Multifunction intraluminal ultrasound catheter having a removable core with maximized transducer aperture |
摘要 |
A multi-function intraluminal ultrasound catheter assembly includes an axially disposed lumen having at least a first portion with a flat inner wall forming a "D-shaped" cross-section. An acoustic imaging window having a circular cross-section is connected to a distal end of the catheter assembly, wherein the cross-sectional dimension of the D-shaped portion of the lumen that extends from the flat inner wall is less that the available inner diameter of the imaging window. A flexible drive-shaft extends through the lumen and is connected to a transducer housing disposed in the acoustic imaging window area, the transducer housing having a substantially "D-shaped" outer perimeter, wherein the drive-shaft and connected transducer housing may thereby be retracted from the catheter assembly by first rotating the transducer housing until its D-shaped outer perimeter is substantially oriented with the D-shaped cross-section of the lumen. In a preferred embodiment, the transducer housing also includes a longitudinally disposed transducer mounting section configured such that the active surface of a transducer mounted therein is generally aligned across the maximal inner diameter of the acoustic imaging window.
