Abstract
The present method comprises the steps of advancing the coated expansion member to the obstruction in a vessel and applying opposed forces on said expansion member in an axial direction to move the expansion member to an expanded configuration wherein the expansion member dilates the obstruction and the expansion member either passively or actively delivers a therapeutic agent or medicament to the obstruction.
Claims10
A method for dilating and delivering a medicament to an obstruction in a body passageway which comprises the steps of:
- advancing a mechanical dilatation and drug delivery catheter to a predetermined site with a body passageway, said catheter having an substantially cylindrical expansion member coated with a medicament, said expansion member being moveable between a first contracted configuration wherein said expansion member is defined by a first dimension extending in a radial direction, and a second expanded configuration wherein said member is defined by a second dimension extending in said radial direction;
- applying a force on said coated expansion member in an axial direction to move said expansion member between said first contracted configuration to said second expanded configuration wherein said expansion member dilates said obstruction or body passageway and delivers a medicament to an said obstruction or body passageway.
