US Patent:

41955196, Apr 1, 1980

Filed:

Aug 31, 1978

Appl. No.:

5/938624

Inventors:

John A. Replogle - Tempe AZ
Albert J. Clemmens - Mesa AZ
Edward D. Bell - Tempe AZ

Assignee:

The United States of America as represented by the Secretary of
Agriculture - Washington DC

International Classification:

G01F 120

US Classification:

73215

Abstract:

Water flow rate in channelized, flowing bodies of water is measured by first obstructing the flow of water in the body causing a rise in the water surface upstream from the obstruction. This rise in upstream water surface is communicated to a point above the obstruction and measured thereat. The measurement is then converted to a water flow rate. A device for measuring water flow rate includes means for producing an obstruction of water flow in the body of water thus causing a rise in the water surface upstream from the obstruction, means for communicating the rise in upstream water surface to a point above the obstruction, and means for measuring the rise at that point, all secured to a frame.

International Classification:

A61M 25/01

Abstract:

Disclosed herein are magnetically trackable stylets and methods thereof. A magnetically trackable stylet can include a stylet body including a core wire, a magnetic assembly, and an outer construction over the core wire and the magnetic assembly. The magnetic assembly can include one or more magnetic field-producing elements disposed alongside the core wire in a magnetically trackable distal portion of the stylet body. The outer construction, which can be an overmolded layer, a reflowed layer, a potting layer, or a shrink-wrapped layer, can be around the core wire and the magnetic assembly. The stylet body can be configured to be disposed in a lumen of a medical device such as a catheter for magnetically tracking a tip of the medical device in vivo without breakage of the stylet body due to bending-related fatigue. A method of such a magnetically trackable stylet can include a method of using the stylet.

International Classification:

A61M 25/00
A61M 1/00

Abstract:

Briefly summarized, embodiments disclosed herein are directed to apparatus and methods for removing an occlusion from an indwelling catheter. The system can include a pressurized fluid conduit for delivering pressurized fluid to an occlusion site, and ablating the occlusion. A negative pressure source in fluid communication with the catheter lumen can then aspirate the occlusion. The positive pressure source can provide a pulsed pressurized fluid to facilitate ablation. The system can also include tip tracking and tip location systems to ensure the pressurized fluid conduit does not extend beyond the catheter lumen, causing damage to the vasculature. The system can further include an ultrasound transducer, coupled with one of the catheter and the pressurized fluid conduit to provide ultrasonic wave energy to the occlusion to further facilitate ablation thereof.
