Publication number: 20180325712Abstract: Catheter for delivery of a medical device such as a stent or filter includes an inner tubular member and an outer tubular member movable relative to the inner tubular member. The outer tubular member is disposed at the distal end of the inner tubular member. The inner tubular member includes a fluid lumen defined therein, the fluid lumen having a fluid flow port directed to the exterior surface of the inner tubular member. A pressure chamber is defined by the inner tubular member, the outer tubular member, a proximal seal and a distal seal, and is in fluid communication with the fluid flow port, wherein fluid introduced through the fluid flow port and into the pressure chamber applies a force on the proximal seal to move the outer tubular member in a proximal direction allowing the medical device constrained by the outer tubular member to be released.Type: ApplicationFiled: July 24, 2018Publication date: November 15, 2018Applicant: ABBOTT CARDIOVASCULAR SYSTEMS INC.Inventors: Michael R. Bialas, John E. Papp, John Simpson, Wouter Erik Roorda, Matthew Gillick, Michael L. Green, David P. Strauss, Duane M. DeMore, Robert P. Barbier, Marc Gianotti

Patent number: 10022127Abstract: The disclosed subject matter describes systems and methods of delivering a therapeutic agent, such as a sclerosing agent, to the walls of a blood vessel to perform sclerotherapy. In an exemplary embodiment a catheter includes a guidewire catheter having at least one guidewire lumen extending therethrough and a slidable concentric tube disposed over the guidewire catheter. At least one bellow is coupled to the concentric tube and configured for conversion between an unexpanded and expanded configuration wherein movement of the concentric tube in a first direction causes the at least one bellow to expand and movement of the concentric tube in a second direction causes the at least one bellow to contract. Additionally, the concentric tube contains at least one port for delivery of a therapeutic agent, e.g. a sclerosing agent. The at least one bellow expands and contracts via mechanical forces.Type: GrantFiled: November 2, 2011Date of Patent: July 17, 2018Assignee: ABBOTT CARDIOVASCULAR SYSTEMS INC.Inventors: Wouter Erik Roorda, Michael Green, Neil Burkhart
