Publication number: 20110284498Abstract: A dilatation balloon is fabricated according to a process that forms cavities and indentations in the balloon and/or catheter sections. A length of tubing is axially elongated and radially expanded in a form to provide the requisite biaxial orientation and strength. Then, an excimer laser or another type of laser or mechanical material removal tool is used to remove the polymeric material, virtually without thermal effects. Cavities in the sleeve sections of the balloon are defined and if desired, indentations in the cone sections are defined. Material removal, particularly near the balloon sleeves enables a thinner, more flexible bonding area between the catheter shaft and the balloon. Further, the indentations along the cone sections enables tighter wrapping of the balloon for a reduced delivery profile. Rigidity near the sleeves is reduced for better maneuverability of the catheter in tortuous passageways.Type: ApplicationFiled: June 2, 2011Publication date: November 24, 2011Applicant: Abbott LaboratoriesInventors: Boris Warnack, Judith Hartwig, Silke Pschibl, Travis Richard Yribarren, Randolf Von Oepen, Thomas Rieth, Lorcan Coffey, Arik Zucker

Publication number: 20080140174Abstract: A variety of methods are described that pre-condition a balloon used in a balloon catheter in order to increase its flexibility. Generally, the membrane that forms the balloon is crumpled in order to induce a large number of irregular crumples in the balloon. The crinkling of the balloon improves its flexibility and thus the flexibility of the catheter. Most typically, torsion and/or compression are applied to the balloon membrane in order to induce the crumpling. The described crumpling can be used to increase the flexibility of a balloon of a given strength in a variety of catheters, including angioplasty catheters and stent delivery catheters. In stent delivery catheters, the resulting crinkles also have the additional benefit of improving stent retention.Type: ApplicationFiled: August 17, 2006Publication date: June 12, 2008Inventors: Randolf von Oepen, Lorcan Coffey, Thomas Rieth, Travis R.

Publication number: 20080097404Abstract: Various improved catheter marking arrangements are described. In a first aspect of the invention, a first longitudinally extending radiopaque marker is positioned on the catheter. A second longitudinally extending radiopaque marker is positioned opposite the first marker at a rotational orientation that is approximately 180 degrees offset from the first marker. The second marker has a length that is sufficiently different from the first marker such that a surgeon utilizing the catheter in a surgical procedure would be able to readily differentiate the first and second markers in a fluoroscopic image based on their respective lengths in order to determine the rotational orientation of the catheter. In some embodiments, the catheter includes a lumen that has a side port that opens to a side of the catheter. The first marker is composed of a pair of axially aligned marker segments located on opposite ends of the side port.Type: ApplicationFiled: August 16, 2006Publication date: April 24, 2008Inventors: Travis R.

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

Publication number: 20070021685Abstract: A guidewire apparatus for a medical device that includes an expandable guidewire section that can be locked in an expanded state. In one use, the expandable section can be temporarily locked to a working element of a medical device to facilitate the transmission of torque from the guidewire to the medical device. Hence, this configuration may be utilized to aid in orientation of the working element with a vessel side branch by providing the user with the ability to apply a rotational force to the distal end of the stent delivery system. Another use includes docking the expandable section near an opening into a guidewire lumen at the catheter tip. This configuration is particularly useful in forming a smooth transition between the guidewire and the catheter tip to reduce the phenomenon of fish-mouthing.Type: ApplicationFiled: May 4, 2006Publication date: January 25, 2007Applicant: Abbott Laboratories Abbott Vascular DevicesInventors: Randolf Oepen, Travis Yribarren, Thomas Rieth, Lorcan Coffey, Arik Zucker
