600/463, With acoustical or display imaging600/439, With therapeutic device600/471, Tool (e.g., ablation, abrasion, cutting)606/159Blood vessel, duct or teat cutter, scrapper or abrader
A self contained ultrasound device for the delivery of therapeutic and other types of tools to be visualized in an ultrasound-type environment within the blood before, during, and after an intervention includes a catheter having a catheter body with a proximal and distal ends. The catheter contains an ultrasonic transducer proximate its distal end. An access port is provided in the catheter for delivery of a therapeutic device or the like to proximate the distal end of the catheter body. A guide wire port is further provided for insertion therethrough of a guide wire.
