
Polyethers were studied as potential materials for vascular prostheses. By crosslinking poly(tetramethylene oxide)(PTMO) with poly(ethylene oxide)(PEO), hydrophilic networks were obtained containing PTMO as well as PEO. Attempts were made to reduce the crystallinity and melting point of PTMO because of the required elastomeric behaviour at body temperature. Compared to non-crosslinked PTMO, c...
متن کاملLate thoracic pseudo-aneurysm causing collapse of vascular prostheses.
The outcome of patients with thoracic vascular prostheses is usually uneventful. We report two cases of collapse of thoracic vascular prostheses which occurred ten and forty years, respectively, after the implantation. The diagnoses were obtained preoperatively by CT-scan or NMR and angiography. Both patients were successfully treated with prosthetic replacement by an open approach.
متن کاملPhysical Impacts of Compaction Treatments on PET Textile Vascular Prostheses
(Received: May 4, 2010; June 10, 2010) Abstract: Textile cardiovascular prostheses are woven or knitted structures made generally from biocompatible polyester fibres. After production, they have to undergo special treatments before packaging such as compaction. This treatment is necessary to reduce porosity especially for knitted structures, but it can modify poly(ethylene terephthalate) (PET) ...
متن کاملVisual prostheses.
The development of man-made systems to restore functional vision in the profoundly blind has recently undergone a renaissance that has been fueled by a combination of celebrity and government interest, advances in the field of bioengineering, and successes with existing neuroprosthetic systems. This chapter presents the underlying physiologic principles of artificial vision, discusses three con...
متن کاملNeural Prostheses
A neural prosthesis is a device that aims to restore or replace the functions of the nervous system that are lost to disease or injury. Examples include devices to improve hearing, vision, motor and cognitive functions. Neural prostheses artificially stimulate the nervous system to convey sensory information, activate paralysed muscles or modulate the excitability of neural circuits to improve ...
