Patent number: 10039659Abstract: 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: GrantFiled: June 13, 2016Date of Patent: August 7, 2018Assignee: ABBOTT CARDIOVASCULAR SYSTEMS INC.Inventors: Michael Bialas, Marc Gianotti, John E. Papp, John Simpson, Wouter Erik Roorda, Matthew Gillick, Michael L. Green, David P. Strauss, Duane M. DeMore, Robert P. Barbier

Patent number: 8278593Abstract: A method for making a device includes providing a tubular member which will be formed into the device, masking at least a portion of the inner surface of the tubular member with a removable sacrificial material, selectively removing a portion of the tubular member and sacrificial material using a laser device, and mechanically removing the sacrificial material from the inner surface of the tubular member. The method may also include applying a chemical solution to the tubular member and sacrificial material which primarily attacks the either the tubular member or sacrificial material.Type: GrantFiled: April 25, 2011Date of Patent: October 2, 2012Assignee: Abbott Cardiovascular Systems Inc.Inventors: Michael Bialas, John A.
