Abstract
The present invention avoids a patient receiving a double dose of a therapeutic agent when a coated stent is overlapped with another coated stent within a vessel. A stent having a therapeutic coating on a portion of the stent is delivered within a vessel such that the portion of the stent not having a therapeutic coating is inserted within or overlaps a second coated stent. A radiopaque marker on the stent or delivery catheter guides positioning of the stent such that there is minimal or no overlap of the therapeutic coatings on the two stents.
Claims33
A first stent having a therapeutic coating designed for insertion into a second stent which also has a therapeutic coating, the first stent comprising:
- a stent framework;
- and
- a therapeutic coating disposed on only a portion of the stent framework.
A coated stent designed for insertion into another stent, comprising:
- a stent framework;
- a therapeutic coating disposed on at least a portion of the stent framework;
- and
- a non-therapeutic coating disposed on a portion of the stent framework.
A coated stent designed for insertion into another stent, comprising:
- a stent;
- a therapeutic coating disposed on the stent, wherein the coating is removable with a solvent;
- and
- a plurality of radiopaque markers applied to the stent.
A system for treating a vessel, comprising:
- a first stent, the first stent coated with a first therapeutic coating;
- a second stent, the second stent having at least a first portion and a second portion, the second portion coated with a second therapeutic coating.
A method of delivering overlapping stents in a vessel, comprising:
- delivering a first stent including a therapeutic coating disposed on at least a portion of an exterior surface of the stent framework, the first stent including one of a visible endpoint or a radiopaque marker;
- expanding the first stent;
- delivering a second stent including a therapeutic coating disposed on at least a portion of an exterior surface of the stent framework, the second stent including one of a visible endpoint or a radiopaque marker;
- positioning the second stent based on the visible endpoint or radiopaque marker of the first stent and the visible endpoint or radiopaque marker of the second stent such that there is minimal or no overlap of therapeutic coatings of the first and second stents;
- and
- expanding the second stent.
31-38. (canceled)
A stent delivery system, comprising:
- a catheter;
- a stent coupled to the catheter;
- a therapeutic coating on at least a portion of the stent;
- and
- a radiopaque marker on one of the catheter or the stent.
