摘要： An example device for detecting intravenous (IV) infiltration by identifying leaks and swelling at the patient skin. The device uses skin swelling to displace alignment of overlapping layers to produce a pattern or indication of swelling. Leakage is detected through the use of a conduit to wick liquid away from an insertion site and react with a dye or reagent to produce a color change that makes a clear visible indication of leaking. The detection methods provide visible markers without occluding visibility of the insertion site for the IV therapy.

摘要： Disclosed herein is a loop-forming guidewire system. According to embodiments of the invention, a loop-forming guidewire system may comprise a guidewire having at least one area of increased flexibility, a control tube external to the guidewire, and a control wire having two ends, the distal end connected to the distal end of a guidewire and the proximal end configured to be located external to the patient. Motion of the control wire in the proximal direction relative to the guidewire may bend a region of increased flexibility of a guidewire to form a circular or oval shaped loop which can then be securely lodged in a lumen of an animal through distal advancement of both the control wire and the guidewire.

摘要： In one embodiment, a sensing guidewire for performing atraumatic intravascular physiologic measurements includes an elongated core wire and a sensor disposed at a distal end portion thereof. A flexure is disposed in the core wire proximal to the sensor housing. The flexure is substantially more flexible than regions of the core wire disposed on either side of the flexure, and enables a distal end portion of the guide wire to conform to and rest against a wall of vascular structure, such as an aneurism, without exerting an undue outward pressure thereon in response to making any contact with the wall.

摘要： A guidewire is disclosed that is constructed using tubular members that create a hollow lumen that runs from the proximal end of the guidewire to a window towards the distal end of the wire. This internal lumen is filled with a fluid that allows pressure exerted at the window to exert pressure at the proximal end of the guide wire proportional to the pressure exerted at the window. This pressure exerted at the proximal end of the guidewire is measured using a pressure transducer external of the guidewire. The pressure transducer converts the measured pressure into an electrical signal that is proportional to the pressure at the window. The electrical signal is manipulated to correct for errors that are due to the pressure signal traveling though the inner lumen of the guidewire to ensure the electrical signal matches the pressure exerted at the window.
