Biocompatible, hyaluronic acid modified silicone elastomers
Biomaterials, 2010Although silicones possess many useful properties as biomaterials, their hydrophobicity can be problematic. To a degree, this issue can be addressed by surface modification with hydrophilic polymers such as poly(ethylene glycol), but the resulting structures are usually not conducive to cell growth.

Silicone elastomers for reduced protein adsorption
Biomaterials, 2004Monofunctional poly(ethylene oxide) polymers of molecular weight (MW) 350, 750, and 2000, respectively, were modified with Si(OEt)3 groups. These polymers underwent classic condensation cure with hydroxy-terminated silicone polymers and Si(OEt)4 to give composites with poly(ethylene oxide) (PEO) rich surfaces under aqueous conditions, as shown by ...

Silicone Elastomer Plombage for Severe Hemoptysis
Archives of Surgery, 1973A 58-year-old man suffered massive, life-threatening hemoptysis secondary to cavitary tuberculosis. Silicone elastomer augmentation mammoplasty prostheses were inserted for cavitary collapse and as an urgent measure to control hemoptysis, with use of the well-known technique of extracostal subperiosteal plombage.

Thyroplasty Using A Silicone Elastomer Implant
Otolaryngologic Clinics of North America, 1995Silicone has been used in a variety of forms as a replacement for soft tissue for more than three decades in the United States. The safety of this practice has come under scrutiny recently as our knowledge of the local, systemic, and immune effects of silicone has expanded. Contrary to what was once thought, silicone is not biologically inert. Silicone

Silicone Elastomer Implantation Cyclodialysis
Archives of Ophthalmology, 1973Five eyes with severe secondary angleclosure glaucoma were operated upon using the silicone elastomer (Silastic) implantation cyclodialysis procedure. It was not possible to thereby significantly reduce the intraocular pressure except for one eye, which also underwent a cyclodiathermy.

Complications of Silicone Elastomer Prostheses
JAMA: The Journal of the American Medical Association, 1977To the Editor.— The report by Christie et al apparently correctly notes that silicone elastomer prostheses may produce foreign body reaction in a regional lymph node and synovitis. However, these mild inflammatory reactions have not been placed in proper clinical perspective. The authors correctly state, "Thousands of silicone elastomer...

Fatigue-resistant silicone elastomer formulations
Journal of Applied Polymer Science, 1998Fatigue-resistant elastomers have been prepared using various metal oxides as fillers in poly(dimethylsiloxane) (PDMS)-based elastomers. The judicious choice of inorganic fillers produced elastomers that were stable under cyclic testing at elevated temperatures.

Electrorheology of filled silicone elastomers
Journal of Rheology, 2001Electrorheological (ER) silicone elastomers containing particles based on silica (SiO2) and titania minerals (BaTiO3, Ba2Ti9O20, and BaTiO3/CaZrO3) were prepared and characterized. An electrical field was applied to align the particles during the cure of the silicone prepolymer.

Oxidation of Silicone Elastomer Finger Joints
The Journal of Hand Surgery, 2007We analyzed the oxygen content of 19 retrieved implants and 6 packaged implants to further understand the mechanism of degradation of silicone elastomer finger joints while in vivo.Nineteen Swanson (Wright Medical Technology, Arlington, TN) silicone elastomer finger joints were retrieved at revision surgery at an average of 7 years of use. Six packaged
