Abstract
Described are methods and systems and system components useful for percutaneously delivering or retrieving vascular implant devices, such as filters, utilizing intravenous ultrasound (IVUS) imaging alone or in combination with external (e.g. transabdominal) ultrasound or other imaging technology. Implants deliverable by such systems, such as vena cava or other vascular filters, can have two or more echogenic markers spaced at such a distance that they are separately discernible by IVUS and/or external ultrasound imaging.
Claims19
A system for ultrasound guidance, comprising:
- a computer processor for receiving signal data from an intravascular ultrasound probe mounted on an elongate percutaneously introducible device having a distal tip located distally of the intravascular ultrasound probe and generating ultrasound images using the signal data, wherein the intravascular ultrasound probe travels correspondingly with the elongate percutaneously introducible device;
- a visual display device electronically connected to the computer processor;
- and
- said computer processor and display device configured to display on the visual display device two-dimensional, real time images generated by the computer processor using the signal data simultaneously with and spaced from a three-dimensional image generated from prior-acquired intravascular ultrasound image signal data from the intravascular ultrasound probe, and wherein the computer processor and visual display device are configured to display within the three-dimensional image on the visual display a graphical image representing a position of the intravascular ultrasound probe, and wherein the computer processor is configured to perform a comparison of the two-dimensional, real time images to the prior-acquired intravascular ultrasound image signal data and to position the graphical image within the three-dimensional image based on the comparison, wherein the computer processor and visual display device are configured to display on the visual display device a reference scale, wherein the reference scale is generated from the prior-acquired three-dimensional ultrasound image and is correlated to the real time two-dimensional image.
