Silicone Elastomer Plombage for Severe Hemoptysis

Archives of Surgery, 1973
A 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, 1995
Silicone 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, 1973
Five 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, 1977
To 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, 1998
Fatigue-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, 2001
Electrorheological (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, 2007
We 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

Softness Evaluation of Silicone Elastomers

Chemistry Letters, 2011
Abstract We evaluated the softness of various silicone elastomers installed on a tactile evaluation system. The softness of the elastomers was reflected by the vertical force when subjects pushed the elastomers with their fingers. The moving behavior depended on the elastic properties of the contacted objects; namely, a pushing pattern ...

Self-lubricating silicone elastomer biomaterials

Journal of Materials Chemistry, 2003
Silicone has a relatively high coefficient of friction and silicone medical devices therefore lack inherent lubricity, leading to pain on device insertion and potential tissue trauma. In this study, higher molecular weight tetra(alkoxy)silanes, particularly tetra(oleyloxy)silane, have been used as crosslinkers in the condensation cure of a hydroxy end ...
