CATHETER DEVICE WITH LOCAL MAGNETIC RESONANCE IMAGING COIL AND METHODS FOR USE THEREOF
摘要
A catheter device for deploying a local magnetic resonance imaging (MRI] coil is provided. The catheter device includes an outer catheter shaft having a lumen extending from a proximal end to a distal end and an inner catheter shaft having a lumen extending from a proximal end to a distal end. The outer and inner catheter shafts are movably engaged such that one can move relative to the other. A plurality of non-metallic filaments are coupled on one end to the outer catheter shaft and coupled on another end to the inner catheter shaft. The plurality of non-metallic filaments are intertwined to form a braid, to which a local MRI coil is coupled. The local MRI coil is configured to have a circular shape when the braid is in a deployed position. Additionally, motion tracking coils can be coupled to the braid to provide motion tracking information for motion compensation.
