Patent number: 8251948Abstract: A catheter for delivering an agent to an area of treatment is presented. The catheter includes a catheter body, a balloon assembly coupled to the catheter body, a first lumen, and a second lumen. The balloon assembly has spaced-apart balloons that define an area between the balloons. The first lumen extends along the catheter body to pass an inflation material to the balloons to control an inflation level of the balloons. The second lumen extends along the catheter body and having an outlet in the area between the balloons. There may be a third lumen for bypassing a biological fluid such as blood while the catheter is being used. The method of using this catheter is also presented. The method entails simultaneously inflating the balloons to isolate a treatment area and adding an agent to the treatment area through one of the lumens.Type: GrantFiled: March 17, 2009Date of Patent: August 28, 2012Assignee: Vascular Designs, Inc.Inventor: Robert J. Goldman

Publication number: 20100114021Abstract: The present invention relates to a multi-function catheter assembly for treating arterial plaques. The multifunction catheter comprises a flexible tubular catheter body, an inflatable balloon assembly capable of multi-stage inflation at a distal end of the catheter body, at least one fluid delivery conduit formed on the catheter body, and at least one balloon control conduit formed within the catheter body. The balloon, when inflated to a first stage inside a vessel at the treatment site, defines a chamber between the balloon and the vessel wall. The at least one fluid delivery conduit is adapted to permit the delivery of an agent into the chamber to dissolve a plaque. After the removal of the plaque, the balloon is further inflated to a second stage to install a stent in the space that is vacated by the plaque. The stent can be a pre-manufactured stent or a customized stent formed by filing the space between the balloon and the treated vessel wall with a fluent composition that is solidified in situ.Type: ApplicationFiled: January 11, 2010Publication date: May 6, 2010Applicant: Vascular Designs, Inc.Inventor: J.
