    摘要: A porous implantable prosthesis is loaded with a substance for subsequent application to biological tissues. A method according to loading the substance to the porous prosthesis is provided. A first fluid in combination with an added substance is applied to the porous prosthesis. During the application, the first fluid containing the substance is capable of penetrating into prosthesis pores. The first fluid is removed and a second fluid is applied to the prosthesis. The second fluid is not capable of significantly penetrating into the pores. Prior to the application of the second fluid, the prosthesis can be immersed in a third fluid and agitated via mechanical perturbation techniques so that any of the substance gathered on the surface of the body, after the application of the first fluid, is removed. The third fluid should not be capable of dissolving the substance.

    摘要: An implantable medical device is disclosed having a helical construct including a set of spiral coils for local in vivo application of a therapeutic substance in a biological lumen. The helical construct is configured to apply less than 0.75 Bar of pressure to the biological lumen wall. The helical construct can have at least two sets of spiral coils having opposing helical directions. The device can be used for the treatment of vascular disorders such as restenosis and vulnerable plaque.
