Patent number: 10238453Abstract: An endovascular laser treatment device for causing closure of a blood vessel uses an optical fiber adapted to be inserted into a blood vessel. An inner sleeve is arranged around a distal portion of the optical fiber core such that both distal ends of the inner sleeve and the optical fiber core form an enlarged light emitting face. The enlarged emitting face provides substantially lower power density while providing the same amount of total energy during a treatment session. An outer sleeve arranged around the inner sleeve acts as a spacer to position the light emitting face away from an inner wall of the blood vessel. The enlarged light emitting face and the outer sleeve acting as a spacer reduces the possibility of thermal run-away and device damage, and reduce the possibility of vessel perforations, leading to less bruising, post-operative pain and other clinical complications.Type: GrantFiled: October 15, 2015Date of Patent: March 26, 2019Assignee: AngioDynamics, Inc.Inventors: William M. Appling, Ralph A. Meyer, Theodore J. Beyer, William C. Hamilton, Jr., Joe D. Brown

Patent number: 9055996Abstract: A compact retrievable blood clot filter has a filter section, a releasable lock and an alignment section connected to the filter section. Alignment ribs of the alignment section have releasable upstream ends that are locked to the filter by the releasable lock. The releasable upstream ends of the alignment ribs are capable of being released from the releasable lock so that during retrieval of the filter, the alignment ribs can slide through the endothelial tissue that may have grown around the alignment ribs.Type: GrantFiled: July 23, 2009Date of Patent: June 16, 2015Assignee: AngioDynamics, Inc.Inventors: William A.

Patent number: 8864755Abstract: An endovascular treatment method for causing closure of a blood vessel is provided. The method includes inserting into a blood vessel an optical fiber having a core through which a laser light travels and a spacer sleeve arranged around a distal portion of the core. A distal end of the core defines an enlarged light emitting face, which advantageously provides substantially lower power density while providing the same amount of total energy during a treatment session. After the insertion, laser light is applied through the light emitting face while the inserted optical fiber and spacer sleeve are longitudinally moved. The spacer sleeve positions the light emitting face away from an inner wall of the blood vessel and application of the laser light causes closure of the blood vessel.Type: GrantFiled: August 3, 2012Date of Patent: October 21, 2014Assignee: AngioDynamics, Inc.Inventors: William M.

Patent number: 8317773Abstract: A vascular access catheter is disclosed that has a catheter shaft with a distal end portion with a distal tip having a sloped face that is positioned at an acute angle from the distal tip relative to a longitudinal axis of the catheter shaft. A first, second, and third lumen extend longitudinally through the catheter shaft. The third lumen is configured for receiving a guidewire and may extend a partial length of the catheter or substantially the entire length of the catheter. The first lumen has an aperture located in the angled edge distal end portion of the catheter next to the distal tip and communicates with the first lumen. The second lumen has an aperture that is positioned in the outer surface of the catheter shaft that is in communication with the second lumen, and is spaced proximally from the first lumen aperture.Type: GrantFiled: November 7, 2006Date of Patent: November 27, 2012Assignee: Angio Dynamics, Inc.Inventors: William M.

Patent number: 8057460Abstract: A multiple tube catheter, such as a hemo-dialysis catheter, has first and second tubes which are attached to each other over a zone by one or more longitudinally extending wires which joins the two tubes over that zone. When a catheter is implanted in the patient, the attached zone is within the patient so that the catheter cannot be removed or advanced. When the catheter is to be removed, the longitudinally extending wire or wires are pulled proximally out of the tubes involved so that the two tubes can be separated and individually removed. A flexible separating prong within the patient and proximal of the zone holds the tubes apart to further assure that the catheter cannot be moved.Type: GrantFiled: October 22, 2007Date of Patent: November 15, 2011Assignee: AngioDynamics, IncInventors: Eamonn P. Hobbs, William M. Appling, Angelo J. Tarricone, Theodore J. Beyer

Publication number: 20110224618Abstract: A catheter retention assembly and method of use with a catheter. The assembly has a carrier system and a cuff positioning device with an in-growth cuff and a lumen having an inner wall adapted to be mounted on the outer surface of the catheter, and a carrier system with an inner surface and an outer surface in contact with the inner wall of the cuff positioning device. The carrier system holds the lumen in a first radial state. When the carrier system is removed, the lumen contracts to a second radial state, and the inner wall of the cuff positioning device provides sufficient surface adherence to the outer surface of the catheter, so as to maintain the position of the cuff positioning device relative to the catheter, and to allow for catheter exchange.Type: ApplicationFiled: May 19, 2011Publication date: September 15, 2011Inventors: Joel E.

Publication number: 20090157051Abstract: A vascular access catheter that has a substantially distal end portion that has a distal tip. The distal end portion has a sloped face in the distal portion of the catheter, an outflow lumen aperture, and a second inflow lumen aperture. The outflow lumen aperture is substantially completely open in the sloped face and exits the distal portion adjacent the distal tip. The catheter has a guidewire lumen that is located at least in the region of the distal portion of the catheter and is capable of receiving a guidewire. The guidewire lumen has a proximal aperture and a distal aperture that extends distally of the outflow lumen aperture. The guidewire distal aperture exits at the distal most edge of the distal end portion. The guidewire lumen may extend a partial length of the catheter or substantially the entire length of the catheter. The catheter distal portion may be substantially straight or curved.Type: ApplicationFiled: February 25, 2009Publication date: June 18, 2009Inventors: William M. Appling, Theodore J. Beyer, Carol L.
