摘要： An apparatus prepares a medical device from a polymeric composition having properties such as increased visibility of the device and the ability to deliver therapeutic and other agents. The device is constructed with additives incorporated into the polymeric structure, such as a material that increases visibility of the device, while still maintaining desired mechanical characteristics such as high radial stiffness, minimized recoil values, and improved flexibility. The device can assume a wide range of geometries that are adaptable to various loading conditions In order to include performance-enhancing additives to the medical device without affecting mechanical performance, the additives are localized in discrete regions of a polymer structure from which a medical device will be formed. For example, a medical device can be prepared from a polymer form such as a tube containing radiopaque agent localized at its ends or in a desired pattern along the device.

摘要： A polymeric medical device is constructed from bioabsorbable polymers. The device is constructed from a tube comprised of at least one polymer. The polymer is treated at pre-determined heating and cooling temperatures to obtain a desired morphology. The morphology or arrangement of the polymeric structure ensures that the device maintains its shape characteristics to ensure proper modeling of the vessel. In particular, the crystallinity of the polymeric structure is adjusted so as to resist recoil. The device can also contain a therapeutic agent dispersed throughout the structure or coated on the structure in such a manner as to elute the therapeutic agent when implanted in an anatomical conduit. The device can also be constructed from a blend of polymers and other agents such as plasticizers.

摘要： The invention provides a method for making fur bearing strands from hides of fur bearing animals and a yarn from such strands suitable for producing a fur garment. The yarn has low stretch characteristics by virtue of treatment of the hide portions used to make it. Strands are made from hide portions joined side by side at abutting longitudinal edges and slit transversely of the joined portion. A yarn is made from the strands, which may be joined end to end, by longitudinally twisting them so that the fur is substantially about the exterior thereof.

摘要： The present invention provides an erasable colored pencil lead composition comprising a colorant, one or more binder resins, a fibrillatable or fibrillated material, and a filler. The colored pencil lead of the present invention produces marks on paper, which are easily erased by ordinary pencil eraser. The mark made using the composition has a cohesive nature that assists in the removal from paper in sheet or film like sections by the use of an ordinary eraser without smearing or leaving a residue. In a preferred embodiment, the composition is free or substantially free of low melting waxes or wax like materials. Examples of suitable binder resins include high density polyethylene, low density polyethylene, polypropylene, and high melting waxes. Examples of fibrillated or fibrillatable materials include fibrillatable or fibrillated polytetrafluoroethylene and ethylene-vinyl acetate copolymer. The colored pencil lead composition may further include a lubricant. Examples of suitable lubricants include particulate lubricants such as micronized PTFE and non-particulate lubricants such as alkoxylated materials, e.g., polyethylene glycols. The present invention further provides a process for using the colored pencil lead composition. The present invention further provides a process for preparing the colored pencil lead of the present invention.

摘要： A stent is positioned on an undersized mandrel and the stent is coated with an excess of a polymer and drug solution. The stent is rotated to spin off the excess of the coating. The stent is then moved into a new, clean position on the mandrel. The process is repeated a few times, after which time the coating is already dry and non-sticky. This process forms a conforming coating. Various important polymer solution parameters include viscosity, solvent evaporation rate and several others. The actual type of coating polymer is not as important as how the surface of the stent is treated, according to the steps described herein.
