Abstract
The present invention relates to intravascular techniques for which pullback distance measurement is important, such as intravascular ultrasound (IVUS) imaging. The invention describes hardware, circuit architectures and methods for wireless transmission of data related to pullback distance of a catheter that is introduced into a vessel.
Claims31
A pullback distance sensor for intravascular ultrasound systems (IVUS), comprising:
- a housing defining a central opening configured to slidingly receive an IVUS catheter therethrough;
- a linear motion sensor disposed with the housing configured to detect motion of the IVUS catheter when moved through the housing central opening;
- and
- a wireless communications device disposed with the housing in communication with the linear motion sensor to receive and wirelessly transmit signals representing movement of the IVUS catheter detected by the linear motion sensor.
1 more element
An intravascular ultrasound system (IVUS), comprising:
- an IVUS patient interface module;
- an IVUS catheter extending from the patient interface module;
- an IVUS catheter introducer configured to receive the IVUS catheter;
- a pullback distance sensor configured to be disposed around the IVUS catheter and produce a wireless signal indicating pullback distance, wherein said wireless signal is received by an IVUS system controller.
1 more element
A method of measuring pullback distance in an intravascular ultrasound system (IVUS), comprising:
- placing a pullback distance sensor housing around an IVUS catheter;
- pulling the IVUS catheter through the pullback distance sensing unit;
- detecting a distance of travel of the IVUS catheter through the pullback distance sensor housing with at least a linear motion sensor disposed with said unit housing;
- and
- wirelessly transmitting a signal indicating said distance of travel from the pullback distance sensor housing to an IVUS system controller.
