Abstract
A piezoelectric medical device prepared by electrostatically spinning a copolymer of vinylidene fluoride and a second fluorinated hydrocarbon, and collecting the spun fibers on a suitable receiver. The medical device can be in the form of a vascular prosthesis, neural prosthesis, or wound dressing and the copolymer can be composed of a predominant amount of vinylidene fluoride.
Claims8
A biomedical device selected from the group consisting of a vascular prothesis, a neural prosthesis and a wound dressing exhibiting piezoelectricity prepared by electrostatically spinning under suitable conditions for the formation of piezoelectric fibers a copolymer suitable for direct contact with bodily fluids of a living organism of the following comonomers:
- a) from in the range of from about 50 to about 95 weight percent of vinylidene fluoride, and
- b) a second fluorinated hydrocarbon, selected from the group consisting of trifluoroethylene and tetrafluoroethylene,
- and collecting the spun fibers on a suitable receiver.
