Patent number: 9668817Abstract: One aspect of the present disclosure involves a method. The method includes retrieving, from a diagnostic medical device, identification information that identifies a feature of the diagnostic medical device. A proprietary signal is generated in response to the identification information. The proprietary signal is sent to a medical measurement system to facilitate an unlocking of one or more programs to be executed on the medical measurement system. Another aspect of the present disclosure involves a method. The method includes detecting, through an electronic interface device, a coupling of a remote diagnostic medical device. Thereafter, a proprietary signal is received from the electronic interface device. An identity feature of the remote diagnostic medical device is ascertained based on the proprietary signal. One or more programs are unlocked for execution if the identity feature of the remote diagnostic medical device matches a predetermined identity feature.Type: GrantFiled: March 14, 2014Date of Patent: June 6, 2017Assignee: Volcano CorporationInventors: David Anderson, Douglas E. Meyer

Patent number: 9247909Abstract: 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.Type: GrantFiled: December 29, 2011Date of Patent: February 2, 2016Assignee: Volcano CorporationInventor: Douglas E. Meyer, Jr.
