Claims8
A surgical needle having a coating thereon, the coating formed from a coating mixture comprising at least one polydialkylsiloxane having a molecular weight sufficient to provide a viscosity of the coating mixture of at least about 10,000 cp and at least one siliconization material.
A surgical needle having an interpenetrating networked coating thereon, the coating formed from a coating mixture comprising at least one polydialkylsiloxane and at least one other siliconization material which does not covalently bond with the polydialkylsiloxane.
