Publication number: 20110077731Abstract: A stent delivery system having multiple stents in a single delivery catheter, configured for delivering and deploying at least some of the stents in a patient's anatomy. A reversibly collapsible stent stop secured to the inner tubular member abuts a proximal end of a first distal stent prior to deployment of the first stent, and is configured to radially collapse as the inner tubular member is proximally withdrawn into the outer tubular member through the second collapsed stent, and radially self expand along at least a section thereof at a location proximally adjacent to a proximal end of a second collapsed stent prior to deployment of the second stent after deployment of the first stent. One or two stent retainer are attached to the shaft of a stent delivery catheter to prevent longitudinal shifting of the stent along the longitudinal axis of the catheter.Type: ApplicationFiled: September 25, 2009Publication date: March 31, 2011Applicant: ABBOTT CARDIOVASCULAR SYSTEMS INC.Inventors: Henry H. Lee, Kevin M. Seiki, John Whitfield, John Papp, Benjamin Huter

Publication number: 20080091231Abstract: A self-expanding cage for use in conjunction with an embolic filtering device includes a circumferential member adapted to expand from an unexpanded position to a expanded position within the patient's body vessel. A proximal strut and distal strut are attached to the circumferential member to form the cage. A plurality of proximal and distal struts may be attached the circumferential member. Additionally, a second circumferential member can be attached to the first circumferential member. Each circumferential member can be connected by a single or a plurality of connecting struts. One embodiment of the cage utilizes a single wire to form to the cage. A delivery system attached to the single wire cage moves the cage and its associated filter element between the expanded and unexpanded positions through relative movement of the distal delivery system.Type: ApplicationFiled: December 14, 2007Publication date: April 17, 2008Applicant: ADVANCED CARDIOVASCULAR SYSTEMS, INC.Inventors: William Boyle, William Harrison, Benjamin Huter, Scott Huter, Paul Muller, John Papp

Publication number: 20070276429Abstract: A system for enabling the insertion and removal of an embolic protection device, for capturing and retaining embolic debris which may be created during the performance of a therapeutic interventional procedure in a stenosed or occluded region of a blood vessel. The system, in an embodiment thereof, enables the device to be snap-fitted so as to engage the distal end of a guide wire, to provide a reference for positioning the device at a location distal to the interventional procedure site, and to enable an end of the device to be in tension, enabling a portion of the device to be in tension and another portion to be in compression, so as to assist in bending thereof in tortuous vasculature.Type: ApplicationFiled: June 26, 2007Publication date: November 29, 2007Applicant: ADVANCED CARDIOVASCULAR SYSTEMS, INC.Inventors: Benjamin Huter, John Papp, Anuja Patel, John Whitfield

Publication number: 20070250108Abstract: A self-expanding cage for use in conjunction with an embolic filtering device includes one or more circumferential members adapted to expand from an unexpanded position to a expanded position within the patient's body vessel. At least one proximal strut and at least one distal strut are attached to the circumferential member to form the basket. The circumferential member may include a plurality of bending regions which enhance the ability of the circumferential member to move between the unexpanded and expanded positions. The proximal and distal struts can be attached to one of the bending regions. When two or more circumferential members are utilized, each member may be connected by a connecting strut which may be connected at a bending region. The connecting strut can be a straight segment or may have a non-linear shape to provide additional flexibility. The expandable cage can be mounted to a elongated member, such as a guide wire, and can be either permanently mounted or rotatably mounted thereto.Type: ApplicationFiled: June 25, 2007Publication date: October 25, 2007Applicant: ADVANCED CARDIOVASCULAR SYSTEMS, INC.Inventors: William Boyle, Benjamin Huter, Scott Huter, John Papp

Publication number: 20070208374Abstract: An embolic protection device for use in a blood vessel when an interventional procedure is being performed in a stenosed or occluded region to capture any embolic material which may be created and released into the bloodstream during the procedure. The device includes a filtering assembly having a self-expanding strut assembly and a filter element attached thereto. In one embodiment, the filtering assembly is attached to the distal end of a guide wire and is deployed within the patient's vasculature as the guide wire is manipulated into the area of treatment. A restraining sheath placed over the filtering assembly in a coaxial arrangement maintains the filtering assembly in its collapsed position until it is ready to be deployed by the physician. Thereafter, the sheath can be retracted to expose the filtering assembly which will then self-expand within the patient's vasculature.Type: ApplicationFiled: May 11, 2007Publication date: September 6, 2007Applicant: ADVANCED CARDIOVASCULAR SYSTEMS, INC.Inventors: William Boyle, Andy Denison, Benjamin Huter, Scott Huter, Richard Stack, Kent Stalker, Christopher Tarapata, John Whitfield

Publication number: 20070156169Abstract: An expandable frame for an embolic filtering device used to capture embolic debris in a body vessel includes a first half frame having a first control arm connected to a second control arm by a partial loop and a second half frame having a first control arm connected to a second control arm by a partial loop. The partial loops cooperatively form a composite loop for attachment of a filtering element which will expand in the body vessel to capture embolic debris entrained in the fluid of the vessel. The lengths and positioning of the first and second control arms of each half frame can be varied to create an expandable frame which conforms to the size and shape of the body vessel in which the filtering device is deployed. Additionally, the radius of the partial loops, along with the length of the arc of the partial loops, can be varied on each of the frames to create a composite filtering assembly that can easily adapt to the size and shape of the body vessel.Type: ApplicationFiled: January 17, 2007Publication date: July 5, 2007Inventors: Andy Denison, William Harrison, Benjamin Huter, Scott Huter, John Papp, Steven Saville, Kent Stalker

The partial loops cooperatively form a composite loop for attachment of a filtering element which will expand in the body vessel to capture embolic debris entrained in the fluid of the vessel. The expandable frame and filtering element can be mounted on a filter support structure, such as a coiled wire, and mounted on a guide wire. The expandable frames includes an articulation region which helps to distribute the strain which can be developed when the frame moves between an expanded and deployed position. The expandable frame may include further strain distributing bends which help distribute strain and increase the bendability of the frame.Type: ApplicationFiled: January 11, 2007Publication date: May 31, 2007Inventors: Scott Huter, John Papp, Douglas Gesswein, Wayne Cornish, Peter D'Aquanni, Thomas Tokarchik, Andy Denison, Kevin Magrini, Benjamin Huter, Charles Peterson, William Boyle, Mark Richardson, Ryan Grandfield, Kathern Lind

Publication number: 20060265002Abstract: A filtering device for capturing and removing embolic debris from a body vessel and a system for insertion and removal of the filtering device to facilitate an interventional procedure in a stenosed or occluded region of a body vessel. The filtering device is adapted to be expandable in the body vessel, allowing blood to pass therethrough while maintaining apposition with the body vessel wall and capturing embolic material released into the bloodstream during the interventional procedure, and to be collapsible to remove the captured embolic material from the body vessel. The filtering device includes a guidewire, an expandable cage assembly secured to the guide wire, filter material secured to the expandable cage assembly, and at least one hinge, the hinge allowing the expandable cage assembly to bend independent from the guide wire.Type: ApplicationFiled: August 1, 2006Publication date: November 23, 2006Inventors: Benjamin Huter, Kevin Magrini, John Papp
