Patent number: 11944331Abstract: A medical device may include an elongated body, a balloon positioned at a distal portion of the elongated body, and one or more pressure-wave emitters positioned along a central longitudinal axis of the elongated body within the balloon. The one or more pressure-wave emitters may be configured to propagate pressure waves radially outward through the fluid to fragment a calcified lesion at the target treatment site. The at least one of the one or more pressure-wave emitters may comprise an electronic emitter including a first electrode and a second electrode. The first electrode and the second electrode may be arranged to define a spark gap between the first electrode and the second electrode, and the second electrode may comprise a portion of a hypotube.Type: GrantFiled: September 13, 2023Date of Patent: April 2, 2024Assignee: FastWave Medical Inc.Inventors: Edward Anderson, Randy Beyreis, Scott Nelson, JiChao Sun, Brady Hatcher, Ae-Suk Pauling, Daryl Kiefer, Dannah Dean, Curtis Goreham-Voss, Parker Hagen, Tristan Tieso, Lauren Eno

Patent number: 11918285Abstract: A medical device may include an elongated body having a distal elongated body portion and a central longitudinal axis. The medical device may include a balloon positioned along the distal elongated body portion. The balloon may be configured to receive a fluid to inflate the balloon such that an exterior balloon surface contacts a calcified lesion within a patient's vasculature. The medical device may include one or more pressure wave emitters positioned along the central longitudinal axis of the elongated body. The one or more pressure wave emitters may be configured to propagate at least one pressure wave through the fluid to fragment the calcified lesion. At least one pressure wave emitter may include an optical fiber configured to transmit laser energy into the balloon. The laser energy may be configured to create a cavitation bubble in the fluid.Type: GrantFiled: May 23, 2023Date of Patent: March 5, 2024Assignee: Fast Wave Medical Inc.Inventors: JiChao Sun, Parker Hagen, Dannah Dean, Lauren Eno, Brady Hatcher, Curtis Goreham-Voss, Tristan Tieso, Edward Anderson, Scott Nelson, Dean Irwin, Bryan Goh, Charles Anthony Plowe, Randy Beyreis

Publication number: 20170261290Abstract: The disclosure generally relates to a wind indicating device. In various embodiments, the device can be used for wind detection and wind direction determination. The device can, in various embodiments, produce visible vapor and/or smoke. The visible smoke can interact with wind such that an operator can see which direction the wind is traveling and/or swirling. This can be beneficial for operators in the pursuit of game for hunting purposes, or in more general application in military actions.Type: ApplicationFiled: March 10, 2017Publication date: September 14, 2017Inventors: David Kristopher Bonine, Randy Nelson Yow

Publication number: 20160297235Abstract: A container assembly includes a container that may be slid onto a paint roller. The container is comprised of a resiliently deformable material wherein the container may be compressed onto the paint roller when the container is slid onto the paint roller. A plurality of ribs is attached to the container wherein each of the ribs engages the paint roller when the container is compressed onto the paint roller. Thus, the paint roller may be removed from a paint roller handle.Type: ApplicationFiled: April 10, 2015Publication date: October 13, 2016Inventor: Randy Nelson

Publication number: 20140358451Abstract: Methods and systems for detecting and quantifying signal peaks from ESI-TOF-MS data may include creating a signal model and a noise model for mass spectrometry (MS) data. The method may also include detecting a signal peak based, at least in part, on the signal model and the noise model for the MS data. The method may further include determining an amplitude of the detected signal peak based, at least in part, on the signal model and the noise model for the MS data.Type: ApplicationFiled: June 4, 2014Publication date: December 4, 2014Applicant: ARIZONA BOARD OF REGENTS ON BEHALF OF ARIZONA STATE UNIVERSITYInventors: Sai Buddi, Thomas Taylor, Randy Nelson, Chad Borges, Douglas Cochran

Patent number: 7027862Abstract: A method and device for transmitting a signal in an implantable medical device that includes a control unit and a first electrode and a second electrode positioned along a lead body. A connector block is positioned along an upper portion of a housing portion of the control unit, and a connector is positioned at a proximal portion of the lead body and is insertable within the connector block. A third electrode having a conductive element is positioned along the control unit in close proximity adjacent to the connector. The control unit transmits a signal between the first electrode and the second electrode and determines an alternate transmission path of the signal between the third electrode and one or both of the first electrode and the second electrode in response to the signal not being effectively transmitted between the first electrode and the second electrode.Type: GrantFiled: July 25, 2002Date of Patent: April 11, 2006Assignee: Medtronic, Inc.Inventors: Roger Dahl, Frank Dropps, Randy Nelson, Mark Stockburger

Patent number: 6726678Abstract: There is disclosed method and apparatus for retaining a reservoir for a therapeutic agent between the scalp and cranium of a subject, including providing a deformable pouch or rigid cylinder for dispensing the therapeutic agent from the reservoir to a location in the body of the subject. In one embodiment, a pump is used to pump the agent from the reservoir to the location in the subject's body. In another example embodiment, there is provided method and apparatus for forming at least one cavity in the cranium of the subject, and placing at least a portion of the pump in the cavity. Power is applied to the pump in a variety of ways.Type: GrantFiled: February 22, 2001Date of Patent: April 27, 2004Assignee: iSurgical, LLCInventors: Randy Nelson, Charles L. Truwit

Patent number: 5486011Abstract: A braking device for in-line skates including a resiliently biased, pivotally mounted load bearing wheel. The resilient element prevents contact between the wheel and a skate mounted braking surface during normal skating movements. The braking device is activated by exerting sufficient downward force on the load bearing wheel to overcome the resilient bias and thereby making frictional contact between the load bearing wheel and the braking surface.Type: GrantFiled: June 2, 1994Date of Patent: January 23, 1996Inventor: Randy Nelson
