Publication number: 20080051705Abstract: A bifurcation stent delivery catheter includes a first branch balloon, a second branch balloon adjacent the first branch. A centering balloon is optionally disposed distal of the second branch balloon. The balloons are coupled by a coupling device to a main shaft of a catheter. The coupling device allows axial forces to be transmitted from the main shaft to the balloons while allowing the balloons to rotate axially relative to the main shaft with ease. The coupling device functions as an axial rotational joint. The coupling device can have a flexible tubular member that connects the balloons to the main shaft, the tubular member having a torsional flexibility greater than that of the main shaft. The coupling device can have a tubular wall having a cut extending circumferentially around the tubular wall and protective boot covering the cut. The coupling device can have a wound member that allows the axial rotation.Type: ApplicationFiled: August 20, 2007Publication date: February 28, 2008Inventors: Randolf Von Oepen, Lorcan Coffey, Thomas Rieth, Richard Newhauser, Travis Yribarren, Bruce Wilson

Publication number: 20070288081Abstract: Disclosed are stent delivery apparatus and methods for moving a balloon catheter carrying a stent through a body vessel without the stent slipping from the balloon are provided. In general, the stent delivery system includes a stent stopper that impedes the stent from slipping from the balloon. The stent stopper is sized to serve as a barrier to the stent as it is carried on the balloon. In a specific embodiment, the stent stopper is formed from a material that encircles the proximal end of the balloon and abuts the proximal end of the stent. The stent stopper material expands with expansion of the balloon and collapses with deflation of the balloon. In some embodiments, the stent stopper material has a thickness that is about equal to or greater than the thickness of the stent so as to form a barrier against the stent and impede the stent from slipping off the proximal end of the balloon.Type: ApplicationFiled: May 10, 2007Publication date: December 13, 2007Applicant: ABBOTT LABORATORIESInventors: Randolf Oepen, Arik Zucker, Travis Yribarren, Thomas Rieth, Lorcan Coffey
