  • Visualization through an opaque medical device component
    Patent number: 6544222
    Abstract: A method and medical device component allowing visualization through the opaque material used to form the component. In a method of the invention for visualization through a medical device component formed of a porous opaque material, a fluid is applied to the porous material which has a refractive index substantially similar to the refractive index of the porous material, so that the transparency of the porous material is increased. In one embodiment, the medical device component is a catheter balloon.
