  • Publication number: 20180008753
    Abstract: Side-chain crystallizable (SCC) polymers are useful in various medical applications. In certain applications, heavy atom containing side-chain crystallizable polymers (HACSCCP's) are particularly useful. An example of a HACSCCP is a polymer that comprises a main chain, a plurality of crystallizable side chains, and a plurality of heavy atoms attached to the polymer. In certain configurations, the heavy atoms are present in an amount that is effective to render the polymer radiopaque. A polymeric material that includes an HACSCCP may be fabricated into a medical device useful for at least partially occluding a body cavity. For example, such a medical device may be an embolotherapy product. A polymeric material that includes a SCC polymer may also be fabricated into other medical devices, such as stents.

  • Patent number: 5899201
    Abstract: A hand held aerosol actuator involving an aerosol source and a chamber having walls defining a constriction aperture. The aerosol source communicates with the chamber and directs an aerosol dose along an axis into the chamber. The constriction aperture is coaxial with the exit orifice and is dimensioned such that the respirable mass of the aerosol dose is increased relative to the respirable mass of an aerosol dose expelled through a like actuator not having the constriction aperture.

  • Patent number: 5674592
    Abstract: Low energy surfaces based on nanostructured films exhibit advancing and receding contact angles for liquids such that (1) the difference between the advancing and receding contact angles approaches zero and (2) the advancing and receding contact angles approach 180.degree.. The low energy surface of the present invention comprises a nanostructured film coated with an organized molecular assembly (OMA). Advantageously, the chemical and wetting characteristics of the surface can be altered by changing the functionality of the OMA end groups exposed to the environment in contact with the surface of the nanostructured film.
