Ocular Biocompatibility of Nitinol Intraocular Clips

Biocompatibility of nitinol stapes prosthesis.

OBJECTIVE Use of the SMart piston, a nitinol-based, self-crimping prosthesis in stapes surgery may allow improved functional results because of better sound transmission properties at the incus-prosthesis interface because of the elimination of manual crimping. Possible disadvantages include thermal damage or strangulation of the incus and its mucoperiosteum or nickel intolerance. The goal of t...

Traumatic fracture of nitinol thermoreactive sternal clips.

Median sternotomy can be associated with significant morbidity, including non-union, dehiscence and mediastinitis. The use of flexible thermoreactive sternal clips has been introduced recently as an alternative method of sternal closure and is advocated in patients at increased risk of sternal breakdown. It is associated with a decreased incidence of sternal complications as well as allowing fa...

Biocompatibility of Intraocular Lenses

The performance of an intraocular lens is determined by several factors such as the surgical technique, surgical complications, intraocular lens biomaterial and design, and host reaction to the lens. The factor indicating the biocompatibility of an intraocular lens is the behavior of inflammatory and lens epithelial cells. Hence, the biocompatibility of intraocular lens materials is assessed in...

Post-traumatic symmetrical diastasis after sternal synthesis with nitinol clips.

Case report: osteogenesis imperfecta, internal mammary artery graft & nitinol clips

BACKGROUND Osteogenesis imperfecta is a genetic disorder of connective tissue causing mostly left-sided heart valves and aortic root pathologies, but a coronary artery involvement reflecting an increased sensitivity to cardiovascular risk factors is also suspected in this patient population. CASE PRESENTATION We report a 38-year-old patient with an osteogenesis imperfecta and a typical presen...
