- 1. A method to create a more favorable flow regime in a lumen, comprising creating an artificial shape in the lumen to at least one of eliminate flow disturbances and enhance aspects of fluid flow through a treatment site.
- 22. A stent for implantation in a lumen to create a more favorable flow regime, comprising a stent being configured for establishing an artificial shape in the lumen for altering flow characteristics to at least one of eliminate flow disturbances and enhance aspects of fluid flow through a treatment site.

33. A stent comprising:
-
a first stent segment configured to have a first stent segment cross-sectional area in an expanded state of the stent;
a second stent segment longitudinally offset with respect to the first stent segment and configured to have a second stent segment cross-sectional area in an expanded state of the stent;
a third stent segment configured to assume a tapered stent segment configuration in an expanded state of the stent, the tapered stent segment configuration connecting the first stent segment to the second stent segment, the stent being configured such that, in an expanded state thereof in a lumen, it manipulates a flow of blood in the lumen so as to induce a more favorable flow regime at a deployment location of the stent relative to a flow regime that would have been generated had a straight stent been deployed at the deployment location for reducing a risk of restenosis at the deployment location. - View Dependent Claims (34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54)

55. A method of deploying a stent comprising:
-
delivering the stent to a deployment location in a lumen;
expanding the stent such that, in an expanded state thereof, the stent comprises;
a first stent segment having a first stent segment cross-sectional area;
a second stent segment longitudinally offset with respect to the first stent segment and having a second stent segment cross-sectional area; and
a third stent segment having a tapered stent segment configuration, the tapered stent segment configuration connecting the first stent segment to the second stent segment, the stent being configured such that, in the expanded state thereof in the lumen, it manipulates a flow of blood in the lumen so as to induce a more favorable flow regime at a deployment location thereof relative to a flow regime that would have been generated had a straight stent been deployed at the deployment location for reducing a risk of restenosis at the deployment location. - View Dependent Claims (56, 57, 58, 59)

60. A stent comprising:
-
a stent envelope adapted to be deployed at a deployment location in a lumen; and
means associated with the stent envelope for controlling a flow of blood in the lumen when the stent envelope is in its expanded state so as to induce a more favorable flow regime at the deployment location of the stent envelope relative to a flow regime that would have been generated had a straight stent envelope been deployed at the deployment location for reducing a risk of restenosis at the deployment location.
