Apparatus and method for treating intravascular disease
First Claim
1. A method of treating a treatment site in a blood vessel, the method comprising:
- providing an apparatus including a first deployable structure and a second deployable structure;
inserting the apparatus into the vessel adjacent the treatment site such that the first deployable structure is disposed adjacent the treatment site, and the second deployable structure is disposed at a location proximal or distal to the treatment site;
introducing a treatment material into the vessel proximate the treatment site;
deploying the second deployable structure within the vessel; and
deploying the first deployable structure adjacent the treatment site to create movement of the treatment material adjacent the treatment site.

Abstract
Medical devices and methods of treatment using medical devices, and more particularly, methods of treating a treatment site in a blood vessel and devices or apparatuses for use therewith. In some embodiments, a method and apparatus for treating a treatment site in a blood vessel using fluid movement or agitation adjacent the treatment site is disclosed. In some embodiments, an apparatus is provided including one or more deployable structures adapted to create fluid movement within the vessel. The apparatus is inserted into the vessel, and the deployable structure is positioned adjacent the treatment site. The deployable structure is used to create fluid movement adjacent to the treatment site. In some embodiments, a treatment material, such as a medicine or drug, is introduced into the vessel proximate the treatment site, and the deployable structure is used to create fluid movement or agitation adjacent the treatment site to create a better interface between the treatment site and the medicine, or to move the medicine into the treatment site. In some embodiments, the fluid movement created by the deployable member aids in removal of tissue or other material from the treatment site.

25. A method of treating a treatment site in a blood vessel, the method comprising:
-
providing an apparatus including a catheter including an elongated tubular body having a body wall defining an outer surface and an inner lumen, the body wall including one or more openings defined therein extending from the lumen to the outer surface, and the apparatus further including an elongated core member disposed within the lumen for selective movement within the lumen, the core member including a fluid moving structure attached thereto;
inserting the apparatus into the vessel adjacent the treatment site such that at least one of the one or more openings is disposed adjacent the treatment site;
selectively moving the core member such that the fluid moving structure extends through the one or more of the opening disposed adjacent the treatment site; and
moving the fluid moving structure to create movement adjacent the treatment site. - View Dependent Claims (26, 27, 28, 29, 30, 32, 33, 34, 35, 36, 37, 38, 39, 40)

41. An apparatus for treating a treatment site in a blood vessel, the apparatus comprising:
-
an elongated tubular member including a distal portion;
an first deployable structure connected to the distal portion of the tubular member, the first deployable member adapted to be deployed and engage the blood vessel at a position proximal or distal of the treatment site; and
a second deployable structure connected to the distal portion of the tubular member, the second deployable member adapted to be deployed adjacent the treatment site to create movement adjacent the treatment site. - View Dependent Claims (42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64)
