Patent number: 10531906Abstract: A medical vapor system and method is provided. The medical vapor system can include a fluid conduit having an inlet, an outlet and a heating section, the inlet being adapted and configured to be connected to a source of liquid water, a resistance heater disposed and configured to generate heat and conduct the heat to the heating section of the fluid conduit to vaporize liquid water flowing through the heating section, a power supply operatively connected to the heater, and a controller adapted to control production of water vapor by the system. Methods of use are also provided.Type: GrantFiled: February 2, 2016Date of Patent: January 14, 2020Assignee: Uptake Medical Technology Inc.Inventors: Joshua Pieter Kroon, Erik Henne, Daniel Lawrence Reddy, Robert Alan Mest, Ryan Welty

Patent number: 9186170Abstract: A rotational atherectomy device that includes an expandable head that can clean a blockage from vessel larger than its rest diameter, in which the drive shaft may rotate in two opposite directions and may have different abrasive characteristics for each rotation direction. In one direction, the head may be configured for cutting and/or slicing, which may be well suited to removing particularly soft blockage material. In the other direction, the head may be configured for grinding, scraping and/or sanding, which may be well suited to removing particularly hard blockage material. The head includes one or more arms that are pivotally or hingedly attached to the drive shaft. One or more abrasive elements are disposed on or are attached to the one or more arms. The abrasive elements have a cutting feature, such as a sharpened edge that cuts like a razor blade when the drive shaft is rotated in the “cutting” direction.Type: GrantFiled: May 14, 2009Date of Patent: November 17, 2015Assignee: Cardiovascular Systems, Inc.Inventors: Ryan Welty, Charles A. Plowe, Cassandra A. Piippo, Todd James Bakken, Jesse C. Darley

Patent number: 8225474Abstract: A crimping fixture for crimping a stent onto a balloon of a catheter is disclosed. The crimping fixture includes a flexible elastomeric body having a crimping lumen and one or more inflation lumens extending through the flexible elastomeric body. The flexible elastomeric body is elastically stretched such that a pre-crimped stent may be placed in the crimping lumen. The inflation lumens are then pressurized with a fluid to impart an inward crimping force onto the stent to crimp the stent to a balloon.Type: GrantFiled: May 30, 2008Date of Patent: July 24, 2012Assignee: Boston Scientific Scimed, Inc.Inventors: Benjamin Arcand, Ryan Welty
