Publication number: 20110066227Abstract: A stent having one or more beneficial agents which enhance the healing effect of the stent. The agent is positioned within a reservoir. The reservoir dynamically releases the agent when the stent is expanded. The reservoir makes use of various changes in stent shape during expansion to assure proper release of the agent. Agent release can be modulated at various points along the stent and with various rates of release. The reservoirs can also be cooperatively combined with features that enhance stent flexibility, structural integrity, and which prevent recoil.Type: ApplicationFiled: September 17, 2009Publication date: March 17, 2011Applicant: BOSTON SCIENTIFIC SCIMED, INC.Inventors: Michael P. Meyer, Timothy S. Girton, Dennis Boismier, Daniel Gregorich, Kim Robertson, Liza Davis, Cory Hitzman, Samuel Robaina, Doug Thesingh

Publication number: 20090240318Abstract: A bifurcated stent that is positionable adjacent to a branched body vessel. The stent includes a number of stent members at least some of which have slits extending through them. The slits are positioned relative to the tensile and compressive forces imposed by stent expansion to enhance the flexibility of the stent members. The slits can be positioned to increase stent compression about a catheter, increase how far the stent can be bent during catheter deployment, and allow specific portions of the stent to have improved flexibility. The slits can allow the stent to assume a bent shape, and compensate for rigidity imposed the bifurcating side branch. The slits can be combined with curved sections to create a highly flexibly stent.Type: ApplicationFiled: March 19, 2008Publication date: September 24, 2009Applicant: BOSTON SCIENTIFIC SCIMED, INC.Inventors: Aaron Chalekian, Joe Groff, Michael P.

Publication number: 20080281395Abstract: A bifurcated stent having a side branch constructed out of a bioabsorbable material. The side branch comprises one or more bio cells which are flexible and easily deformable when the stent is in the unexpanded state. The bio cells have a locking member which fixedly holds the bio cells in place once the stent assumes the expanded state. The locking member uses oppositely directed hooks or ratchet teeth to prevent contraction in the bio cells once the expanded state is assumed. By having an appropriate alternation between flexibility and rigidity the side branch is flexible enough to deal with the geometric difficulties of bending and deploying a side branch while being fixed and rigid enough to properly support and scaffold a side branch assembly. The deployment of the side branch can be facilitated by the use of a ratcheting device. The side branch can also have a flared shape.Type: ApplicationFiled: May 7, 2007Publication date: November 13, 2008Applicant: Boston Scientific Scimed, Inc.Inventors: Tracee Eidenschink, Todd Bethel, Thomas E.
