Publication number: 20210178130Abstract: An example apparatus embodiment includes a catheter body and an inflatable balloon having longitudinal edges sealed to the catheter body. The balloon may be configured to extend farther outward from an outer surface of the catheter body in a first direction when inflated than a second direction opposite the first direction. The catheter body may be formed with a lumen for controlling the balloon inflation, another lumen for transporting fluid to and from a diagnostic or therapeutic site in a patient's body, and yet another lumen for transporting a therapeutic or diagnostic instrument or other payload.Type: ApplicationFiled: January 24, 2020Publication date: June 17, 2021Inventor: Ray Betelia

Patent number: 10898695Abstract: An apparatus is provided that is operable in different modes to perform various functions for treating a body lumen. The apparatus includes a shaft including proximal and distal ends, a lumen extending there between, and a balloon on the distal end. The apparatus includes a valve on the distal end that selectively opens or closes an outlet communicating with the lumen. With the valve open, fluid introduced into the lumen exits the outlet into a body lumen. With the valve closed, fluid introduced into the lumen expands the balloon. The valve may be biased to be closed, e.g., by a spring element disposed within the balloon. Optionally, the apparatus also includes an actuator for expanding a helical member within the balloon interior, e.g., either before or after expanding the balloon, such that the helical member and balloon may adopt an expanded helical shape for removing material within a body lumen.Type: GrantFiled: November 21, 2017Date of Patent: January 26, 2021Assignee: ARROW INTERNATIONAL, INC.Inventors: Jeffrey A. Krolik, Gwendolyn Watanabe, Juan Domingo, Ray Betelia, James H. Dreher, Daryush Mirzaee, Lucas Fernandez

Patent number: 10624656Abstract: Apparatus and methods are provided for delivering fluid into a body lumen during a medical procedure. A distal end of an apparatus may be introduced into a body lumen, and a valve on the distal end may be opened to deliver fluid through a first lumen into the body lumen, e.g., contrast and/or other diagnostic or therapeutic agents. The valve may be closed, and a procedure may be performed within the body lumen, e.g., using a treatment element carried on the distal end. For example, the treatment element may include a balloon that may be inflated when fluid is delivered through the first lumen with the valve closed. Optionally, a prosthesis, energy source, drug platform, and the like may be carried by the balloon for treating the body lumen. In various embodiments, the valve may be located proximal or distal to the treatment element.Type: GrantFiled: September 7, 2017Date of Patent: April 21, 2020Assignee: Arrow International, Inc.Inventors: Jeffrey A.

Publication number: 20050171478Abstract: Medical devices/methods are described that include catheter systems for crossing total occlusions in vasculature. The catheter systems are for use with numerous guide wires to direct the wires from the extraluminal or subintimal space back into a blood vessel lumen after the wire has entered the subintimal space. The catheter systems comprise a catheter body having at least one lumen configured to track over a wire. An endpiece that includes at least one port in communication with the lumen couples to the distal region of the catheter body. A working element is configured to deploy through the port for delivery from a location within the extraluminal space to locations within the vessel true lumen when advanced distally through the port. A distal region of the catheter body assumes first or second configurations when the working element is retracted into the catheter body.Type: ApplicationFiled: April 12, 2004Publication date: August 4, 2005Inventors: Matthew Selmon, Kurt Sparks, Ray Betelia, Ben Clark, Jason Kaiser, Rob Deckman, Erik Thai
