  • Braided stent
    Patent number: 6083257
    Abstract: A braided stent (1) for transluminal implantation in body lumens is self-expanding and has a radial expanded configuration in which the angle .alpha. between filaments is acute. Some or all of filaments (6,7) are welded together in pairs at each end (4,5) of the stent to provide beads (8), thereby strengthening the stent and assisting its deployment from a delivery device. The stent is preferably completely coated using a biocompatible polymeric coating, said polymer preferably having pendant phosphoryl choline groups. A method of making the stent by braiding and welding is described as well as a delivery device for deploying the device.
    Type: Grant
    Filed: April 28, 1998
    Date of Patent: July 4, 2000
    Assignee: Biocompatibles Limited
    Inventors: Alistair Stewart Taylor, Peter William Stratford, Yiannakis Petrou Yianni, Matthew John Woodroffe
  • Biocompatible crosslinked coating and crosslinkable coating polymer composition for forming such a coating
    Patent number: RE40816
    Abstract: A braided stent (1) for transluminal implantation in body lumens is self-expanding and has a radial expanded configuration in which the angle ? between filaments is acute. Some or all of filaments (6,7) are welded together in pairs at each end (4,5) of the stent to provide beads (8), thereby strengthening the stent and assisting its deployment from a delivery device. The stent is preferably completely coated using a biocompatible polymeric coating, said polymer preferably having pendant phosphoryl choline groups. A method of making the stent by braiding and welding is described as well as a delivery device for deploying the device. The present invention provides a biocompatible crosslinked coating and a crosslinkable coating polymer composition for forming such a coating.
