Patent number: 8444685Abstract: A rapid exchange stent delivery catheter includes an inner tubular member having a proximal portion, a distal portion, a stent holding portion located adjacent the distal portion of the inner member, and a guide wire lumen extending from a proximal guide wire opening disposed distal of the proximal portion of the inner member to a distal guide wire opening disposed at a distal end of the inner member. The proximal guide wire opening has a first length. An outer tubular member is slidably disposed about the inner member. The outer member has a proximal portion, a distal portion, and a guide wire opening disposed distal of the proximal portion of the outer member. The guide wire opening of the outer member has a second length that is shorter than the first length and a guide wire ramp extends into, and is movable along the first length.Type: GrantFiled: December 17, 2008Date of Patent: May 21, 2013Assignee: Boston Scientific Scimed, Inc.Inventors: Michael Gerdts, Mary Bronson, August Powell

Publication number: 20090159189Abstract: Alternative designs, materials, and methods of making and using catheter manifolds. Some embodiments are related to a balloon catheter including a catheter shaft having a proximal portion and a distal portion. The shaft includes an outer tubular member defining a lumen and having a proximal end and a distal end. The shaft also includes an inner tubular member defining a lumen and having a proximal end and a distal end. The inner tubular member is disposed at least partially within the outer tubular member such that the proximal end of the inner tubular member extends proximally from the proximal end of the outer tubular member. A catheter manifold is molded about a portion of the outer tubular member and a portion of the inner tubular member, and a balloon assembly attached to the distal portion of the shaft such that the balloon assembly is in fluid communication with at least one of the lumens.Type: ApplicationFiled: February 26, 2009Publication date: June 25, 2009Applicant: BOSTON SCIENTIFIC SCIMED, INC.Inventors: GREGORY OLSON, AUGUST POWELL
